Linux Administration Handbook 2nd Edition


“‘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

BOOK Description

“As this book shows, Linux systems are just as functional, secure, and reliable as their proprietary counterparts. Thanks to the ongoing efforts of thousands of Linux developers, Linux is more ready than ever for deployment at the frontlines of the real world. The authors of this book know that terrain well, and I am happy to leave you in their most capable hands.”
—Linus Torvalds

“The most successful sysadmin book of all time—because it works!”
—Rik Farrow, editor of ;login:

“This book clearly explains current technology with the perspective of decades of experience in large-scale system administration. Unique and highly recommended.”
—Jonathan Corbet, cofounder,

“Nemeth et al. is the overall winner for Linux administration: it’s intelligent, full of insights, and looks at the implementation of concepts.”
—Peter Salus, editorial director,

Since 2001, Linux Administration Handbook has been the definitive resource for every Linux® system administrator who must efficiently solve technical problems and maximize the reliability and performance of a production environment. Now, the authors have systematically updated this classic guide to address today’s most important Linux distributions and most powerful new administrative tools.

The authors spell out detailed best practices for every facet of system administration, including storage management, network design and administration, web hosting, software configuration management, performance analysis, Windows interoperability, and much more. Sysadmins will especially appreciate the thorough and up-to-date discussions of such difficult topics such as DNS, LDAP, security, and the management of IT service organizations.

Linux® Administration Handbook, Second Edition, reflects the current versions of these leading distributions:

  • Red Hat® Enterprise Linux®
  • FedoraTM Core
  • SUSE® Linux Enterprise
  • Debian® GNU/Linux
  • Ubuntu® Linux

Sharing their war stories and hard-won insights, the authors capture the behavior of Linux systems in the real world, not just in ideal environments. They explain complex tasks in detail and illustrate these tasks with examples drawn from their extensive hands-on experience.
