1. Introduction
|
|||
|
|
|||
|
The traditional means of troubleshooting computer-related problems involves
|
|||
|
consulting user's manuals, books, friends - probably enticed with goodies -
|
|||
|
and, when all the former do not yield a solution, calling the technical
|
|||
|
support service of the vendor of the product in question. And, we all know
|
|||
|
pleasant and reliably efficacious the latter stratagem is. Unfortunately,
|
|||
|
this is the norm in the sphere of commercial proprietary products.
|
|||
|
|
|||
|
In contradistinction, Linux, and related distributions, utilities and
|
|||
|
applications software, have largely been developed according to the [http://
|
|||
|
www.opensource.org] Open Source model, wherein developers have used
|
|||
|
electronic communication over the Internet - typically in the form of
|
|||
|
publicly-accessible Mailing Lists - to collaborate with their peers in the
|
|||
|
refinement of the associated source code. Such collaboration has also
|
|||
|
traditionally involved the online publication of user's manuals, lists of
|
|||
|
Frequently-Asked-Questions (FAQ's), knowledge bases, release notes, formal
|
|||
|
guides such as this document (HOWTO's) and tutorials. In addition, users
|
|||
|
often assist others through the forum of Usenet and other newsgroups and the
|
|||
|
posted messages are readily accessible in the form of searchable archives.
|
|||
|
These Linux-related newsgroups are renowned for their high level of user
|
|||
|
participation. In significant measure, Linux may be considered a product of
|
|||
|
the Internet.
|
|||
|
|
|||
|
Considered together, these resources enable access to a large,
|
|||
|
ever-expanding factual database, and my intent is to encourage and direct the
|
|||
|
reader to utilize these repositories when faced with an issue not addressed
|
|||
|
in the documentation that is included with each distribution of Linux. Linux
|
|||
|
veterans who assist newcomers through the forum of Usenet soon become aware
|
|||
|
of the frequency with which certain technical questions are repeatedly posted
|
|||
|
- questions the answers to which are readily available in one or more of the
|
|||
|
existent online repositories. So, to diminish the likelihood of being
|
|||
|
"flamed" in response to your posted question on Usenet or irc, read further!
|
|||
|
|
|||
|
Armed with a browser, Linux users may rapidly become adept at
|
|||
|
troubleshooting their systems. The key is knowing how and where to look. My
|
|||
|
objective is to guide the user - particularly the Linux newbie - in this
|
|||
|
quest.

1.5. Document history
|
|||
|
|
|||
|
Howard Mann conceived and formulated the first version of this HOWTO. He
|
|||
|
kept managing and updating it until version 1.3. Maintainership was then
|
|||
|
taken over by Jean-Philippe Gu<47>rard, who is now in charge of this document.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
2. Frequently-Asked-Questions (FAQs)
|
|||
|
|
|||
|
Users of Internet Newsgroups and Mailing lists soon discovered that some
|
|||
|
basic questions were being asked over and over again. To provide an answer to
|
|||
|
these questions, and to avoid them being repeated continually, FAQs were
|
|||
|
developed, listing the most classical questions and their agreed answers.
|
|||
|
|
|||
|
A list of FAQs is also a traditional accompaniment to Linux-related
|
|||
|
software. The FAQ is the first document to peruse when troubleshooting a
|
|||
|
particular application. It provides answers to typical questions, and is a
|
|||
|
good place to start troubleshooting a specific problem. In addition, FAQs
|
|||
|
exist for Linux distributions, window managers, and the so-called desktop
|
|||
|
environments (KDE and Gnome).
|
|||
|
|
|||
|
A FAQ is typically provided online by the developers of the product in
|
|||
|
question, and enterprising users sometimes host an "unofficial" FAQ as well.
|
|||
|
Search for the latter with an Internet search engine.
