<BR>Subject: <FONT COLOR=navy>suggestions and comments</FONT>
<P> Hi. read your "Getting started with Linux" and as it says it gives a brief
introduction to Linux. I've just started with linux, slakware, and comming from
windows there are some problems that are hard to figure out for yourself. First
of all it's this thing with devices. It took me two hours to get my cd-rom to
work. it's simple, but if you don't know how to mount your cd or you don't know
what a mounted hd/cd etc. is then it's quite tricky. And very often you need
your cd. Then it took me about three more hours to connect to internet. This
was also quite tricky comparing to just use the dial-up networking in windows.
Since much information about linux can be found on the internet it's not good
if you can't connect to it. I don't need this information, but I think these
two things are stuff you should put in your article, espescially how to connect
to an internet provider so you can serch for information on the web. daniel,

<BR>Subject: <FONT COLOR=navy>RedHat Linux 6.0 on a Tecra 8000</FONT>
<P> I recently attempted to install RedHat Linux 6.0 on a Toshiba Tecra 8000
notebook computer, and ran into a couple of problems. The first time I
installed it, everything appeared to be working properly, except the
keyboard keys were too "touchy". Many times, it would act like the keys
were sticking and print a character twice when it was pressed once.
(I've seen a couple other references to this issue on Usenet, but no
solutions were posted.)
<P> After I used Linux for several days on the notebook, I encountered a
situation where it didn't unlock the hard drive for read/write usage
after it finished performing a disk check with fsck, and subsequent
reboots failed due to the file system being stuck in "read only" mode.
<P> At this point, I decided to reformat and do another install from
scratch. This time around, the only changes I made were #1, not to put
the system in runlevel 5 so it started in X immediately upon boot-up,
and #2, enabled the apmd service for advanced power management. When
this install completed, I had problems right away where Linux would boot
- and then I wouldn't be able to type on the keyboard at all. (Every so
often, I was able to get control of the keyboard back - but only after
multiple reboots by hitting the power button on the notebook.)
<P> Has anyone else out there had any luck running Linux on a Tecra 8000?
Thanks, Tom.

<BR>Subject: <FONT COLOR=navy>IPChaining and Firewall rules</FONT>
<P>I have a small home network with 5 systems. I use Linux as my
proxy/firewall/dial-upon demand internet server and fileserver.
Before I upgraded to RH6 I could go to any site on the Web. Now with RH6 I
cannot get to some sites. ie: www.hotmail.com, www.outpost.com and
www.iomega.com to name a few. I can get to them from my Linux box but not
from the network. It sends the request and I see some data return but then
everything stops.
Here is my rc.firewall file:
<PRE>
# In rc.d make a script called rc.firewall. Make it mod 700.
# Makes it read/write/execute by owner(root)
# chmod 700 rc.firewall
#!/bin/sh
#
#rc.firewall - Initial SIMPLE IP Masquerade test for 2.2.3 kernels
#using IPCHAINS
#enable dynamic IP address
echo "1" > /proc/sys/net/ipv4/ip_dynaddr
/ipchains -M -S 7200 10 60
#
#Home Area Network
#192.168.28.0/24
#
ipchains -P forward DENY
ipchains -A forward -s 192.168.1.0/24 -j MASQ
ipchains -A forward -s 192.168.1.1/24 -j MASQ
ipchains -A forward -s 192.168.1.2/24 -j MASQ
ipchains -A forward -s 192.168.1.4/24 -j MASQ
ipchains -A forward -s 192.168.1.5/24 -j MASQ
</PRE>
<P> It looks like those sites don't like how my proxy/firewall is setup. This
only happened when I upgraded to RH6 and the 2.2 series of kernels.
<P> Any Ideas?????????

<BR>Subject: <FONT COLOR=navy>NFS boot RH6.0 Alpha?</FONT>
<P> I have a few old Alpha (UDB Multia) systems. All but one have no disks.
I'm hoping to figure out how to NFS boot one of them to become a diskless
firewall box. I noticed while configuring the kernel that there is an option
for NFS mount of the root, so I suspect all the software pieces are there -
just a small matter of configuring the server to listen for NFS requests. The
primary question I have, is: does anyone know if it is possible (through the
SRM or ARC consoles) to boot directly from the net, or do I have to boot a
floppy first that then boots from the net? I think there's also a way to put
milo into flash memory so I don't need the floppy for milo, but I don't know
how to tell milo to see the ethernet device. If I can't do it directly, how do
I do it indirectly? - it sure would be nice to have one (or more) diskless
alphas. On a somewhat related topic - is there any problem with adding a PCI
NIC card to the Multia to get a second ethernet device for my firewall effort?
Thanks in advance. /egp

<P> Hi, again. I've started saving my photos with a KODAK Picture Disk when I
have them developed. When I was using Windows this was no problem, but now
that I'm using Linux there is. KODAK does not support Linux with the software
that comes with their disks. When I save my images to my HD using MCOPY, the
images are upside down, but not reversed edge-wise. I've tried using gimp to
turn them 'right-side-up', and have managed to do just about everything else
with those images using gimp *but* that. (I fully admit I have no knowledge
about image manipulation, and really only want to know enough to accomplish
this one thing.) Can someone please tell me how to do this with gimp? I'm

<P> I'd like to ask about a strange thing I am getting when I run an SGI
application displayed on a Linux Xserver(PC )
<P>The Linux Xserver is running with RedHat 5.2 as following:
<PRE>
Driver "accel"
Device "Trio32/Trio64"

</PRE>
<P> If I open a tiff image (RGB 24bits) on the SGI it shows ok with all colors.
It is also OK if I open the same image on the Linux server using XV or Gimp.
<P> But if I display the image on the linux monitor while it is running on the
SGI the colors are not matching at all. The image resolution is perfect but
for the colors , the white is getting yellowish as if the green channel is
missing or getting dimmer or I can say as the blue and red channel are swapped.
<P> I used with a csh login on sgi:
<PRE>
setenv DISPLAY linux1:0
fm /var/tmp
</PRE>
<P> On linux The fm window appears and I doubleclick on a tiff image:

anybody help on this.

<P> I have been using fvwm95 on RH5.2. All the xterms have scrollbars on the
left side of their window. I recently installed SuSE6.1 and found that the
xterm windows in fvwm95 have no vertical scroll bars at all. This makes it
tough to look back through a screen's previous display. I tried the "Scroll
module" in the fvwm95 configuration menue but it scrolls the window itself
rather than the screen display history. I know the previous lines are there
because past display lines appear when I resize the window vertically.
<P> My question is how to I add vertical scroll bars to the xterm displays?

<P> By now you would have become the fifth person I have tried to contact
over the above mentioned subject. The closest I got was to a detailed

tried contacting the person through his e-mail, apparently it no longer

not get them to partition and install it on my computer for free as I
was leaving for China the next day. Now I am trying to do so with great

metalab.unc.edu etc does not serve my needs, so I need your expertise in
detail on how to go about it.

programs powerful, although it often is quite frustrating to learn to

<P> It's a shame to say, but I write this from a Windoze machine. The reason

solution?
<P> Another question I would be very grateful to have an answer to regards

<BR>Subject: <FONT COLOR=navy>Compiling problems</FONT>
<P> I am currently running redhat 4.2 for SPARC on a SPARC IPC. I have been
programming C and C++ for about four years now, but this problem has me
stumped. I am trying to port a few apps over from i386 linux to Sparc
linux. I downloaded the source files and untarred them just fine, but from
then on the horrors begin. I have read the docs for each app and followed
the instructions meticulously, and even tried some of my own homebrewed
fixes to try and get the sources to run, but I still can not get anywhere.
The problems seem to lie in not the source itself, but in the libs
installed on my machine. I get tons of warnings and one error that seems
to stand out. The error is transcribed as something like this:
<PRE>
/usr/include/time.h:58 -- Parse error for fd_func
</PRE>
<P> The only other problem I have found is on perusal of the *.h files, I have
found numerous references to header files in directories that don't EVEN
EXIST!!! Is this a standard thing, or just on the SPARC port for linux?
For example, I am looking inside my /usr/include/sys/time.h and find
references to a linux/time.h, when there is not a linux directory
anywhere!! Is this a standard? If it is, it seems that someone got a
little sloppy in their porting. I have managed to fix this problem by
going in and removing references to files that don't exist or redirecting
them to files that do exist, but the error above has definitely stumped me.
Does anyone have experience with this error and how it can be fixed? I
don't have much experience in building my own header files, but when I did
do it, I never saw that error. I would be much obliged to anyone who could
provide some guidence in this issue.

<BR>Subject: <FONT COLOR=navy>Help! Compatibility problems between linux and windows filesystems;</FONT>
StarOffice 5.1; Graphics settings
<P> Hi Linuxsters, I am a current Win98 user trying to switch to Linux, but
I have run into a few little problems!
<P> Firstly, after successfully partitioning my HDD and installing Red Hat
Linux 5.2, I wanted to reinstall Win98 as it was getting rather slow.
So I mounted my (FAT32) C: drive in Linux (mount -t vfat /dev/hda1
/mnt/c:) and backed up my essential files onto the Linux partition.
<P> After reinstalling Windows I copied the files back, only to discover
that some seemed to be corrupted by the Linux filesystem. Some
self-extracting programs like WinZip 7.0 and WinBoost 1.24 will not
execute, giving errors like "Permission denied" or "This is not a Win32
application". This is not a drama as I can simply download these again,
however many of my important compressed "zip" files containing Word
documents are corrupt and some files cannot be extracted. What is the
sitch? Can these files be "fixed"? Should I completely avoid mixing
the two filesystems in future? Any help would be gratefully
appreciated!
<P> Another problem I had was installing StarOffice 5.1 Personal Edition for
Linux - it freezes on page 2 of setup where it asks for the registration
key number. I downloaded the program from download.com and therefore
don't have a number. Even if I did it would be no use as the program
freezes anyway. Also I have since realised that it is probably because
I only have 15MB RAM (1MB for built-in video card) and not the minimum
requirement of 32MB (duh!). Which poses the question, "Why does MS
Office happily run on my system with the flaw-ridden inefficient Windows
OS, while StarOffice won't?" Please excuse me, I am only new to Linux!
I plan to upgrade my RAM soon so hopefully this won't be a problem -
just curious, you know?
<P> I am also having problems getting the appropriate graphics settings
happening on Linux. I have a Socket 7 M571 motherboard with a built-in
64-bit VGA chip. It is a 1 to 4MB chip and I have set it to 1MB (in
BIOS) due to my pathetic RAM situation. In Windows I can easily go to
800x600 and 1024x768 with 16- and 24-bit colour. During Red Hat Linux
5.2 installation I selected "VGA16" video card and "Custom:
Non-interlaced SVGA; 800x600@60Hz, 640x480@72Hz" monitor type. But it
won't go above 640x480 resolution without going into virtual mode. The
colour settings are also not right. What do I do?
<P> And finally (!) every time I exit "X", I get an error message "FreeFont
count is 2; should be 1; Fixing..." What does this mean and how do I fix
it? (do I need to?)
<P> I love the idea of leaving Windows behind but I can't while I have these
problems! Could I ask that any responses be reasonably basic as I am
totally new to Linux (or should I say "Linux is totally new to me!").
All help will be greatly appreciated! Thank you...
<P> Zubin.

<P> I was just reading the article "Setting up mail for a home network using

file any mail that contains Emily in the To header will go to emi's mailbox, if
someone was to send a message with several addresses in the To field one to
jbloggs and one address had Emily in it (weather Emily be the Emily on the
local network or some other Emily). If a person sent mail with only one To
address and bcc'd or cc'd the rest that problem wouldn't exist but alas not all
email is sent that way (at least to me). You could probably cut down on the
possibility of this a bit by having it look for Emily's first and last name.

<BR>Subject: <FONT COLOR=navy>LG Issue 42 - email article</FONT>
<P> I was most impressed with the following article in Linux Gazette 42,
June 1999: "Setting up mail for a home network using exim"
<P> I followed Jan's suggestions on a RedHat 5.1 Linux system and it
eventually worked. You may care to note the following comments and
pass them on to the author (as no email address was offered).
<OL>
<LI> The "exim" package as supplied with RedHat Linux does not include
"eximconfig". I pinched a copy from a Debian distribution using ar and tar. The
configure file is too hard to setup without it.
<LI> The perl script "outfilt" as published, fails on my system. The
'@' character in the script should be '\@'.
<LI> As I do not use a Smarthost for email, I found that taking out the
reference to it in the ROUTERS CONFIGURATION section of the exim configure
file, worked fine. (Note that Debian uses exim.conf whereas the RedHat version
of exim uses the file 'configure').
</OL>
<P> I have seen many requests for interfacing MS Internet Mail (???) to
Linux mail facilities on the Linux User Group discussion lists and
this article is most timely.

<P> A federal judge has indicated that he may rule in favor of <STRONG>Sun
Microsystems</STRONG> in the company's <STRONG>copyright battle with Microsoft
</STRONG>, allowing Sun to keep control of its Java programming language. The
ongoing legal battle between Sun and Microsoft arose from concerns that
Microsoft violated its licensing agreement with Sun for use of Java's source
code by altering Java to run more effectively on the Windows operating system.
U.S. District Judge Ronald Whyte wrote that he will most likely rule in favor
of Sun, preventing Microsoft and other companies from changing Java to run
certain software products better than others. Some analysts speculate that the
court loss may not deter Microsoft, but will instead provide the company with
incentive to stop using Java or even to develop an alternative. (Los Angeles
Times 05/26/99)
<P> <STRONG>IBM plans to adjust its AIX operating system to support Linux
applications.</STRONG> This will allow IBM customers to store all of their Web
applications on one server, the company says. IBM's Robert LeBlanc says, "As
more customers move to the Web, they'll need to integrate applications."
Enabling AIX to run Linux will help customers simplify and manage growing
networks, says LeBlanc. IBM's modified version of AIX will be released by the
end of this year, the company says. Analysts say IBM and Sun, which modified
Solaris to support Linux, are ensuring that they will be able to take advantage
of any Linux Web applications that may become popular in the future. In
addition to the AIX changes, IBM plans to ship its DB2 software with Pacific
HiTech's TurboLinux version of Linux. Pacific HiTech will package IBM's
WebSphere software with TurboLinux by the end of 1999, says IBM's Dick
Sullivan. (Bloomberg 05/25/99)

UseNetServer.Com allowing Linux users free access to their NNTP servers
</font>
</H3>
<P> UseNetServer.Com has made the decision to convert our NNTP systems to Linux
from MS Windows NT. In doing this we are opening up our servers to the Linux
Community for propagation of important information. UseNetServer.Com is
allowing all users interested in Linux newsgroup issues free access to our
servers. Your login / password is linux / free connecting to
Linux-news.usenetserver.com (207.153.76.21) or news2.usenetserver.com
(207.153.76.19).
<P> We have found several major bugs in the kernel which Alan Cox and Stephen
Tweedie have quickly resolved for us. Allowing commercial grade news to the
Linux community will speed the dissemination of Linux patches and problems. If
you have any new news groups you would like added to the hierarchy drop me an
email at usenet@exectech.net and we will include them. Joe Devita, and his
crew of propeller heads at the Linux General Store
(http://www.linuxgeneralstore.com) in Atlanta helped install and solve all of
our problems. Please note we are still working Rob Fleischmann with BCandid
(Highwind Software) to resolve some of their software issues with Linux.
<P> UseNetServer is peering with all the major NNTP providers to include
SuperNew, UUNet, SprintNet, and many other smaller providers. This provides a
near real time feed of this information, so you don't have to wait on your slow
local server for the data. I have added 70gb dedicated to just the Linux
groups, this will spool up to a ton of information for you. If you are
overseas, you can still connect to our servers as we are very well connected
via NetRail a tier-1 internet provider. We have terrific speed to the UK and
Asia which multiple DS-3s connected to MAE-East and MAE-West. Check us out.
http://www.usenetserver.com, we're a small company trying to help out a big

<P> Ottawa, Canada -- June 9, 1999 -- <STRONG>Corel</STRONG> Corporation is
pleased to announce that it is joining forces with
<STRONG>Channelware</STRONG>, a business unit of Nortel Networks to rent its
award-winning software applications to customers. This initiative joins the
first program involving distribution of Channelware's NetActive software
through retail stores.
<P> Corel Print House Magic 4 NetActive Version will be available for
customers to rent at select Blockbuster locations in Austin, Texas, and
Anchorage, Alaska, starting in June.
"Channelware invented secure Software Activation and we are proud to be
teaming up with them in this breakthrough initiative," said Dr. Michael
Cowpland, president and chief executive officer of Corel Corporation. "The
dynamics of the computer world are changing rapidly, and we are keen to use
this rental technology to allow our customers to access our products more
easily - even without leaving their houses. This is an innovation in the
software industry."
<P> Channelware's NetActive technology will be embedded in the Corel software,
making it possible for customers to rent the software for 72 hours. Once
the customer brings the CD-ROM home and launches the application, the
software will connect to the Channelware Activation Server. A one-time
InstanceKey is then delivered over the Web in seconds. The key enables the
customer to start using the software. The NetActive system keeps track of
how long the customer uses the software, and offers the customer options
for extended use.
<P> Unlike standard video rentals, the customer will keep the software rental
CD after the initial rental is over. After the rental period, the user has
the option to: rent the software again; buy the right to use the rented
software on a perpetual basis; or buy retail versions of Corel Print House
Magic online and have the shrinkwrap versions of the product delivered to
the door. The 72-hour rental has a suggested retail price (SRP) of US
$5.99; re-renting costs US $3.99. Customers can buy Corel Print House Magic
4 NetActive Version on a perpetual basis for US $29.95*.

Benchmark specialist invites Red Hat and Microsoft to a rematch
</font>
</H3>
<P> Chicago, IL -(June 17 1999) - Neal Nelson, benchmark guru and founder of
the world's largest independent client/server testing facility, has extended an
invitation to Microsoft and Red Hat to participate in an open, public
performance comparison between hot operating system rivals Windows NT and
Linux.
<P> Nelson issued the invitation as a result of a recently published study
sponsored by Microsoft.* One of the conclusions of the study is that
"Microsoft Windows NT Server 4.0 is 2.5 times faster than Linux as a File
Server and 3.7 times faster as a Web Server."
<P> Many have questioned the test results because different tuning levels were
used for NT than those used with Linux. For example, NT was tested with NT
tuning, benchmarking and technical support from Microsoft, as well as
Internet Information Server 4.0 tuning information from the Standard
Performance Evaluation Corp.
<P> Linux however, received almost no additional tuning, support or involvement
from Linux-based technical sources. The testing lab cited difficulty in
obtaining tuning information from Linux knowledge bases, and a query with
Red Hat ended up going through the wrong channels.
<P> This has outraged the growing base of Linux supporters who are clamoring for
an unbiased test, one that is not sponsored by either Microsoft or Linux.

>Greetings from Jim Dennis</H3>
<!-- begin greeting -->
<p>So, my LG activity for this month is pretty sparse. Does
that mean that I haven't been involved in any Linux activity?
Does it mean that I'm not getting enough LG TAG e-mail?
</p><blockquote>
HARDLY!
</blockquote><p>
However, my work at <a href="http://www.linuxcare.com/">Linuxcare</a>
has been taking a pretty big bite
out of my time. In addition the long drive up to the city
(from my house in Campbell to Linuxcare's offices in San Francisco
is about 50 miles) keeps me away from the keyboard for far too
long. (Yes, I'm looking for <em>cheap</em> digs up in the city to keep
my up there during the week).
</p><p>
Mostly I've been working with our training department, presenting
classes on Linux Systems Administration to our customers and our
new employees, and helping develop and refine the courseware around
which the classes are built.
</p><p>
I've also been watching the Linux news on the 'net with my usual
zeal.
</p><p>
The leading story this month seems to be
"<a href="http://www.mindcraft.com/whitepapers/openbench1.html"
>Mindcraft III</a> --- The Return of the Benchmarkers."
The results of the benchmarking tests aren't surprising. NT
with IIS still fared better on this particular platform under
<a href="http://www.kegel.com/mindcraft_redux.html">these test conditions</a>
than the Linux+Apache+Samba combination. The Linux 2.2.9 kernel and
The Apache 1.3.6 release seems to have closed almost half of the gap.
</p><p>
As I suggested last month, the most interesting lessons from this
story have little to do with the programming and the numeric
results. There were technical issues in the 2.2.5 kernel that
were addressed by 2.2.9. I guess Apache was updated to use the
<tt>sendfile()</tt> system call. These are relatively minor tweaks.
</p><p>
Microsoft and Mindcraft collaborated for a significant amount
of time to find a set of conditions under which the Linux/Apache/
Samba combination would perform at a disadvantage to NT.
</p><p>
When MS and Mindcraft originally published their results the
suite of tests and the processes employeed were thoroughly
and quickly discredited. I've never seen such in-depth
analysis about the value (or lack thereof) of benchmarking in
the computing industry press.
</p><p>
Nonetheless, the developers of the involved open source packages
shrugged, analyzed the results, did some profiling of their own,
looked over their respective bits of code, devoted hours to
coding tweaks, a few days worth to tests, and spent some time
exchanging and debating different approaches to improving the code.
</p><p>
The important lessons from this are:
</p><ol>
<li> Just because a criticism is discredited, biased, and
possibly dishonest doesn't mean that we can't find
some clues to lead to real improvements. These
developers could have stuck their heads in the sand and
dismissed the whole topic as unimportant. They could
have felt that the PR and advocacy responses would
suffice.
<br>&nbsp;<br>
That "ostrich" approach is more commonly found in
corporate and government circles than among freeware
programmers. This is largely due to management. A
development manager at a large corporation will tend
to put as much energy into internal PR and "spin
control" as to any real improvement in the product.
Programmers often find themselves at odds with
their own management.
<br>&nbsp;<br>
<li> When we choose to attend to criticisms, it's vital
not to adopt their demonstration model as your objective.
We must stay true to our own requirements.
<br>&nbsp;<br>
It would be easy to focus on "beating the Mindcraft
benchmark" --- to insert special case code that exists
solely to produce superior results under the specific
conditions present in that suite of tests.
<br>&nbsp;<br>
This is referred to as "fraud."
<br>&nbsp;<br>
It would be technically easy for the kernel developers
to write the code for this. However, it would be
difficult to actually perpetrate this or any other fraud
in any open source project (since the code is there for
all to see --- and there are a number of people who
actually read that code).
<br>&nbsp;<br>
So, the Linux, Apache, and Samba developers showed
admirable focus on real improvements and seemed to
have eschewed any temptation to commit fraud.
<br>&nbsp;<br>
(We can't know whether the competition has rigged their
platform, since it is closed source and hasn't been
thoroughly audited by reputable independents).
</ol><p>
This leads us to a broader lesson. We can't properly evaluate any
statistics (benchmark results are statistics, after all) without
considering the source. What were the objectives (the
requirements) of the people involved? Are the objectives of the
people who took the measurements compatible with those of their
audience. In large part any statistic "means" what the presenter
intends it to "mean" (i.e. the number can only be applied to the
situation that was measured).
</p><p>
Benchmarks are employed primarily by two groups of people:
Software and hardware company marketeers, and computer periodical
writers, editors and publishers. Occasionally sysadmins and IT
people use statistics that are similar to benchmarks ---
simulations results --- for their performance tuning and
capacity planning work. Unfortunately these simulations are
often confused with benchmarks.
</p><ul>
<li> Interestingly the term benchmark probably stems from
physical "marks" (scratches or grooves), in work benches
used by woodworkers and other craftsmen to provide handy
measurements for their productions.
</ul><p>
Jim's first rule of requirements analysis is:
</p><blockquote>
Identify the involved parties.
</blockquote><p>
In this case we see two different producers of benchmarks and
a common audience (the potential customers, and the readership
are mostly the same). We also see that the real customers of
most periodicals are the advertisers --- which work for the same
corporations as the marketeers. This leads to a preference for
benchmarks that is bred of familiarity.
</p><p>
Most real people on the street don't "use" benchmarks. They may
be affected by them (as the opinions they form and get form others
are partially swayed by overall reputations of the organizations
that produce the benchmarks and those of the publications they read).
</p><p>
One of the best <a href="http://cs.alfred.edu/~lansdoct/mstest.html"
>responses</a> to the Mindcraft III results that I've
read is by Christopher Lansdown. Basically it turns the question around.
</p><p>
Instead of interpreting the top of the graphs as "how fast does
this go?" (a performance question) he looks at the bottom and the
"baseline" system configurations (intended for comparison) and
asks: "What is the most cost effective hardware and software
combination which will provide the optimal capacity?"
</p><p>
This is an objective which matches that of most IT directors,
sysadmins, webmasters and other people in the real world.
</p><p>
Let's consider the hypothetical question: Which is faster, an
ostrich or a penguin? Which is faster UNDERWATER?
</p><p>
What Christopher points out is that a single processor PC
with a couple hundred Mb of RAM and a single fast ethernet
card is adequate for serving simple, static HTML pages to
the web for any organization that has less than about 5 or
6 T1 (high speed) Internet lines. That is regardless of
the demand/load (millions of hits per day) since the webserver
will be idly waiting for the communications channels to clear
whenever the demand exceeds the channel capacity.
</p><p>
The Mindcraft benchmarks clearly demonstrate this fact.
You don't need NT with IIS and a 4 CPU SMP system with a
Gigabyte of RAM and four 100Mbps ethernet cards to provide
web services to the Internet. These results also suggest
rather strongly that you don't need that platform for
serving static HTML to your high speed Intranet.
</p><p>
Of course, the immediate retort is to question the applicability
of these results to <em>dynamic content</em>. The Mindcraft benchmark
design doesn't measure any form of dynamic content (but the
<a href="http://www.heise.de/ct/english//99/13/186-1/">c't magazine</a>
did - their article also has performance tuning hints for high-end hardware).
Given the obvious objectives of the designers of this benchmark
suite we can speculate that NT wouldn't fare as well in that scenario.
Other empirical and anecdotal evidence supports that hypothesis; most
users who have experience with Linux and NT webservers claim that
the Linux systems "seem" more responsive and more robust;
Microsoft uses about a half dozen separate NT webservers at their
site (which still "feels" slow to many users).
</p><p>
This brings us back to our key lesson. Selection of hardware and
software platforms should be based on requirements analysis.
Benchmarks serve the requirements of the people who produce and
disseminate them. Those requirements are unlikely to match those
of the people who will be ultimately selecting software and
hardware for real world deployment.
</p><p>
It is interesting to ask: "How does NT gain an advantage in this
situation?" and "What could Linux do to perform better under those
circumstances?"
</p><p>
From what I've read there are a few tricks that might help.
Apparently one of the issues in this scenario is the fact that
the system tested as four high speed ethernet cards.
</p><p>
Normally Linux (and other operating systems) are
"interrupt-driven" --- activity on an interface generates an
"interrupt" (a hardware event) which triggers some software
activity (to schedule a handler). This is normally a
efficient model. Most devices (network interfaces, hard disk
controllers, serial ports, keyboards, etc) only need to be
"serviced" occasionally (at rates that are glacial by
comparison to modern processors).
</p><p>
Apparently NT has some sort of option to disable interrupts on (at
least some) interfaces.
</p><p>
The other common model for handling I/O is called "polling." In
this case the CPU checks for new data as frequently as its
processing load allows. Polling is incredibly inefficient under
most circumstances.
</p><p>
However, under the conditions present in the Mindcraft survey
it can be more efficient and offer less latency than interrupt
driven techniques.
</p><p>
It would be sheer idiocy for Linux to adopt a straight polling
strategy for it's networking interfaces. However, it might be
possible to have a hybrid. If the interrupt frequency on a
given device exceeds one threshold the kernel might then switch
to polling on that device. When the polling shows that the
activity on that device as dropped back below another threshold it
might be able to switch back to interrupt-driven mode.
</p><p>
I don't know if this is feasible. I don't even know if it's
being considered by any Linux kernel developers. It might
involve some significant retooling of each of the ethernet
drivers. But, it is an interesting question. Other interesting
questions: Will this be of benefit to any significant number of
real world applications? Do those benefits outweigh the costs
of implementation (larger more complex kernels, more opportunities
for bugs, etc)?
</p><p>
Another obvious criticism of the whole Mindcraft scenario is the
use of Apache. The Apache team's priorities relate to correctness
(conformance to published standards), portability (the Apache
web server and related tools run on almost all forms of UNIX, not
just Linux; they even run on NT and its ilk), and features
(support for the many modules and forms of dynamic content, etc).
Note that performance isn't in the top three on this list.
</p><p>
Apache isn't the only web server available for Linux. It also
isn't the "vendor preferred" web server (whatever that would
mean!) So the primary justification for using it in these
benchmarks is that it is the dominant web server in the Linux
market. In fact Apache is the dominant web server on the Internet
as a whole. Over half of all publicly accessible web servers
run Apache or some derivative. (We might be tempted to draw a
conclusion from this. It might be that some features are more
important to more web masters than sheer performance speeds and
latencies. Of course that might be an erroneous conclusion ---
the dominance of Apache could be due to other factors. The
dominance of MS Windows is primarily and artifact of the PC
purchasing process --- MS Windows comes pre-installed, as did
MS-DOS before it).
</p><p>
So, what if we switch out Apache for some other web server.
</p><p>
Zeus (<a href="http://www.zeustech.net/products/zeus3/"
>http://www.zeustech.net/products/zeus3/</a>), a commercial
offering for Linux and other forms of UNIX, is probably the
fastest in existence.
</p><p>
thttpd (<a href="http://www.acme.com/software/thttpd/"
>http://www.acme.com/software/thttpd/</a>) is probably the
fastest in the "free" world. It's about as fast as the
experimental <a href="http://www.fenrus.demon.nl/">kHTTPd</a>
(an implementation of a web server that
runs directly in the kernel -- like the kNFSd that's available
for Linux 2.2.x).
</p><p>
Under many conditions thttpd (and probably kHTTPd) are a few
times faster than Apache. So they might beat NT + IIS by
about 100 to 200 per cent. Of course, performance analysis is
not that simple. If the kernel really is tied up in interrupt
processing for a major portion of it's time in the Mindcraft
scenario --- then the fast lightweight web server might offer
only marginal improvement FOR THAT TEST.
</p><p>
For us back in the real world the implication is clear, however.
If all you want to do is serve static pages with as little load
and delay as possible --- consider using a lightweight httpd.
</p><p>
Also back in the real world we get back to other questions.
How much does the hardware for a Mindcraft configuration cost?
How much would it cost for a normal corporation to
purchase/license the NT+IIS configuration that would be required
for that configuration? (If I recall correctly, Microsoft still
charges user licensing fees based on the desired capacity of
concurrent IIS processes/threads/connections. I don't know the
details, but I get the impression that you'd have to add a few
grand to the $900 copy of NT server to legally support a
"Mindcraft" configuration).
</p><p>
It's likely that a different test --- one whose objectives were
stated to more closely simulate a "real world" market might
give much different results.
</p><p>
Consider this:
</p><blockquote>
<strong>Objective:</strong> Build/configure a web service out of standard
commercially/freely available hardware and software components
such that the total cost of the installation/deployment would be
cost a typical customer less than $3000 outlay and no more than
$1000 per year of recurring expenses (not counting bandwidth and
ISP charges).
</blockquote><blockquote>
Participants will be free to bring any software and hardware that
conforms to these requirements and to perform any tuning or
optimizations they wish before and between scheduled executions
of the test suite.
</blockquote><blockquote>
<strong>Results:</strong> The competing configurations will be tested with a
mixture various sorts of common requests. The required responses
will include static and dynamic pages which will be checked for
correctness against a published baseline. Configurations
generating more than X errors will be disqualified. Response
times will be measured and graphed over a range of simulated
loads. Any service failures will be noted on the graph where they
occur. The graphs for each configuration will be computed based
on the averages over Y runs through the test suite.
</blockquote><blockquote>
The graphs will be published as the final results.
</blockquote><p>
The whole test could be redone for $5000 and $10000 price points
to give an overview of the scalability of each configuration.
</p><p>
Note that this proposed benchmark idea (it's not a complete
specification) doesn't generate a simple number. The graphs of
the entire performance are the result. This allows the potential
customer to gauge the configurations against their anticipated
requirements.
</p><p>
How would a team of Linux/Apache and Samba enthusiasts approach
this sort of contest? I'll save that question for next month.
</p><p>
Meanwhile, if you're enough of a glutton for my writing (an
odd form of PUNishment I'll admit) and my paltry selection of
answers, rants and ramblings for this month isn't enough then
take a look at a couple of my "Open Letters"
(<a href="http://www.starshine.org/jimd/openletters"
>http://www.starshine.org/jimd/openletters</a>).
By next month I hope
that my book (<a href="http://www.newriders.com/934-3.htm">Linux Systems
Administration</a>) will be off to the printers and my work at
Linuxcare will have reached a level where I can do MORE ANSWER GUY QUESTIONS!

