As unlikely as it may seem, we still had no idea how much time and effort the second edition would take when we started working on it; what we expected to be a relatively simple effort has turned into a marathon. Even the smallest revision requires many hands, and a fully new edition requires what seems like a cast of thousands.
Thanks to those who reviewed the second edition and made helpful comments: Steve Beaty, David LeBlanc, Phil Cox, Eric Pearce, Chuck Phillips, Greg Rose, and Wietse Venema—and to Bruce Schneier and Diana Smetters who read Appendix C on a four-hour turnaround! Thanks to the entire editorial and production team at O'Reilly, especially project manager Madeleine Newell and production editor Nancy Crumpton.
Elizabeth says: My thanks to my friends, family, and colleagues for their patience and aid; my monomaniacal interest in network protocols coupled with emotional instability and intermittent overwork have required more than a reasonable and customary amount of tolerance. I am particularly indebted to Arnold Zwicky, Diana Smetters, Jeanne Dusseault, and Brent Chapman. Special thanks are due to my second father, Jacques Transue, who required me to take slow and calm breaks from writing. Thanks to Debby Russell and Sue Miller at O'Reilly for their deft, patient, and calm job of editing; and to Simon, who expected a simple writing project, got his life disrupted for more than a year and a half, and kept working anyway, even though we insisted on spelling everything in American instead of proper English. And thanks to the many O'Reilly people who helped to produce this book.
Simon says: I would like to thank my colleagues, my friends, and my family for their understanding and support during this project. Particular thanks go to Beryl Cooper, Mel Pleasant, Landon Curt Noll, Greg Bossert, James R. Martin II, Alesia Bischoff, and Cherry Mill for their encouragement and patience. A special mention goes to my ice hockey teammates—thanks for such an active alternative to writing. Enormous thanks to Elizabeth for asking me to coauthor and for coaching me through the process. Finally, thanks to Debby, Sue, and the staff of O'Reilly for putting this book into the hands of our readers.