|
|||
|
|
|||
|
For Linux newbies, I provide links to two FAQs that collectively address
|
|||
|
many of the questions posted to the Usenet newsgroups:
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A> [http://www.tldp.org/FAQ/Linux-FAQ/] The Linux FAQ
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A> The Linux Kernel mailing list FAQ
|
|||
|
|
|||
|
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
3. Online Support Sections
|
|||
|
|
|||
|
These sections are typically found at the websites of Linux distributions,
|
|||
|
and often contain a variety of helpful documents with information not easily
|
|||
|
encompassed within a FAQ. This is the second place to go when troubleshooting
|
|||
|
a problem. Look for sections with one or more of the following titles:
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A> Installation Support
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A> Knowledge or Solutions Databases

<EFBFBD><EFBFBD>*<2A> Technical Guides
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A> White Papers
|
|||
|
|
|||
|
|
|||
|
Some websites provide a site search engine that will facilitate your quest
|
|||
|
for a solution.
|
|||
|
|
|||
|
If you have a problem with a newly installed distribution, look here first
|
|||
|
as bugs and their fixes are typically posted here. You may find a detailed
|
|||
|
guide that will help you accomplish a task such as upgrading your kernel or
|
|||
|
the version of the X Window System you are using.
|
|||
|
|
|||
|
I have often been able to solve problems with my Linux distribution by
|
|||
|
looking into the bug report database, and finding that another user already
|
|||
|
has offered a solution to this issue.
|
|||
|
|
|||
|
I recommend you spend some time at the website of the distribution you are
|
|||
|
using, familiarizing yourself with what is available.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
4. Internet Search Engines
|
|||
|
|
|||
|
I frequently use a Search Engine to retrieve helpful or necessary
|
|||
|
information from the 'net. These engines catalogue pages from commercial,
|
|||
|
personal and academic websites, as well as Mailing Lists and the like.
|
|||
|
|
|||
|
There are several good search engine. It is worthwhile becoming very
|
|||
|
familiar with the operational details of at least one non-directory engine to
|
|||
|
maximize the efficiency and efficacy of your search efforts. You probably
|
|||
|
already have a favorite - I like Google.com, and will discuss it in a little
|
|||
|
more detail.
|
|||
|
|
|||
|
The key to a successful search is to use a good set of keywords. If you're
|
|||
|
getting a specific error message, you might search for its text. Otherwise,
|
|||
|
you need to find a few relevant words describing your problem. Then, by trial
|
|||
|
and error, you should be able to find some pertinent information.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
4.1. Google.com
|
|||
|
|
|||
|
This [http://www.google.com] engine has several novel features that are
|
|||
|
described in its [http://www.google.com/technology/] Google Technology page.
|
|||
|
In particular, the engine often returns the most useful pages first; in fact,
|
|||
|
I have often found that the first listed page contains the information I
|
|||
|
need. Because it caches web pages, it is relatively fast at displaying
|
|||
|
requested items. It has a so-called GoogleScout?? feature, activated by
|
|||
|
clicking on the "similar pages" links, that provides additional relevant
|
|||
|
links with each item returned.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
5. Usenet Newsgroup Archives
|
|||
|
|
|||
|
The ability to search for and retrieve information from archived posts to
|
|||
|
the Linux-related (Usenet) newsgroups represents a powerful means of
|
|||
|
troubleshooting in Linux.
|
|||
|
|
|||
|
Search engines permit one to search the archives by stipulating the forum,
|
|||
|
keywords, authors, dates, language and combinations thereof. Because the
|
|||
|
number of Linux-related newsgroups is large, the likelihood of finding useful
|
|||
|
information is high.
|
|||
|
|
|||
|
The main web site that currently provides access to Usenet archives using a
|
|||
|
search engine is [http://groups.google.com] http://groups.google.com. The
|
|||
|
most effective way to do a search is to use its Advanced Groups Search page.
