"Where has this book been all my professional life? It is about time someone wrote this book. The author covers many basic, practical issues that other authors omit in a format that makes for a great troubleshooting reference and for casual perusing. There are a lot of books available that give a broad overview of system and network administration, and there are a lot of detailed books on each specific topic covered in this book, but I don't know of any other place where I can get so much useful, practical information on such a wide range of topics in such a concise and readable form. I will highly recommend it to my friends and colleagues who are trying to manage their own systems. I am anxious to show it to our instructors who teach data communications and networks as a possible text or lab manual."—Ron McCarty, instructor and program chair, Computer Science, Penn State Erie"This book takes a very unique approach and is very flexible. It offers a great deal to the home user, students, small businesses—all the way to any Linux sys admin that needs a handy reference. I found it very refreshing in terms of style, stated goals, presentation, ease of use, direction, and the "present and future" value of the content. In other words the author is very current and knowledgeable. I would recommend this book to every level from programmer to manager."—Joe Brazeal, Information Technician III, Southwest Power Pool"This book is an excellent resource for new Linux administrators. I was impressed with the comprehensive set of 35 topic chapters, making this book a very useful reference. I know of no other work like this."—George Vish II, Linux curriculum program manager and senior education consultant, Hewlett-Packard Education"I would recommend this book to novice Linux users and administrators. It covers a lot of topics, and makes it easy for readers to follow along."—Bret