data. One copy is named <TT>.../$OLDDIR.old</TT> and the other
is a new filesystem mounted on <TT>.../$OLDDIR</TT>
</BLOCKQUOTE>
<BLOCKQUOTE>
After you've verified, to your satisfaction, that
everything is alright after your change, you can remove
the old copy with '<tt>rm -fr $OLDDIR.old</tt>'
</BLOCKQUOTE>
<BLOCKQUOTE>
In general there are two ways to transparently migrate
data from one filesystem to another under UNIX.
</BLOCKQUOTE>
<BLOCKQUOTE>
The method I've describe moves the data onto a new
filesystem that's mounted directly under the old
location. Another method is to create a new filesystem
on an arbitrary mount point (conventionally <TT>/u1</TT>, <TT>/u2</TT>, etc).
and the original directory is replaced with a symlink to
point to a directory under that new fs.
</BLOCKQUOTE>
<BLOCKQUOTE>
In either case it's possible that some differences will
not be entirely transparent. In particular some files
might have had hardlinks that crossed the boundary of the
directory tree. Those links would now be broken (resulting
in two separate files where formerly you had one file
with two or more links. This is rarely a problem. However
you could test for this case with a bit of scripting and editing.
</BLOCKQUOTE>
<BLOCKQUOTE>
Mainly you generate a report using '<tt>find</tt>'. Use something like:
</BLOCKQUOTE>
<blockquote><pre>find $FSROOT -xdev -not -type d -links +1 \
-printf "%i %p\n" | sort -n
</pre></blockquote>
<BLOCKQUOTE>
... where <tt>$FSROOT</tt> is the root of whichever filesystem
houses the directory tree that you're trying to migrate.
</BLOCKQUOTE>
<BLOCKQUOTE>
This prints a list of files sorted by their inodes. Any set
of hard links to a given file have their device number and
inode pair in common. You can then manually seach the
resulting list (usually fairly short). For any even file
you don't have to worry at all if all of its links, or none
of its links, are under the subdirectory tree that you are
moving. Probably there will be none that have this problem.
For those that do, simply replace one set of the hard links
with symlinks. In other words, all of the hard links that
are inside the target directory tree should be converted to
symlinks, or vice versa.
</BLOCKQUOTE>
<BLOCKQUOTE>
It's very unlikely that this will cause any problem. If you
ever see a case where a UNIX or Linux program suffers from
"transplant shock" I'd like to hear about it.

Would the terminal program start the null modem connection or
would you have to have it be connected before hand through DOS
(I don't know a whole lot about DOS)? I know Linux will be
looking for a terminal on <tt>ttyS0</tt> but will a terminal emulator
show up as a terminal connected on that port?

Linux will look for terminal connections on
a line (<TT>/dev/ttyS0</TT>, <TT>/dev/ttyS1</TT>, whatever) if it
it has a "<tt>getty</tt>" process running on that port.
</BLOCKQUOTE>
<BLOCKQUOTE>
You set up a getty process by modifying your <TT>/etc/inittab</TT>
and adding a line like:
</BLOCKQUOTE>
<blockquote><pre>d1:23:respawn:/sbin/agetty -L 38400,19200,9600,2400,1200 ttyS1 vt100

... where you can use <tt>agetty</tt>, <tt>uugetty</tt>, <tt>mgetty</tt>, or
<tt>getty_ps</tt> (but not <tt>mingetty</tt>). The syntax and additional
configuration of each of these other getty packages differs slightly.

As far as the DOS side of this, you generally just have to

Thanks you for your detailed reply. Since I wrote, I resolved
(although not yet solved) the problem. I had a free partition on
my disk, which I made bootable, and installed (from scratch) the
new RedHat 5.2. This came up with no real problems. Then I began
moving some of the stuff from the old partition to the
new. Everything works. When things settle down, and I've got
everything from the old slice that I need, I will just wipe it
out, and free it up.

Glad you got it working.
If you have the disk space (on a second drive or extra
partition) you could do a fresh installation of
<A HREF="http://www.redhat.com/">Red Hat</A> 6.0 and then selectively
migrate your configuration and data files from your old filesystems.
It's sort of a slow laborious way to do upgrades, but it's one that works
for me.

Hi.
</STRONG></P>
<P><STRONG>
I came across this page where someone'd asked you a question,
apparently identical to something a (non-techie) friend of mine is
now experiencing, except that his Linux is a vanilla RedHat 5.1
install (although with Star Office, and RedHat 5.2 Ghostscript and
ppp).
</STRONG></P>
<P><STRONG>
He has a PCI PnP soundcard in his machine, which he's not managed
to get working with W95 or with Linux, but the rest of the machine
worked fine for both OSs, including the floppy.
</STRONG></P>
<P><STRONG>
All of a sudden, about a month ago, the floppy stopped mounting on
Linux (works fine on W95).

When I try `<TT>mount -t msdos /dev/fd0 /tmp/floppy</TT>', the mount

it can't write to the device.

If you're interested in whether fiddling with the soundcard fixes
the problem, I'll be happy to let you know, but since mcopy and
mdir work, this seems unlikely.
</STRONG></P>
<P><STRONG>
Nothing's been added or removed within the machine's case, so I
think the only thing that could have changed, which persists over
powerdowns, is the CMOS, and hence (presumably) some aspect of PnP

What happens if you try mounting it in read-only mode?
</BLOCKQUOTE>
<BLOCKQUOTE>
It sure sounds like a hardware failure. I'd buy an
extra floppy drive (about $20 US in most computer parts
stores). I've asked questions to see if the problem
is limited to the write functionality (since a careful
reading of your messages seems to correlate to read-only
vs. read/write access). When you mount a filesystem
in rw mode under Linux --- I think the atime on the
root of that filesystem will be updated (involving
a write to the media). If it works when you try the
'<tt>mount -o ro</tt>' variation on the command --- that
suggests that it is related to the write functions.

Hi Jim.
</strong></p>
<p><strong>
Ach! Rats!
</strong></p>
<p><strong>
I forgot to email you the solution I discovered!
</strong></p>
<p><strong>
The drive wrote perfectly well under Windows, and worked without difficulty in
both directions with <tt>mcopy</tt>. I should have made this clearer in my
first email; my apologies for this.
</strong></p>
<p><strong>
The functionality of the drive, and the evident integrity of the msdos filing
system module eliminated those subsystems from the problem, which was why I was
so perplexed, and why I wrote to you.

</strong></p>
<p><strong>
The next day, I used <tt>strace</tt> on `<tt>mount</tt>' to try and find out
where it hung. It hung on the actual <tt>mount()</tt> system call itself.
</strong></p>
<p><strong>
I noticed that the automounter was in `<tt>D</tt>' discwait on the process
list during its own mount attempt, so I disabled it in the boot sequence
while trying to find out what was going on (I wanted to strace the very
first attempt to mount the floppydrive) but that cured the problem!

<p><strong>
Further investigation (with <tt>strace</tt>) revealed that I'd earlier changed
<TT>/etc/resolv.conf</TT> to include a domain search path while trying to set
my friend up with an ISP account, and the DNS hang was causing automount to
hang while trying to finagle those strange pseudo-NFS mounts of the local
host it does (by the host's internet name, not as `localhost') for the floppy
drive!
</strong></p>
<p><strong>
I fixed <tt>resolv.conf</tt>, and the problem went away, although I've left
AMD disabled, because autofs does the same job, and was installed alongside
it on RedHat; and because one day I'll get my friend's ISP working on Linux
as well as Windows. I don't want this to repeat.

Of course, if you used Linux it would be pretty easy to
secure the system so that the Internet and the modem were
inaccessible during specific times of day or until specific
passwords had been typed. It would even be possible to
configure filtering and access control (to monitor and limit
web access). You'd probably need to invest in some
cabinetry (physically securing a PC generally involves carpentry).
</BLOCKQUOTE>
<BLOCKQUOTE>
Your question has nothing to do with Linux.
</BLOCKQUOTE>
<BLOCKQUOTE>
More importantly your problem is much larger than any
software can solve. No software in the world could possibly
make your son more trustworthy. You cannot keep your kid
out of "big trouble on the net" by spying on his keystrokes.
</BLOCKQUOTE>
<BLOCKQUOTE>
If the muddled thinking that leads you to the fundamentally
flawed (and morally corrupt) notion that you should covertly
spy on your own teenage child using such software is typical
of your approach to parenting then its probably too late for
Bernie Jr.
</BLOCKQUOTE>
<BLOCKQUOTE>
I don't know what kind of "big trouble" you're trying to
protect the kid from. If it's porn, keep in mind that porn
sites are generally accessed through a GUI browser --- which
are conveniently configured for one-handed operation (point
and shoot, so to speak). If you're afraid that the kid is
"cracking" (sometimes erroneously referred to as "hacking")
and/or phreaking than any attempts you make to lock him out
of your Windows '98 PC will just be too pathetic. If you do
successfully find out that he's been vising 'badboys.net'
what do you plan to do? Confront him with your printouts?
Ground him until he's 35?
</BLOCKQUOTE>
<BLOCKQUOTE>
So what do you think the kid will do when he knows he's been
caught out? Will it be an contest: your computer skills and
time against his? Can he detect and bypass your futre
methods better than you can implement them? Will he go use
some buddy's computer? Will he skip the virtual trouble of
the 'net and go out to get into trouble of a more dangerous
variety? What will it do for the kid's opinion of you that
you don't have the balls to talk to him directly and that
you have to resort sneaking around on him?
</BLOCKQUOTE>
<BLOCKQUOTE>
The whole think is disgusting.
</BLOCKQUOTE>
<BLOCKQUOTE>
If you can't trust the kid with the computer by himself ---
lock the computer is some room when you're not home or get
rid of it.

It could be some incompatibility between the slave and
master (some IDE drives cannot co-exist in some combinations
on an IDE channel). Try running it on the other IDE channel
that you'll find in most recent PCs. (Configure the new
drive as standalone or as the master to your IDE/ATAPI

You might also try using some punctuation and capitalization

you can give the impression that you've done a bit of

own.
</BLOCKQUOTE>

Naturally you could also try installing Linux on this drive.
Linux has a neat utility called 'badblocks' which can be
used by itself and which is called by our filesystem
creation and filesystem check utilities (mke2fs and e2fsck
among others). After all, I'm the LINUX GAZETTE "Answer Guy"

I was copying a new slackware 4.0 installation from one disk to another.

You might not have preserved allocation "holes" (the
"sparsity") of the files as you transferred them.
</BLOCKQUOTE>
<BLOCKQUOTE>
When a program opens a file in write mode and does a <tt>seek()</tt>
or <tt>lseek()</tt> to some point that is more than a block past the
end of the file, the Linux native filesystems (<tt>ext2</tt>, <tt>minix</tt>,
etc) will leave the unnecessary blocks unallocated. This
is possible in inode based filesystems (not in FAT/MS-DOS
formatted filesystems).
</BLOCKQUOTE>
<BLOCKQUOTE>
These filesystems treat reads into such unallocated regions
of a file as blocks of NULs (ASCII zero characters).
</BLOCKQUOTE>
<BLOCKQUOTE>
So, you use normal read and write commands in sequence
(like '<tt>cp</tt>' and '<tt>cat</tt>' to to copy files) then you'll expand
any such "holes" in the allocation map (the inode's list
of clusters) into blocks of NULs and the file will
take more space than it used to.
</BLOCKQUOTE>
<BLOCKQUOTE>
One possibility is that you used to have such "sparse"
files and that your method of copying them failed to
preserve those "holes." You could use the GNU '<tt>cp
--sparse=always</tt>' option to restore the "holes" in
selected files (or create new ones wherever there are
blocks of NULs in the data).
</BLOCKQUOTE>
<BLOCKQUOTE>
Most files are not sparse --- in fact there are only a
couple of old dbm style libraries that used to create
them in normal system use (the sendmail <tt>newaliases</tt>
command used to be a prime example).
</BLOCKQUOTE>
<BLOCKQUOTE>
I don't think this accounts for your whole problem (i.e.
it's not wholly a "holey" problem).
</BLOCKQUOTE>

Now, the problem is this: after the copy was complete, i used the
slackware bootdisk and rootdisk to reboot things nice and clean to test
the disk, and every copy i tried to do (including running lilo)
resulted in a "file too large" error message. A '<tt>df</tt>' reported that the
disk had lots of space on it, as did '<tt>du</tt>' (as did basic common sense
<IMG SRC="./../gx/dennis/smily.gif" ALT=":)"
height="24" width="20" align="middle"> ).
The disk became completely unusable until i destroyed it and reinstalled
slackware from scratch.
</STRONG></P>
<BLOCKQUOTE><IMG SRC="./../gx/dennis/bbub.gif" ALT="(!)"

Perhaps you should look at the output of the '<TT>df -i</TT>' command.
</BLOCKQUOTE>
<BLOCKQUOTE>
Your Linux filesystems actually have couple of resources that
are depleted at different rates from one another. If you
have lots of small files than you are using up inodes faster
than data blocks. The normal '<tt>df</tt>' command output reports
on your free <EM>data</EM> space. '<tt>df -i</tt>' reports on the
inode utilization.
</BLOCKQUOTE>
<BLOCKQUOTE>
So, its possible that you ran out of inodes even if you have
plenty of disk space.

Now, considering that the disk was just a 'raw' disk with data on it (ie.

It is very easy to accidentally copy/archive your <TT>/proc</TT>
(which is generally no harm). The problem is that you
can easily restore that to your new root fs and
mount a real <TT>/proc</TT> back over the restored <em>copy/snapshot</em>
of the state of your proc fs back when you did the backup.
</BLOCKQUOTE>
<BLOCKQUOTE>
I recommend that you use the <tt>find -xdev</tt> or <tt>-mount</tt> options
to prevent your find from crossing filesystem boundaries.
</BLOCKQUOTE>
<BLOCKQUOTE>
Let's say you have <TT>/</TT>, <TT>/usr/</TT>, <TT>/var</TT>,
<TT>/usr/local</TT>, and <TT>/home</TT> as local filesystems. To use
'<tt>cpio</tt>' to back them up you could use a command like
</BLOCKQUOTE>
<BLOCKQUOTE><BLOCKQUOTE><CODE>
find / /usr/ /var /usr/local /home -mount -depth | cpio ....
</CODE></BLOCKQUOTE></BLOCKQUOTE>
<BLOCKQUOTE>
... to feed only the file names that are on that list
of filesystem to <tt>cpio</tt>.
</BLOCKQUOTE>
<BLOCKQUOTE>
When using '<tt>cpio</tt>' you can preserve sparsity while
COPYING IN your data using the <tt>--sparse</tt> option.
</BLOCKQUOTE>
<BLOCKQUOTE>
Of course '<tt>tar</tt>' works differently from '<tt>cpio</tt>' in just
about everyway that you could think of. You have to
use something a bit more like:
</BLOCKQUOTE>
<BLOCKQUOTE><BlockQuote><Code>
tar cSlf /dev/st0 / /usr/ /var /usr/local /home
</Code></BlockQuote></BLOCKQUOTE>
<BLOCKQUOTE>
... where the <tt>-S</tt> preserves sparsity (during archive
creation; and apparently NOT during restoration
unless the archive was correctly created). Personally
I think that this is a bug in GNU tar.
</BLOCKQUOTE>
<BLOCKQUOTE><em>[ I suppose fortcing someone to use -S (or --sparse)
when restoring offers the </em>ability<em> to desparsify the
file, on a new filesystem which has room for it. Why it
should be the default to not come out as it went in, though,
I've no idea. -- Heather ]
</em></BLOCKQUOTE>
<BLOCKQUOTE>
The <tt>tar -l</tt> option instructs '<tt>tar</tt>' not to cross fs boundaries.
</BLOCKQUOTE>
<BLOCKQUOTE>
The key general point here is that you might have
mounted <TT>/proc</TT> or any other filesystem over a non-empty
mount point. I personally think that the distribution
maintainers should modify the default <tt>rc*</tt> scripts
so that they won't mount filesystems over non-empty
directories. I'd modify them to uniquely rename and
remake any non-empty directory before mounting something
over it (and post a nastygram to syslog, of course).
</BLOCKQUOTE>
<BLOCKQUOTE><em>[ I disagree; I often touch a file named
<code>THIS_IS_THE_UNDERLYING_MOUNTPOINT</code> for mount points,
and I've actually had occasional administrative use for a few
files to sit in the underlying drive in case that fs doesn't
mount. Usually, notes about what should have been there,
although I suppose that could be the content of the
commentary filename above. -- Heather ]

I really don't know if I've given you the answer that will
help for your situation. I've just tried to explain the
most common couple of "out of space" situations that I've
seen and heard about --- with the hopes that you're
situation isn't more bizarre.
</BLOCKQUOTE>
<BLOCKQUOTE>
If your space problems persist through a reboot then
you don't have the old "open anonymous file" problem
(which I've described on other occasions). It's also a
very good idea to run <tt>fsck</tt> (do a filesystem check)
when you can't account for your missing space.

I was wondering if you have had any experience or know of anyone
using Arco's DupliDisk for mirroring IDE drives. Wanted to know something
about reliability, ease of installation, etc. Specifically, if a hard disk
must be cloned prior to linking to its mate, or if the card mirrors the
entire drive upon installation.

In any event I'm not sure that the ~$200 you'd spend on one
of these would really net you much advantage over Linux
built-in md (multi-device) drivers (which implement
striping, mirroring and RAID 5 through software).
</BLOCKQUOTE>
<BLOCKQUOTE>
These devices don't do give any performance advantage over a
single disk drive (mentioned in their FAQ). Even the Linux
software driver gives <EM>some</EM> performance edge over single
disk (by interleaving read and write requests among the
available drives and resynching the devices asynchronously
through its caching mechanisms).
</BLOCKQUOTE>
<BLOCKQUOTE>
You should also consider the nature of the risks which the
Duplidisk addresses vs. the actual risk profiles that are
present. Duplidisk only protects you from a single drive
failure (per controller). It doesn't address accidental
deletion, damage due to software bugs (data corruption, etc)
or deliberate sabotage due to failures in your security
measures (including crackers, trojans, viruses, etc).
</BLOCKQUOTE>
<BLOCKQUOTE>
Drive failure is currently one of the less common causes of
data losss under Linux (although the rate of damage caused
by PC virus infection are probably even lower than disk
failure under Linux).
</BLOCKQUOTE>
<BLOCKQUOTE>
Overall, I think you're much better served by
using an extra hard drive (which you'd connect to Duplidisk)
and just perform nightly snapshots to it using 'cp -pax'
and or 'cpio -p' or 'tar cf ...' piped into a 'tar xf ...'
The "snapshot" method protects against several different
threats --- particularly that of accidental deletion; which
is the most common cause of data loss. (If you have a
'cron' job which makes your snapshots in the middle of the
night you'll usually have a half a day or so to realize that
you've accidentally removed or damaged some of them).
</BLOCKQUOTE>
<BLOCKQUOTE>
Personally I think that's a better way of spending your
money. (Heck, you can use the extra two hundred bucks to
put in a third drive --- and use a combination of md/RAID-1
--- mirroring across a pair of drives and using the third
for snapshots).

Any external modem should work. Some internal modems
will --- but I don't recommend internal modems as a rule.
</BLOCKQUOTE>
<BLOCKQUOTE>
Unfortunately modems are one of those classes of PC
components where the specific models and brands change
so often that I just can't keep track of the "good ones."
</BLOCKQUOTE>
<BLOCKQUOTE>
I personally like Zyxel and Practical Peripherals.
I don't like the USR "Sportster" line (cheap) and find
that their "Courier" series is of high quality but
also inordinately high price for home applications.
(ISPs see very high duty cycles on their modems ---
the extra money spent on an industrial grade modem for
them is usually well spent; home and most office system
modems get only intermittent use and light duty cycles).

"." in root's path is unsafe!! (was: a.out binaries not working)
</font> </H3>
<BR>Date: Sat, 12 Jun 1999 14:58:28 -0400
<BR>From: "Peter V. Inskeep" <pinskeep@iglou.com>
<P> In Linux Gazette, Issue # 42, I provided an answer to the question of
getting an a.out binary to run. I suggested that typing "./a.out" (sans
quotes) would do the trick. I went on to suggest that the "current
directory" be added to the path to avoid the bother of typing ./ before
the name of the binary to be run.
<P> Several have written to me to point out that adding ./ to the path is
not good practice from a security viewpoint. Therefore, I urge anyone
who has added the ./ to their path after reading my answer, remove it.
Instead, just get in the practice of typing ./myprogramname when one
wants to run a binary in the current directory.
<P> I'd like to take this opportunity to thank Alex B., Art W., and
Pete in the UK for taking the time to write me notes explaining the
pitfalls of putting dot slash (./) in one's PATH. This is especially
true for root, but apparently not good practice for anyone. As I
understand it, a transgressor could easily put a program with evil
intentions, but with a common name, such as "ls," in one of your
commonly used directories. Next time you type ls on the command line,
the evil program is run rather than the ls directory display program.
This is so if one had modified one's PATH to include ./. If one had to
include ./ in one's path, make sure it is at the end of the PATH
statement.
<P> Thanks for giving me this opportunity to correct the bad information I
presented. Also, thanks again to those who took the time to write to me
to explain the consequences of adding ./ to the PATH statement.

&gt; Try running the a.out binary with the command line: ./a.out I recently
&gt; installed RedHat 5.2 and found that its $PATH statement does not include
&gt; a path of " ./: " ./ is the path of the current directory that you are
&gt; in. Remarkably, RedHat does not set up paths so that your current path
&gt; is looked at to execute a file.
</PRE>
<P> There is a good reason for RedHat (and hopefully all the Linux distributers)
not to include '.' in your PATH. Its a security risk. Now, you may be OK on
a non-networked system but I don't think it is a good habit to get into.
The following is quoted from the Path Mini HOWTO:
<BLOCKQUOTE>
<H4>12. Security concerns</H4>
<P> The path is sometimes a big security problem. It is a very common
way to hack into a system using some mistakes in path settings. It is
easy to make Trojan horse attacks if hacker gets root or other users to
execute his versions of commands.
<P> A common mistake in the past (?) was to keep '.' in the root's path.
Malicious hacker makes program 'ls' in his home directory. If root
makes
<PRE>
# cd ~hacker
# ls
</PRE>
he executes ls command of hacker's.

<P> Whoops, I read further in your June 2 cent tips, and I see that someone
else has already replied to her message...although they claim the problem
is with e2fsprogs, which I didn't touch on my machine. (Although perhaps
there was an upgraded version in the installer image that I downloaded
along with the new kernel.)

Subject: RE: FTP access methods
<BLOCKQUOTE>
And I finally have a good question: In both Window$ and O$/2 I had apps
that would treat ftp sites as folders (directories). It worked real
well with keeping data in sync off-site. Is there a tool that will
allow an FTP site to be mounted under Linux? It seems fairly useful to
me, but freshmeat and other resources turned up nada.
</BLOCKQUOTE>
<P> Midnight Commander allows you to show an FTP-site in one pane and
your local file system in the other. You can acces the FTP-site like
you would a local directory (i.c. F5: copy, F6: move/rename, etc...)

<P> Pete,
<P> I think the tcp wrapper daemon (tcpd) should do the trick.
In /etc/hosts.allow and /etc/hosts.deny you can use constructs like daemon@host

<P> Try:

man tcpd
man 5 hosts_access (look for 'SERVER ENDPOINT PATTERNS')

<P> Just read issue 41 and read the great article about direct cable

<P> I can get terminal emulation (using HyperTerminal) running at 38400

it goes through the process reporting success at the end but no device
appears anywhere.
</BLOCKQUOTE>
<P> The problem is in Win95/98. It does not come with a null modem
driver. Windows assumes that you are using a REAL modem complete
with AT commands, etc. If all you have is a null serial cable
between the Win95 box and the Linux PPP server, then Win95 cannot
be used because it cannot be set up unless you use a modem and a
phone line.
<P> However, there IS a null modem driver. You install this driver
by copying it to c:\WINDOWS\INF (a hidden directory). You can
then install a new modem. Select not to detect, but you will
pick it from a list. When you get to the list, it will be at
the top of the list of manufacturers, and you can select the
generic null modem driver.
<P> This driver has been around the internet for years, but I have
put it up on my ftp server.
<A HREF=ftp://ftp.nook.net/pub/unix/mdmcisco.inf>

<P> I have no problem then using my Win95 computers with terminal
servers such as my Livingstons. It works a LOT faster than
using a Modem, and communications is typically 115,200.