|
|||
|
|
|||
|
I would like to relate a brief anecdote to demonstrate the efficacy of this
|
|||
|
approach. The first time I attempted to build a kernel, I was presented with
|
|||
|
this error message when I invoked a "make" command:
|
|||
|
make[1]: as86: Command not found
|
|||
|
make[1]: *** [bootsect.o] Error 127
|
|||
|
make[1]: Leaving directory `/usr/src/linux/arch/i386/boot'
|
|||
|
make: *** [zImage]
|
|||
|
Error 2
|
|||
|
|
|||
|
I had no idea what as86 was, but I entered it as the keyword in the Subject
|
|||
|
field of the Advanced Groups Search page at groups.google.com, and was
|
|||
|
presented with a large number of posts from folks who had encountered the
|
|||
|
same problem. Respondents had provided the reason and solution: I did not
|
|||
|
have an assembler/linker necessary to create machine code, and the bin86
|
|||
|
package provided it. I downloaded and installed a RPM package of the latter
|
|||
|
and was on my way. This entire process took about 10 minutes!
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
6. Mailing List Archives
|
|||
|
|
|||
|
As you might expect, there are a very large number of Linux-related Mailing
|
|||
|
Lists that enable developers and users to communicate and collaborate on
|
|||
|
projects. These Lists cover every conceivable aspect of Linux, from the
|
|||
|
technical arcana of kernel development to the relatively unfocused discussion
|
|||
|
of issues at the newbie level. Subscribers to a particular Mailing List are
|
|||
|
generally very knowledgeable in the List's topic, and detailed and useful
|
|||
|
information is often retrievable. The communications are publicly accessible
|
|||
|
through Internet search engines and in the form of online Mailing List
|
|||
|
Archives. You will typically see archived pages when you conduct a search
|
|||
|
using an Internet search engine.
|
|||
|
|
|||
|
Usually, you will not need to look directly in a Mailing List Archive.
|
|||
|
Search engines like Google.com include these archives in their databases. If
|
|||
|
you can't find anything with a search engine, it might be worthwhile to
|
|||
|
browse or search in an appropriate Mailing List.
|
|||
|
|
|||
|
Also, not all Mailing Lists are associated with an online archive, but this
|
|||
|
is increasingly the case. Similarly, not all archives have an associated
|
|||
|
search engine.
|
|||
|
|
|||
|
Initially, try locate the Mailing List Archive you are interested in by
|
|||
|
typing keywords and "mailing list archive" in an Internet search engine.
|
|||
|
|
|||
|
You may also find Mailing List archives at the following locations:
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A> The website of the distribution of Linux you use.
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A> The website of the Window Manager or Desktop Environment you use.
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A> The website dedicated to the application or project in question.
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A> The Mail Archive
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A> Mailing List Archives
|
|||
|
|
|||
|
|
|||
|
This is not a complete listing of archives and you may find additional
|
|||
|
sites with an Internet search engine. But, this should certainly get you
|
|||
|
going.
|
|||

|
|||
|
|
|||
|
7. HOWTOs
|
|||
|
|
|||
|
HOWTOs are detailed reference documents on a specific subject, usually
|
|||
|
following a step-by-step approach. A HOWTO is a good document to help you
|
|||
|
discover a task or a topic you don't know. It will provide you with the basic
|
|||
|
steps and the major references.
|
|||
|
|
|||
|
These documents are particularly useful when you decide to provide or
|
|||
|
access a new service with your Linux system, or when you embark on a
|
|||
|
technically complex project. For example, you may have the option of
|
|||
|
accessing the 'net with a DSL or Cable Modem service - excellent guides are
|
|||
|
available in the form of HOWTOs.
|
|||
|
|
|||
|
Authors of these documents often include references and links to sites that
|
|||
|
they have found useful. You may find the information you need at one of these
|
|||
|
hyperlinked sites rather than in the HOWTO itself.
