A must have for any Linux sysadmin I am giving it 4 instead of 5 only for being a little rpm-ized, (as I am a fan of Debian). Even if you know almost everything, this book can help as a sumarized how-to of many things you'll need to setup at a given time.
A valuable reference work giving understanding of Linux networking issues Some books are glanced at but then remain on the bookshelf: Not so with this book whcih will be a constant source of valuable reference material providing not only an understanding of how the software underlying basic networking connections works, but also how to set up and troubleshoot file servers, mail servers and web servers. In addition security matters are included, and even excellent tips on VPNs and wireless networking troubleshooting. Of course all of these topics are constantly at the cutting edge, and will move forward constantly after publication of the book, and yet much of the underlying understanding presented in the book remains valid which is what makes this dipping-into source of reference material so useful. This book is ideal for the Linux user who yearns for a deeper understanding of the above topics so that a start can be made into setting up and problem-solving the various networking issues that make a PC into a real workhorse.The best Linux book I've read If you get one book on Linux, this is the one. This book is perfect for anyone with IT experience in another area (MS, Cisco, Netware, etc) that needs the details and exact examples to get the job done in Linux. The book is written in clear, concise language with examples that get your system running immediately. Unlike most Linux books, this book gets the job done without assuming the reader wants to rewrite source code, or endless pointing back to man pages or web sites. In one day I had installed and configured a system that ran a web site, a mail server, and was monitoring all my Cisco devices. Kudos Mr. Harrison
