Their steady love and encouragement has kept me on target through some trying times during the development of this book. You’re the greatest! I further dedicate this book to my late parents, Hazel and Forrest Roland, for nurturing me, teaching me right from wrong, setting a shining example of a loving partnership, and showing me the benefits of a good day’s work. I like to believe that they will be kicking up their heels together throughout eternity. From Mark Newcomb: This book is dedicated to my wife, Jacqueline, and my daughter, Isabella Rumiana. Jacqueline’s patience and under- standing while I am in the process of writing never fails to amaze me.

I want to thank Brett Bartow from Cisco Press for believing in the project and for getting the ball rolling. I would also like to thank him for turning this project over to Michelle Grandin, Cisco Press, for editorial support. Michelle helped me in many ways dur- ing this project and was always there to lend an encouraging word or a guiding hand. Dayna Isley, Cisco Press, provided developmental guidance and feedback and was way too easy on my less-than-perfect submissions, and I want to thank her for turning the work into a professional document. It has been a real pleasure to work with you three over these several months. Next, I would like to thank my co-author, Mark Newcomb, for stepping in to author half of this book when personal problems brought me to a standstill. Thank you, Mark, for your professionalism and expertise and for helping to bring this project to fruition. I would also like to thank the technical reviewers, Gert Schauwers, Scott Chen, and Thomas Scire for their comments, suggestions, and careful attention to detail. Without their help, this book would not be the valuable resource that it has become. Thank you all. From Mark Newcomb: I heartily acknowledge John Roland’s contribution to this effort and thank him for inviting me to assist in this endeavor. No text of any size is ever truly a work of just the authors. After nearly five years of writing, technical editing, and work- ing with a variety of publishers, I commend every employee of Cisco Press. Michelle Grandin, Dayna Isley, John Kane, and Brett Bartow are people at Cisco Press I have come to know and respect for their professional efforts. I also want to give special thanks to Tammi Ross. Within any organization, there is one individual that seems to be able to solve any unsolvable problem. Tammi has proven herself to be that person at Cisco Press. The technical reviewers working with Cisco Press are world class. Technical reviewers are the most valuable assets a good publisher can have. They do not receive the recognition or compensation that they so richly deserve. I thank Gert Schauwers, Scott Chen, and Thomas Scire for their efforts to make this work what it is today.