|
|||
|
|
|||
|
To find HOWTOs, the first place to go is the [http://www.tldp.org] Linux
|
|||
|
Documentation Project (LDP). The LDP includes a HOWTO Index Page that I
|
|||
|
suggest you bookmark in your browser.
|
|||
|
|
|||
|
These HOWTOs are written by Linux users and are periodically updated by the
|
|||
|
authors. Many authors provide the latest version at a personal website and a
|
|||
|
hyperlink to the latter is typically provided in the document. This version
|
|||
|
may be newer than the one available at the LDP website.
|
|||
|
|
|||
|
Note also that other HOWTOs are available, the authors of which have not
|
|||
|
submitted them to the LDP. It is definitely worthwhile trying to find these
|
|||
|
with an Internet search engine, using the "howto" keyword.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
8. Online User's Manuals
|
|||
|
|
|||
|
Some of the major Linux distributions, Window Managers and Desktop
|
|||
|
Environments publish their user's manual online. If the entire manual is not
|
|||
|
online, installation and configuration guides are typically found at the
|
|||
|
relevant website. This also applies to major applications like the Gimp (GNU
|
|||
|
Image Manipulation Program) or Apache.
|
|||
|
|
|||
|
So, for those users who do not have the printed manual, a wealth of
|
|||
|
installation and configuration guidance is generally available online.
|
|||
|
-----------------------------------------------------------------------------

9. Online Unix References and Tutorials
|
|||
|
|
|||
|
As Linux is a Unix-like operating system, a general familiarity with
|
|||
|
fundamental Unix concepts such as the Unix directory hierarchy and file
|
|||
|
permissions is essential. Fortunately, there are many Unix tutorials online
|
|||
|
that collectively cover everything a user might need to know to use Linux. I
|
|||
|
suggest you bookmark the following as an online reference library:
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A> The Wikipedia Unix article is a good place to start. It includes an
|
|||
|
Unix history, explains some Unix concepts and includes an explanation of
|
|||
|
basic commands and some relevant links.
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A> Eric S. Raymond's The Unix and Internet Fundamentals HOWTO is a good
|
|||
|
document to learn about the Unix concepts.
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A> The UNIX Tutorial for Beginners of the University of Surrey is a good
|
|||
|
step by step tutorial for beginners.
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A> The Command and Shell User's guide from Digital Equipment Corporation
|
|||
|
is an excellent guide to the Unix Operating System. Bookmark the Index
|
|||
|
Page linked there as an online reference.
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A> [http://star.pst.qub.ac.uk/help/unixhelp/] UNIXhelp is mirrored on many
|
|||
|
servers around the world. It is a useful resource for newbies.
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A> Introduction to Unix also contains a useful Unix Command Summary page
|
|||
|
with brief, but useful, explanations of commonly used Unix commands.
|
|||
|
|
|||
|
<EFBFBD><EFBFBD>*<2A> Unix is a Four Letter Word... is another resource suitable for newbies.

10. Miscellaneous Resources
|
|||
|
|
|||
|
In this section, I provide a number of links to websites that I have found
|
|||
|
useful while learning to use Linux. This is an eclectic collection, but keep
|
|||
|
these handy.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
10.1. Release Notes and Available Documentation related to the X Window
|
|||
|
Server
|
|||
|
|
|||
|
Depending on the X Window Server your distribution is using, you will need
|
|||
|
to look at either the XFree86 website or the X.Org Foundation website.
|
|||
|
Whenever you have trouble with your X environment, peruse the notes
|
|||
|
applicable to your videocard and chipset. These typically provide details
|
|||
|
about the configuration of the X Window System relative to your card, and
|
|||
|
will enumerate any "options" you have to include in the XF86Config file that
|
|||
|
governs X.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
10.2. GNU Software and Manuals
|
|||
|
|
|||
|
Many important programs that are frequently utilized by the Linux user are
|
|||
|
GNU utilities - for example, the tar (archive) and gzip (compression)
|
|||
|
programs. Descriptions of these programs are located at the [http://
|
|||
|
directory.fsf.org/] FSF Free Software Directory where many Online Manuals may
|
|||
|
also be found.
