The first edition of this book became known for its thorough and lucid coverage of some of the toughest topics in system administration, including DNS, sendmail, and security. The new edition will focus on many open source tools that have gained acceptance since 1/e was published, including Nagios for network monitoring. Most titles on Linux administration focus on the configuration of a single box. Linux Administration Handbook (LAH) was the first title in this area to focus on the administration of a Linux system in a production environment. LAH examines how Linux systems behave in real-world ecosystems, not how they might behave in ideal environments. The Second Edition incorporates the changes in Linux systems in the past 54 months, which include current versions of RedHat, SuSE and Debian systems, new topics like Logical Volume Manager, X11 basic administration, and Nagios. Chapters on system admin policy, bind, sendmail, and security have been updated.Major revision of must-have guide for Linux administrators working in production environments.° Full section on LVM, Logical Voume Manager, subsystem for on-line disk storage management° X11 basic administration and° Significantly expanded coverage of patch management° Nagios, open source host and network monitoring program"'Linux Administration Handbook, 2nd Edition deserves a place of honor on the shelf of every practicing Linux admin and anyone else who wants to learn. I predict though, that it won't spend many hours on the shelf. It is better used by your side at the keyboard and you learn from its pages."-James Pyles, Reviewer, The Linux Tutorial