<H1><font color="maroon">PLIP: Laplink Cable Install of Debian 2.1</font></H1>
<H4>By <a href="mailto:bbennet@mb.sympatico.ca">Bill Bennet</a></H4>
</center>
<P> <HR> <P>
<center><h2><font color=blue>This installs linux via the parallel port</font></h2></center>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Have you got a machine that is ready for linux but it has no CDROM drive? Is it also missing a modem or a network card? If you have a running linux box (with CDROM drive) available to you, then you can easily install linux via the good old laplink cable that plugs into the parallel port. Even old neglected machines come with a parallel port somewhere, so this method will guarantee that you can walk into any installing situation and be ready to roll.<br>
<h2><font color="blue">Debian 2.1 can do this thing</font></h2>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Just about all linux distributions can do this little PLIP console connection. There is a lot of good <a href="#pliphow">information</a> available for you as well, but if it is only for RedHat, then as a Debian user you may feel left out. Even worse, too many times an article will assume that you know what you are doing.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Heck, I do not know what I am doing, but I got this PLIP thing to install Debian 2.1 because I needed a good peer to peer network game player that fits on a small hard disk. Good old Debian has the small purposeful ".deb" packages that you can put in one at a time to make a very small yet powerful server. This article fires up Debian 2.1 and installs a PLIP peer to peer network system with <a href="#xme">X</a> Windows so we can play <a href="#netmaz">netmaze</a> head to head versus a small, bloodthirsty nephew or niece.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The target system is a "Frankenstein"; a 486/DX66 with no CDROM, no modem, no network card, 16 MB RAM, a 1.44 MB floppy and two tiny hard disks, 110 and 170 megabytes small.
<p>We begin at the running linux box that will serve us our CD through the <a href="#laplink">laplink</a> cable.
<h2><font color="blue">Server for the PLIP</font></h2>
<p>We need to login as root and edit these files:<ul>
<li><a href="#initd">/etc/init.d/network</a>
<li><a href="#networks">/etc/networks</a>
<li><a href="#hosts">/etc/hosts</a>
<li><a href="#deny">/etc/hosts-deny</a>
<li><a href="#allow">/etc/hosts-allow</a>
<li><a href="#exports">/etc/exports</a>
<li><a href="#fstab">/etc/fstab</a>
</ul>
<br>
<h2><font color="blue">Scripting is the mojo for linux</font></h2>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Those wacky HOWTO writers are always letting you copy their hard work by giving you a little script to run on your machine.
<p>We need to create this little executable script:
<pre>
#!/bin/sh
killall -HUP /usr/sbin/rpc.mountd
killall -HUP /usr/sbin/rpc.nfsd
echo re-exported file systems
</pre>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Fire up mcedit (it comes with Midnight Commander. You do have it, yes?). Go to the <a href="#NFShowto">NFS-HOWTO</a> and block out the exportfs script with the F3 toggle and then F9 copy it to the ~/.cedit/cooledit.clip file. Exit with F10.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Then type mcedit your-new-file-name. It will give you a nice blank page to F9 insert the ~/.cedit/cooledit.clip file. Edit it in your personal way and F2 save it, or F9 save it as your-new-script-command-name.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Then type chmod 755 your-new-file-name to make it executable. Copy it to /usr/sbin just for fun, but also to make it live in the path.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;For easy mnemonics and to honour the author, we should call it exportfs. Done.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Huh? What does it do? It exports the currently mountable NFS directories in case you make a change.
<a name="initd"><h3><font color="blue">/etc/init.d/network</font></h3></a>
<p>We simply need to tell the machine about the plip1 device and who it connects with via pointopoint networking.
<pre>
#! /bin/sh
ifconfig lo 127.0.0.1
route add -net 127.0.0.0
IPADDR=192.168.1.5
NETMASK=255.255.255.0

#ifconfig eth0 ${IPADDR} netmask ${NETMASK} broadcast ${BROADCAST}
#route add -net ${NETWORK}
[ "${GATEWAY}" ] && route add default gw ${GATEWAY} metric 1
ifconfig plip1 CHGUY pointopoint Salma up
route add -net ${NETWORK} netmask ${NETMASK} dev plip1
</pre>
<h3><font color="blue"><a name="networks">/etc/networks</a></font></h3>
<p>The networks your machine knows about:
<pre>
loopback 127.0.0.0
localnet 192.168.1.0
</pre>
<h3><font color="blue"><a name="hosts">/etc/hosts</a></font></h3>
<p>Well? Who is on this network anyway?
<pre>
127.0.0.1 localhost
192.168.1.5 CHGUY.chguy.net CHGUY
192.168.1.3 Salma.chguy.net Salma
</pre>
<h3><font color="blue"><a name="deny">/etc/hosts.deny</a></font></h3>
<p>Kind of like being doorman at 54, eh?
<pre>
ALL: PARANOID: DENY
</pre>
<h3><font color="blue"><a name="allow">/etc/hosts.allow</a></font></h3>
<p>Salma gets in every time.
<pre>
ALL: 192.168.1.3: ALLOW
</pre>
<h3><font color="blue"><a name="exports">/etc/exports</a></font></h3>
<p>The NFS server will only give out the directories in the exports file.
<pre>
/cdrom *.chguy.net
</pre>
<h3><font color="blue"><a name="fstab">/etc/fstab</a></font></h3>
<p>This will let ordinary users mount the CDROM drive, which is not a problem at a home LAN (Local Area Network. Yes, that is right, your linux CD gives you a replacement for NT).
<pre>
# (file system) (mount point) (type) (options) (dump) (pass)
/dev/cdrom /cdrom iso9660 users,exec,ro 0 0
</pre>
<br>
<h2><font color="blue">Turn it on</font></h2>
<p>Time to turn on PLIP on this CD server <a href="#plipon">machine</a>:
<pre>
ifconfig plip1 CHGUY pointopoint Salma up
route add Salma dev plip1
</pre>
<p>All is ready for the installation.
<ul><li>we will allow the new machine onto the system
<li>we have assigned a network address to each machine
<li>we will export the /cdrom directory when the installer mounts the CD
</ul>
<h2><font color="blue">Client for the PLIP</font></h2>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The target for the installation is the client of your server. However, this is PLIP peer to peer networking, so both of the machines act as a server. For this installation we will refer to the target machine as the client, code named Salma.
<h3><font color="blue">Make two install diskettes</font></h3>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Back at the server, mount the <a href="#CHGUY">B1</a> CD (B2 for a laptop) and make your two installation floppies.
<p>Simply cd deep into the CD:
<br>
<pre>
cd /debian/dists/slink/main/disks-i386/current
dd if=resc1440.bin of=/dev/fd0
dd if=drv1440.bin of=/dev/fd0
</pre>
<h2><font color="blue">Salma Laptop</font></h2>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The resc1440.bin is the generic PC booter; resc1440tecra.bin is made for laptops.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Place your floppy in the drive and power up Salma for the installation.
<br>
<h2><font color="blue">She boots your machine</font></h2>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;You get a nice menu of jobs with the Debian installer. Please read all of your <a href="#fdisk">options</a> and stay loose!
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Debian installation will go through the usual motions of assigning mount points for "/" (root), "/swap", and your custom placements.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Now it is time to "Install Operating System Kernel and Modules" and that is how we will enable PLIP on Salma.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;After the kernel is ready to PLIP we can install the base system, which is a nice little ten MB file that fits on seven floppies. Yes, that is right, you can just make seven more floppies and get it on, no need to use PLIP.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We are here to play <a href="#netmaz">netmaze</a> and make a peer to peer network, so read on.
<br>
<h2><font color="blue">From the floppy</font></h2>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The installer will ask you how you are going to install the kernel and modules, and even though you are going to use the CD in a minute, you must tell it you are going to install from a floppy.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In almost every case you will be selecting /dev/fd0: it is the first floppy drive.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Then it will ask for the resc1440.bin diskette so that you can make a live file system to work from. It booted, so it is already in the drive.
<h3><font color="blue">Kernel Modules</font></h3>
<p><i>You have landed on Community Chest: FOLLOW INSTRUCTIONS ON TOP CARD</i>. <i>Your card says a driver is a kernel module</i>. <i>You no longer will ask for drivers</i>. <i>You will now ask for kernel modules</i>. <i>Do not pass GO</i>.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;When the resc1440.bin diskette is done loading, the installer will ask you to place the Drivers floppy in the drive. It is the drv1440.bin diskette.
<h2><font color="blue">Configure for PLIP</font></h2>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Now the installer wants to jump ahead to Make Linux Bootable Directly From Hard Disk. This is a confounder and we need a volunteer to fix it.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;You need to go down the menu and select "Configure Device Driver Modules". You need your set of modules to be installed in your kernel so that you can network to the CD server.
<h2><font color="blue">The set of modules</font></h2>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;There is a basic set of modules needed for your machine. It varies from user to user of course, and the following list is only a suggestion.
<h3><font color="blue">&nbsp;&nbsp;&nbsp;&nbsp;Group&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Module</font></h3>
<ul><li>block----no, you do not need <strong>paride</strong> right now. Compile it into your custom kernel in future if you want to use external devices, like CDROM drives, etc.
<li>cdrom---no, you will not be controlling the server's CDROM. Get the right one from here if you buy a proprietary CDROM drive in future.
<li>fs------YES, please get <strong>nfs</strong> so you can NFS and export files to your network.
<li>fs------YES, please get <strong>nls_iso8859_1</strong> for the nice character set to read.
<li>fs------YES, please get <strong>vfat</strong> so you can muck about in the DOS file system and see long filenames.
<li>ipv4----YES, please get <strong>rarp</strong> just in case your network tools need it. I do not know; better safe than sorry.
<li>misc----no, you do not use <strong>lp</strong> right now. Compile it into your custom kernel in future if you want to switch from PLIP to printing. If you have two parallel ports then go ahead.
<li>misc----YES, please get <strong>serial</strong> so you can use the serial port for an external modem in future.
<li>misc----YES, please get <strong>psaux</strong> if you are trying to use USB and it craps out as usual. Then you can still use your ps/2 mouse.
<li>net-----YES, please get <strong>dummy</strong> just in case your network tools need it. I do not know; better safe than sorry.
<li>net-----YES, please get <strong>plip</strong> so that you can do pointopoint networking via the laplink cable.
<li>net-----YES, please get <strong>ppp</strong> for future hookups to your ISP.
<li>scsi----no, you might not have any scsi devices. Here is where you get that <strong>ppa</strong> module for your external Zip drive.
</ul>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;When you install the modules and the installer gives you a new screen for parameters, you can usually just press Enter to go ahead.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The plip module will already have the io port address and irq of the parallel port assigned to it, so just press Enter at the parameters page.
<h2><font color="blue">Configure the Network</font></h2>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The installer wants to make linux bootable again, but ignore it and select "Configure the Network".
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;It wants the host name of your system, so type in Salma to match the examples in this article.
<br>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Now it wants to know if you are on a network, so answer yes. The domain name is "chguy.net", just like in the examples.
<h2><font color="blue">The IP address</font></h2>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The IP address can be the default (automatic) numbers thrown up on the screen. These are the numbers for a Class C network, the type you have at home.
<p><strong>Your IP address, according to the examples, is 192.168.1.3 for your hostname of Salma.</strong>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The rest of the numbers are automatic and good ones to use for your network. We have used them for the example and it saves you a lot of typing and checking.
<p><strong>Netmask = 255.255.255.0</strong>
<p><strong>IP Broadcast address = 192.168.1.255</strong>
<p><strong>Gateway</strong> = whatever... If you have a modem on the other machine, then make a gateway. Or a Dell, or a Netwinder, your choice.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Normally from home you will be making a gateway to the internet through your ISP.
<p><strong>Domain Name Service</strong> = your ISP nameserver. Here at home, there is no modem on the two PLIP machines, so I have each machine look at its local address and also on the other nameserver.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;So, for the example, all we put in the nameserver places are the two IP addresses of the two PLIP machines.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We tell the installer that "Another system will be the DNS server".
<p><strong>Nameserver = 127.0.0.1&nbsp;&nbsp;&nbsp;192.168.1.5</strong>
<h3><font color="blue">Execute a Shell</font></h3>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A LeftAlt-F2 will light up a new console for you. A LeftAlt-F3 will show the error messages from your plip attempts. You could also just select "Execute a shell" from that wacky menu.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At the prompt you can immediately type in the ifconfig command to see what is running.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Again with the ifconfig, you set up PLIP on Salma with this:
<pre>
ifconfig plip1 192.168.1.3 pointopoint 192.168.1.5 up
</pre>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Wait, you are not set up yet. You better set a route to the CD server machine.
<pre>
route add 192.168.1.5 dev plip1
</pre>
<h2><font color="blue">Install the Base System</font></h2>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The menu wants to make linux bootable again. Please select "Install the Base System".
<h2><font color="blue">Choose Network Interface</font></h2>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Now we can select "plip: Parallel-line IP" from the menu of interfaces.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Yikes! The friendly installer now tells us that it will not create a complete PLIP configuration.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The installer does not know that you just did it with the ifconfig and route commands. Maybe we can get another volunteer to set up the script to see this step.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Now we are asked to select the installation medium. Yes, it is "nfs: NFS (network filesystem)".
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The installer will ask you for the address of the server and the directory where the debian archive lives.
<h2><font color="blue">"push de button and make it go"</font></h2>
<p><ul><li>the CD is going to be NFS mounted on Salma on /instmnt
<li>you have already mounted the CD on /cdrom on the server
<li>you have /cdrom listed in /etc/exports and now the installer can find it and use the CD.
</ul>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Type in the IP address of the CD server with a colon and the NFS export directory of the mounted CDROM. The screen prompt says "Choose Debian NFS filesystem":
<pre>
192.168.1.5:/cdrom/debian
</pre>
<h2><font color="blue">We are going live to chguy.net</font></h2>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On your screen is a little window called "Choose Debian archive path". It only shows up when you are connected and online with the CD server machine. The installer is asking you for the location of the Debian archive directory in the mounted NFS filesystem.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The answer is /debian. Always is.

<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Your CHGUY Debian 2.1 CD set is labeled B1, B2, S1 and S2. The B1 CD (#1 of 4) is the installer for a regular desktop machine. The B2 CD (#2 of 4) is slightly tweaked for installing Debian 2.1 on your laptop machine. For installing via dselect, either one can go in the CDROM drive. Those wacky hackers are ready for anything.
<h3><a name="xme"><font color="blue">X Windows is compact</font></h3>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;When you install the Standard Server package it only fills up 50 megabytes on your hard disk. Add in 32 megabytes for a swap partition and you have only used 80 megabytes from a small, old hard disk. That will leave you enough room for the xbase ".debs" plus your video-card-specific xserver and the rest of the XFree86 window system.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Both 486s have Apache webserver, anonymous FTP, the TrueType fontserver, full networking, full use of the video card, blazing fast ping times on the PLIP cable (5.2 milliseconds) plus my choice of hot window managers like AfterStep and the icewm.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total installed ".deb" space taken up on either machine is 127 megabytes; including sharp little network games like Freeciv, netmaze and crossfire. Who needs bloated systems? Certainly not the linuxians.

<p>You can make this into an executable script called plipon with:

<p>The above script runs on the CD server CHGUY. Reverse it for Salma.
<p>The new plipoff command:
<pre>

<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;You can copy it to /usr/sbin just for fun and so that it lives in the path.
<h3><a name="netmaz"><font color="blue">Bloodthirsty Midgets</font></h3>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;My six years old nephew Brady "the Mighty Naturta" and his almost-twin cousin Jesse "the NO-baby" absolutely love to play netmaze. It installs in seconds through the laplink cable and it plays for hours. The package is called netmaze and all you do is run the server on one machine and the netmaze client on both. You can even add a few robots to chase you down. The players you see are smiley face spheres. Heaps of fun!
<h3><a name="fdisk"><font color="blue">Three primary and one extended</font></a></h3>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Please use GNU/linux fdisk to make your new primary partition for "/" (root). Too many of you are too excited to get going and you place linux on an <a href="#loadlin">extended</a> partition. Just a reminder, the PC design allows you to get up to four primary partitions per hard disk drive, or three primary and one extended (which you can load up with lots of logical partitions). Do NOT use DOS fdisk if you have just one hard disk. DOS fdisk is disabled so that it will only make one primary partition if you only have one hard disk.

<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I began to think that this was madness! You can get a laplink cable and hook up your two machines for full network connection; plus it is probably a "free" cable that was paid for a long time ago. *Limit of fifty feet, unless you begin to pick up radio signals.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;You plug the laplink cable into the parallel port of each machine; yes, the same place where your printer should go. Your laptop can use this PLIP method to share files with your desktop at work and at home. Plus it is hard-boiled, rock-solid networking through a cable; completely under your control. Methinks this USB thing was just a ploy to sell new machines.

<H1><font color="maroon">An xdm Session</font></H1>
<H4>By <a href="mailto:cwcarlson@home.com">Chris Carlson</a></H4>
[Revised to fix a few HTML tags. Originally published in issue #42.]
</center>
<P> <HR> <P>
<p>
So, you've got X Windows working on your system, you've
set your system to automatically start <i>xdm</i> by setting the default
run state to 5 and now you want to customize your personal windows session
by having certain applications start automatically after you log in.
<p>
At work, I like to log out of my system every evening before I go home
so that others may log in when I'm not there. It doesn't
happen often, but I don't want someone coming into my office and
using a window logged in as me. [You never know when someone gets curious
and starts wandering through my saved mail messages.] The problem is,
I have certain applications that I want brought up automatically, like
my list of things to do and my calendar program.
<p>
In this article, I'm going to explain an X Windows session,
how it is started and what you can do to customize it. It will show
you how to automatically start the window manager of your choice,
have applications start automatically and customize colors and fonts to
your liking. Since X Windows is pretty much identical on all platforms,
much of what I am going to explain can be used on other platforms that
use X Windows other than just XFree86 on Linux. As a matter of fact,
I will make some comparisons between the version of XFree86 that comes
with Red Hat 5.x and what comes with Silicon Graphics IRIX&reg;. You may
note that the files I discuss on both systems have the same name but
are usually just in different directories.
<p>
I realize that other articles have been written about X Windows
configuration, for example Jay Ts' fine article in the December
issue entitled ``X Window System Administration.'' X Windows
is an extremely versatile windowing environment and, because of this,
can be very complex. For this reason, I believe it will require many
articles that might overlap but each will provide information from a
different perspective. This article is intended to be from a user's
perspective, rather than from an administrator's.
<p>
To start off with and to keep my article from becoming a book in itself,
this article is written with the following assumptions:
<p>
<ol>
<li> That you are working with the default configuration of xdm as
it is installed by Red Hat (see <a href="#foot">Footnote</a>). This means that you haven't
changed any of the files found in /etc/X11/xdm. (Since I don't
have an installation of any of the other Linux vendor releases, I'm
presuming their default configuration is identical or similar enough
that it won't cause any problems.)
With this in mind, I will refer to filenames that are used and
referenced by xdm (and their contents) as specified in the installed
configuration file. It should be noted, however, that almost all of
these filenames can be changed by modifying /etc/X11/xdm/xdm-config
or by specifying a different configuration file on the command
line when starting xdm. (On the SGI, the configuration file is
/var/X11/xdm/xdm-config and I have seen some installations use
/usr/lib/X11/xdm/xdm-config.)
<li> That you have a basic understanding of the server/client concept
used by X Windows. i.e. The X server handles the display and keyboard
and runs as an application. User's applications are clients that
request services from the X server to display things and provide input.
<li> That you have some familiarity with X resources and how they
are used in the X environment.
</ol>
<p>
<h3>User Session Initialization and Termination</h3>
<p>
When the X server is started automatically via <i>xdm</i>, the user is
presented with a login screen. When a user successfully logs in via this
screen, <i>xdm</i> starts the ``user session''. This session is
a shell script which, when it terminates, ends the user's session
and <i>xdm</i> resets the X server and returns to the login screen.
<p>
Prior to starting a session, <i>xdm</i> runs a small startup script with
root privileges to perform any user initialization that may be required.
Currently, this file, /etc/X11/xdm/GiveConsole, changes the ownership of
/dev/console to that of the user so messages sent there can be displayed
on a window in the user's environment.
<p>
In like manner, when the session ends, xdm runs another small exit script
with root privileges to clean up anything that might have been set up by
the startup script. Currently, this script, /etc/X11/xdm/TakeConsole,
changes the ownership of /dev/console back to root.
<p>
Note that these two files are /var/X11/xdm/GiveConsole and
/var/X11/xdm/TakeConsole on the SGI.
<p>
The step of interest to this article is the actual starting of the user
session itself. Here, <i>xdm</i> starts a subprocess running the script
/etc/X11/xdm/Xsession (/var/X11/xdm/Xsession on SGI) and waits for it
to exit. When it does, <i>xdm</i> processes the exit script and returns
to the login screen. This session script is run with the user's
privileges.
<p>
A resource has been set for <i>xdm</i> which causes the parameter
``failsafe'' to be passed to the user session if the user uses
the F1 key rather than the Enter key to complete his/her login. This can
be very useful if the user makes a mistake in his or her customized
session script which makes it impossible to log in. How this feature
is taken advantage of is discussed below. It should be noted that I
found this resource defined for both Linux and SGI and is used in an
identical manner on both.
<p>
<h3>The Xsession File</h3>
<p>
The /etc/X11/xdm/Xsession file provided by Red Hat is quite simple,
especially when compared to the /var/X11/xdm/Xsession file provided with
the SGI. This file is a standard Bourne shell script which performs
all the user startup and initialization that the system administrator
wants done for all users.
<p>
As described above, if the user logs in and pressed F1 rather than
the Enter key, the parameter ``failsafe'' is passed to the
session file. The first thing the /etc/X11/xdm/Xsession file does is
check if this parameter exists and, if it does, exec's an xterm.
This bypasses all other initialization and provides the user with a
terminal window to work with. Notice that this is a good method of
logging in if the user has done something to his/her personal session
file that otherwise prevents logging in.
<p>
For those that don't understand the function of exec, this is a
builtin command provided by all the standard shell programs. It causes
the current running shell to be replaced by the exec'd program.
Thus, the current running shell never returns from an exec (unless the
program referenced fails to start for some reason) and the parent process
is not aware of any change in the child process. The exec'd
program retains the process ID of the shell and, when it terminates,
it is as if the shell terminated and the user session ends.
<p>
Presuming ``failsafe'' is not a parameter passed to Xsession,
the script continues by redirecting stderr to an error file. If it can
write to it, this file will be .xsession-errors in the user's home
directory. If the session can't write to the user's home
directory or this file is write protected for some reason, the script
will attempt to use /tmp/xses-$USER, where $USER is the user's
login name.
<p>
This error file is useful for determining problems during the user's
session. Any errors generated by applications that are started (including
the window manager or applications started by the window manager)
will be sent to this file. If the user has problems starting a user
session after logging in, he/she can perform a ``failsafe''
login (as described above) and look at this file. The error messages
may be of some help in determining the problem.
<p>
Finally, the standard Xsession file transfers control to one of a set of
shell scripts, depending on their existence and if they are executable.
It does this with the exec command which means that, whichever program is
run, it replaces the Xsession process and becomes the new user session.
The shell scripts are:
<p>
<pre>
1. $HOME/.xsession
2. $HOME/.Xclients
3. /etc/X11/xinit/Xclients
</pre>
Some interesting notes about this compared to the script used on an
SGI computer. SGI does not require the scripts to be executable but
will run /bin/sh against them if they aren``t. Also, SGI only looks
for $HOME/.xsession. If this file doesn't exist, the system Xsession
file sets up the default user environment provided by SGI. Red Hat
chose to break the default user session into two steps, since the
standard installation will provide /etc/X11/xinit/Xclients.
<p>
If none of the three files above exist or are executable, then the
user``s .Xresources file is loaded (if it exists) and the program
<i>xsm</i> is exec'd. <i>xsm</i> is one of the many window managers
provided with Red Hat Linux.
<p>
<h3>User Customized Xsession File</h3>
<p>
As you may have guessed from the above explanation of the
system's Xsession file, the user can create his/her own shell script
which will be processed as the user session. This is a very powerful
capability and provides each user the ability to do whatever processing
they want each time they log in via the X login. In this script,
the user can start various applications, set root window resources,
set one-time environment variables, change default keyboard definitions
and select a window manager.
<p>
The easiest way to set up your own personal Xsession file is to copy
the system /etc/X11/xinit/Xclients file into your home directory as
.xsession or .Xclients (what, in the future, I will refer to as the
user's Xsession file) and then edit it as desired. I'm not
going to step through the contents of the /etc/X11/xinit/Xclients file,
you can do this on your own. I'm going to just explain some of
the things one might want to do.
<p>
One important thing is to load desired resources into the root window.
This is usually done with the following commands:
<p>
<pre>
resources=$HOME/.Xresources
if [ -f &quot;$resources&quot; ]; then
/usr/bin/X11/xrdb -load &quot;$resources&quot;
fi
</pre>
Another thing that the user may wish to do is set the root
window background to something different. This is done with the
<i>/usr/bin/X11/xsetroot</i> command. For example, I have my background
defined as follows:
<p>
<pre>
/usr/bin/X11/xsetroot -solid DarkSeaGreen4
</pre>
Note that this command can also be used to set the default cursor
and cursor color for the root window, a two-tone plaid pattern for the
background or an X bitmap to be used as a pattern.
<p>
Also, the command <i>/usr/bin/X11/xset</i> can be used to set the
desired bell volume, key click, DPMS (energy saving) features and
mouse parameters. This command can also set autorepeat and screensaver
parameters.
<p>
If you want to define special keys, you can run <i>/usr/bin/X11/xmodmap</i>
from this script. For example, I like to be able to access the full
ISO 8859-1 character set and insert internationalized characters in
my documents. Also, Linux likes to define &lt;Shft&gt;F1 to be F11
and &lt;Shft&gt;F2 to be F12. Since my keyboard has an F11 and F12,
I prefer these keys to be set to F13 and F14 respectively. To handle
this, I have defined $HOME/.xmodmaprc to contain the following:
<p>
<pre>
keycode 113 = Multi_key
keysym F1 = F1 F13
keysym F2 = F2 F14
keysym F3 = F3 F15
...
keysym F10 = F10 F22
keycode 95 = F11 F23
keycode 96 = F12 F24
</pre>
Then, in my $HOME/.xsession file I have the following:
<p>
<pre>
if [ -r $HOME/.xmodmaprc ]; then
/usr/bin/X11/xmodmap $HOME/.xmodmaprc
fi
</pre>
Finally, the most important step is running a window manager.
Red Hat likes to run <i>fvwm</i> because it can be set up to look a lot
like Windows 95&reg;. Since I use SGI computers a lot, I prefer Motif (which
costs money and doesn't come with Linux normally). There is also
<i>xsm</i> and <i>twm</i> available. You might want to read the man pages
for each to determine which window manager you prefer.
<p>
If it is desired, the user can exec the window manager as the last
thing in the Xsession file. This will mean that the user has to end
the window manager to end their session and return to the login screen.
I prefer to run the window manager as a background process and exec an
xterm as the last thing. This way, when I exit the xterm session, the
user session will end and the login screen will be brought up. Note that
the window manager and any window applications will be terminated because
the X display will be closed. Any non-window applications started as
a background process will not be terminated automatically and could
continue after the user's session ends.
<p>
I start the Motif window manager as follows:
<p>
<pre>
/usr/bin/X11/mwm
</pre>
I start the final xterm with:
<p>
<pre>
exec nxterm -geometry 80x50+10+10 -ls
</pre>
This creates a version of the xterm that supports color. It will be
80 characters wide and display 50 lines. The window will be positioned
in the upper left corner of the screen (at pixel position 10x10).
The last option forces nxterm to run the shell as a login shell.
<p>
>From within the user's Xsession file, you can run a number of
xterms, xclock or whatever, all of which will start automatically when
you login. Be sure to specify a geometry (with the -geometry option)
to get each application positioned on the screen where you want it.
<p>
Also, remember to run the applications in the background (by terminating
the line with ``&'') otherwise, the user Xsession file will
wait until that application terminates before continuing.
<p>
<h3>Important Tricks</h3>
<p>
Here I want to discuss some more interesting and important tricks
that can be done from the user's Xsession file.
<p>
All window managers can execute programs from a pulldown menu. Sometimes
these programs need special environment variables defined prior to
their execution (for example, Netscape may need SOCKS_NS to be defined).
Since the user's environment variables are not usually set until
a shell is started, the window manager and any programs started from
the window manager will not have the user's environment defined.
Trying to set them in $HOME/.cshrc, $HOME/.profile or $HOME/.login
won't do any good.
<p>
One trick is to define these environment variables in the user's
Xsession file. It is necessary to set these environment variables before
you start the window manager.
<p>
Another trick that I like to do is define XUSERFILESEARCHPATH in my user
Xsession file. Most applications look for and use a application resource
file, usually found in /usr/lib/X11/app-defaults. For example, Netscape
uses the file /usr/lib/X11/app-defaults/Netscape for its application
resource settings. If you want to change any of these settings for your
personal environment, you can copy this file into your home directory
and modify it. Next time you run Netscape, it will find the one in your
home directory first and use it.
<p>
I have found my home directory cluttered with application resource files
and wanted to put them into my own private app-defaults directory. I did
this by creating the directory and copying all the resource files into it.
Then, I set XUSERFILESEARCHPATH to the following in my user Xsession file:
<p>
<pre>
/home/carlson/app-defaults/%N:/usr/lib/X11/%L/app-defaults/%N:/usr/lib/X11/app-defaults/%N
</pre>
This makes the application search in /home/carlson/app-defaults
for application resource files before going to the default locations
under /usr/lib/X11.
<p>
One last trick is for those of you that have multiple computers all
running X servers. Here at home, I have an SGI O2 and my Linux machine.
When I log in remotely to my O2, I want to be able to run X applications
and have them use the display on my Linux box. In order to do this,
I need to run <i>xhost</i> each time I log in to my Linux box to allow
remote logins to access the X server.
<p>
As part of my user Xsession file, I have the following line:
<p>
<pre>
/usr/bin/X11/xhost +moonlight
</pre>
This sets the X server on my Linux box to allow access from
moonlight, the name of my O2.
<p>
<h3>Conclusion</h3>
<p>
I hope you have found this information useful and interesting.
I've tried to show you how to create your own user Xsession
file to start applications, set a special environment and run your own
window manager. I'm sure you can come up with many more ideas.
<p>
One useful tool that I wrote, based on a similar application provided
with SGI, is <i>userenv</i>. This application creates a login shell as
a child and has it print its environment. This environment is collected
and then printed to stdout in a form that can be executed to create the
same environment by a shell.
<p>
In my user Xsession file, I have the following line:
<p>
<pre>
eval `userenv`
</pre>
This computes my user environment and echos it in a form that
the shell can execute the output to create the same environment.
The <i>eval</i> command causes the output to be processed by the shell.