|
|||
|
|
|||
|
These manuals typically provide a lot more information than is found in the
|
|||
|
corresponding man page on your system. For example , compare the man page and
|
|||
|
online manual for the tar utility.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
10.3. The Free On-line Dictionary of Computing
|
|||
|
|
|||
|
The Free On-line Dictionary of Computing (FOLDOC) is a huge encyclopedia of
|
|||
|
computing terms and concepts, maintained by Denis Howe. It has very detailed
|
|||
|
articles, with a lot of cross references. It's a very good reference to
|
|||
|
understand anything related to computing.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
10.4. An online dictionary of computer and technology terms
|
|||
|
|
|||
|
The [http://www.pcwebopedia.com/] PC Webopedia consists of a large online
|
|||
|
dictionary of computer-related terms and a search engine that provides links
|
|||
|
to documents that discuss each item in more detail. For example, I used this
|
|||
|
site to learn the differences between ISA and PCI buses.
|
|||

11. Concluding Comments
|
|||
|
|
|||
|
If you are a Linux newbie, you may want to create a Troubleshooting folder
|
|||
|
in your browser's bookmark list, into which you put the hyperlinks I have
|
|||
|
included in this document, as well as those pertinent to the distribution of
|
|||
|
Linux and the Window Manager or Desktop Environment you use.
|
|||
|
|
|||
|
As you use these links, you will quickly become adept at troubleshooting
|
|||
|
online.
|
|||
|
|
|||
|
Cheers and happy searching!

A. Open Publication License
|
|||
|
|
|||
|
v1.0, 8 June 1999
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
A.1. Requirements on both unmodified and modified versions
|
|||
|
|
|||
|
The Open Publication works may be reproduced and distributed in whole or in
|
|||
|
part, in any medium physical or electronic, provided that the terms of this
|
|||
|
license are adhered to, and that this license or an incorporation of it by
|
|||
|
reference (with any options elected by the author(s) and/or publisher) is
|
|||
|
displayed in the reproduction.
|
|||
|
|
|||
|
Proper form for an incorporation by reference is as follows:
|
|||
|
|
|||
|
|
|||
|
Copyright (c) <year> by <author's name or designee>. This material may
|
|||
|
be distributed only subject to the terms and conditions set forth in the
|
|||
|
Open Publication License, vX.Y or later (the latest version is presently
|
|||
|
available at [http://www.opencontent.org/openpub/] http://
|
|||
|
www.opencontent.org/openpub/).
|
|||
|
|
|||
|
The reference must be immediately followed with any options elected by the
|
|||
|
author(s) and/or publisher of the document (see section VI).
|
|||
|
|
|||
|
Commercial redistribution of Open Publication-licensed material is
|
|||
|
permitted.
|
|||
|
|
|||
|
Any publication in standard (paper) book form shall require the citation of
|
|||
|
the original publisher and author. The publisher and author's names shall
|
|||
|
appear on all outer surfaces of the book. On all outer surfaces of the book
|
|||
|
the original publisher's name shall be as large as the title of the work and
|
|||
|
cited as possessive with respect to the title.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
A.2. Copyright
|
|||
|
|
|||
|

|
|||
|
designee.
|
|||

-----------------------------------------------------------------------------
|
|||
|
|
|||
|
A.3. Scope of license
|
|||
|
|
|||
|
The following license terms apply to all Open Publication works, unless
|
|||
|
otherwise explicitly stated in the document.
|
|||
|
|
|||
|
Mere aggregation of Open Publication works or a portion of an Open
|
|||
|
Publication work with other works or programs on the same media shall not
|
|||
|
cause this license to apply to those other works. The aggregate work shall
|
|||
|
contain a notice specifying the inclusion of the Open Publication material
|
|||
|
and appropriate copyright notice.
|
|||
|
|
|||
|
SEVERABILITY. If any part of this license is found to be unenforceable in
|
|||
|
any jurisdiction, the remaining portions of the license remain in force.
|
|||
|
|
|||
|
NO WARRANTY. Open Publication works are licensed and provided "as is"
|
|||
|
without warranty of any kind, express or implied, including, but not limited
|
|||
|
to, the implied warranties of merchantability and fitness for a particular
|
|||
|
purpose or a warranty of non-infringement.
