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.

The Debian system is a bit like a pyramid. At the base is Linux. On top of
that are all the basic tools, mostly from GNU. Next is all the application
software that you run on the computer; many of these are also from GNU.
The Debian developers act as architects and coordinators − carefully
organizing the system and fitting everything together into an integrated,
stable operating system: Debian GNU/Linux.