<h3>Footnote</h3>
<p>
I am running Red Hat 5.1 but it appears that it
hasn't changed significantly for a few years. Also, I find the
configuration almost identical with other Unix platforms such as Silicon
Graphics IRIX&reg;. The only differences appear to be in what directory
files are maintained.)

<H1><font color="maroon">Getting Involved in Open Source</font></H1>
<H4>By <A HREF="mailto:andrew@ultraviolet.org">Andrew Feinberg</A></H4>
</center>
<P> <HR> <P>
<EM>How to join and render help to the Linux community.</EM>
<p>
Linux has always been maintained by volunteers. In fact, the ``gift
culture'' of the Open Source community has always been one of its strong
points. However, the majority of users who would like to contribute do not
know how to get involved. This article will discuss aspects of becoming
active in the Open Source community and contributing to the Linux
kernel and other projects, including my experiences with becoming involved
in the Debian project.
<p>
<h3>The Kernel</h3>
<p>
The contributors file in /usr/src/linux on my home system is huge. My
linux-kernel mailing list folder is always full of mail from people,
eagerly discussing the ins and outs of improving this operating system. Many
people assume that Linus is the sole author of Linux. Not true, I tell
them. Linux is the prime example of the ``benevolent dictator'' model of
open-source development. A prospective developer submits code to Linus or
one of the few ``lieutenants'' such as Alan Cox. They decide what will go
into the kernel.
<p>
Another scenario is that certain parts of the kernel,
such as the kernel NFS system, have a maintainer.
Code is submited to them, and they decide what goes into their part
of the kernel. Occasionally, Linus or someone will ask for a person to take
over a part of the kernel. If you volunteer, make sure you know the code
and can handle the responsibility of maintaining it and accepting patches.
Be prepared to handle loads of mail if something breaks. Also, make sure
you are on the linux-kernel mailing list.
<p>
<h3>GNOME</h3>
<p>
One of the more exciting developments in the past year has been the effort
to provide Linux with an easy to use desktop. One of the two front-runners
in that effort has been GNOME: the GNU Network Object Model Environment.
Unlike the kernel, GNOME uses CVS, a version control system, to keep track
of code submitted by developers around the world. This eliminates the need
for someone to patch sources by hand to create an upgrade. To get CVS
access to GNOME, send mail to Miguel de Icaza (miguel@kernel.org). Include
a description of what code you will be writing, along with an encrypted
password. More information is available at <A HREF=http://www.gnome.org/>
http://www.gnome.org/</A>.
<p>
<h3>Debian</h3>
<p>
Debian GNU/Linux is unique in that unlike most other distributions, it is
maintained entirely by a team of volunteers from all over the world.
Becoming a Debian developer entails your maintaining a package;
that is, you will make sure the latest version is on the Debian FTP
site and that bugs get fixed as soon as possible fixes are done by you, if you
package your own software, or the upstream maintainer, if you package
someone else's software. or the software of a project such as GNOME or
Mozilla. Because developers can place packages into the distribution
tree, Debian is rather strict on security issues, especially when it comes
to letting new developers into the project. A PGP key, (or coming soon,
GNUPG) key is a must, and this key must be signed by another Debian
developer. This may seem Draconian, but it is imperative that they be sure
that the developers are who they say they are. After they receive your
PGP/GPG key (signed), someone may call you for a telephone interview. This
will consist of asking you a few questions, generally about the package(s)
you intend to maintain. The whole process takes time, but it ensures
the distribution is secure.
<p>
<h3>Wrapping It Up</h3>
<p>
The open-source development model allows talented people to collaborate on
projects from across the world. If someone feels they have something
useful to contribute, they can. This article only touches on three
projects. The Open Source movement is truly a ``gift culture''. You are
judged by what you have contributed and the quality of your code.
Countless projects are out there that can benefit from the
assistance of the community. With your help, they can flourish, and you
may be ``known by your initials''.

<H2>Introduction</H2>
<P>Recently an article was published in Linux Gazette entitled <B>Web
Page Design Under Linux</B>. This article produced some criticism in
later issues. The main criticism seems to have been of the authors
preference for hand coding HTML rather than using a HTML editor like
the Windows HotDog editor. This is an argument I do not really want
to get involved with. Neither do I want to spend much time on style.
Whilst in most cases users want simple fast loading, clear pages,
there will always be a place for garish eye candy, huge graphics and
all kinds of complexities that take forever to download on a 28k
modem. What I do want to address are the great things that linux
offers. Great things that are free and would cost a fortune to
implement on other operating systems. In particular I shall explain
how to set your linux box up to be your own intranet server, and
thereby fully exploit the abilities Linux offers for designing
applications for the Web.
</P>
<p>
One point I think needs making, and which does not fit in with the rest of this
article, is the <b>Plugger</b> Plug-in for Netscape Navigator. In the past
many people have complained that Netscape plug-ins are not generally available
for Linux. Plugger from <a
href="http://www.infovav.se/=hubbe/plugger.html">http://www.infovav.se/=hubbe/plugger.html</a>,
seeks to address this by providing support for many audio/video/image types.

<H2><A NAME="bwd1"></A>Wysiwyg Editors</H2>
<P>By way of introduction though, I will put my two penny worth into
the 'editor argument'. I have never yet found a HTML editor that I
like! I am writing this article in StarOffice 5.0. I have never used
it to write HTML so this is something of a test. I expect I'll have
to edit the source when I finish writing. Another editor that seems
as good as any other I have tried is the composer part of Netscape
Communicator. I find this irritating, very very irritating. Why?
Because I like my text to be fully justified. OK I know that some
people think that full justification 'goes against the spirit of
HTML', but personally I would rather read text that is fully
justified than text which is not. I do not believe I am alone in this
preference.</P>
<P>What happens with Netscape is that after I have spent a couple of
hours designing some pages until I am happy with them, I load them
all into vi and change every occurrence of <B>&lt;P&gt;</B> into <B>&lt;P
align=justify&gt;</B>, which can take some time if I've written a lot
of text. Now a little later I want to make some changes, so I load
the pages into Netscape Composer and I make some changes. But whist
Communicator understands <B>&lt;P align=justify&gt;</B>, Composer
does not. In fact Composer does not allow <B>&lt;P align=justify&gt;</B>
and changes each occurrence back to <B>&lt;P&gt;.</B>... Bummer... I
have to re-edit all the source by hand again. If I thought there was
some advantage to using Composer, rather than hand writing my HTML I
guess I would write a little program to search HTML files for <B>&lt;P&gt;</B>
and replace with <B>&lt;P align=justify&gt;</B>. But this is not the
only short coming of HTML wysiwyg editors. They just don't seem able
to do exactly what I want, how I want.
</P>
<P>OK in fairness I am now impressed with StarOffice! Although there
is no button to give full justification, it is easy to edit the <B>Text
Body style</B> so that full justification is automatic. It is also
easy to automatically indent the first line of a paragraph, set
double line spacing etc. etc. Maybe I will be converted to using a
wysiwyg editor for my HTML after all.
</P>
<P>One feature that seems to be missing from StarOffice 5.0, is any
easy way to define lists. Tables are well supported, but lists are
not. I guess that it should be possible to define some new styles to
allow the use of different kinds of list, but one would have thought
that a button should be available for them. Also given the different
kinds of list available for HTML, one might find that the styles menu
becomes cumbersome and more difficult than it should be.
</P>
<P>OK simple layouts are quicker with a HTML editor, but if you want
full control you have to hand edit at some point. So to my way of
thinking if you want to write good HTML you must learn HTML. It is a
very bad idea to to think you can skip learning HTML by getting an
editor that works like a word processor. You will not have the skills
you need to produce good web pages. HTML is very easy to learn. Once
you know it then you might find that Netscape or StarOffice provide
useful tools to help you. But please do not think such tools replace
the need to be able to hand code HTML.
</P>
<P>The essential document to read if you want to produce great
Web-Pages efficiently is <A HREF="http://www.w3.org/TR/REC-html40">HTML
4.0 (W3C: HTML 4.0 Specification)</A>, this is the full Document Type
Definition for HTML and SGML. For once I have taken my own advice and
read it! The problems I mention above regarding text formatting have
all been solved for me! I look at the HTML source StarOffice has
given, whilst I am impressed, I am not happy. Again I think that an
editor like <B>vi</B> or <B>emacs</B> really is better and more
efficient than using a <B>wysiwyg</B> editor.
</P>
<P>The reason is that HTML 4.0 allows the use of <B>Style Sheets</B>.
This article depends upon the use of a style sheet, <A HREF="./gibbs/special.css">special.css</A>.
This is a document that says how a browser should render my document.
An important feature is that browsers that cannot display certain
things (e.g. graphics) are not disadvantaged. All browsers can access
this page in the way I intend them to. In the past authors have been
forced to use techniques to format their pages that cannot be
displayed correctly on all browsers. Propriety HTML extensions, the
conversion of text into graphics, the use of images for white space
control, the use of tables for layout and even the use of programs,
have all been used to format text, all these methods cause difficulty
for users and extra work for developers. The correct use of style
sheets avoids these problems.
</P>
<P>Once you are familiar with the use of <B>style sheets</B>, it will
not matter how badly Netscape Composer performs, or how unfamiliar
you are with StarOffice, using an editor like <B>vi</B>, really can
be simpler than using something like <B>Hotdog</B>. Load <A HREF="./gibbs/special.css">my
style sheet</A> into your favorite editor and see for yourself how
easy it is to change the look and feel of this document.
</P>
<p>STOP PRESS.....
<P>Even as I am writing this document, I have found yet another web browser
for linux! This one is worh some attention since it is produced by the W3
consortium, the same people who define the HTML specification. In fact
this is the browser they use to test their specification. The following text
is displayed when you start it for the first time:-
<dl>
<dt><b>Amaya</b></dt><dd> is a Web client that acts both as a browser and as
an authoring tool. It has been designed with the primary purpose of
demonstrating new Web technologies in a WYSIWYG environment. The current
version implements HTML, MathML, CSS, and HTTP.<br><br></dd>
<dt><b> Main Features</b></dt><dd>
With Amaya, you can manipulate rich Web pages containing forms, tables and
the most advanced features from HTML. You can create and edit complex
mathematical expressions within Web pages. You can style your documents
using Cascading Style Sheets. You can publish documents on local or remote
servers with the HTTP Put method.<br>
Browsing and authoring are integrated seamlessly. You can browse and edit
Web pages at the same time. For that reason, a simple click just moves the
caret to allow text editing; to follow a link, you have to double click.
<br><br></dd>
<dt><b>Online Manual</b></dt><dd>
A User's Manual is available online. You can browse it with the Help menu,
which displays each section separately. You can also print it: just follow
the Online Manual link below. You'll get the front page. Then build the
whole book with the "Make book" entry from the Special menu and print the
result.</dd>
</dl>
<p>
This browser certainly has some advantages. The version I have is still beta
(1.3b), so there are some short comings. I found that the <b>File -
Open Document</b> dialog can resize its file box so it is non-functional.
Also for some reason not all directories can appear in the directory box. At
least one can specify the required file in the <b>URL</b> box! The fact
that the manual does not come with the package is a definate minus for me.
<p>What is nice about the browser is the pleasent way it renders pages. This
page, for instance, uses full text justification, Amaya can actually split
words in the traditional manner when required.
<p>
The really nice thing about this browser is the fact that you can edit files as you browse them. So if you are creating a document with many pages it is
easy to switch between them. The down side of this is that there seems to be
no way to to edit or view document source. Something that I would like to
see in other browsers is the ability to create a "Table of Contents", with
Amaya you can generate one based on the <b>&lt;H...&gt;</b> elements in your
document. This will pop up as a seperate window and allow you to easily
navigate through a document that has no links of its own.
<p>At about 4.5 Megbytes, this is probably a very good alternative to
StarOffice if you do not have the disk space required for StarOffice. I
am certainly interested in seeing how this browser develops in the future.
If you want to give it a try you can obtain it from <a href="http://www.w3.org/Amaya">the Amaya homepage</a>. Additionaly there was a review of an earlier
release of Amaya in Linux Gazette some years ago <a href="../issue15/amaya.html">see issue 15</a>. All I have to add to that review is that improvements must have been made. It seems the same in appearence as the screen shots show. Amaya displays the old style of Linux Gazette Contents pages quite well, but the new style in the last three or four issues is completey garbled. When Amaya starts up it no longer looks for a page on its home site, and
I have not seen it seg fault as described. On the whole it does a very good job.
<H2><A NAME="bwd2"></A>The Advantage of Linux</H2>
<P>Now I've got that out of my system I'll get on to my main point.
Drum roll please..... With linux it is simple to build a system you
can gain http access to. Trumpet fanfare please.</P>
<H3>Why is http access to your machine important?</H3>
<P>Even if, like me, you are a stand alone machine, with no kind of
network, it is easy to start up your favorite browser and <B>http://</B>
yourself. This means you can get into the wonderful worlds of cgi
scripts, client server applications, java. etc. etc. etc. Without the
need to access a 'real' network you can test any network application
you care to develop for the Internet. You can test every aspect of
your web design without wasting a phone bill. You can test
applications safe in the knowledge that no matter what mistakes are
in your code, only the machine you are using will be at risk, the
&quot;<I>real</I>&quot; network will be unaffected until you decide
your code is working correctly.</P>
<P>Web page design is not just about putting text/graphics and links
onto the Internet. Increasingly it is about providing good user
interfaces to network applications and providing an efficient means
of communication. In the past only the largest corporations could
afford to implement a WAN (Wide area network). Today anybody with a
modem and pc can join the Internet, or implement their own intranet
(a private network that acts in the same way as the Internet).</P>
<P>To illustrate my points consider the following scenario. You own a
small tobacconists and live in a village called Tiny. Because the
village is small you do not have many customers, so you don't sell
items in vast numbers. That means you do not buy in large quantities
from your suppliers and you cannot get the kind of discounts larger
shops would get. But you have many relations and friends in other,
similar villages who also run small tobacconists. If you all clubbed
together and ordered your supplies as one entity you could take the
discount advantages of bulk buying from your suppliers. The only
problem is knowing which shop needs what items at any given time. You
know that the discounts you would get would allow you to employ a van
driver to deliver to all the shops and still leave each shop a
significant saving.
</P>
<P>How can web design under linux help you solve this problem?</P>
<P>The 'man with a van' needs information, what to buy in what
quantity and where to deliver it. This sounds like a classic database
application. Linux offers many sql database solutions. We want to
keep costs to a minimum, we also want to maximize security and
reliability. So good choices might be ingres or postgreSQL. If we
look at these DBMS's we find that postgreSQL comes with a java
interface. So lets say we design a suitable database with postgreSQL.
This database will be held on a box that will be our server.
</P>
<P>What we need is the ability for each shop to communicate with the
server to tell it what stock we need to buy in. Shop keepers do not
have to be computer literate. They also do not want to spend much
money on computer systems. At least at this time it is unlikely that
they could be persuaded to learn a UNIX operating system like linux.
Cheap boxes already have Windows. An ideal solution is one where each
shop can dial into the server, the manager can start up his/her
favorite browser and use it to enter information to the server. It
should not matter what operating system each shop uses.
</P>
<P>What does our server need to do?</P>
<P>The first thing is to get Apache set up and running. Apache is a
web server and comes with most if not all linux distributions as
standard. What is not always clear is how to set it up correctly.
This is something an installation program cannot do (easily) and
needs to be done by hand. It is Apache that allows us to http
ourselves. Of course, we will also need to allow remote machines to
dial into our server, but that is a matter outside the scope of this
document.
</P>
<P>Once Apache is running we can design a java application to act as
a user interface to our database.</P>
<P>We can test both the client and the server parts of our
application on our server until we are certain it performs as
required.
</P>
<P>Then all we need to do is allow the shopkeepers to be able to dial
into the server and gain access via their browsers to the java
database interface.</P>
<P>The wonderful thing is that at the test stage we only need to use
one linux box which acts as both client and server at the same time.</P>
<H2><A NAME="bwd3"></A>Setting up Apache</H2>
<P>If you do not already know, then Apache is one of the most common
http servers in existence. A great many ISP's (Internet Service
Providers) use Apache to give their clients (i.e. You) access to the
world wide web.
</P>
<P>This document does not attempt to address the requirements of a
true Internet or intranet server. All I am concerned with here is
getting Apache up and running on a standalone machine so that
client/server software can be tested. In particular I am not
concerned with security issues here. If you do not intend to have a
permanent network connection then all should be well. If you intend
other machines to have access to your http server then you should
read all the relevant documentation. Complete configuration of Apache
can be a very complex issue which does not fall within the scope of
this document.</P>
<P>Modern Linux distributions, such as S.u.S.E., have special
requirements for setting up Apache correctly. To avoid confusion
please read the documentation that came with both your linux
distribution and your Apache distribution. The following steps will
work for any Linux distribution, but be warned, if your distribution
has special requirements I cannot be responsible for getting your
system startup files in a mess.
</P>
<P>For instance I shall describe how to start Apache automatically at
boot time by adding a line to your /etc/inittab. Whilst some
Slackware users will benefit from this approach S.u.S.E. users should
find that it is better to edit their /etc/rc.config file in the
appropriate manner.</P>
<H3>Preparing your machine for Apache</H3>
<P>These steps will prepare your machine for the installation of
Apache. You might find that Apache is already installed, following
the above steps will not hurt such installations.
</P>
<OL>
<LI>Make certain you have set your <B>/etc/HOSTNAME</B>
correctly. I call my machine <B>Hawklord</B><br><br>
<LI>Create a new account for the httpd
administrator. I use the user <B>wwwrun</B>, whose primary group is
<B>nogroup</B> (65534).<br><br>
<LI>Edit your <B>/etc/hosts</B> to reflect the name
of your machine. I have the entries
<PRE> 127.0.0.1 localhost
127.0.0.2 Hawklord.Varteg Hawklord </PRE>
<LI>Edit your <B>/etc/hosts.allow</B> I have
<PRE> ALL: 127.0.0.1
ALL: 0.0.0.0
ALL: localhost
ALL: Hawklord.Varteg
</PRE>
</OL>
<P>If Apache is not already installed, find a pre-compiled version
and install it as per the instructions. You should find that
configuration files are placed under <B>/etc/httpd</B>, and other
files are installed under <B>/usr/local/httpd</B>.</P>
<P>The directory <B>/usr/local/httpd/htdocs</B> should contain the
Apache user manual in html format. Actually this directory will
become the root directory of our http site, so you may want to move
this documentation elsewhere eg. <B>/usr/doc/Apache</B>.
</P>
<H3>Plan your http site</H3>
<P>When you log into a http site, eg <B>http://linux.org</B>, you
find yourself at the root of what can be a very complicated directory
structure. You can think of a http site as being a file system just
like your own root file system. Whilst it is true that to a user the
http site will look like a regular file system, the reality on the
servers hard disk(s) can be very different. It is important to
understand the differences and use them to your advantage.
</P>
<P>On my system the document root is at /usr/local/httpd/htdocs, and
this is the directory a user lands in when they access
<B>http://Hawklord.Varteg</B>. But there is only one file and no
sub-directories on my hard disk. I only keep index.html in the
physical location /usr/local/httpd/htdocs. All the documentation
users can access is held in other locations on my hard disks.
</P>
<P>Looking again at /usr/local/httpd you should find other
sub-directories, in particular cgi-bin and icons. These directories
should seem to be located under your document root because they will
contain files that should be available to any html file on your site
that requires them. Though a user should not be able to directly
access these directories. Much of my documentation is under /usr/doc,
so I make that directory appear as /doc to the http server.</P>
<P>What this means is that you can store all your documentation on
the server in locations that seem logical to you, you do not need to
copy files or even make symbolic links to /usr/local/httpd/htdocs.
Instead plan how you want your documentation to appear to a user.
Also you can have directories that users cannot directly access, but
which html documents can access.
</P>
<P>For instance, the directory <B>/usr/doc/</B> contains
</P>
<PRE STYLE="margin-bottom: 0.50cm"> Linux_gazette Howto Ldp java-documentation</PRE>
<P>
I also want to access files under <B>/usr/hobbies/literature</B> and
<B>/usr/src/java/applets</B>
</P>
<P>I want my site to have the following structure:
</P>
<PRE> / ---&gt; cgi-bin
docs ---&gt; Linux_gazette
Howto
Ldp
java-documentation
literature
icons
java_applets
</PRE>
<P>
Planning your http site in this way will save you headaches in the
future!</P>
<H3>httpd.conf</H3>
<P><B>/etc/httpd/httpd.conf</B> is the main configuration file for
Apache. Some versions of Apache and/or Linux distributions recommend
that all configuration information is kept in this file. Other
versions recommend that you use all three files I shall mention
below. If you want to keep all information in one file, simply put
all the information in one file, there is no real difference between
the two methods. You will find that the example files will contain
sufficient comments to enable you to make the best choices for your
system. I am only going to describe the changes you need to make to
get Apache to work for you. Careful reading of the files will let you
configure Apache better for your needs.
</P>
<P>I am aware that a TCL configuration utility called <a href="http://butler.disa.mil/ApacheConfigClient">Comanche</a> exists for Apache.
However, this is still in an early stage of development, so I do not
recommend it for beginners. I found in practice the utility would not
function correctly if you use only <B>httpd.conf</B> to configure
your system. However it could prove useful for experimenting with different
configurations.
</P>
<P><B>For each line in the configuration files you can assume that
your example file has a correct or sensible entry, unless I
specifically mention it. Back up the examples before you make any
changes!</B></P>

This is the address Apache will use to send e-mails with details

<B><I>ServerRoot</I> /usr/local/httpd</B></DT><DD>
This should point to the location you installed Apache's main files.
By default this is <B>/usr/local/httpd</B><br><br></DD><DT>

index.html is a sensible default.<br><br></DD><DT>
<I><B>Alias .....</B></I></DT><DD>
Each line starting <B>Alias </B>will define a virtual directory on

</dD>
<dt><I><B>ErrorDocument</B></I></DT><DD>
Error documents are the response the server will give when the user
types a wrong <B>URL</B>, or tries to access a restricted file or
directory etc. Apache gives good default error documents, but you
can override this behavior and provide your own responses. I keep my
error documents in the directory <B>/usr/local/httpd/error</B></DD></DL>
<H3>
access.conf</H3>
<P>This file contains permissions for our sites directories. If. when
you test your configuration by starting <B>httpd</B> and pointing
your browser to (eg.) <B>http://Hawklord</B>, or <B>http://localhost</B>
(both will work for the above example), you get a file access error
you will need to alter this file. Each directory in your site should
have its own entry.
</P>
<P>By default Apache has a very restricted set of permissions for the
root directory, I have found that changing to:
</P>
<PRE> &lt;Directory /&gt;
Options All
Order allow,deny
Allow from all
Options FollowSymLinks
&lt;/Directory&gt;</PRE>
<P>
solved some problems for me. It is important to realize that a
directory inherits its permissions from its parent directory. So if
you want to allow outside access to your site you need to take great
care when setting up your directory permissions.
</P>
<P><BR><BR>
</P>
<H2><A NAME="bwd3.1"></A>Starting and Testing Apache</H2>
<P>Once you are satisfied that you have correctly installed and
configured Apache, you will want to test it! Log into your machine as
root. At the prompt type:
</P>
<PRE> #: httpd &amp;</PRE>
<P>Now you can log into your machine as any user, start your favorite
browser and enter the <B>URL</B> <B><I>http://localhost</I></B>. If
all goes well you should load the Apache site file <B>index.html</B>.
That is unless you moved the Apache documentation and provided your
own <B>index.html</B> in <B>/usr/local/httpd/htdocs</B>
</P>
<P>Once you ar satisfied that all is well, you will want to have
<B>httpd</B> start at system boot time. Some Linux distributions,
such as Red-Hat or S.u.S.E. will have a script to start Apache in
their <B>init.d</B> directory. If this is the case then you just need
to enable the script for <B>sys V init</B> in the normal manner.
</P>
<P>As an alternative you can put the following line in your
<B>/etc/inittab</B>
</P>
<PRE STYLE="margin-bottom: 0.50cm"> ap:45:once:/bin/su --command=/usr/sbin/httpd</PRE>
<P>
'ap' must be a unique identifier. '45' refers to the runlevels for
which the command will be executed. Once is probably safer to use
than 'respawn', since if there is a mistake in this line you will see
a lot of error messages ;-(
</P>
<P><A NAME="bwd4"></A>The final part of the line '/bin/su
--command=/usr/sbin/httpd', is intended to start up Apache as a
process owned by wwwrun. It would be wise to test this command before
you put it in your <B>/etc/inittab</B>.
</P>
<H2>Search Engines</H2>
<P>If you have Apache running, and a large linux installation, then
you might want to consider implementing a search engine. S.u.S.E.
Linux provides <A HREF="http://htdig/sdsu/edu">htdig</A>, in fact to
gain full benefit from the S.u.S.E. Help System you need to use
something like htdig. The only problem is the disk space you will
need. I have a 1Gig partition devoted to documentation, this may seem
a lot to many users! I have a lot of personal documentation, program
documentation (increasingly this is HTML), all issues of Linux
Gazette, Gimp documentation, java documentation etc. This takes about
500 Meg. The database htdig uses is between 200 - 300 Meg on my
system. To update the database I need 200 - 300 Meg spare under /tmp.
Actually when I update the database I change the location of /tmp
since I do not have enough space on my root partition. Now since I
have arranged all the documentation to be available to Apache, it is
all referenced in htdig's database. If I have a question about any
aspect of linux, or any of my personal subjects, all I have to do is
formulate a suitable search pattern. I cannot adequately describe the
savings in time this has given me! In the past I would have needed to
access newsgroups to find answers to my problems. With htdig I can
avoid this 99.9% of the time! Given the low cost of hard disk space,
the fact that current program documentation is usually given as html,
that most documentation of any kind is available as html, then it
makes good sense to use Apache in conjunction with a search engine in
order to have a most efficient information retrieval system.
</P>
<P>Htdig may not be perfect, if you are used to Infoseek or lycos, it
is a bit annoying because you cannot search for a phrase e.g.
&quot;starting the x server&quot;. Rather a document is searched for
that contains all the words you enter. An advantage is that related
words are searched for as well, e.g. if you search for 'god' you can
also get results for 'gods' and 'godly'. Once you get used to htdig
it becomes an indispensable tool. The time it saves you in looking
for information is well worth the cost in terms of disk space. (on my
system the real cost is about 250 Meg, though I need another
temporary 250Meg when re-building the database).</P>
<a name="bwd5"></a><h2>SGML Support</h2>
<p>Finally I shall mention Linux's <b>SGML</b> (Standard Generalized Markup Language) support, this is not normally concidered part of web page design
since most home users will simpy want to be able to create their own
HTML home pages and have no other use for such documents.
<p>However, a great many people will want to produce documents in many
formats. The same document might need to be available for publication as a book, or as an info page as well as being available as web pages. The linux
documentation project contains many documents that are available in different formats according to users needs.
<p>SGML allows a single source to be used to produce many different kinds of
text format. The following package descriptions are taken directly from
the S.u.S.E. 6.0 distribution, though they should all be available for
other distributions:
<br><hr>
Package "sgmltool"<br><br>
<b>SGML-Tools - a text-formatting package</b><br>
SGML-Tools is a text-formatting package based on SGML (Standard Generalized Markup
Language), which allows you to produce LaTeX, HTML, GNU info, LyX, RTF, and plain ASCII (via
groff) from a single source.
<br><br>
This system is tailored for writing technical software documentation, an example of which are the Linux
HOWTO documents. It should be useful for all kinds of printed and online documentation.
<br><br>
SGML-Tools is not able to process arbitrary SGML documents; in such a case, give jade_dsl a try and
write your own DSSSL scripts (take the docbk30 package as an example).
<hr>
Package "jade_dsl"<br><br>
<b>
DSSSL-Engine for SGML documents</b><br><br>
Jade is an implementation of DSSSL (Document Style, Semantics and Specification Language);
pronounce it as "dissl" -- it rimes with whistle.
<br><br>
It has backends for SGML, RTF, MIF, TeX, and HTML.
<br><br>
The parser "nsgmls" and helper tools like "sgmlnorm", "spam", "spent", and "sx" are now included in
the separate package "sp".
<br><br>
You'll find the documentation at /usr/doc/packages/jade_dsl/.
<br><br><hr>
Package "sp"
<br><br>
<b>
SGML parser tools</b><br><br>
The tools of this package provide the possibility to manage SGML and XML documents.
<br><br>
It contains the parser `nsgmls' and the supporting programs `sgmlnorm', `spam', `spent', and `sx'. `sx' is
useful as a converting tool from SGML to XML, the comming WWW standard. You'll find the
documentation for all the programs under /usr/doc/packages/sp/.
<br><br>
<hr>
Package "sp_libs"
<br><br>
<b>Libries required for sp and jade</b><br><br><hr>
Package "gf"
<br>
<br>
<b>
A "general formatter" for SGML documents
</b><br><br>
`gf' from Gary Houston is short for "general formatter", i.e., it can work on documents which use the
ISO "general" document type definition (DTD). It can convert SGML documents conforming to a small
number of DTDs into various output formats: LaTeX, ASCII, RTF and Texinfo. However not every
output format can be generated for every DTD.
<br><br>
Apart from the general DTD, gf supports the HTML DTD used in the WWW project and Gary's Snafu
DTD. `gf' is not intended as a flexible system for hacking up a formatter for a random DTD, but as a
usable document production system for a few DTDs.
<br><br><hr>
Package "jadetex"
<br>
<br>
<b>
JadeTeX - LaTeX macros to process TeX output from Jade (jade_dsl)
</b><br><br>
With Sebastian Rahtz' macro package `jadetex' is is possible to process the output of the TeX backend
of Jade (jade_dsl). Resulting DVI files are viewable e.g., with `xdvi' or printable like any other DVI file.
<hr>
<p>
I have no real experience with SGML so I will leave the appraisal of these packages to the reader. For some people these will prove indespensible tools for
producing HTML pages.