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
|
|||
|
A.4. Requirements on modified works
|
|||
|
|
|||
|
All modified versions of documents covered by this license, including
|
|||
|
translations, anthologies, compilations and partial documents, must meet the
|
|||
|
following requirements:
|
|||
|
|
|||
|
1. The modified version must be labeled as such.
|
|||
|
|
|||
|
2. The person making the modifications must be identified and the
|
|||
|
modifications dated.
|
|||
|
|
|||
|
3. Acknowledgement of the original author and publisher if applicable must
|
|||
|
be retained according to normal academic citation practices.
|
|||
|
|
|||
|
4. The location of the original unmodified document must be identified.
|
|||
|
|
|||
|
5. The original author's (or authors') name(s) may not be used to assert
|
|||
|
or imply endorsement of the resulting document without the original
|
|||
|
author's (or authors') permission.
|
|||
|
|
|||
|
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
A.5. Good-practice recommendations
|
|||
|
|
|||
|
In addition to the requirements of this license, it is requested from and
|
|||
|
strongly recommended of redistributors that:
|
|||
|
|
|||
|
1. If you are distributing Open Publication works on hardcopy or CD-ROM,
|
|||
|
you provide email notification to the authors of your intent to
|
|||
|
redistribute at least thirty days before your manuscript or media freeze,
|
|||
|
to give the authors time to provide updated documents. This notification
|
|||
|
should describe modifications, if any, made to the document.
|
|||
|
|
|||
|
2. All substantive modifications (including deletions) be either clearly
|
|||
|
marked up in the document or else described in an attachment to the
|
|||
|
document.
|
|||
|
|
|||
|
3. Finally, while it is not mandatory under this license, it is considered
|
|||
|
good form to offer a free copy of any hardcopy and CD-ROM expression of
|
|||
|
an Open Publication-licensed work to its author(s).
|
|||
|
|
|||
|
|
|||
|
-----------------------------------------------------------------------------
|
|||
|
A.6. License options
|
|||
|
|
|||
|
The author(s) and/or publisher of an Open Publication-licensed document may
|
|||
|
elect certain options by appending language to the reference to or copy of
|
|||
|
the license. These options are considered part of the license instance and
|
|||
|
must be included with the license (or its incorporation by reference) in
|
|||
|
derived works.
|
|||
|
|
|||
|
A. To prohibit distribution of substantively modified versions without the
|
|||
|
explicit permission of the author(s). "Substantive modification" is
|
|||
|
defined as a change to the semantic content of the document, and excludes
|
|||
|
mere changes in format or typographical corrections.
|
|||
|
|
|||
|
To accomplish this, add the phrase `Distribution of substantively
|
|||
|
modified versions of this document is prohibited without the explicit
|
|||
|
permission of the copyright holder.' to the license reference or copy.
|
|||
|
|
|||
|
B. To prohibit any publication of this work or derivative works in whole
|
|||
|
or in part in standard (paper) book form for commercial purposes is
|
|||
|
prohibited unless prior permission is obtained from the copyright holder.
|
|||
|
|
|||
|
To accomplish this, add the phrase 'Distribution of the work or
|
|||
|
derivative of the work in any standard (paper) book form is prohibited
|
|||
|
unless prior permission is obtained from the copyright holder.' to the
|
|||
|
license reference or copy.

|||
