Introduction</A +></H1 +><BLOCKQUOTE +><P +>“In the beginning, the file was without + form, and void; and emptiness was upon the face of the bits. + And the Fingers of the Author moved upon the face of the + keyboard. And the Author said, Let there be words, and there + were words.”</P +></BLOCKQUOTE +><P +>This manual, the Linux System Administrators' Guide, + describes the system administration aspects of using Linux. + It is intended for people who know next to nothing about system + administration (as in ``what is it?''), but who have already + mastered at least the basics of normal usage. This manual also + doesn't tell you how to install Linux; that is described in the + Installation and Getting Started document. See below for more + information about Linux manuals.</P +><P +>System administration is all the things that one has to + do to keep a computer system in a useable shape. It includes + things like backing up files (and restoring them if necessary), + installing new programs, creating accounts for users (and deleting + them when no longer needed), making certain that the filesystem + is not corrupted, and so on. If a computer were, say, a house, + system administration would be called maintenance, and would + include cleaning, fixing broken windows, and other such things. + System administration is not called maintenance, because that + would be too simple. + + <A +NAME="AEN38" +HREF="#FTN.AEN38" +>[1]</A +> + + </P +><P +>The structure of this manual is such that many of the + chapters should be usable independently, so that if you need + information about, say, backups, you can read just that chapter. + This hopefully makes the book easier to use as a reference manual, + and makes it possible to read just a small part when needed, + instead of having to read everything. However, this manual is + first and foremost a tutorial, and a reference manual only as + a lucky coincidence.</P +><P +>This manual is not intended to be used completely by itself. + Plenty of the rest of the Linux documentation is also important + for system administrators. After all, a system administrator is + just a user with special privileges and duties. A very important + resource are the manual pages, which should always be consulted + when a command is not familiar.</P +><P +>While this manual is targeted at Linux, a general principle + has been that it should be useful with other UNIX based operating + systems as well. Unfortunately, since there is so much variance + between different versions of UNIX in general, and in system + administration in particular, there is little hope to cover + all variants. Even covering all possibilities for Linux is + difficult, due to the nature of its development.</P +><P +>There is no one official Linux distribution, so different + people have different setups, and many people have a setup they + have built up themselves. This book is not targeted at any + one distribution, even though I use the Debian GNU/Linux system + almost exclusively. When possible, I have tried to point out + differences, and explain several alternatives.</P +><P +>I have tried to describe how things work, rather than just + listing ``five easy steps'' for each task. This means that there + is much information here that is not necessary for everyone, + but those parts are marked as such and can be skipped if you + use a preconfigured system. Reading everything will, naturally, + increase your understanding of the system and should make using + and administering it more pleasant.</P +><P +>Like all other Linux related development, the work was + done on a volunteer basis: I did it because I thought it might + be fun and because I felt it should be done. However, like all + volunteer work, there is a limit to how much effort I have been + able to spend, and also on how much knowledge and experience + I have. This means that the manual is not necessarily as good + as it would be if a wizard had been paid handsomely to write it + and had spent a few years to perfect it. I think, of course, + that it is pretty nice, but be warned.</P +><P +>One particular point where I have cut corners is that I + have not covered very thoroughly many things that are already + well documented in other freely available manuals. This applies + especially to program specific documentation, such as all the + details of using <B +CLASS="COMMAND" +>mkfs</B +>}. I only describe the + purpose of the program, and as much of its usage as is necessary + for the purposes of this manual. For further information, + I refer the gentle reader to these other manuals. Usually, + all of the referred to documentation is part of the full Linux + documentation set.</P +><P +>While I have tried to make this manual as good as possible, + I would really like to hear from you if you have any ideas on + how to make it better. Bad language, factual errors, ideas for + new areas to cover, rewritten sections, information about how + various UNIX versions do things, I am interested in all of it. My + contact information is available via the World Wide Web at <A +HREF="http://www.iki.fi/liw/mail-to-lasu.html" +TARGET="_top" +>http://www.iki.fi/liw/mail-to-lasu.html</A +>. + </P +><P +>Many people have helped me with this book, directly or + indirectly. I would like to especially thank Matt Welsh for + inspiration and LDP leadership, Andy Oram for getting me to work + again with much-valued feedback, Olaf Kirch for showing me that it + can be done, and Adam Richter at Yggdrasil and others for showing + me that other people can find it interesting as well.</P +><P +>Stephen Tweedie, H.~Peter Anvin, R\'emy Card, Theodore + Ts'o, and Stephen Tweedie have let me borrow their work (and + thus make the book look thicker and much more impressive): + a comparison between the xia and ext2 filesystems, the device + list and a description of the ext2 filesystem. These aren't + part of the book any more. I am most grateful for this, and + very apologetic for the earlier versions that sometimes lacked + proper attribution.</P +><P +>In addition, I would like to thank Mark Komarinski for + sending his material in 1993 and the many system administration + columns in Linux Journal. They are quite informative and + inspirational.</P +><P +>Many useful comments have been sent by a large number + of people. My miniature black hole of an archive doesn't let + me find all their names, but some of them are, in alphabetical + order: Paul Caprioli, Ales Cepek, Marie-France Declerfayt, + Dave Dobson, Olaf Flebbe, Helmut Geyer, Larry Greenfield and + his father, Stephen Harris, Jyrki Havia, Jim Haynes, York Lam, + Timothy Andrew Lister, Jim Lynch, Michael J.
