“As an author, editor, and publisher, I never paid much attention to the competition–except in a few cases. This is one of those cases. The UNIX System Administration Handbook is one of the few books we ever measured ourselves against.”
–From the Foreword by Tim O’Reilly, founder of O’Reilly Media
“This book is fun and functional as a desktop reference. If you use UNIX and Linux systems, you need this book in your short-reach library. It covers a bit of the systems’ history but doesn’t bloviate. It’s just straightfoward information delivered in colorful and memorable fashion.”
–Jason A. Nunnelley
“This is a comprehensive guide to the care and feeding of UNIX and Linux systems. The authors present the facts along with seasoned advice and real-world examples. Their perspective on the variations among systems is valuable for anyone who runs a heterogeneous computing facility.”
–Pat Parseghian
The twentieth anniversary edition of the world’s best-selling UNIX system administration book has been made even better by adding coverage of the leading Linux distributions: Ubuntu, openSUSE, and RHEL.
This book approaches system administration in a practical way and is an invaluable reference for both new administrators and experienced professionals. It details best practices for every facet of system administration, including storage management, network design and administration, email, web hosting, scripting, software configuration management, performance analysis, Windows interoperability, virtualization, DNS, security, management of IT service organizations, and much more. UNIX® and Linux® System Administration Handbook, Fourth Edition, reflects the current versions of these operating systems:
Ubuntu® Linux
openSUSE® Linux
Red Hat® Enterprise Linux®
Oracle America® Solaris™ (
formerly Sun Solaris
)
HP HP-UX®
IBM AIX®
