For over a decade, The Practice of System and Network Administration has been the industry's definitive guide to managing computer systems and networks. Now, its award-winning authors have thoroughly updated this classic for the latest real-world challenges.

Chapter summaries, future speculations sections, and further reading sections have been added, and all end-of-chapter questions have been updated. The authors' lively, witty style and their use of anecdotes and case studies drawn from personal experience all make this book as entertaining as it is useful.
