I find the most useful tool in the attempt to identify services and their
|
||
parents to be <TT>netstat -ple</TT> (process, listening, extended info). This
|
||
provides a table of listening sockets, the processes that own them, and
|
||
the uid of the process.

Hi,
|

</STRONG></P>
|
||
<P><STRONG>
|
||
I need to authenticate a user entering a linux os.
|
||
</STRONG></P>
|
||
<P><STRONG>
|
||
I get from the user a username and a password and need to cross it with
|
||
the <TT>/etc/passwd</TT> file.
|
||
</STRONG></P>
|
||
<P><STRONG>
|
||
How do I cross the password with the existing one ? (How can I enctypr the
|
||
password the user entered ?)

</STRONG></P>

I presume what you're trying to ask is something like: "how can
|
||
my custom script or application determine if a user has given me
|
||
the password as would be checked by the system?"

</BLOCKQUOTE>
|

|

The short answer is that your program should use the getpwent(3)
|
||
and the crypt(3) library calls.

That is a bit of an oversimplification but here's a bit more detail:

</BLOCKQUOTE>
|

<BLOCKQUOTE><BLOCKQuote>
|
||
Technically you don't "encrypt" the password, you "hash" it and
|
||
compare your result with the one that's stored in the <TT>/etc/passwd</TT>,
|
||
or the <TT>/etc/shadow</TT> file, or the one that's returned by NIS, etc.

In your answer to Gaurav you didn't mention TurboPrint. I found the
|

current version has full support for my Epson Photo 700 and most
|

other Epson printers as well. I now have full photo quality printing
|

under Linux. Support for other printers is growing daily so keep

checking back if you don't see it the first time.

<blockquote><em>The trick is that each "255" octet is 8 bits. The number

16, still not enough, need 4 bits 4 more! See it's really just that

many 1's counted from the left... which is to say from the

to "leak through" and establish the network address... the 0's

block or "mask" all the local addresses off.

Hi! I would like to access my graphics Linux desktop from my Windows box; I
|
||
was able to do it using a software called Reflection (I guess you know it), is
|
||
there any (free) software with the same capabilities of Reflection?

You could also try VNC. If you run a VNC Server on your Linux Machine and a VNC
|
||
client on your Windows box, you can get a graphical Login (xdm, gdm, kdm) on
|
||
your Windows Box. See:

I bought the ActionTec Internal Call Waiting PCI - <EM>not</EM> to be
|

confused with the "56K PCI Pro" which is labelled as a WinModem <TT>-</TT> 'coz
|

it was the <EM>only</EM> one that mentioned Linux support on the box <EM>and</EM>
|

was PCI. From this I assumed it to be a "real" modem.

I haven't actually tried it under Linux yet, but I was impressed to

find the instruction book had more pages (10) devoted to getting it to

work under Linux than for the Windows variants. And there is <EM>no</EM>

mention of having to install special software ... at least none that I

There are separate headings for PPP, <A HREF="http://www.gnome.org/">GNOME</A> Dialer Applet, KPPP,

Kapil Sharma gave in the Oktober issue a few security tips.

One is blocking users from doing su and only allowing the users from group

It works well in virtual terminals. In <A HREF="http://www.kde.org/">KDE</A> however it is now impossible to su.

Authentication rejects now always the root password.

This also fails in Gnome if I use the default terminal. Try

opening a vanilla xterm <TT>-</TT> I can su if I do it there.

|

The "<TT>-pletter</TT>" option says you're using letter-sized paper (the normal
|
||
page size in the US). Otherwise it will default to the European A4 size.
|
||
If you print A4-formatted pages on letter paper, the rightmost part of
|
||
the content runs off the edge of the page.
|
||
</BLOCKQUOTE>
|
||
<BLOCKQUOTE>
|
||
The "<TT>-pprinter</TT>" option didn't work for me. I assume Matthew was trying
|
||
to select the printer device. According to my lpr manpage, the option
|
||
would be "<TT>-P</TT> printer". "<TT>-p</TT>" filters the input through pr, which isn't
|
||
what we want. (The pr command formats text files.)