actually had a fun time putting this months column together.&nbsp; In the
past I had been trying to find technical issues to talk about from a layman's
point of view - graphics for the masses.&nbsp; This month, I just sat down
and thought about it the way I do things.&nbsp; I play.&nbsp; I find something
new and fiddle with it.&nbsp; If it's easy to learn and I can do something
useful with it in a few minutes, I keep fiddling.&nbsp; If not, I lose
interest and come back some other time, hopefully when the application
has evolved a bit more.&nbsp;</font></font>
<p><font face="Arial,Helvetica"><font size=-1>This month I started out
by looking for video editing software for Linux.&nbsp; Now, don't get your
hopes up.&nbsp; As with many good ideas, it started in one direction and
headed slightly off center - I didn't do a write up on video editing software.&nbsp;
Instead, I looked at video viewing software.&nbsp; This is something I
thought the average user might have real use for.&nbsp; But if you're still
hoping to find out what's in store for the video editing world, don't lose
hope.&nbsp; I plan on visiting that arena soon.&nbsp; We just need the
tools that are currently available to mature a little more, and we also
need a few more options to choose from for our video editing needs.</font></font>

The Buz is a multimedia box that allows you to connect video and audio

it working on Linux requires some fairly technical understanding and willingness

<h2>
Q and A</h2>
<i><font face="Arial,Helvetica"><font size=-1>Q:&nbsp; Anyway, I've been
experimenting with BMRT and it seems much slower than POVRay, even without
using radiosity.&nbsp; Using BMRT's area lights are really slow (but probably
more accurate) compared to POV's, although the difference doesn't seem
noticeable.</font></font></i>
<p><font face="Arial,Helvetica"><font size=-1>A:&nbsp; BMRT renders with
2x2 forced oversampling by default, the adaptive oversampling it uses is
not very useful except for very high numbers of samples, because it uses
stochastic sampling.&nbsp; 2x2 oversampling is usually sufficient, but
slows it down a lot.&nbsp; As to radiosity, you can start out by setting
rsamples to 1, and most of the times the 20 or less iterations are more
than enough.&nbsp; So try</font></font>
<blockquote><tt><font size=-1>rendrib -samples 1 1 -radio 10 -rsamples
1 -res 640 480</font></tt></blockquote>
<font face="Arial,Helvetica"><font size=-1>for a test image.&nbsp; Or use
the non-standard Options</font></font>
<blockquote><tt><font size=-1>Option "radiosity" "steps" [10]</font></tt></blockquote>
<font face="Arial,Helvetica"><font size=-1>and</font></font>
<blockquote><tt><font size=-1>Option "radiosity" "minpatchsamples" [1]</font></tt></blockquote>
<font face="Arial,Helvetica"><font size=-1>If you notice radiosity artifacts
(heavy banding) on large uniformly colored areas, increase the rsamples
value (this chops each face into at least this number squared patches).&nbsp;
If your modeller supports this you may also set the subdivision on a per
object basis using the non-standard attribute</font></font>
<blockquote><tt><font size=-1>Attribute "radiosity" "patchsize" ps "elemsize"
es "minsize" ms</font></tt></blockquote>
<font face="Arial,Helvetica"><font size=-1>For details see the BMRT documentation.</font></font>

<p><i><font face="Arial,Helvetica"><font size=-1>Q.&nbsp; I have a simple
image I made with BMRT and would like to see how it would look illuminated
with radiosity.&nbsp; Does anyone have any tips on using the radiosity
settings with BMRT?</font></font></i>
<p><font face="Arial,Helvetica"><font size=-1>For simple scenes radiosity
is quite quick, and remember that it's not dependent on the image size.&nbsp;
If it takes too long you can exclude certain objects from the radiosity
calculations using the non-standard attribute</font></font>

technology (formerly computer power) and came across Graphics Muse. I'm
considering doing a second course at another college which involves web
page design (HTML/Javascript etc.) and graphic design/animation (use of
Adobe, Photoshop etc.)</font></font>
<p><font face="Arial,Helvetica"><font size=-1>In your expert opinion: is
it worth doing a structured course like this or buying a couple of web
design books and learning at home??</font></font></blockquote>
<font face="Arial,Helvetica"><font size=-1><b><font color="#993300">'Muse</font></b>:&nbsp;
This is highly dependent on your own motivation and learning habits.&nbsp;
I, personally, learn much more on my own than in a class, but often take
a class when just starting a new topic to get me pointed in the right direction
(like photography, which I just got into recently).</font></font>
<p><font face="Arial,Helvetica"><font size=-1>HTML is easy enough to learn
on your own - there really isn't that much too it.&nbsp; If you need to
learn a slew of specific applications it often helps to take a class (it's
often harder to learn to use the applications than just writing the HTML
yourself).&nbsp; Java is a language unto itself and I'm certain a structured
course would help.&nbsp; Design animation as a class covers a very broad
range of topics - colors, structures, paint and animation techniques, procedural
animation, etc.&nbsp; That's not a class, really - it's a whole degree.&nbsp;
Using Photoshop or some other specific tool is like what I said previously,
it helps to take a class if the tool is sufficiently complex.&nbsp; I don't
think Photoshop is hard to learn (the Gimp is easier - you could always
buy my book on how to use it, of course).&nbsp; But learning what buttons
do what functions in only a small part of the job.&nbsp; The bigger part
is how to use those buttons creatively to produce interesting effects,
sometimes to the point of being able to reproduce the effect quickly (like
drop shadows for logos, which is a very common requirement from clients)
and in the same manner each time.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>If you're just learning web
design for fun, or even for your business, and are confident in your own
ability to teach yourself new topics, then skip the class.&nbsp; But if,
like me, you find a little push in the right direction helps, then take
the structured class.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>Of course, if it makes any
difference, I've never taken any classes on HTML or computer graphics.&nbsp;
It's all self taught (except for some minor OpenGL experience, but I never
really used what I learned).</font></font>
<p><font face="Arial,Helvetica"><font size=-1>Hope that helps.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>Now, on the subject of image
resolution and printing, I found this post from Brian Reynolds on one of
the Gimp mailing lists:</font></font>
<blockquote><font face="Arial,Helvetica"><font size=-1>David Fokos has
written a very good paper on creating half-tone digital negatives for contact
printing.&nbsp; You can find it at Bostick &amp; Sullivan's web site at:</font></font>
<br><font face="Arial,Helvetica"><font size=-1><a href="http://www.bostick-sullivan.com/Technical%20papers/Digital%20Info/Dave_Fokos/davetech.htm">http://www.bostick-sullivan.com/Technical%20papers/Digital%20Info/Dave_Fokos/davetech.htm</a></font></font>
<p><font face="Arial,Helvetica"><font size=-1>Besides discussing all the
details about making negatives for contact printing, this paper has a very
good explanation of the resolution metrics (dpi, ppi, lpi) for the various
types of equipment used for digital input and output and how they relate
to each other.&nbsp; The paper assumes you are using Photoshop, but gives
general enough descriptions that you aren't tied to it (as opposed to another
book on digital negatives that assumes Photoshop is the only software available).</font></font>

<font face="Arial,Helvetica"><font size=-1>I read the paper and Brian is
right - you can apply the digital techniques David discusses to the Gimp
just fine.&nbsp; You might need a bit of background on photography for
this paper, but it's well worth the read.</font></font>

<h2>
Interactive Management of Image Maps</h2>
<font face="Arial,Helvetica"><font size=-1>One of the tools lacking from
the Linux arsenal these days is a really good interactive Web page builder.&nbsp;
I use Netscape Composer for all my pages, but this lacks any sort of integrated
graphics editor.&nbsp; You can configure it to launch an external editor,
however, and this is where the ever popular <a href="http://www.gimp.org">Gimp</a>
comes in.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>The Gimp is, of course, the
best raster image editor on Linux.&nbsp; Not only does it have support
for many different effects and filters, it also has a dynamically extendable
interface through the use of plug-ins.&nbsp; One of the latest plug-ins
to gain popular attention is the <a href="http://home-2.consunet.nl/~cb007736/imagemap.html">Image
Map</a> plug-in from <a href="mailto:lpeek.mrijk@consunet.nl">Maurits Rijk</a>.</font></font>

</td>

</table>
<font face="Arial,Helvetica"><font size=-1>Image Maps, for those unfamiliar
with their use, are an HTML construct that allows an Web page author to
specify regions within a single image to be used as links to different
URLs.&nbsp; Regions can be specified using rectangular, oval and polygonal
coordinates.&nbsp; Both server and client side maps are possible, although
client-side image maps are the more popular of the two types.&nbsp; This
column uses a client-side image map for navigation at the top of the page
(upper left corner of the page, just below the Graphics Muse logo).&nbsp;
By providing a method of mapping the single image into multiple links,
image maps reduce the overhead that multiple images positioned using tables
would require.</font></font>
<p><font size=-1><font face="Arial,Helvetica">The current version of the
Image Map plug-in is 1.1.1.&nbsp; This version includes recent support
for HTML <i>onBlur</i> and <i>onFocus</i> tags.&nbsp; Although the interface
is fairly well designed, the program currently provides no documentation.&nbsp;
Building from source (which is how this plug-in is distributed) is simple
enough:&nbsp; just unpack it and type <i>make</i>.&nbsp; There shouldn't
be any editing of Makefiles or other configuration files necessary.&nbsp;
After compiling you can either do a <i>make install</i> or simply copy
the binary (named <b><font color="#CC6600">imagemap</font></b>) to your
</font><tt>$HOME/.gimp/plug-ins
</tt><font face="Arial,Helvetica">directory
and restart Gimp.&nbsp; Once installed, the plug-in can be accessed via
the <i>Filters->Misc</i> submenu of the Image Window menu.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>The interface consists of
a scrollable window on the left and the set of URL links on the right.&nbsp;
The scrolled window is a full size copy of the original image.&nbsp; Two
menu bars are provided - one using traditional pull down text menus and
the other an icon based version of the same features.&nbsp; An additional
icon based menu of region shapes (rectangular, oval, polygonal and so forth)
runs along the left side.&nbsp; The icon menus are all detachable - you
can click on the rough edged left side of each and drag it out of the main
window, although what advantage this might provide I don't know.</font></font>

</table>
<font face="Arial,Helvetica"><font size=-1>In order to start specifying
regions for the image map, you might first consider turning on the grid
lines.&nbsp; This can be done quickly using the Grid icon in the icon menu
bar, but you'll probably also want to adjust the granularity of the grid.&nbsp;
This can only be done by selecting Goodies->Grid Settings from the text
menus.&nbsp; This will open a dialog box where you can specify the width
and height of the grid boxes, the method for displaying the grids (lines,
crosses or hidden), an offset from the upper left corner in which to begin
the grid and, most importantly, whether region shapes are snapped to grid
intersections.&nbsp; This last item is what will make creating your image
maps rather quick and painless.</font></font>

<h2>
<b><font face="Arial,Helvetica"><font size=+1>Linux Video Choices: A review
of Xanim, MainView, MpegTV and RealVideo.</font></font></b></h2>
<font face="Arial,Helvetica"><font size=-1>I don't do much video work on
Linux yet.&nbsp; I have a sufficiently fast box for it, I just haven't
had much more than a passing interest in it since there aren't many video
editing tools available yet.&nbsp; Still, viewing animation's (in something
other than GIF format on a browser) or streaming video has become an important
part of the Internet in the past few months.&nbsp; So I thought I should
at least take a look at what tools are available from a viewers perspective.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>Now, there are a probably
a couple dozen projects underway for viewing video and animations on Linux.&nbsp;
I can't review all of these, there just isn't enough time in the day to
do them justice.&nbsp; So I've chosen four viewers that I think represent
varying aspects of digital video as well as varying support for different
video formats.&nbsp; The four tools are <b><font color="#993300">Xanim</font></b>
by Mark Podlipec, <b><font color="#993300">MainView</font></b> by MainConcept,
<b><font color="#993300">MpegTV</font></b>
by MpegTV, and <b><font color="#993300">RealVideo</font></b> from RealNetworks.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>In order to test these I
decided to download a series of RealVideo, MPEG, and Quicktime files, both
with and without audio, and see how each tool that supports them performed.&nbsp;
For RealVideo and MpegTV, I used appropriate URLs.&nbsp; The test system
was configured with 256Mb of memory using a <a href="#truecolor">TrueColor
visual </a>under the Xi Graphics Accelerated X server with a Matrox Mystique
4Mb video card and the commercial Open Sound System drivers for a Generic
MAD16 Pro (OPTi 82C929) soundcard.&nbsp; For animation's or streaming video/audio
which were used in these tests and for which I know a URL, I have provided
links to the test files.&nbsp; I can't post the video files here since
the Linux Gazette (which is the main location for the Muse column) gets
distributed to a lot of places that wouldn't be happy downloading 2Mb+
video files.</font></font>
<p><b><font face="Arial,Helvetica">A note about file types</font></b>
<p><font face="Arial,Helvetica"><font size=-1>If you're not familiar with
the codec types, just look for animation files with suffices like .mov
and .anim( both are versions of Quicktime, I believe), .fli (FLI/FLC),
.ram, .rm and .rv (RealVideo files), and .mpg (MPEG animation's).</font></font>
<p><b><font face="Arial,Helvetica"><a href="http://xanim.va.pubnix.com/home.html">Xanim</a></font></b>
<br><font face="Arial,Helvetica"><font size=-1>Latest version: 2.80.1</font></font>
<p><font face="Arial,Helvetica"><font size=-1>Long before the others arrived
on the scene, Mark Podlipec's xanim was serving up video files to the masses.&nbsp;
Supporting AVI, Quicktime, FLI/FLC, Amiga, and JFIF file formats along
with GIF and DL Animation's as well as a number of audio formats, the X
Windows System based xanim can play just about any popular animation files
you might find on the Internet.</font></font>

</table>
<font face="Arial,Helvetica"><font size=-1>Xanim is provided in source
format for the main engine, with binary dynamically loadable libraries
(DLLs) provided for various codecs for which the copyright owner would
only provide information if Mark signed an NDA.&nbsp; In a sense, I think
Mark's solution to the proprietary vs. open problem is probably not a bad
compromise.&nbsp; In any case, the source is portable to many Unix (and
other) platforms.&nbsp; Building the source is fairly easy for Linux systems.&nbsp;
Unfortunately the package doesn't support autoconf&nbsp; based compilation,
but I'm not one to complain much about that (considering my own XNotesPlus
doesn't support it either - who has time to learn all these tools?).&nbsp;
Mark provides a build based around imake, which isn't too bad a substitute
for autoconf.&nbsp; The Imakefile only needs one modification for building
on Linux - in section IVb add this line:</font></font>
<blockquote><tt><font size=-1>EXTRA_DEFINES = -I/usr/X11R6/include/X11</font></tt></blockquote>
<font size=-1><font face="Arial,Helvetica">This is necessary, even though
the Imakefile says it shouldn't be required, because Mark doesn't prefix
his use of the X header files with "X11/&lt;header file>" but the standard
imake templates assume that applications do so.&nbsp; Since Mark apparently
does his builds on Linux too, the rest of the Imakefile should probably
work just fine as it is.&nbsp; You then run "</font><tt>xmkmf; make xanim</tt><font face="Arial,Helvetica">"
to build the program.&nbsp; Then just copy it to an appropriate directory,
such as </font><tt>/usr/local/bin</tt><font face="Arial,Helvetica">.&nbsp;
Installation, from build to running my first animation, took about 10 minutes.</font></font>
<p><font size=-1><font face="Arial,Helvetica">The interface for xanim is
rather small, but it supports starting, stopping, rewinding and audio levels.&nbsp;
You can step through a video by clicking various mouse buttons in the display
window.&nbsp; Most of the options supported by xanim are accessible only
from the command line.&nbsp; You can find what options are available using
the traditional </font><tt>--help</tt><font face="Arial,Helvetica"> command
line option.&nbsp; There is a remote interface available that allows external
programs to control xanim and I believe there are GTK, TK and KDE based
front ends to xanim now, although I didn't specifically look for them.&nbsp;
Note that there is no built-in help facility to xanim.&nbsp; You'll need
to read the documentation or visit the Web site for details.&nbsp; But
for most animation's, especially on systems with TrueColor visuals (i.e.
16.7 million color displays), you simply run "</font><tt>xanim &lt;filename></tt><font face="Arial,Helvetica">".&nbsp;
Pretty straight forward, really.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>Xanim played all 14 of the
videos I tried with absolutely no problem.&nbsp; I tested Quicktime, MPEG,
FLI and IFF animation's.&nbsp; There was little jitter or no obviously
skipped frames and the sound was perfectly synchronized with the animation's
which came with audio (which, as it turns out, was just the Quicktime files).&nbsp;
Tests were run in both TrueColor and 256 color modes.&nbsp; Xanim had no
problems mapping the full color videos to the lower bit planes.&nbsp; In
fact, it did a better job of doing it than I could using various command
line color related options.&nbsp; By default xanim will loop through the
animation indefinitely.&nbsp; You can change this behavior using command
line options.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>By supporting dynamic loading
of video codecs, Mark has made it easier for end users to add support for
any new codecs that might come along.&nbsp; Now you can simply download
the appropriate binary codec from his site, unpack it, and restart xanim.&nbsp;&nbsp;
Recompilation is no longer necessary.&nbsp; Despite it's apparent visible
simplicity, xanim is still the best all around video player for Linux.</font></font>
<p><b><font face="Arial,Helvetica"><a href="http://www.mainconcept.com">MainView</a></font></b>
<br><font face="Arial,Helvetica"><font size=-1>Version 2.06</font></font>
<p><font face="Arial,Helvetica"><font size=-1>In trying to figure out a
topic for this month's Musings, I started to look around for video editing
software.&nbsp; I'd heard a few packages were available, but had never
tried any of them.&nbsp; One package I did run across was a new commercial
package (currently freely available as a beta distribution) from a German
company called MainConcept.&nbsp; This package included a video display
tool called MainView.</font></font>

<p><font face="Arial,Helvetica"><font size=-1>MainView is actually an external
viewer application to the larger MainActor Video Editing system.&nbsp;
It can, however, be run independently of MainActor.&nbsp; The interface
is even more sparse than xanim's, but doesn't appear as cramped.&nbsp;
Run time options can be accessed through a menu which you can open by right
button clicking with your mouse over the animation window.&nbsp; Options
include changing the speed of the animation and various audio options.&nbsp;
Audio, unfortunately, didn't work at all on any of the animation's I tried.&nbsp;
It always played very loud and completely distorted audio.&nbsp; I ended
up turning audio off after testing it on all the files for audio support
so I could continue testing video playback.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>Video support is much better
than audio, fortunately.&nbsp; All 14 of the animation's I tried played
flawlessly under a TrueColor display.&nbsp; When I started MainView the
very first time, I noticed that it complained about requiring the XFree86
DGA (Direct Graphics Extension) extension, but still started anyway.&nbsp;
The extension, it turns out, is only needed if you want to run in full
screen mode.&nbsp; As long as you're not trying to do that, the video portion
of MainView works fairly well.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>One nice feature of MainView
is that it remembers the last directory you were in between sessions.&nbsp;
I like this because I can launch MainView from my FVWM2 GoodStuff bar and
have it be in a directory where I save animation files.&nbsp; MainView
will start by providing a file browser window from which you can select
an animation to view.&nbsp; It then closes the file browser and starts
the video playback window.&nbsp; There doesn't appear to be a way to return
to the file browser, however.&nbsp; That sure would make it easier to browse
through multiple video files without having to restart MainView each time.&nbsp;
MainView also doesn't automatically loop through videos.&nbsp; In fact,
I couldn't find a way from within MainView itself to get a video to loop.&nbsp;
MainActor does allow you to set a repeat count, but not an infinite loop.</font></font>

annoying "please register" window common for shareware applications.&nbsp;
Personally, this doesn't bug me much since I don't have any problem with
people trying to sell their software.&nbsp; If it's worth it, I pay for
it.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>Unfortunately for MpegTV,
this dialog did pose a problem.&nbsp; Half way through the Star Wars trailer
(which I downloaded from their site as part of my testing) the Registration
dialog popped up.&nbsp; At that point the sound quit and the main control
window wasn't redrawn and no longer accepted user input.&nbsp; The video,
however, kept playing.&nbsp; The only way to exit the program after this
was to use "kill -9" on the mtv and mtvp processes.&nbsp; Since I had to
run the program multiple times to try to get screen shots and try various
features, this bug became a real annoyance.&nbsp; I'm hoping that the registered
version doesn't do this (since you should never see the registration screen).</font></font>
<p><font face="Arial,Helvetica"><font size=-1>SDL - <a href="http://www.devolution.com/~slouken/SDL/">Simple
Direct Media Layer</a> -&nbsp; is the same library used by Loki for their
port of Civilization: Call To Power.&nbsp; It provides a layer between
X applications and various low level multimedia API's, including XFree86's
DGA extension.&nbsp; I suspect you'll be seeing this library being used,
and required by, quite a few applications in the future.&nbsp; For MpegTV,
SDL is only required to run MpegTV in full screen mode.&nbsp; One problem
I had with this was that the SDL installation tool installs the library
under /usr/local/lib by default (you can change this during the installation
process).&nbsp; MpegTV requires that the library be installed under /usr/X11R6/lib.&nbsp;
I installed the library under /usr/local/lib and added symbolic links under
/usr/X11R6/lib.&nbsp; This should have worked, but for some reason MpegTV
failed to load the libraries.&nbsp; As far as I can tell, there is nothing
wrong with the symbolic links so I suspect that the library
<b><u>must</u></b>
really be under /usr/X11R6/lib in order to work with MpegTV.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>the company's Web site offered
two test animation's, a short animation of bouncing boxes and an old Star
Wars trailer.&nbsp; Both of these played just fine.&nbsp; There is also
a link to a site with more links to MPEG animation's on the net.&nbsp;
I bounced around a few of those but couldn't find anything more interesting
than the 3 other MPEG animation's I already had.&nbsp; MpegTV played them
all just fine (if you ignore the Registration dialog problem).&nbsp; Additionally,
MpegTV can also play Video CDs, such as the video portion of music CDs.&nbsp;
It doesn't play DVD, however.&nbsp; Although my RH 5.2 system appears to
have the VCD patch applied, and xreadvcd does appear to read the video
cd contents, I couldn't get MpegTV to read the CD nor could I get xreadvcd
to write the MPEG stream to a file.&nbsp; There is something wrong with
my kernel configuration, apparently, so I couldn't really test the Video
CD support in MpegTV.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>Interestingly enough, after
downloading the two test MPEG files from the MpegTV site and trying them
with mtv, I then went back and tried them with xanim.&nbsp; I couldn't
play either of them correctly with xanim.&nbsp; I then tried some of the
other mpg files I had used with xanim under mtv.&nbsp; They all played
about the same except for one - monopoly.mpg.&nbsp; Under xanim this played
rather slow, with distinct stoppage between frames.&nbsp; Under mtv this
played just fine.&nbsp; The frames flowed by seamlessly.&nbsp; So, mtv
appears to deal with MPEG files better than xanim, although mtv appears
to have some nasty bugs, at least in the unregistered version.</font></font>
<p><font size=-1><font face="Arial,Helvetica">MpegTV will play MPEG streams
direct from the Internet if you supply a URL on the command line or through
the </font><tt>Play From URL </tt><font face="Arial,Helvetica">option from
the File menu in the control window.&nbsp; I tried this with one site but
found the stream to be too slow to play interactively.&nbsp; After the
20 minute download, which did play while it was being downloaded even though
it looked like only one frame every so often was playing, I tried to replay
it and save it.&nbsp; I could do neither.&nbsp; I don't know if this is
a limitation in the unregistered version or not, however.</font></font>

G2 Beta version</a></font></font>
<p><font face="Arial,Helvetica"><font size=-1>One of my favorite tools
to be ported to Linux is the RealVideo G2 player from RealNetworks.&nbsp;
While working for Samsung in Dallas, and forced to use an NT box for email,
I got hooked watching and listening to Bloomberg TV financial reports.&nbsp;
I was able to do this only because I was stuck with that NT box (which
sat to one side and collected dust most of the time) and G2 didn't run
on my Solaris box.&nbsp; Now that I'm working from home, I'm thrilled to
be able to view this same content from my Linux box.</font></font>

