I have been programming applications under Linux off and on for ten years. But I am getting serious in using Linux for my business as a file and remmote testing server system. I admire Linux for its long term operation reliability and it's versitility, not to speak of its open source documentation. So, I needed to see what would be needed both in terms of administration operations and in terms of best practices. I'm still wondering how to get a drive set partitioned for multi-booting, but this book answers most of the administration questions and gives me practice tests for certification.

After reading( and skimming ) this book in one day, I have the knowledge to install the OS, patch the kernel, set up several types of servers, and apply system security and networking services.
This is exactly the kind of support that I'm seeking for my knowledge base, and I suspect that you are too. I wish to commend the author for being so comprehensive in his coverage and letting us know how to prepare to run our own systems so well. The Linux environment has been something of a closed environment to those who can't afford an expensive seminar or training school until recently. This book helps to open up the Linux world to the rest of us. I hope you get as much out of this book as I did. And, by the way, if you are only concerned in passing the certification test, it is a very good training source for that as well.
