Summary: Good Bang for your buck
Comment: This series is a great place to start learning the some of the most useful aspects of linux in a networked environment. The examples used in the book are very well laid out and documented. My only gripe is that the subject is a little dated but overall it is still a very good book.
This is a great reference book, power users will find this book helpful as well as the second edition. One can expect to learn some of the fundamentals of linux with this book; backup, network shares, hostkeys, centralizing, and some other nifty one off mini-programs. This won't replace a lot of hard work, but it will make you think how you can work smarter.

Summary: Good first step into being a Linux Sysadmin
Comment: When you're ready to take your Linux expertise from the "desktop" level to the "server" level, this is the right place to start. It avoids trying to teach you everything and instead sprinkles your brain with possibilities. There are some interesting ways to do things and as your skill grows you'll find more uses for what's in the book.
The only downers were the Version Control chapter--everyone has a preference and most methods have decent tutorials, and the use of perl in scripts. If you're good in perl then you can expand the scripts, otherwise it'd be cleaner and better to use Bash for the script examples.

Summary: Great book for intermediate users
Comment: If you are an aspiring Linux hacker/guru, you need this book. Sure, a lot of this information can be found online, but this book is so cheap there's no reason not to have a copy.
I read this book after I'd tinkered a bit with Linux and taken a few online "system administration" courses in it. I knew the basics of operating Linux, but had no clue where to go next. If you've been through the "textbook" courses and want to take your next step, this is a good book to help you get your hands dirty setting up some useful stuff.

Summary: Great Hacks, Skimpy on Facts
Comment: This O'Reilly title really impressed me with useful tricks, such as running a shell command on multiple hosts or using a Makefile to maintain sendmail map files; however, while it gives you the short cut to do something, it doesn't always explain the syntax of the commands used.
I wanted to use the Makefile to maintain files in my Postfix configuration, but the author didn't explain the entries in the sendmail Makefile enough to customize it to my own needs. It wouldn't taken little time and made the tip more useful to budding sysadmins.
Still, the book is well worth the purchase price, and one can always glean custom techniques off the net.