<br><b><font face="Arial,Helvetica">(Synchronized Multimedia Integration

</td>
</tr>
</table>
<p><font size=-1><font face="Arial,Helvetica">The G2 player can play any
of the streaming video and audio formats from RealNetworks.&nbsp; This
includes the older .ram and .rm audio files as well as the new Synchronized
Multimedia Integration Language - SMIL, yet another of the HTML-style formatting
languages - files, suffixed with </font><b><tt>.smi</tt></b><font face="Arial,Helvetica">.&nbsp;
It doesn't play MPEG or any of the formats the other players support, however.&nbsp;
So you need to find sites that support the RealNetworks formats.&nbsp;&nbsp;
Fortunately, these sites abound on the Internet.&nbsp; RealNetworks was
one of the first to provide a usable streaming media format for the Internet
and it caught on very fast.&nbsp; Many news sites support RealVideo these
days.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>The Linux version is still
in beta, at least to my knowledge.&nbsp; I've had no serious problems with
it although sometimes the video window can get visual artifacts when you
switch sites.&nbsp; It also had a few problems with refreshing the video
window when another window had partially hidden the G2 player, and then
the other window was moved away.&nbsp; These problems only happened with
static parts of the video window - any animation's forced window updates
and so they appeared to work just fine.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>Playing of the streams has
been pretty good.&nbsp; I think I have more problems with network delays
than with playing the streams.&nbsp; The G2 player comes with a host of
options to configure the player for best performance.&nbsp; It can work
behind firewalls if you're network administrator permits passing the right
port numbers.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>The player itself is made
up of a primary video display window surrounded by associated controls.&nbsp;
The NT version includes a scrolling icon-based playlist on the left of
the video window but the Linux version lacks this currently.&nbsp; I don't
think there are any serious technical reason they can't add it in the future,
though.&nbsp; Information about the clip currently playing can be scrolled
through the Clip Info window, or this can be disabled to help increase
performance just a bit.&nbsp; The audio support is very good - RealNetworks
chose to allow skipped video frames in exchange for a fluid audio performance.&nbsp;
I find that appealing as I often just listen to the streams while doing
other work.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>Streaming video is still
a jumpy affair.&nbsp; You don't get the smooth frame-by-frame animation's
you get when playing an MPEG or Quicktime file directly from your hard
disk.&nbsp; But the format does support moving anywhere within the stream
at any time.&nbsp; I can jump to the middle and pick up playing from that
point if I choose.&nbsp; Or I can rewind or start over at any point within
the currently playing stream.&nbsp; And I don't have to wait for the entire
file to download in order to do this.&nbsp; I still think streaming audio
is a better media for this technology due to general limitations in bandwidth
to the user, but once we all have higher speed connections, streaming video
will offer choices that TV and cable never could.</font></font>
<p><b><font face="Arial,Helvetica">Other tools</font></b>
<p><font face="Arial,Helvetica"><font size=-1>One other player I tried
was <a href="http://www.freeyellow.com/members4/heroine/">XMovie</a>.&nbsp;
This is a program that runs off of a library built to run Quicktime movies.&nbsp;
It's part of a series of tools that include another video editor called
BCast2000.&nbsp; However, there are licensing limitations with Quicktime
that XMovie can't get around.&nbsp; I don't know if that was the reason
or not, but XMovie couldn't play any of the animation's I tried.&nbsp;
Whatever codecs it supports, it's not the ones being used in the video
files I found on the Internet.</font></font>
<p><b><font face="Arial,Helvetica">Places to find video files online</font></b>
<p><font face="Arial,Helvetica"><font size=-1>You can always check many
of the entertainment sites online, such as <a href="http://www.eonline.com">E!
Online</a>, and <a href="http://www.comcentral.com/download/index.shtml">Comedy
Central's</a> download site.&nbsp; Additionally, you can find clips and
links to other online sources of video files at <a href="http://www.uslink.net/~edgerton/index.html">Jesse's
Movies</a>, and <a href="http://dir.yahoo.com/Entertainment/Movies_and_Film/Multimedia/Video_Clips/">Yahoo!'s
set of movie clip links.</a>&nbsp; Streaming MPEG and MPEG files sites
can be found at <a href="http://www.mpeg.org/MPEG/bitstreams.html">MPEG.org's
MPEG Bitstreams page</a>.&nbsp; RealVideo clips can be found at the
<a href="http://www.real.com/showcase/realplayer/index.html">RealVideo
Showcase</a> site and a their <a href="http://realguide.real.com/">Real
Guide</a> site.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>Keep in mind that playing
movies like this doesn't require huge amounts of hardware - a 32Mb Pentium
133 should work just fine, although some animation's may play a little
slow and audio might not sync all that well.&nbsp; But you certainly don't
need the 256Mb of memory I used, nor do you need the latest CPU.&nbsp;
And you certainly don't need a 3D accelerated video card.&nbsp; These animation's
are basically all just a series of individual raster images played very
fast.&nbsp; It's like using a flip book of pictures - the faster you can
flip through the pages, the faster the animation appears to work.&nbsp;
Except on computers and with the right player, you have more control over
the speed.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>I have to admit, I'm still
a big fan of xanim over any of the other players I've tried.&nbsp; For
95% of the animation's out there it's just the right tool for the job.&nbsp;
But it doesn't, to my knowledge, support streaming video/audio.&nbsp; Since
I don't have cable television anymore (what a waste of money that is),
I get my news and information online.&nbsp; I find myself listening and
even watching streaming audio and video with RealVideo quite often these
days.&nbsp; Since the information streams, I can leave it running while
I work and just listen to the bits and pieces of what ever interests me.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>Like whether or not my shares
of Disney are ever going to go back into positive territory.&nbsp; Maybe
if they released all their films as streaming MPEGs....</font></font>
<p><font face="Arial,Helvetica"><font size=-1>Since I've always been a
fan of visual media, I find the opportunity to build my own webcasts rather
enticing.&nbsp; Streaming video and audio are the best future for online
video because they don't require the user to download the entire file to
play it.&nbsp; At some point in the future, I hope to be able to put together
some live interviews for webcasting, but I have to investigate what that
will cost and where it can be hosted.&nbsp; In the mean time, at least
I have the right tools to view other webcasts and online video.</font></font>

to contact him about using it....hope there's no problem.&nbsp; In the

my mods already).&nbsp; You can take EPS to Tk using these tools:</font></font>

<p><font face="Arial,Helvetica"><font size=-1>Another thing you might want
to try (though people question its practical implications) is to download
the Tcl/Tk plugin from <a href="http://www.scriptics.com">www.scriptics.com

install it into a Netscape browser under Linux.&nbsp; Then edit the plugin.cfg
file as indicated in the documentation to allow you to load a tclet from
<a href="http://www.ntlug.org">www.ntlug.org
</a>and
you can then execute the demo showing a document being retrieved off the
web for editing inside a web browser.&nbsp; It can be saved to any local
disk (which could be a samba mounted area for example).&nbsp; (there are
some Netscape bugs which prevent "saving" from working real well)</font></font>

works similarly, except that a double click is required to end the shape
and open the attributes dialog.&nbsp; Additionally, with polygonal shapes
a left mouse button click will anchor a new vertices for the shape.&nbsp;
A right mouse button click will delete the vertices in reverse order.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>To edit the shapes, click
on their URLs in the Selection window or click on the shapes outline while
the Select Existing Area button (the button with the arrow along the left
side of the dialog window) is enabled.&nbsp; Note that when you edit the
shapes size by dragging one of the handles on the shapes outline that the
snap to grid function is no longer in effect.&nbsp; I don't know if this
was intentional or not, however.&nbsp; Don't be suprised to see this change
to match the current grid settings in later releases.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>Once you've set the URLs

<font face="Arial,Helvetica"><font size=-1>Notice that the source images
URL is taken to be the path to the image I've opened in the Gimp.&nbsp;
I looked around the plug-in but couldn't find a way to change this.&nbsp;
You apparently have to edit the HTML code manually.&nbsp; There is an option
to set a default URL, using the Info icon, but you can't change the source
reference for the image.&nbsp; One you have this HTML&nbsp;output to a
file you'll need to find some way of importing it into your real HTML&nbsp;file.&nbsp;
The Image Map plug-in does not currently allow you to place this code directly
into an existing HTML file.</font></font>
<p><font face="Arial,Helvetica"><font size=-1>Unfortunately, I found, along
with quite a few bugs with the 1.1.1 release, that the Image Map plug-in
doesn't do many of the things I would like.&nbsp; First, the polygonal
area tool is really difficult to use.&nbsp; For some reason, it won't accept
my double clicks to end a polygon shape definition unless I double click
and don't move my mouse for a split second afterwards.&nbsp; If I double
click and move too quickly I get all sorts of line drawings from the last
vertices created to the current mouse location.&nbsp; It looks something
like a star burst shape.&nbsp; In any case, it's not what was expected.&nbsp;
The unwanted star burst design will go away if you cover and then uncover
the Image Map window with another window (forcing a window update for the
Image Map plug-in).&nbsp; However, getting out of that mode seems to require
backing completely out of the polygon by right mouse clicking until all
vertices have been removed.&nbsp; At this point, the extra line drawing
seems to stop.</font></font><font face="Arial,Helvetica"><font size=-1></font></font>
<p><font face="Arial,Helvetica"><font size=-1>Another nit pick of mine
is that the up and down buttons for URLs moves the selected item to the
top or bottom of the list, not up or down one list item.&nbsp; I feel a
little like I'm playing the Towers of Hanoi trying to arrange the URLs.&nbsp;
And I can't specify the path to the image source without hand editing the
saved HTML that the plug-in outputs to file.</font></font><font face="Arial,Helvetica"><font size=-1></font></font>
<p><font face="Arial,Helvetica"><font size=-1>Zoom takes a little while
to work - it zooms the whole image and doesn't appear to let you specify
the area to focus in on.&nbsp; I suspect it uses it's own zooming algorithm
and not the Gimp's since the Gimp's zoom is considerably faster.&nbsp;
Or maybe it just takes longer to recompute image map area shapes.&nbsp;
I also don't like the fact that changes to width, height or other shape
attributes don't automatically update the display.&nbsp; I think automatic
updates should probably be a user configurable preference.</font></font><font face="Arial,Helvetica"><font size=-1></font></font>
<p><font face="Arial,Helvetica"><font size=-1>As for bugs, there were a
number that were difficult to recreate.&nbsp; Aside from the problem with
the polygons and double clicking, I&nbsp;noticed at one point that the
height of my first rectangular selection, as displayed in the settings
dialog, was only 1 pixel high.&nbsp; But most of the bugs I found were
minor and self correcting.&nbsp; None seemed to cause the final HTML&nbsp;output
to be corrupted in any way.</font></font><font face="Arial,Helvetica"><font size=-1></font></font>
<p><font face="Arial,Helvetica"><font size=-1>Although I might prefer changes
to certain aspects of the interface, I find Maurits' Image Map plug-in
for the Gimp to be stable, easy to use and produces syntactically correct
HTML.&nbsp; If you do a fair amount of image map work, or even if you'd
just like to create one just for grins, you owe it to yourself to take
a look at this plug-in.&nbsp; It may just easy your life just a bit.</font></font>

<EM>ESR goes to Microsoft ... and lives to tell about it!</EM>
<p>It was not a normal day here in Seattle. Eggs were balancing on
end. The city was shrouded in a most un-summerlike mist and fog. And
ESR was speaking at Microsoft.
<p>That's right. Eric S. Raymond was the invited guest of Microsoft
Corporation, and gave a speech to their research group. June 21st was
indeed a freaky Summer Solstice day here in the Northwest.
<p>Eric went into the belly of the beast ... and lives to tell about
it. He was kind enough to share his impressions of what went on, via
this e-mail interview.
<p><i><STRONG>Q:</STRONG> Can you give us a general overview of how and why you came to
be invited to speak at Microsoft's Redmond campus?</i>
<p><STRONG>A:</STRONG> I was invited there by a member of one of Microsoft's research
groups that I met at PC Forum 99. She seemed OK, and offered an
inducement far more interesting than a speaker's fee (about which more
below) so I accepted.
<p><i><STRONG>Q:</STRONG> Were you offered a tour of the campus, and/or were you
introduced to any of the &quot;big name&quot; executives of Microsoft?</i>
<p><STRONG>A:</STRONG> No campus tour, no big names. Though I suppose they might have been
watching the video feed....
<p><i><STRONG>Q:</STRONG> What was the venue like, and how many people showed up for the
event?</i>
<p><STRONG>A:</STRONG> It was a small auditorium. It looked to me like about 200 people
showed up; it was standing room only, with people stacked against the
walls and sitting in the aisles.
<p><i><STRONG>Q:</STRONG> What were the general themes of your speech/presentation? How
were they received? </i>
<p><STRONG>A:</STRONG> All the usual ones for anyone who has heard my talks. Better
reliability through peer review, how Linux beat Brook's Law, open-source
project ownership customs and the reputation incentive, the eight
open-source business models, scaling and complexity effects.
<p><i><STRONG>Q:</STRONG> A confidential informant tells me the event was broadcast to
all 20,000-plus Redmond employees of Microsoft over their internal
network.
This same informant also says a fair percentage of those in actual
attendance became somewhat belligerent towards you and your Open Source
message. Is this true? If so, would you mind elaborating on which parts
of your presentation they took issue with? For example, were they most
perturbed at the insinuation that Open Source products like Linux are
better in the long run than proprietary systems like MS Windows 2000?</i>
<p><STRONG>A:</STRONG> Yes, there were a few belligerent types. Typical was one guy who
observed that Oracle has a partial open-source strategy, then
triumphantly announced that Microsoft's earnings per employee are
several times Oracle's, as though this were a conclusive argument on the
technical issues.
<p>It was kind of amusing, really, fielding brickbats from
testosterone-pumped twentysomethings for whom money and Microsoft's
survival are so central that they have trouble grokking that anyone
can truly think outside that box. On some subjects, their brains just
shut down -- the style reminded me a lot of the anonymous cowards on
Slashdot.
<p>One of the Microsoft people, who knew the faces in the audience,
observed to me afterwards that the people from the NT 2000 development
group were particularly defensive. So, yes, I think my insinuations
were perturbing.
<p><i><STRONG>Q:</STRONG> Did you notice an overall "mood" or general level of
receptivity held by attendees towards what you had to say?</i>
<p><STRONG>A:</STRONG> More positive than I had expected. The flamers were a minority, and
they occasionally got stepped on by other audience members.
<p><i><STRONG>Q:</STRONG> Anything else interesting to report from your Microsoft
visit?</i>
<p><STRONG>A:</STRONG> Yes. One of its co-authors gave me an autographed copy of
&quot;The Unix-Hater's Handbook&quot; :-) But that doesn't quite mean
what you think it does -- I had been one of the manuscript reviewers.
<p><i><STRONG>Q:</STRONG> Of course, many may gather that perhaps the most fun and
exciting aspect of your visit was your dinner with science/speculative
fiction authors Greg Bear and Neal Stephenson. Was that as fun as it
sounds to the rest of us?</i>
<p><STRONG>A:</STRONG> Sure was. Those dinner plans were what seduced me into going to
Redmond, and I wasn't disappointed. George Dyson (author of &quot;Darwin
Among the Machines&quot;, and Esther Dyson's brother) was there too. We
spoke
of many things; science fiction and AI and Turing-computability and
cryptography. Oh, and Neal solicited my advice on the proper firearm
for dealing with cougars while hiking with his kids.

<h2>Update!</h2>
<p><a href="http://weber.u.washington.edu/~gfish">Matthew Dockrey</a>
offers his eyewitness account of ESR's Microsoft speech.
<p>Monday morning, a friend of mine at Microsoft mentioned he got a
mailing about the ESR presentation and thought he would swing by. Being
an opportunist, I convinced him to sneak me in. Luckily, they weren't
checking badges at any point. Considering how much they value trade
secrets, their security is really quite lax.
<p>The presentation was in a conference room in Building 31 (Research).
It was far too small for the turnout, although my friend reminded me that
this was supposed to be for just the research group. Getting there 20
minutes late after missing the bus, we were left trying to catch a peek
through the crowd. There was a live video feed as well, and we ended up
watching the first half from 10 meters down the hall on someone's
computer.
<p>The audience was a very odd mix. Most of the people seemed very
serious and were even taking notes. I did notice someone with a KMFMS
t-shirt, though. Some were very obviously hostile towards the Open
Source approach, but not all. (Not everyone who works at Microsoft
actually uses their products at home, remember.) On the way to the
presentation, I saw an office with <i>Linux Journal</i>s and
O'Reilly Linux manuals laying about, so not everyone there is ignoring us.
<p>Overall, it was a good presentation. I was generally impressed with
ESR's skills as an orator. He spent most of the time giving a
sociological explanation for why OSS works, or exists at all. Nothing
all that revolutionary (to us): Open Source is a variant of the
&quot;gift-culture&quot; that often forms when groups of people are not
greatly
bounded by material limitations (such as coastal Pacific Native
Americans and really rich people) and therefore take to giving away
wealth as demonstration of their worth. He also detailed the culture of
Open Source projects, the general patterns and taboos (a project is
owned by someone; you don't fork the project unless you have very good
reasons, etc.) and compared this to territoriality, especially the way we
view land ownership. You can homestead land (start a project), buy
land (have the previous project owner give it to you) or squat on unused
land (take over a long-idle project).
<p>I felt the presentation lost a bit of its focus when he moved from
the abstract sociological viewpoint to actual justification for Open
Source in a business model. I think this was largely because he based
some of his arguments on sweeping claims about OSS being generally
better than proprietary, and the audience challenged this. His point
would probably have been better made without being quite so
confrontational here.
<p>He did make a very good point that 95% of software development is for
internal use only, although there was an amusing moment when his survey of
this particular audience did not reflect this. He also touched on the
fact that most revenue from software is based in support, not the
original sale. He mentioned what happened with Zope, but failed to
pursue it. Of all the business arguments for OSS (and I admit I lean
towards RMS's moralism over ESR's practicality), this seems to be the
most relevant.
<p>Overall, it was a very good presentation, and the audience seemed
generally receptive to his ideas. There were some good-natured laughs on
both sides, such as ESR admitting that most of the gift cultures had been
destroyed by disease, or ESR stating a desire to live in a world &quot;where
software doesn't suck&quot; as a valid reason for working on an OSS project. I
found it particularly amusing when, halfway through the presentation, someone
started handing out freshly printed copies of Sunday's <a
href="http://www.userfriendly.org/cartoons/archives/99jun/19990620.html">
User Friendly</a> comic.

<EM>The long-awaited and much-needed "third choice" in Desktop
Environments for X ...</EM>
<p>One of the biggest debates in the Free/Open Source Software community
over the past year has been over KDE and GNOME. Perhaps the major
bone of contention between the two camps was the issue of licensing,
specifically the proprietary nature of the Qt library used by KDE.
<p>During these debates and outright flame wars, an alternative was
lurking in the background. Called XFce, it was a lighter-weight
desktop environment. One could reasonably consider it a middle-ground
solution: more configurable than running a window manager such as
FVWM, but not the behemoth of KDE or the then-nascent GNOME.
Unfortunately, XFce suffered from the same flaw -- a fatal flaw in the
eyes of many -- as KDE: XFce was based on the Xforms library, a
proprietary widget set for the X Window System.
<p>Well, there is now some very good news for Free Software enthusiasts!
Olivier Fourdan, author of XFce, has taken the dramatic step of
rewriting the whole project, using the GIMP toolkit. Finally, we have
what many consider the "holy grail" of desktop environments for X:
a lightweight, highly configurable, reliable, attractive and
<b>100% free</b> alternative to KDE and GNOME.
<p>Recently, Olivier was kind enough to agree to an e-mail interview
and discuss these important developments.
<h3>Q: When and why did you first decide to write XFce?</h3>
<p>A: In late 1996, I started to work as a help desk analyst. As part of
this job, I was working with HP X terms running CDE. I really loved that
environment, and tried to find something similar on Linux.
Unfortunately, the only thing I found was the commercial port of the
real CDE to Linux, and it was really much too expensive for me.
<p>Then in early 1997, I started to play with XForms and fdesign, the
GUI designer. One real cool thing about fdesign is its ability to
generate compilable C code from scratch. The XFce project had started,
but as usual, I really didn't think it could go that far! I just started
coding a very basic toolbar with Xforms, and when I released the first
version on SunSITE (now called Metalab), people started asking for more
and more features.
<p>Initially, XFce was just the toolbar, without the window manager and
all the goodies. In 1998, I released XFce 2.x with xfwm, the window
manager. The rest of the goodies came from release to release ...
<h3>Q: What compelled you to rewrite XFce using the GIMP toolkit? Was
it for technical reasons, licensing reasons, or some mix of both?</h3>
<p>A: I was thinking of porting XFce to GTK+ (the GIMP toolkit) for a long
time. When the GNOME project started, somebody from the team sent me a
mail from Mexico telling me they were starting a new desktop project
with the GIMP toolkit and were looking for such a toolbar.
Unfortunately, I did not know anything about GTK+ at that time and my
skills in X programming were not as good as they are today.
<p>Last year, when I released XFce 2.x, I talked with the people from
Red Hat to see if they could use XFce in their distribution, but they
did not want Xforms-based applications because of the license the
library uses (it's free for private use and free applications, but the
source code is not available).
<p>As time passed, more and more projects were being based on the GIMP
toolkit. I had to make something really new with XFce, include drag and
drop, native language support, improve configurability, etc. So, at the
end of March 1999, I decided to start XFce 3.0 and rewrite it entirely
from scratch with GTK+.
<p>Now I'm really glad I did that, XFce 3.0 is still fast and stable,
and it features all I wanted for XFce, under the GNU General Public
License, based exclusively on GNU tools (NLS, autoconf, automake, etc.)
<h3>Q: Do you know which Linux distributions ship with XFce? And do
you know of any that will now ship with XFce3?</h3>
<p>A: I think Red Hat and SuSE both ship XFce 2.x on their additional
software packages, and Kevin Donnely has made a package for Debian. But
still, as XFce 2.x was based on Xforms, none of these distributions
include XFce in their base system. I know FreeBSD also provides XFce 2.x
as an additional package.
<p>XFce 3.0 is now all GPL, but I guess it is still much too recent
to be included in any distribution -- although I really hope some
distribution will include XFce 3.0 in their base packages, among other
choices for the user.
<h3>Q: What do you think of GNOME and KDE, in general? Can you briefly
summarize the relative merits of each versus XFce3?</h3>
<p>A: KDE is the first attempt to provide Linux with a fully integrated
desktop environment. I've been impressed by KDE 1.1! Unfortunately, KDE
is too close to Microsoft Windows; I really don't like the "Start
menu" style. Sometimes you have to go through several submenus to
launch what you want (but this is a matter of taste). Moreover, KDE uses a
lot of system resources. For example, I was not able to use KDE on an X
terminal through a 10MB local network, whereas XFce works like a charm in
such a configuration.
<p>I don't know much about GNOME, as I could not make it work on my
computer. But what I saw from it was very close to KDE, so the same
remarks apply to GNOME. It seems to be so close to KDE that I don't
understand what the need was for two similar environments on Linux.
<p>I believe the desktop environment should be made to increase
user productivity. Therefore, the goal is to keep most system resources for
the applications, and not to consume all memory and CPU usage with the
desktop environment. For example, does KDE or GNOME fit on a 1.44 MB
floppy?
<p>GNOME and KDE both provide a lot more integrated tools than XFce
(although most of the time, separate tools are more powerful than the
integrated ones; for example, I believe NEdit is better than any
other Kedit or whatever). The exception is KFM, the KDE File Manager,
which is far ahead the best program of all in KDE, in my opinion.
<p>Some people say XFce is for the little systems, while GNOME and KDE
are for bigger ones. I don't agree; the more memory and CPU you save for
your applications, the better it is. And if you still want to use KDE
and GNOME tools, because they are convenient for you, you can use them
under XFce, as its window manager is supposed to be compatible with
these applications, too.
<h3>Q: XFce3 -- could it be your new desktop environment?</h3>
<p>A: If you are looking for an alternative to KDE or GNOME, I strongly
recommend investigating XFce3. It's small and efficient. It's
functional and attractive. And now, it's 100% GPL software. Olivier
has just completed an upgrade to the XFce main page. It includes links
for downloading mirrors and the HTML on-line manual for XFce3.
<p>Hopefully, all of the distributions will start shipping XFce as an
optional desktop environment. It would be even better if at least one
of the distributions would ship XFce3 as the default option. The Free
Software community is famous for giving users a choice. XFce3 is now a
fantastic choice for people who want a free option other than KDE or
GNOME. By shipping XFce3 as a default desktop, perhaps one of the
smaller, more up-and-coming distributions could make itself stand out
from the KDE/GNOME crowd. XFce is a natural fit for any distribution
trying to make itself known as a faster, lighter-weight Linux option.
<p>In any case, XFce3 is worth a look.

<h1> What is Kickstart?</h1>
<p>
One note,
I think it would be a good
if someone made a follow-up article for other Linux distributions. I would
be more than happy to help.
<p>
KickStart for RedHat makes it so you can do a quick installation of RedHat 6.0
without having to go through all the installation menus. It automates it
for you from start to finish (assuming nothing goofs up in between). This
is handy for multiple installations.
All
you have to do is create a "ks.cfg" file on the RedHat 6.0 boot disk. Then
boot off of the disk, type in the command "linux ks=floppy" on the first screen,
and if you are lucky, when it starts the installation process, it should
be able to grab that file and do the whole installation for you.
<p>
Here are the key points you need to be aware of,
<ol>
<li> If you don't have a bootdisk for RedHat 6.0, you need to make one.
Either use "rawrite" that comes on a RedHat 6.0 cd while in DOS, or mount the
cd in Linux and assuming you mounted the cd at /mnt/cdrom and you have
a floppy disk in (that doesn't have anything important on it),
<br> cd /mnt/cdrom/images
<br> dd if=boot.img of=/dev/fd0
<br> ## OR if you are installing off the net
<br> dd if=bootnet.img of=/dev/fd0
<li> The RedHat 6.0 boot disk is formatted as an msdos disk, thus you can
copy the "ks.cfg" file to it in Windoze or in Linux. If you need to
mount the floppy disk in Linux, try,
<br> mkdir -p /mnt/floppy
<br> mount -t msdos /dev/fd0 /mnt/floppy
<li> Kickstart can be installed using a cdrom, over the net through
ftp or nfs, and for multiple computers you can use DHCP. It has other features
as well. For this example, we will use a static ip addresses.
<li> It is assumed we are using standard IDE hard drives and cdroms. If you
have SCSI devices, or other weird devices, you will have to modify the
kickstart file so that it will work.
<li> Something weird happened on one of my installs. After installing
RedHat 60, I tried to do an upgrade and somehow it found over 100 megs
of programs to install as an upgrade even though I didn't do anything to
the system. Weird. I did it again, and it installed 115 packages which
had a total of 112 megs. I don't think it had to install those rpms again,
but that it was an automatic thing with the upgrade option , whether or
not you have those
rpms installed.
</ol>
<hr>
<a name="Gripes"></a>
<h1> Gripes and Complaints</h1>
Well, I have some gripes and complaints. Overall, the kickstart disk is pretty
cool and has improved since 5.2, but still, it seems a little braindead
or it doesn't give you the absolute power you need sometimes.
I want the ability to shoot myself in the foot if I want to. It might sound
weird, but here are my points:
<ol>
<li> I couldn't find a "select all rpms" option. This makes it annoying
since I have to list all the rpms. Perhaps I was blind, but I
didn't find that option.
<li> I can't tell it to force a graphics card and monitor settings with
a certain resolution. This is annoying. Xconfigurator doesn't work
for me half the time, and I need to configure Xwindows after an
installation. An easy way to do this, in a manual installation,
is to set the computer to
VGA 16 and to install the drivers for the true card later. If you
set it to VGA 16 and it thinks it is something else, kickstart will
error and stop the installation process and ask you for more info.
<li> I wish I could force the name of the computer so that it doesn't
stop and ask you what the name of the computer should be if it doesn't
find it in the DNS server. I would like the ability to shoot myself
in the foot and put in incorrect settings just because I want to.
<li> It is pretty stupid about making Linux partitions. It only wants
to see one primary partition and to put everything else into
logical partitions. This is silly especially in multi-boot systems.
It just grabs the rest of the hard drive space after the primary
partition and puts it all into one extended partition. I would like
the ability to specify primary or logical partitions.
It would be
nice if someone were to help make it so you can create a script
which would automate the commands for fdisk. Perhaps there is
and I just don't know about it.
<li> Is there a way to tell it to use a partition that is already defined?
It seems as though it only can use the partitions that it creates. It
would be nice if I could define the partitions ahead of time,
and in the kickstart disk tell it which partitions go to which
directories.
</ol>
Don't get me wrong, kickstart is a cool way of doing things, I just would
like to see it brought to a different level where it is "very" cool. Cool =
give me all the power to shoot myself in the foot just so I can see what
happens. A little bit of pain never hurts anyone. Also, I am not a real
expert at Kickstart, so perhaps I just didn't catch some of the options I
am griping about. I have only been using it for about 2 months at the time
of this document.

<a name="Example"></a>
<h1> Cdrom upgrade example</h1>
<p>
Copy what is between the lines to a file called "ks.cfg" to your boot disk.
Then, when you get to the
first screen of the Linux installation, type "linux ks=floppy". Also,
before you do this, make sure the BIOS in your computer is set to boot
off of the floppy drive.
<br>
<pre>
# Copy this file as "ks.cfg" to the boot disk that comes with
# RedHat 6.0. Or make your own boot disk. Anyways, the
# bootdisk is formatted msdos, so you can use a Windows
# computer to copy this file to it. Also, when the prompt
# comes up after you boot off of the floppy disk, type
# linux ks=floppy
# and press enter.
# This is just the configuration you need to do an upgrade using a cdrom.
#

</pre>
<br>
<hr>
<a name="ftp"></a>
<h1> An installation over ftp</h1>
<p>
Well, this configuration uses ftp, and if you wanted to use nfs,
you could comment
the ftp option and uncomment the nfs option. All you need is a floppy
drive and a network card. Makes things a little easier if you can cut
out a cdrom drive in each of your computers. Also, use a 100 mbit network.
My installations using ftp were actually faster than installing off of
the cdrom when I had a 100 mbit network. A 40 speed cdrom still isn't as
good as a fast network with a few computers. A 100 mbit hub is really
cheap these days.

### Tell it to use an Intel 10/100 EtherExpress ethernet Card

### Tell it to use a us keyboard

### Tell it to blow away the master boot record on the hard drive
zerombr yes
### Tell it to do a dumb move and blow away all partitions

### Make a swap partition, and unfortunately, this will go on a
### logical partition.

### It will make a primary partition for root, 2 gigs
### I couldn't find a command to check for bad sectors. Is there one?
### I don't think "grow" will work here, unfortunately
part / --size 2000
### Make a directory /OtherDir which is at least 1 gig and grows
### to fill out the rest of the hard drive
### Since "Kickstart" is literally an unintelligent program,
### it will put this partition on a logical partition
### even though there are plenty of primary partitions to use.
part /Backups --size 1000 --grow
### Tell it to use a MicroSoft compatible mouse
mouse --kickstart microsoft --device ttyS1
### Let it know we are doing an install and not an upgrade
install
### Tell the timezone we are in
timezone --utc US/Eastern
### Tell it to use standard VGA 16, but sometimes it croaks
### at this point and asks you anyways to select a card
### I really wish you could force to install for a particular
### card so that you can "configure" Xwindows after installation
### Xconfigurator gets it wrong %50 of the time for my cards
xconfig --server XF86_VGA16
#### Give it a dumb root password
rootpw MyPassword
#### Tell it to use shadow passwording
auth --useshadow
### Tell it to install Lilo at the master boot record
lilo --location mbr
### Now let us install packages, is there a simple command for all?
%packages
### Select the packages to install, I think this is all of them
### Unlike the installation program which only installs one X Server,
### my options installs all of them in case you switch video cards,
### which I do a lot.

