Dedications
Brian Morgan—This book is dedicated to Beth, Emma, and Amanda. Thank you for making me complete.
Craig Dennis—This book is dedicated to my family, which is my most cherished treasure. Jacob, Sandy, Joseph, and
David thank you again and again for being as understanding as you are when Dad has to ignore you while he’s at the
keyboard. To Sharon, my wife, I thank you most of all for providing the glue that holds the family together while I’m on
the road and buried in the latest endeavor.

Acknowledgments
Brian Morgan: I’d like to thank my wife, Beth, and kids, Emma and Amanda, for putting up with me during the time
this book was being produced. It has taken me away from them more than I’d like to admit. Their patience in
temporarily setting some things aside so I could get the book done has been incredible.
I’d like to give special recognition to Bill Wagner for providing his expert technical knowledge in editing the book. As
usual, he’s not afraid to tell you when you’re wrong. He’s also been as good a friend as anyone could hope to have.
Thanks to Kale Wright for taking on additional workload to allow me to spend the necessary time writing and
researching this book.
A big “thank you” goes out to the production team for this book. John Kane, Amy Lewis, and Christopher Cleveland
have been incredibly professional and a pleasure to work with. I couldn’t have asked for a finer team.
Last, and possibly least (just kidding), I’d like to thank my co-author Craig Dennis. I approached him with this project
at the very last minute and he’s worked very hard to keep the book on time, while not sacrificing technical depth or
content.
Craig Dennis:
I want to thank Amy Lewis, John Kane, and Chris Cleveland from Cisco Press for keeping this whole thing on track.
Amy, I really, really was almost on time with some of the stuff! Thanks also to Brian Morgan my co-author who always
kept the project in focus and pushed me to keep the deadlines that we had. I should also thank all the technical and
grammatical editors that took the pieces that were delivered and made a book out of it.
Also, thanks go to my parents, as it will every time I accomplish anything. Through their guidance, encouragement, and
love I managed to get an education and develop into a reasonable human being. Thank you Pearl and Rally. I can only
hope that I can provide at least a reasonable facsimile of your guidance to my family.
And last a thank you to my wife, Sharon, who kept reminding me of the project at hand and rearranging her schedule so
I would have “quiet” times to work. As with all projects of this nature I almost feel guilty to have my name on the cover
when, without so many others this book would have never been written.
