About the Reviewer

John C. Kennedy has worked with Unix and Linux since 1998. He has worked on Nagios as a monitoring tool for much of the past 5 years.

He has been reviewing and tech editing books in his spare time since 2001 and has about 20 open source-related books under his belt. He believes the best part of reviewing is that he learns something from every book he works on.

John was born in the U.S. and grew up in Northern Virginia. He spent some time in the U.S. Air Force and has lived in Germany and the United Kingdom. He has been married to Michele since 1994 and has two children, Denise and Kieran. He currently lives in Virginia.

I would like to thank my family, including my nephews, Aiden and Mason, and my niece, Harriet, for supporting all the silly things I do and for giving me time to work on this.

Thanks also to Nidhi Joshi whose great patience and flexibility around my very hectic schedule were VERY much appreciated. Also, my thanks go to the author, Tom Ryder. I learned a lot from the book, and it has been one of my favorite books to work on. Everyone at Packt Publishing also deserves recognition for all their titles and the hard work that goes into producing every one of them.