<h1> Conclusion -- it is good</h1>
I think the RedHat Kickstart stuff is good. I never did find out if the
other distributions have it, didn't have enough time. Oh well. It still needs
a lot of work to make it a really cool way of doing installations. The
problem is, instead of just bitching about it, if it needs work, and you like
it, contribute to the cause and help develop kickstart for RedHat or for
any other Linux distribution. I wrote this article, now, you
help out and contact the RedHat folks or other people to make the process
even more cool!
<p>
Overall, I give Kickstart method a "B" for 6.0, and a "C" for the 5.2
version. It is cool compared to the corrupted commercial alternative which
forces you to reboot 10 times before it is done installing. The potential
for Linux is amazing compared to commercial closed sourced alternatives.
When software is written not because of profit but because it is cool
and/or because people want it done right,
the long term potential far outweighs the short-term
profit-minded mentality of people who cannot write good software
or who just
want things done "just to get it to work". Kickstart has the potential to
reduce the overall cost of consulting and the time it takes to install Linux
systems on a mass scale (which benefits the novice and expert
computer consultant). It is funny to watch commercial companies who are
trying to emulate what Linux and other UNIX systems can do. I see commercial
products out there which attempt to do mass installations for closed
sourced corrupted operating systems and I laugh at all the hard work they
have to do. I want to stress something, this method I have shown today
is not the easiest method to install Linux. I will explain this in
another article someday. It will make any commercial or closed sourced
operating system look like garbage compared to Linux.

<h1> My perl script</h1>
I used this perl script to extract a list of rpms from the /RedHat/RPMS
directory on the cdrom. I only had about 6 corrections to make and figured
it would take me longer to fix the perl script that it would be to fix
the list. There has to be a simpler way of getting the list with exact
results, but often
it is just a decision between what you know works, and taking the time
to figure out a better way. It only took me 5 minutes to write this
script. Most of the time wasted was booting off of the kickstart disk
to see how many errors I got.
<pre>
#!/usr/bin/perl
my @RPMS = &lt;/home/ftp/RedHat60/RedHat/RPMS/*.rpm&gt;;
my $Dest = "/tmp/List_2.txt";
open(FILE,">$Dest");
foreach $Rpm (@RPMS)
{
## Would be easier if I had used ? instead of /
$Rpm =~ s/\/home\/ftp\/RedHat60\/RedHat\/RPMS\///;
if ($Rpm =~ /\-[0-9]+\-[0-9]+\./)
{($Rpm,$Junk) = split(/\-[0-9]+\-[0-9]\./, $Rpm,2);}
elsif ($Rpm =~ /\-[0-9]+\./)
{($Rpm,$Junk) = split(/\-[0-9]+\./, $Rpm,2);}
else {($Rpm,$Junk) = split(/\-[0-9]/, $Rpm,2);}
print FILE "$Rpm\n";
}

<br>CHANGES:
<ol>
<li> Changed XServers File located at /etc/X11/xdm/Xservers by adding
these lines to get 4 xdm sessions running so that 4 different people
can log in. It seems like all the neat stuff only happened on the last
session. It is probably easy to fix this. Perhaps I will mention it in
the next article.

<li>man xdm
<li><a href="http://www.tcu-inc.com/mark/projects/xdm/">
My old xdm cheat sheet</a> back in 12/1996 when I was just a hacker (in the
good sense). I guess this was around right when the Gazette got started?
How time flies. I should have posted this there at that time.

<a name="What"></a>
<h1> What is XDM?</h1>
To put it simply, xdm is just a graphical login screen so that you
can impress your boss or friends that you don't have some boring
console to look at when your computer starts up.
It just makes Linux a little bit more cool than
someone might have previously thought.
<p>
In theory, most of configurations here should work for any Linux
distribution. This is configured for RedHat 6.0 though. RedHat 6.0 uses
gdm instead of xdm when it starts its graphical login screen. However,
I haven't got gdm to work in the exact way I want it, even though it
seems much better than xdm. Once I figure out a few things, I will
write a brief article on gdm also.
<p>
Here are some things to note ,
<ol>
<li> If you want xdm (or gdm) to start when you computer starts, you need
to make sure this line<br>
id:3:initdefault:
<br> Looks like this <br>
id:5:initdefault:
<br> in the file "/etc/inittab". Please, whatever you do, get
Xwindows working before you set xdm to start at bootup. If Xwindows
doesn't work, xdm won't work, and that can cause problems.
<li> RedHat 6.0 switched to gdm instead of using xdm
which is apparent at the bottom of the
/etc/inittab with the line <br>
x:5:respawn:/etc/X11/prefdm -nodaemon
<br> thus, change that line to this,
<br> x:5:respawn:/usr/bin/X11/xdm -nodaemon
<li> All the files I am changing are in "/etc/X11/xdm".
</ol>
<hr>
<a name="Configs"></a>
<h1> My config files</h1>
I am only interested in a few files, namely
<br> /etc/X11/xdm/Xsetup_0
<br> /etc/X11/xdm/Xresources
<br> /etc/X11/xdm/GiveConsole
<br> /etc/rc.d/rc.change_graphic
<br> /etc/rc.d/rc.local
<br> /etc/inittab &lt;-- this was explained above
<br> and the gif files in /etc/X11/xdm/graphics/
<p>
Here is the goal, I want to change xdm to make it so it has xeyes,
santa, a clock, a graphics image, and my choice of background color
on the desktop before someone logs in. After they log in, I want santa
to die. Cruel huh?
<p>
Okay, let us do this in order:
<ol>
<li> Copy my <a href="#perl"> graphics perl script</a> to
"/etc/rc.d/rc.change_graphic". This changes the image which appears on
the screen. Images are stored in /etc/X11/xdm/graphics as gif files.
<li> Copy my <a href="#perlkill"> kill santa perl script</a> to
"/etc/X11/xdm/KillXsnow". This kills santa. Santa slows down the desktop.
<li> Copy my <a href="#Xsetup"> Xsetup script</a> to
"/etc/X11/xdm/Xsetup_0". Programs to run with the graphical
login screen.
<li> Copy my <a href="#Xresources"> Xresources script</a> to
"/etc/X11/xdm/Xresources". How the setup of xdm should look like.
<li> Copy my <a href="#GiveConsole"> GiveConsole script</a> to
"/etc/X11/xdm/GiveConsole". Stuff to get executed before Xwindows
is handed over to the user. Also, changes the background image for
xdm.
<li> Add <a href="#local"> this command </a> to "/etc/rc.d/rc.local".
Make sure we get a graphics image to look at when we boot up.
<li> Copy my <a href="http://www.tcu-inc.com/mark/articles/xdm/xdm.tgz">
gif files</a> to
"/etc/X11/xdm/graphics/" and issue this command on the file
<br>
tar -C / -zxvf xdm.tgz
<br> These are just my silly images I use.

<a name="Conclusion"></a>
<h1> Conclusion</h1>
XDM is pretty cool. This is the old way of doing things. I recommend
going to gdm or something else. For XDM, I give it a B-. It just lacks
some of the stuff I always wanted to see that gdm has.
<p>
I will explain GDM next time. Gdm has
the nice capability of letting you choose which desktop environment
you want. In RedHat 6.0, you can choose KDE, GNOME, or other desktop
environments when you login, which is pretty cool. Overall, I give gdm
a B+, and if it becomes better documented, an A. Again, I hope to make
an article about gdm for the August issue.

<H1><font color="maroon">Syslog-ng</font></H1>
<H4>By <a href="mailto:bazsi@balabit.hu">Balazs Scheidler</a></H4>
</center>
<P> <HR> <P>
<H2>1. Introduction</H2>
<P> One of the most neglected area of Unix is handling system events. Daily
checks for system messages is crucial for the security and health conditions
of a computer system.
<P> System logs contain much "noise" - messages which have no importance - and
on the contrary important events, which should not be lost in the load of
messages. With current tools it's difficult to select which messages we are
interested in.
<P> A message is sent to different destinations based on the assigned
facility/priority pair. There are 12+8 (12 real and 8 local) predefined
facilities (mail, news, auth etc.), and 8 different priorities (ranging from
alert to debug).
<P> One problem is that there are facilities which are too general (daemon),
and these facilities are used by many programs, even if they do not relate
each other. It is difficult to find the interesting bits from the enourmous
amount of messages.
<P> A second problem is that there are very few programs which allow setting
their "facility code" to log under. It's at best a compile time parameter.
<P> So using facilities as a means of filtering is not the best way. For it
to be a good solution would require runtime option for all applications, which
specifies the log facility to log under, and the ability to create new
facilities in syslogd. Neither of these are available, and the first is neither
feasible.
<P> One of the design principles of syslog-ng was to make message filtering
much more fine-grained. syslog-ng is able to filter messages based on the
contents of messages in addition to the priority/facility pair. This way only
the messages we are really interested in get to a specific destination. Another
design principle was to make logforwarding between firewalled segments easier:
long hostname format, which makes it easy to find the originating and chain of
forwarding hosts even if a log message traverses several computers. And last
principle was a clean and powerful configuration file format.
<P> This article tries to give you an overview on syslog-ng's internals, for
more detailed information see
<A HREF=http://www.balabit.hu/products/syslog-ng>
http://www.balabit.hu/products/syslog-ng</A>
and select the documentation link.
<H2>2. Message paths</H2>
<P> In syslog-ng a message path (or message route) consist of one or more
sources, one or more filtering rules and one or more destinations (sinks).
A message is entered to syslog-ng in one of its sources, if that message
matches the filtering rules it goes out using one of the destinations.
<H2>2.1. Sources</H2>
<P> A source is a collection of source drivers, which collect messages using a
given method. For instance there's a source driver for AF_UNIX, SOCK_STREAM
style sockets, which is used by the Linux syslog() call.
<P> Different platforms use different means of sending log messages to the
logging daemon, and to be useful on all operating systems, syslog-ng has
support for the most common methods. Tested support exists for Linux, BSDi,
experimental support exists for Solaris (as of version 1.1.22)
<H2>2.2. Destinations</H2>
<P> A destination is a message sink, where log is sent if filtering rules match.
Similarly to sources, destinations may include several drivers which define
how messages are dispatched.
<P> For instance there's a file driver, which writes messages to the given file,
but support exists to send messages to unix, udp and tcp sockets as well.
<H2>2.3. Filters</H2>
<P> Filters perform log routing inside syslog-ng. You can write a boolean
expression using internal functions, which has to evaluate to true for the
message to pass.
<P> An expression may contain the operators "and", "or" and "not", and the
following functions:
<UL>
<LI> facility()
<LI> level()
<LI> program()
<LI> host()
<LI> match()
</UL>
<P> Each of the above functions check the corresponding field of a log message
for matching (e.g. program() checks whether the given program sent the message,
or not). You can use extended regular expressions for matching.
<H2>2.4. Log statements</H2>
<P> Now you have sources, destinations and filters. To connect these together
you need the log statement:
<PRE>
log { source s1; source s2; ...
filter f1; filter f2; ...
destination d1; destination d2; ... };
</PRE>
<P> Messages coming from any of the listed sources, and matching against all
the listed filters (which effectively ANDs them) are sent to all of the listed
destinations.
<H2>3. Example configuration</H2>
<P> This configuration file shows the possibilities and features of syslog-ng.
It receives messages from the network, and also handles local messages. Three
distinct output files are used: one for the messages from sendmail, a second
for messages coming from host1, and a third for messages coming from host2.
<PRE>
options { long_hostnames(on); sync(0); };
source src { udp 0.0.0.0,514; unix-stream /dev/log; internal; };
filter f_sendmail { program("sendmail"); };
filter f_host1 { host("host1"); };
filter f_host2 { host("host2"); };
destination sendmail { file /var/log/sendmail; };
destination host1 { file /var/log/host1; };
destination host2 { file /var/log/host2; };
log { source src; filter f_sendmail; destination sendmail; };
log { source src; filter f_host1; destination host1; };
log { source src; filter f_host2; destination host2; };
</PRE>

<H1><font color="maroon">Artificial Intelligence on Linux</font></H1>
<H4>By <a href="mailto:afsilva@liberty.edu">Anderson Silva</a></H4>
</center>
<P> <HR> <P>
Artificial Intelligence is a very controversial subject, but the
way I will approach it in this article is simple and fast. The
way I have been approaching AI is not through the philosophical
or biological aspect, but just as a computational subject.
When humans want to fly, they don't need to study the birds to
learn how to do it, they just get into an airplane. This is my
way of approaching AI. We want to solve puzzles and games through
a computer without really comparing the way a human accomplishes
tasks differently from a computer.
<P> For the first time in the history of my school, there was going
to be offered an Artificial Intelligence (AI) class. I was very
excited about this class because you hear a lot about AI, but you
don't really see a lot of material for it on magazines and online
articles.
<P> Probably the greatest example of an AI application is Turing's
Test. The test consists in a person being a room with a computer
terminal, and this person would start to chat with the computer.
At the end the person would have to figure out if he talked to a
real person on the other end of the terminal or with a computer
program. And if the user confuses the person with the computer
then we would have reached AI.
<P> At, LU we chose Prolog to be the implementation tool for AI. Our
labs at school are Windows NT based and we have only one linux
machine which is designated to students. But I have been a linux
user for almost 2 years, and I wanted to implement all my Prolog
assignments in Linux.
<P> I did some research on the web and I found a great Prolog
compiler for linux. Prolog is like linux in a certain way, there
are several flavors that you can pick from. The one I chose was
SWI Prolog (http://www.hio.hen.nl/faq/SWI-Prolog.html).
Prolog is a very flexible language. Unlike other languages like
C, C++ or Java, Prolog is based on formal mathematical logic, in
this case: Predicate Calculus. A Prolog program is normally made
of facts with a set of rules. To reach the final solution
it has to satisfy this set of rules. Interpreting these rules
allows the computer to deduce the solution by itself. In Prolog
the facts are normally stored on a separate file called
the knowledge base, and rules on another file that is the actual
program.
<P> Allow me to show a very basic search algorithm known as the
<A HREF="gx/silva.ai.jpg">Depth First Search</A> (click for image).

<P> The Program below is the representation of the graph above in
Prolog.

<H4>By <a href="mailto:stu7440@westga.edu">Terry 'Mongoose' Hendrix II</a>
and <a href="mailto:afsilva@liberty.edu">Anderson Silva</a></H4>

<P> <HR> <P>
<p> Last Month, my brother and I decided that we
were going to setup a small network at my house, so that we could connect
more than one computer to the internet with only one modem and one phone
line.&nbsp; My machine is the one with the modem and it is also running
Linux (server)&nbsp;. My brother's machine is running Windows 95 (Client).
I did some research and found some documentation about private networking
on the web. I decided to try the technique of IP Masquerading with our
little network at home.
<br> IP Masquerading is the technique to assign
your computers internal IP addresses (in my case 10.0.0.1 for the server
and 10.0.0.2 for the client) and share your machines internet connection
with the other clients without having to assign them a external IP address.
I read a lot of the documentation and I did actually understand the whole
process, but I could not get it running right on my computer. So, I&nbsp;entered
the #Linux IRC channel on Undernet.org and found a guy nicknamed Mongoose
to help me.
<br> He gave me a link to a quick tutorial he had
written to get IP MASQ running with ipchains* in no time.
<p>* Ipchains is a program that is bundled with RedHat 6.0 and is used
to set up firewalls and ip masquerading.
<p> After reading Mongoose's tutorial I had my
private network running in less than 10 minutes. That is why I got in touch
with him and he agreed to let me publish his tutorial to the Linux Gazette.
<p>Bellow is the Tutorial:
<br>&nbsp;
<p>----------------------------------------
<br>NOTES
<br>----------------------------------------
<br>The following example has:
<p>&nbsp; 0.0.0.0 the IP of the gateway to the internet.
<br>&nbsp;10.0.0.1 the IP of the ip masq gateway's eth0.
<br>&nbsp;10.0.0.2 the IP of the ip masq client0's eth0.
<br>&nbsp;10.0.0.3 the IP of the ip masq client1's eth0.
<br>&nbsp;
<p>NETWORK IP MASQ GATEWAY SETUP
<br>----------------------------------------
<br>1. Load ethernet card modules ( if needed ).
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /sbin/modprobe ne2k-pci&nbsp;&nbsp;
(each card has a specific name)
<p>2. Bring up the device.
<br>&nbsp;&nbsp; ( add to /etc/rc.d/rc.local if you don't have standard
interface scripts)
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /sbin/ifconfig eth0 10.0.0.1
netmask 255.255.255.0 up
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /sbin/route add -net 10.0.0.0
netmask 255.255.255.0 eth0
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /sbin/route add default
gw 0.0.0.0 eth0
<p>3. Allow your IP MASQ clients to use your inet.
<br>&nbsp;&nbsp; A. Add this to /etc/hosts.allow at the end:
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ALL:10.0.0.2
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ALL:10.0.0.3
<p>&nbsp;&nbsp; B. Add the ips to any other configs it requires.
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; i. I suggest you use the squid ftp/http
proxy for speed.
<br>&nbsp;
<p>NETWORK CLIENT SETUP ( 10.0.0.2 client0 )
<br>----------------------------------------
<br>1. Load ethernet card modules ( if needed ).
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /sbin/modprobe ne2k-pci
<p>2. Bring up the device. ( add this to /etc/rc.d/rc.local if you don't
have standard interface scripts)
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /sbin/ifconfig eth0 10.0.0.2
netmask 255.255.255.0 up
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /sbin/route add -net 10.0.0.0
netmask 255.255.255.0 eth0
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /sbin/route add default
gw 10.0.0.1 eth0
<br>&nbsp;
<p>TESTING NETWORK
<br>----------------------------------------
<br>1. Ping 10.0.0.1 from the the clients and vice versa.
<p>2. Use /sbin/ifconfig to see packet traffic from each host.
<p>3. You should be able to use telnet/ftp between machines now.
<br>&nbsp;&nbsp; A. If you can't telnet from clients to gateway, then check
hosts.allow.
<br>&nbsp;
<p>IP MASQ GATEWAY IP MASQ SETUP
<br>----------------------------------------
<br>1. IP forwarding setup.
<br>&nbsp;&nbsp; A. Enable ip forwarding for the IP MASQ gateway.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; echo "1" > proc/sys/net/ipv4/ip_forward
<p>&nbsp;&nbsp; B. Make ip forwarding enabled every boot:
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; i. For RedHat modify /etc/sysconfig/network
as follows:
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; FORWARD_IPV4=true
<p>&nbsp;&nbsp;&nbsp;&nbsp; ii. For other distros add this to /etc/rc.d/rc.local
at the end:
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; echo "1" > proc/sys/net/ipv4/ip_forward
<p>&nbsp;&nbsp; C. To make sure no one smurfs your network add this to
rc.local:
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; echo "1" > /proc/sys/net/ipv4/tcp_syncookies
<br>&nbsp;
<p>2. Now setup routing.&nbsp; You can add these to rc.local to load every
time.
<br>&nbsp;&nbsp; A. Deny all ip forwarding by default.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /sbin/ipchains -P forward
DENY
<p>&nbsp;&nbsp; B. Allow ip forwarding for your IP MASQ machines 10.0.0.2
and 10.0.0.3.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /sbin/ipchains -A forward
-s 10.0.0.2/24 -j MASQ
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /sbin/ipchains -A
forward -s 10.0.0.3/24 -j MASQ
<p>&nbsp;&nbsp; C. Add any masq modules you'll need.
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /sbin/modprobe ip_masq_ftp
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /sbin/modprobe ip_masq_quake
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /sbin/modprobe ip_masq_irc
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /sbin/modprobe ip_masq_user
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /sbin/modprobe ip_masq_raudio
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ...
<p>
<hr>
<p> If you follow this tutorial your network should
work just fine. One other problem that I encountered after setting up my
IP MASQ was that my client could only access servers on the net with their
IP addresses. So, I set up DNS on my linux box, so my clents could do a
domain lookup. All you need to do is to set <b>/etc/resolv.conf</b> with
your nameservers, and make sure that you have the <b>named</b> daemon is
activated. And that should solve the problem.
<P> And if you have done all of these steps
you should be all set to run your private network. If you want to learn
more about IP MASQ and Firewalling please refer to the HOWTOs Documentation

<P> Today I am 21 years old, and I still like playing around
with LOGO. And I will use it to teach my son a little bit about
programming and discrete math concepts. Now, my challenge was to
find a version of LOGO for Linux. I have been using Linux for
about 2 years now, and just a couple of weeks ago I started
searching the web for a free version of LOGO for Linux. It took
me about 30 minutes, but I was able to find the Berkeley LOGO
version, which is really good. It runs in many Unix flavors and
works with MS Operating Systems as well.</P>
<P> I was able to compile it with Red Hat 5.2 pretty fast and
it worked great, but I did encounter several errors with Red Hat
6.0, and i am still trying to figure out some incompatibilities.
The Berkeley distribution of LOGO can be downloaded it at:
<A HREF="ftp://anarres.cs.berkeley.edu/pub/ucblogo/">ftp://anarres.cs.berkeley.edu/pub/ucblogo/</A></P>
<P> The distribution comes with a pretty good user manual,
and it has at least 3 different versions available for download.
I do encourage any programmers that have children to download
LOGO and start having fun with your children, they will have a
blast, and you can even take the opportunity to teach them some
basic Linux tasks.

<H1><font color="maroon">Setting Up Mail for a Home Network Using Exim</font></H1>
<H4>By <a href="mailto:JW.Stumpel@inter.NL.net">Jan Stumpel</a></H4>
[Revised at author's request. Originally published in issue #42.]
</center>
<P> <HR> <P>
<h4><a NAME="exim1"></a>1 Introduction</h4>
Setting up a home network with Linux and Win95, using Samba, IP
Masquerading, and diald has been described many times, also in the Linux
Gazette, but so far I have not found a recipe for setting up <i>mail</i> on
a small network with only one dial-up e-mail account. In this article I want
to explain how I did it. With this system:
<p><ul><li> users on the network can send local mail to each other, and
reply to it, also locally.</li>
<li> outgoing mail has a proper From: address, so the outside world can
reply to it.</li>
<li> the e-mail account is shared by the users, but each only receives
his/her personal mail.</li>
<li> users on the network receive a notification (a pop-up window) when
personal mail for them arrives.</li></ul>
<p>This is realized on my system (running Debian Linux 2.1) using the
following programs:
<p><ul><li> exim as the mail transfer agent (it is
<i>much</i> easier to configure than sendmail).</li>
<li> fetchmail for collecting the mail from the ISP.</li>
<li> pine as the mail client on the Linux side (but other clients can be
used as well, including <tt>mail</tt>).</li>
<li> Microsoft Internet Mail on the Windows side (but other clients can be
used as well).</li>
<li> qpopper as the POP3 server, for moving mail from the Linux system to
the Win95 machine.</li>
<li> smbclient and Winpopup for mail notification.</li></ul>
<p>I have this set up for two machines (1 Linux + 1 Win95) but it will
probably also work for a somewhat larger network, and may be sufficient for
a small office. Note: this article is Debian-oriented. If you use another
distribution, change where appropriate!
<h4> <a NAME="exim2"></a>2 The network and the names</h4>
For this article I assume the following <i>names</i> (change these to
correspond with your own situation):
<p><ul><li> the owner / system administrator is called Joe Bloggs.</li>
<li> the Linux machine is called <b>heaven</b>.</li>
<li> the Win95 machine is called <b>earth</b>. It is mostly used by Emily
Bloggs.</li>
<li> Joe's user name on heaven is <tt>joe</tt>.</li>
<li> Emily's user name on heaven is <tt>emi</tt>.</li>
<li> Emily's user name on earth is also <tt>emi</tt>; her Linux password on
heaven and her 'password for Microsoft networking' on earth are the
same.</li>
<li> Joe has a dialup account (dynamic IP address) with an ISP called
<tt>isp.com</tt>. Mail from the ISP can be collected using POP3.</li>
<li> Joe's account name at the ISP is <tt>jbloggs</tt>.</li>
<li> Joe's e-mail address (also used by Emily) is
<tt>joe.bloggs@isp.com</tt>.</li>
<li> Joe's password for collecting POP3 mail is <tt>zaphod</tt>.</li>
<li> The ISP's mail server (for sending mail) is <tt>smtp.isp.com</tt>.</li>
<li> The ISP's POP3 server (for collecting mail) is <tt>pop3.isp.com</tt>.
</li>
<li> heaven and earth belong to a domain called <tt>home</tt>. This domain
name is meant for use only inside the home network; Joe has not registered
his domain name and it cannot be recognized by the outside world.</li> </ul>
I also assume that the local networking works, and that there is on-demand
dialup access using diald. There is no name server on heaven.
/etc/resolv.conf contains the addresses of two name servers supplied by the
ISP. These same addresses are entered into the TCP/IP configuration on
earth.
<p><tt>/etc/hostname</tt> on heaven is
<p><tt>heaven</tt>
<p><tt>/etc/hosts</tt> on heaven is
<p><tt>127.0.0.1 localhost</tt>
<br><tt>192.168.1.1 heaven.home heaven</tt>
<br><tt>192.168.1.2 earth.home earth</tt>
<p>On earth there is a file <tt>c:\windows\hosts</tt> with the same contents
as <tt>/etc/hosts</tt>.
<h4><a NAME="exim3"></a>3 Mail addresses</h4>
Mail messages can have more than just the address in the 'To:' and 'From:'
lines, for instance :
<p><tt>To: Emily Bloggs &lt;joe.bloggs@isp.com></tt>
<p>'Emily Bloggs' in the above example is the 'real-name part'. It is set in
the e-mail program which composes the message. This 'real-name part' can be
used for delivering Emily's mail to her. Note: if the 'real-name part' has
dots in it, it must be quoted using " characters ("Joe C. Bloggs"). See also
<tt>man mailaddr</tt>.
<h4> <a NAME="exim4"></a>4 Configuring exim</h4>
On a Debian system this is done by running <tt>eximconfig. </tt>It asks a
number of questions which you can answer as follows:
<p><ul><li>your system is an Internet site using smarthost.</li>
<li>the 'visible mail domain' is <tt>home</tt></li>
<li>other names apart from <tt>home</tt> and <tt>heaven.home</tt>: answer
<tt>heaven:localhost</tt></li>
<li>you don't want to relay for any non-local domains.</li>
<li>you want to relay for the local network <tt>192.168.1.0/16</tt></li>
<li>RBL (spam filter database): whatever you like. I said <tt>n</tt></li>
<li>The smarthost, handling outgoing mail, is <tt>smtp.isp.com</tt></li>
<li>System administrator mail should go to <tt>joe</tt> (not to
<tt>root</tt>!)</li> </ul>
In MS Internet Mail (or whatever mail client you use on Win95) <tt>heaven</tt>
must be entered both as the SMTP server and as the POP3 server. Under 'pop3
account' and 'pop3 password', enter the username <tt>emi</tt> and her Linux
password. Enter the the name, Emily Bloggs, and the e-mail address, <tt>emi@home</tt>,
in the appropriate place. Note that the e-mail address must be in the <i>local
domain</i>!
<p>On the Linux side, nothing special has to be set. /etc/pine/conf and
the users' ~/.pinerc can be used 'out of the box'. The mail client (pine)
constructs local addresses using the hostname together with user information
from /etc/passwd.
<p>With the above setup, local users can happily send mail to each other
and reply to it. For instance, in pine at heaven, user <tt>joe</tt> sends
mail to user <tt>emi</tt>. Automatically, pine changes this to:
<p><tt>To: Emily Bloggs &lt;emi@heaven.home></tt>
<p>The message is delivered immediately (as you can see if you run eximon,
the exim monitoring utility). <tt>emi</tt> (should she log in to heaven)
would see the message as coming from
<p><tt>From: Joe Bloggs &lt;joe@home></tt>
<p>So <tt>home</tt> really functions like a local domain within which messages
can be exchanged. The problem is sending messages to the outside world.
A From: address like <tt>&lt;joe@home></tt> is no good because nobody on
the outside could reply to an address in the non-existent domain <tt>home</tt>.
<h4><a NAME="exim5"></a>5 Fixing the From: address</h4>
We must change the local From: address into a valid e-mail address (the
e-mail account at the ISP), but <i>only</i> in the case of outgoing messages.
With exim, we can do this by means of a 'transport filter'. The outgoing
mail passes through this filter, and the From: address is changed. Local
mail will not be affected.
<p>The following filter will do the trick, provided we are <i>sure</i> that
the address that we want to change is always between &lt; and > signs. This
is not guaranteed, but <i>very</i> common: <tt>pine</tt>, <tt>mutt</tt>, and
<tt>mail</tt>, as well as MS Internet Mail all generate such addresses.
<p><pre>
#!/usr/bin/perl
$address = 'joe.bloggs@isp.com';
while (&lt;>) {
if (/^From: /) { s/&lt;.*>/&lt;$address>/; print; last; }
print; }
while (&lt;>) { print; }
</pre>
Don't forget to change the e-mail address to yours! Call this program
<tt>outfilt</tt>, do <tt>chmod +x outfilt</tt> and put it in
<tt>/usr/local/bin</tt>. Now we must add a line to <tt>/etc/exim.conf</tt>, so the
last lines of the <tt>TRANSPORTS CONFIGURATION</tt> section read:
<p><pre>remote_smtp:
driver = smtp
headers_remove = "sender"
transport_filter = "/usr/local/bin/outfilt"
end</pre>
Actually, we added <i>two</i> lines. The <tt>headers_remove</tt> line is
also new. This prevents exim from adding a Sender: header to the message (as
it would do with this setup, if you use pine). The Sender: line can cause
trouble with some (badly configured) mail destinations.
<p>With these changes to /etc/exim.conf, whenever anyone sends an e-mail
message to the outside world it is now delivered properly by exim. Exim
(through diald) opens the outside line at once. In a home situation this is
probably what you want. In a small office, with a lot of e-mail traffic, you
may want to defer messages and send them as a bunch at certain times, to
save phone costs. This is possible, but I don't need it myself and have not
looked into it. You could look at the 'Linux Mail-Queue mini-HOWTO'.
<h4><a NAME="exim6"></a>6 Fetchmail configuration</h4>
At the command <tt>fetchmail</tt> diald opens the line and the mail from the
ISP is collected (and passed to exim for local delivery). Only users who
have a <tt>.fetchmailrc</tt>, owned by themselves, in their home directory
can run fetchmail. This file can be created using the configuration tool
fetchmailconf. You get something like:
<p><pre># Configuration created Sun Mar 28 03:15:20 1999 by fetchmailconf
set postmaster "postmaster"
poll pop3.isp.com with proto POP3
user "jbloggs" there with password "zaphod" is joe here options fetchall warnings 3600
</pre>
The <tt>.fetchmailrc</tt> files belonging to the various users could all be
copies of each other, but with the ownership set to the user concerned. It
is not so nice that every user has the password in plain view. Maybe there
is a better way, but in a home situation it does not matter.
<p>The main point is that whoever runs fetchmail, the mail must always
be delivered to the <i>same</i> user mailbox (<tt>joe</tt>'s mailbox in
this case).
<h4><a NAME="exim7"></a>7 Removing exim's delivery limit</h4>
Exim by default does not deliver more than 10 messages at a time. I am sure
there are circumstances where this makes perfect sense, but having a dialup
account is not one of them. To get rid of this restriction, you must put
into the <tt>MAIN CONFIGURATION</tt> section of <tt>/etc/exim.conf</tt>,
before the <tt>end</tt> statement, a line
<p><tt>smtp_accept_queue_per_connection = 0</tt>
<h4><a NAME="exim8"></a>8 Delivering personal mail</h4>
Through <tt>fetchmail</tt> and <tt>exim</tt>, all mail from the outside
is by default delivered to Joe's mailbox (<tt>var/spool/mail/joe</tt>)
at heaven. In Joe's home directory he puts a file called <tt>.forward</tt>,
containing the following text:
<p><tt># Exim filter</tt>
<br><tt>if $header_to: contains Emily then deliver emi endif</tt>
<p>The <tt>.forward</tt> file must have permissions <tt>-rw-r--r--</tt>. If
you're not sure, give the command <tt>chmod 644 .forward</tt>.
<p>If mail contains 'Emily' in (the 'real name part' of) the To: address
(and this will almost always be the case when her friends send her mail) it
will now go into <i>her</i> mail account on heaven, not into Joe's. She can
move the mail to her own machine using POP3 (see below).
<p>Delivery to other users than Emily can be arranged with <tt>elif ...
then</tt> clauses in the <tt>.forward</tt> file. Actually, exim's
<tt>.forward</tt> files can perform a lot of complicated functions. See the
text "Exim's user interface to mail filtering" which comes with the exim
doc's.
<h4><a NAME="exim9"></a>9 Transferring mail with qpopper</h4>
To let heaven act as POP3 server for earth, qpopper can be installed. I
installed the Debian package <tt>qpopper_2.3-4.deb</tt>. Installation is
automatic; no configuration is necessary. If Emily presses 'get/send
messages' in MS Internet Mail, the contents of her mailbox on heaven get
transferred to earth (and all mail, local or outside, which she has written
gets delivered).
<h4><a NAME="exim10"></a>10 Automatic mail notification</h4>
Emily likes to be <i>notified</i> if mail arrives for her at heaven. If Samba
is installed on heaven and Winpopup on earth, this is easy. Mail
notification on earth can be done using smbclient (a program which comes
with Samba).
<p>Joe (as root) has put a Perl program called <tt>mailwarn</tt> into
usr/local/bin:
<p><pre>#!/usr/bin/perl
open POPUP, "| smbclient -M $ARGV[0] >/dev/null 2>&1";
print POPUP "YOU'VE GOT MAIL! GO AND CHECK IT!\n";
print POPUP "It's from $ARGV[1]";
close POPUP; </pre>
<p>This file was, of course, first made executable using <tt>chmod +x
mailwarn</tt>.
<p>In Emily's home directory at heaven there is now also also a
<tt>.forward</tt> file (<tt>emi</tt> is the owner; permissions are 644):
<p><pre># Exim filter
unseen pipe "/usr/local/bin/mailwarn earth $header_from:"</pre>
<p>If mail (local or from the outside) for Emily arrives at heaven, a window
will now pop up on earth telling her this.
<h4><a NAME="exim11"></a>11 Manually collecting the outside mail</h4>
Thanks to a 'shortcut' on earth's Win95 'desktop', which does a telnet to
heaven, Emily can log into heaven and start <tt>fetchmail</tt> by hand. That
is, if she does not want to wait for the scheduled <tt>cron</tt> times when
fetchmail runs. After the mail has been transferred from the ISP, she can
press 'get/send messages' to move any mail from her heaven mailbox into the
earth one.

