Self Service Linux
"This welcome addition to the Linux bookshelf provides real insight into the black-art of debugging. All too often debugging books concentrate solely on the tools but this book avoids that pitfall by concentrating on examples. The authors dissect and discuss each example in detail; in so doing they give invaluable insight into the Linux environment."
??Richard
J Moore, IBM Advanced Linux Response Team-Linux Technology Centre
"A plethora of Linux books exist but this guide offers a definitive overview of practical hints and tips for Linux users. Written by experts in the field, it will be extremely useful for system administrators and Linux enthusiasts."
??Markus Rex, VP and General Manager, SUSE LINUX

The indispensable start-to-finish troubleshooting guide for every Linux professional
Now, there's a systematic, practical guide to Linux troubleshooting for every power user, administrator, and developer. In Self-Service Linux, two of IBM's leading Linux experts introduce a four-step methodology for identifying and resolving every type of Linux-related system or application problem: errors, crashes, hangs, performance slowdowns, unexpected behavior, and unexpected outputs. You'll learn exactly how to use Linux's key troubleshooting tools to solve problems on your own??and how to make effective use of the Linux community's knowledge.
If you use Linux professionally, this book can dramatically increase your efficiency, productivity, and marketability. If you're involved with deploying or managing Linux in the enterprise, it can help you significantly reduce operation costs, enhance availability, and improve ROI.
