Acknowledgments
The Internet is now a household term in many countries. With otherwise
serious people beginning to joyride along the Information Superhighway,
computer networking seems to be moving toward the status of TV sets and
microwave ovens. The Internet has unusually high media coverage, and social
science majors are descending on Usenet newsgroups, online virtual reality
environments, and the Web to conduct research on the new "Internet Culture."
Of course, networking has been around for a long time. Connecting computers
to form local area networks has been common practice, even at small
installations, and so have long-haul links using transmission lines provided by
telecommunications companies. A rapidly growing conglomerate of

Linux Network Administrator's Guide, 2nd Edition: Preface
world-wide networks has, however, made joining the global village a perfectly
reasonable option for even small non-profit organizations of private computer
users. Setting up an Internet host with mail and news capabilities offering
dialup and ISDN access has become affordable, and the advent of DSL
(Digital Subscriber Line) and Cable Modem technologies will doubtlessly
continue this trend.
Talking about computer networks often means talking about Unix. Of course,
Unix is not the only operating system with network capabilities, nor will it
remain a frontrunner forever, but it has been in the networking business for a
long time, and will surely continue to be for some time to come.
What makes Unix particularly interesting to private users is that there has been
much activity to bring free Unix-like operating systems to the PC, such as
386BSD, FreeBSD, and Linux.
Linux is a freely distributable Unix clone for personal computers. It currently
runs on a variety of machines that includes the Intel family of processors, but
also Motorola 680x0 machines, such as the Commodore Amiga and Apple
Macintosh; Sun SPARC and Ultra-SPARC machines; Compaq Alphas; MIPS;
PowerPCs, such as the new generation of Apple Macintosh; and StrongARM,
like the rebel.com Netwinder and 3Com Palm machines. Linux has been
ported to some relatively obscure platforms, like the Fujitsu AP-1000 and the
IBM System 3/90. Ports to other interesting architectures are currently in
progress in developers' labs, and the quest to move Linux into the embedded
controller space promises success.
Linux was developed by a large team of volunteers across the Internet. The
project was started in 1990 by Linus Torvalds, a Finnish college student, as an
operating systems course project. Since that time, Linux has snowballed into a
full-featured Unix clone capable of running applications as diverse as
simulation and modeling programs, word processors, speech recognition
systems, World Wide Web browsers, and a horde of other software, including
a variety of excellent games. A great deal of hardware is supported, and Linux
contains a complete implementation of TCP/IP networking, including SLIP,
PPP, firewalls, a full IPX implementation, and many features and some
protocols not found in any other operating system. Linux is powerful, fast, and
free, and its popularity in the world beyond the Internet is growing rapidly.
The Linux operating system itself is covered by the GNU General Public
License, the same copyright license used by software developed by the Free
Software Foundation. This license allows anyone to redistribute or modify the
software (free of charge or for a profit) as long as all modifications and
distributions are freely distributable as well. The term "free software" refers to
freedom of application, not freedom of cost.

Linux Network Administrator's Guide, 2nd Edition: Preface
Purpose and Audience for This Book
This book was written to provide a single reference for network administration
in a Linux environment. Beginners and experienced users alike should find the
information they need to cover nearly all important administration activities
required to manage a Linux network configuration. The possible range of
topics to cover is nearly limitless, so of course it has been impossible to
include everything there is to say on all subjects. We've tried to cover the most
important and common ones. We've found that beginners to Linux networking,
even those with no prior exposure to Unix-like operating systems, have found
this book good enough to help them successfully get their Linux network
configurations up and running and get them ready to learn more.
There are many books and other sources of information from which you can
learn any of the topics covered in this book (with the possible exception of
some of the truly Linux-specific features, such as the new Linux firewall
interface, which is not well documented elsewhere) in greater depth. We've
provided a bibliography for you to use when you are ready to explore more.
Sources of Information
If you are new to the world of Linux, there are a number of resources to
explore and become familiar with. Having access to the Internet is helpful, but
not essential.
Linux Documentation Project guides
The Linux Documentation Project is a group of volunteers who have
worked to produce books (guides), HOWTO documents, and manual
pages on topics ranging from installation to kernel programming. The
LDP works include:
Linux Installation and Getting Started
By Matt Welsh, et al. This book describes how to obtain, install,
and use Linux. It includes an introductory Unix tutorial and
information on systems administration, the X Window System,
and networking.
Linux System Administrators Guide
By Lars Wirzenius and Joanna Oja. This book is a guide to
general Linux system administration and covers topics such as
creating and configuring users, performing system backups,
configuration of major software packages, and installing and
upgrading software.