<h2><a name="wycd">What You Can Do</a></h2>
<p>There are a great number of ways you can help make the LPI project a
reality. Here is a quick list:</p>
<p>1. HELP ANALYZE DIFFERENCES BETWEEN LINUX DISTRIBUTIONS</p>
<p> We need some more help documenting the detailed characteristics and
differences between the distributions of Linux. Faber Fedor
&lt;revf2@interactive.net> has agreed to coordinate a project to document the
distributions. In particular we are looking for someone to complete and
maintain the SuSE document, and an additional few hands to help complete the
Slackware document are welcome too. Visit:</p>
<p> <a
href="http://userweb.interactive.net/~revf2/LPI/">http://userweb.interactive.net/~revf2/LPI/</a>
</p>
<p>to see the work that has been done to date by Faber and other volunteers.
Please send any feedback you can to Faber (preferably as an edited HTML
document, with the changes highlighted). You can also visit the archives for
the "linux-cert-program" list at:</p>
<p><a
href="http://lists.linuxcare.com/linux-cert-program/threads.html">http://lists.linuxcare.com/linux-cert-program/threads.html</a></p>
<p>to see messages relating to the project. All of this work will go into
creating the distribution-specific exams that are part of our first level of
certification.</p>
<p>2. WRITE QUESTIONS FOR OUR EXAMS</p>
<p>Very shortly, Scott Murray, our director of exam development, will be
putting out a call for "item writers" to write questions for our first level
exams. Item writers will receive some instruction in the types of questions
we are seeking and then will write items that will be submitted to an
extensive technical review and evaluation process. Writers of items that
survive the initial screening and alpha testing will receive compensation for
their work.</p>
<p>If you have ever had concerns that people who completed other certification
programs weren't really qualified, then please join with us and help make sure
our program is of the appropriate quality.</p>
<p>Please contact Scott Murray (<a
href="mailto:scott@lpi.org">scott@lpi.org</a>) now if you would be interested
in being an item writer when we begin the process.</p>
<p>3. HELP FIND FINANCIAL SPONSORS</p>
<p>Creating a high-quality certification program such as this costs a
significant amount of money. We recently unveiled our sponsorship program for
both businesses and individuals at:</p>
<p><a
href="http://www.lpi.org/sponsorship.html">http://www.lpi.org/sponsorship.html</a></p>
<p>We've already had several major sponsors come on board (Caldera Systems,
Linuxcare and SuSE are the largest) and we are actively speaking with
others. If either your company or you individually would be interested in
donating, we would certainly be interested to talk to you. If you think your
company might be interested, but are uncomfortable bringing the matter up,
please feel free to contact us and we'll be glad to make the approach.</p>
<p>Please direct all sponsorship inquiries to either myself (<a
href="mailto:dan@lpi.org">dan@lpi.org</a>) or Chuck Mead (<a
href="mailto:chuck@lpi.org">chuck@lpi.org</a>).</p>
<p>Please note that while we are incorporating as a nonprofit corporation, we
are not (yet, anyway) a "tax-exempt" entity by U.S. IRS tax guidelines.
Donations to LPI are <em>not</em> tax-deductible in the U.S. as charitable
contributions. (But there may be other ways to deduct such contributions -
contact an accountant for details - and hey, it's for a good cause
anyway!)</p>
<p>4. HELP DEVELOP A COURSEWARE APPROVAL POLICY</p>
<p>As we've had a great number of courseware vendors come to us asking about
"approving" their materials, we are considering implementing such a program.
Chuck Mead has just kicked off a discussion in our Corporate Relations
committee. Join the list, or view the web archive at:</p>
<p><a
href="http://lists.linuxcare.com/linux-cert-corprel/threads.html">http://lists.linuxcare.com/linux-cert-corprel/threads.html</a></p>
<p>The CorpRel committee will be working on a proposal to send to the
Board.</p>
<p>5. HELP WITH OUR PUBLICITY WATCH</p>
<p>With so many information technology publications out there - both in print
and on the web, it's next-to-impossible to stay up-to-date on what's being
said all over the place about Linux certification. We'd like your help.
When you see an article (either in print or online) about Linux certification,
can you please send us the info (article title, publication, date, URL if on
the web). Either send it directly to "linux-cert-pr" if you are a member of
that list (if not, consider joining!) or email it to Evan (<a
href="mailto:evan@lpi.org">evan@lpi.org</a>)</p>
<p>You can see the list of what has been posted at:</p>
<p><a
href="http://lists.linuxcare.com/linux-cert-pr/threads.html">http://lists.linuxcare.com/linux-cert-pr/threads.html</a></p>
<p>Messages sent to linux-cert-pr appear on the archive within an hour.</p>
<p>6. WRITE OR SPEAK ABOUT LPI AND LINUX CERTIFICATION</p>
<p>To date, much of the writing and speaking about LPI and our efforts to
create a Linux certification program has been by members of the Steering
Committee such as Evan and I. But please know that we are not at all
exclusive about that and would encourage others to help out with writing
and/or speaking about LPI and Linux certification.</p>
<p>Many web sites are looking for people to write articles and we'd love to
see more articles out there about Linux certification and LPI. If you know of
a site looking for articles, please go ahead and write one. We'll be glad
to provide some information or assistance if you need it. Also, if you'd
like to write articles, drop us a note and we may be able to steer you to
places where they are looking for writers (usually the online sites are
looking for writers who will write for free).</p>
<p>Print publications are good, too. For instance, I had an article in the
June ";login:" published by USENIX and then an article in the July "Linux
Journal." Scott Murray &amp; Alan Mead are planning to submit an article on
their survey process to a psychometrics journal. Articles might be
appropriate for local or regional newsletters for training organizations, user
groups, etc.</p>
<p>Also, if you're interested in speaking to local groups, we will soon be
making some presentations available online (in Applixware format so far,
probably HTML, too) that you could use. For instance, Faber Fedor recently
spoke to a local association of technical educators in his state.</p>
<p>If you are interested in writing or speaking, please feel free to contact
either Evan (<a href="mailto:evan@lpi.org">evan@lpi.org</a>) or I (<a
href="mailto:dan@lpi.org">dan@lpi.org</a>). Feel free, too, to go ahead and
just write... we'll be glad to look over articles if you'd like us,
too.</p>
<p>7. IF IN GERMANY, HELP WITH THE NEW GERMAN "CHAPTER"</p>
<p>As described further down in this article, there is now an effort underway
to create a German "Chapter" of LPI that would help translate informational
materials into German and also write/speak about LPI certification within
Germany and in the German language. More details will be available soon, but
in the meantime, please contact Mark Semmler at: <a
href="mailto:mark.semmler@frontsite.de">mark.semmler@frontsite.de</a></p>
<p>Please read the <a href="#German">text below</a> for more information.</p>
<p>8. JOIN OUR MAILING LISTS</p>
<p>If you haven't joined one of our committee mailing lists, where more of the
work is going on, visit:</p>
<p><a

<h2><a name="Board">Board Membership Changes</a></h2>
<p>After being on our Steering Committee list since its formation, Josh Arnold
recently indicated he needed to step aside because of other committments. He
intends to stay subscribed to the mailing lists and hopes to be able to
contribute to the Program Committee on an ongoing basis. We thank Josh for
his willingness to step forward and help lead, and we do hope he can continue
to be involved as our efforts move on.</p>
<p>With Josh's departure, the Steering Committee/Board took some time to
identify what roles we needed to fill. We next considered who had contributed
to the LPI effort in some meaningful way and spoke to a couple of people
about joining the Board. At this time, we are pleased to announce Jared
Buckley's addition to the LPI Board. Jared stepped forward to lead the
Naming committee and has been an active contributor to several of our mailing
lists. During the day, Jared works for Texas Instruments in Dallas, TX, where
he supports the WAN and administers several covert Linux servers.</p>
<p>Please join us in welcoming Jared to the Board. His new responsibilities
will include helping create newsletters such as this and generally helping to
coordinate volunteer participation. He may be reached online at
"jaredb@ti.com". (He will soon have an "lpi.org" address as well.)</p>
<p></p>
<hr>
<h2><a name="d">Completed Level 1 Objectives</a></h2>
<p>Over the last month, a dedicated group of participants worked to finalize
the objectives for the first exam (T1) and the generic portion of the second
group of exams (T2). These objectives were finalized in early June, allowing
courseware developers and publishers to know what they should orient their
materials toward.</p>
<p>We will soon have a web page online providing a simple list of the final
objectives. In the meantime, you can visit our management system at:</p>

<h2><a name="German">German "chapter" forming</a></h2>
<p>When I knew I was going to be in Munich teaching some classes, (yes,
Linuxcare expects me to actually do some work for them, too, and not just work
on LPI!) I sent out a note asking if anyone would be interested in meeting.
Juergen Off from frontsite AG contacted me and we arranged to meet.</p>
<p>Juergen and his colleague Mark Semmler brought me to the Biergarten in the
beautiful Englisher Garten part of Munich and we had a very enjoyable evening
eating, drinking beer and flipping somewhat randomly between talking in
English and German.</p>
<p>Along the way, Juergen and Mark commented that there really wasn't much
discussion of Linux certification within the German media and Linux community.
They asked "what can we do to help spread the word here in Germany?" As we
talked, Juergen suggested the idea of having a local German "chapter" of
LPI... all three of us were intrigued by the idea and discussed the idea at
length.</p>
<p>After that night, we exchanged more email and also shared the idea with
others we knew in Germany. The others at frontsite AG were quite interested,
as were the folks at SuSE with whom I communicated.</p>
<p>The LPI Board considered the subject and we, too, thought it was a great
idea and gave the go-ahead to the frontsite AG folks to start a discussion and
make it happen. Since there was so much interest, we thought this German
chapter would be a great pilot program to see how this idea can work.</p>
<p>Mark Semmler wasted little time and sent off a note to the "linux-cert"
mailing list asking if people would be interested. His full message, which
includes his German text, can be found at:</p>
<p><a
href="http://lists.linuxcare.com/linux-cert/msg00038.html">http://lists.linuxcare.com/linux-cert/msg00038.html</a></p>
<p>Since this newsletter is going to a global audience and is written in
English, I'm including only Mark's English text below so that you get a sense
of what he and the others are proposing.</p>
<p>I know already there is great interest in meeting at the upcoming LinuxTag
in Kaiserslautern, Germany on June 26th &amp; 27th. It will be great to see
what comes out of discussions there.</p>
<p>Please contact Mark at "<a
href="mailto:mark.semmler@frontsite.de">mark.semmler@frontsite.de</a>" if you
are interested in becoming involved with this effort.</p>

<pre>Subject: LPI Germany?!
Date: Thu, 24 Jun 1999 01:32:19 +0200
From: Mark Semmler &lt;mark.semmler@frontsite.de></pre>
<pre>&lt;German text snipped></pre>
<pre>Hello everybody!</pre>
<pre>We are tracking very interested since a couple of weeks the mailinglists of
the LPI and we are just fascinated by the thoughts and the dynamic of this project.</pre>
<pre>During a meeting with Dan York early this month in Munich, the thought was born,
to create a german-speaking chapter of the LPI.</pre>
<pre>The goals of this "chapter" should be:</pre>
<pre> - promote the idea of LPI Linux certification through local
media, conferences, publications, etc.</pre>
<pre> - maintain German-language mailing lists and a web site
(in German) to promote discussion of Linux certification issues</pre>
<pre> - translate English LPI marketing and information materials into
German for distribution within Germany</pre>
<pre> - assist in identifying people/companies that can perform
the translation of exam items (questions) into German</pre>
<pre> - organize discussion groups and local meetings that bring
together key players within the German training and larger
information technology industry to move Linux certification
forward</pre>
<pre> - communicate ideas from the German-language discussion groups/lists
back to the English-language discussion groups/lists</pre>
<pre> - translate LPI news releases into German and distribute them
to appropriate German news media</pre>
<pre>I'm sure there will be other tasks which develop as well.</pre>
<pre>This chapter should be organized like the LPI.
Means: non-profit and independent.</pre>
<pre>We offer to host and to maintain the mailinglists and the webspace for
such a project on our servers. The domainname could be "(www.)de.lpi.org" and/or "(www.)german.lpi.org".</pre>
<pre>Who is interested?</pre>
<pre>Juergen Off, Mark Semmler, Jens Kiefer, Heiko Franssen, Thorsten Linstead</pre>

<h2><a name="Logo"><a name="Logo1">Logo Contest Results</a></a></h2>
<p>Those of you who have followed our web site and the past newsletters are
aware of the Logo Contest that we ran for quite some time. There were some
pretty amazing entries submitted by some very talented people. We set up a
poll on our web site to get some idea of what viewers thought. In the end,
the simplicity of Jorge Otero's design seems to have captured people's
attention. You can check out all the designs at:</p>
<p><a

<p>The LPI Board has not made a formal decision yet, but is leaning strongly
toward using Mr. Otero's design.</p>
<p>Thank you to <strong>all</strong> the people who took time out of their day
to create some artwork for us. It all is great!</p>

<h2><a name="Mailing">Mailing List Archives</a></h2>
<p>FYI, archives of all LPI mailing lists can be found at:</p>
<p><a href="http://lists.linuxcare.com/">
http://lists.linuxcare.com/</a></p>
<p>Messages posted to an LPI list are posted to the web archives within an
hour. Note that we are still working on restoring the historical archives
after a server crash, so they only contain recent information.</p>
<p>There is, however, an archive of the "linux-cert" mailing list going back
to last November when this all began. It is still active and can be found
at:</p>
<p><a href="http://linux.codemeta.com/archives/linuxcert_archive/">
http://linux.codemeta.com/archives/linuxcert_archive/</a></p>
<p>but again, because most of the activity has moved to the committee mailing
lists and the web site, the archive does not reflect the full range of LPI
activity going on today.</p>
<p>This second archive is now searchable at:</p>
<p><a href="http://linux.codemeta.com/archives/archive_search.html">
http://linux.codemeta.com/archives/archive_search.html</a></p>
<p>On the page, you must choose "Linux Certification" from the select button
in order to search our archive.</p>
<p></p>
<p>We also just recently added our mailing lists to the archives at <a

<h2><a name="Final">Final Thoughts</a></h2>
<p>We're nearing the end of the first phase of our development. By the end of
this month, people should be taking our first beta exam in VUE testing centers
all around the globe. Our psychometricians will be analyzing data. Others
will be finalizing our second (T2) set of exams. Another group will be
working on translation of the exams into other languages. Yet another group
will be starting work on the objectives for the Level 2 exams. Marketing
programs will be underway.. we'll be gearing up for LinuxWorld in San Jose in
August... it's going to be a crazy and exciting time!</p>
<p>I hope you'll visit our web site at www.lpi.org and join in the fun and
excitement. It's only through the power of MANY people working together that
we've been able to make this happen!</p>
<p>Thank you all for your continued support.</p>

<center><font color="maroon"><h3>Introduction</font></h3></center>
<p>There is a tension in the Linux community between developers, who tend to
be comfortable with their text editors and mark-up formatting systems, and
users who want the sort of word processor common in the Mac and Windows
worlds. This tension periodically sparks discussions in newsgroups and
mailing lists, but an Open Source project has yet to produce a finished, fully
usable word processor. The release of GPLed source last year for the Maxwell
word processor failed to draw enough programmer interest to result in an
ongoing and dynamic project to complete the program, possibly because of
Maxwell's reliance on the Motif widget set.
<p>Of course the commercial products StarOffice, WordPerfect and Applix Words
are available for Linux. These are large applications; I'm under the
impression that many users desire something quick to load and less complex, a
word processor suitable for formatted business letters and other shorter
documents. Another factor mitigating against the above commercial
applications is the lack of community involvement. I've noticed that
closed-source applications don't seem to generate mailing list and newsgroup
postings as readily as do various free software projects. I rarely write
directly to developers involved in the various free software projects I
follow, but I know who they are and if the need happened to arise I
wouldn't hesitate to make contact. Free software projects typically attract a
secondary level of co-developers and skilled users who often frequent the
various net forums answering questions and providing assistance.
<p>It has been suggested that writing a good word processor is such a
difficult task that it is beyond the capabilities of an Open Source
development process. More likely, I think, is that a large enough group of
programmers ardently desiring such an application just hasn't ever coalesced.
Perhaps this sort of project is suited for a hybrid approach, one involving
both a commercial firm and independent free-software programmers. AbiSource,
Inc. is giving this idea a try.
<center><font color="maroon"><h3>AbiWord So Far</h3></font></center>
<p>Is it possible for an ambitious Open Source project to thrive and produce useful
results under the sponsorship of a for-profit corporation? The Mozilla
project is one such undertaking. After over a year of source availability much
has been accomplished but the current binary releases, while intriguing,
aren't yet as usable as the current releases of Netscape Communicator. The
bulk of the new code still seems to be primarily coming from paid Netscape
programmers. This might indicate that free software programmers prefer
working on projects which aren't under a corporate aegis; another possible
reason is the sheer size and complexity of the Mozilla code-base. Many
programmers might lack the time and/or skill to comprehend such a project, and
starting from scratch with a relatively new widget-set (GTK) must further
increase the difficulty.
<p>The programmers who started AbiSource, Inc. don't seem to be daunted by the
dearth of efforts to mix business with Open Source from the very beginning of
a project. Mozilla already had a massive source tree when its development was
opened to the outside world last year, while Eric Allman's Sendmail business
followed years of non-profit and open development; Eric had written a proven and
widely-used piece of software before he formed a company to provide service
for corporate users of Sendmail.
<p>It should be kept in mind that these are still early days in the
intersection of the free software and business worlds. Another year or so of
experimentation with the various trials and ventures ought to make evident which
approaches have managed to make money without driving away the developers and
users in the free software community. AbiSource is a new company gambling
that its ideas will prove viable and useful.
<p>AbiSource's goal is to provide basic Open Source business applications for
Linux, Windows, and BeOS users. Their idea is to give their applications away
and charge for service and customization. Abi's first product is a GTK-based
word processor, AbiWord. Outside programming help is welcomed and all of the
usual paraphernalia of an Open Source project, such as mailing lists, CVS
servers, and bug-reporting mechanisms, are available from the AbiSource
web-page,
<a href="http://www.abisource.com">http://www.abisource.com</a>.
The number of non-Abi volunteer programmers contributing code isn't
mentioned on the site, but I believe that the completion of the BeOS port
was largely due to outside Be programmers.
<p>It's interesting that while the source code is under the GPL and thus freely
available and modifiable, the names AbiSource and AbiWord are copyrighted.
This is intended to protect whatever reputation and name-recognition the
company might gain if their services become popular.
<p>The most significant difference between AbiWord and nearly every other
word processor available is the nature of the native file format. An *.abw file is
written in XML and thus is also in ASCII format; the files can be read by any
text editor. This is quite a break with word processor tradition and ensures
that when you write a document with AbiWord you don't run the risk of being
strictly tied to one particular word processor, which may not even run on
machines five years from now. AbiWord can also save in the HTML and RTF
formats, both of which are accessible with word processors such as MS-Word and
WordPerfect. Due to limitations of HTML and RTF some formatting
information is lost (such as the specific fonts used), but attributes such as bold
and italic font styles and tab-settings are retained. If XML really does
become a widely-used and open data-format (as its proponents predict)
AbiSource might be in a good position to gain users and clients.
<p>Many Linux users would like to be able to read MS-Word files with a Linux
word processor. StarOffice, Applix Words, and WordPerfect all come with
filters for the ubiquitous format; these filters usually work well with simple
documents but more complex documents with embedded macro routines are another
matter. AbiSource has chosen to avoid this particular can of worms; the RTF
support should ensure that simply formatted files can be exchanged with Word
users.
<p>Linux users and developers in academia, with its strong unix traditions,
have less of a need to be able to deal with MS-Word files than do the growing
numbers of users coming to Linux from the &quot;real&quot; world, the larger
world of commerce and corporations. Until the nearly universal usage of the
MS-Word format for even the simplest documents begins to decline, alternative
word processors will have to struggle to gain market-share. The fact that
AbiWord is free should be of some help, though there still exists a common
idea that free software is somehow suspect.
<p>With the release of 0.7 (and most recently 0.7.1) AbiSource began to make
binaries freely available on their web-site and have even pressed CDs which
are available at a nominal price. This would seem to indicate that the program has
reached a state of usability. I've been trying out the latest release;
it's serviceable but basic and seems to be stable. I've not had it crash
once. Few of the paragraph and document formatting functions have been
enabled at this point, but font-changes and tab-settings work well. Zooming
(enlarging the apparent size of the document on the screen) is enabled. The
fonts can be changed either from a drop-down selector or with the spiffy GTK
font-selector dialog-box. Here is a screenshot of version 0.7.1:
<p><img alt="AbiWord window" src="gx/ayers/abi.gif" width=690 height=631>
<p>Looks like a normal word processor, doesn't it? Notice the red squiggly
lines beneath certain words; this is supposed to indicate misspelled words. I
have yet to find a way to turn it off. AbiWord comes with its own dictionary,
but there doesn't yet seem to be a way to spell-check a document. Many of the
menu-items are non-functional. Clicking on one of these summons a message-box
stating that &quot;the [function] dialog hasn't been implemented yet&quot;
followed by a pointer to lines in the source file which need the work, a
thoughtful hint to a prospective code contributor.
<p>If you give AbiWord a try, create a new file with a few lines of content,
save it, then examine the resultant <b>*.abw</b> file with a text editor. Your
content will be readable in this file, with surrounding XML tags indicating
formatting specifications. As an example, here is the last line of the file
used in the above screenshot:
<p>
<pre><code>&lt;p props="line-height:1.5; margin-right:1.8125in"&gt;
&lt;c props="font-family:Century Schoolbook; font-size:14pt; font-style:normal;
font-weight:normal"&gt;Variable line-spacing is now working. This is set now for
one and one-half rather than single-spacing.&lt;/c&gt;&lt;/p&gt;
</code></pre>
<p>As you can see, the formatting tagging is comprehensible and could even be
modified &quot;by hand&quot;, in an editor rather than in the
word processor. The actual content is accessible, a welcome difference from
the usual binary word processor format in which the content is immersed in a
sea of unreadable binary symbols.
<p>The source distribution contains some interesting examples of
<b>*.abw</b> files but these files were omitted from the binary packages.
<p>In the Linux version, and I assume in the Windows and BeOS versions as
well, printing is handled by the existing print system. On my system the file
seems to be converted to Postscript format, then is passed to Ghostscript for
processing by my print filter. AbiWord uses standard Postscript Type 1 fonts,
but for some reason they need to be located in an Abi-specific directory.
Several standard fonts are supplied with AbiWord, but more can be added as
long as both the <b>*.afm</b> and the <b>*.pfa</b> files are supplied for each
font. As in standard X Windows font installation, the index file
<kbd>fonts.dir</kbd> must be updated as well.
<hr>
<center><font color="maroon"><h3>Conclusion</h3></font></center>
<p>In its current state AbiWord is useful for writing short, simply formatted
documents, but lack of paragraph and document formatting templates, as well as
the lack of functional image insertion, limit its scope. It seems to me that
AbiSource has developed the base structure of the word processor solidly, and
the hooks for completion of the feature-set are in place in skeletal form and
just need to be fleshed out. The decision to use an XML file format should
appeal to users who would like to use something other than the exclusive
binary file-formats of typical word processors. Whether AbiSource will be
able to keep the development process alive until revenue is generated remains
to be seen, but at least the source code will remain available should they fail.

I want to give a <FONT SIZE=+2><STRONG>big thanks</STRONG></FONT> to our
authors this month for giving us such a substantial issue. This issue has
almost twice as many articles as last month, and I learned a thing or two
from some of them.
<P> This issue is a little milestone for me. It marks my first time publishing
an ezine without outside help.
<P> Dealing with the one letter where we didn't have a common language to
communicate with got me thinking about my interest in
<STRONG>Esperanto</STRONG>. Because if we all had a common, simple auxiliary
language to fall back on (one much easier to learn than English!), these things
wouldn't happen. Are there any <EM>Gazette</EM> readers who speak Esperanto?
If so and you'd like to chat, write me. <EM>Cxu estas iuj ajn legantoj je la
