Acknowledgments

The authors would like to thank Ken Stone, Jerry McCollom, Peter Jeffe, Hal Stern, Christopher Durham, Bill Wisner, Dave Curry, Jeff Okamoto, Brad Knowles, K. Robert Elz, and Paul Vixie for their invaluable contributions to this book. We'd also like to thank our reviewers, Eric Pearce, Jack Repenning, Andrew Cherenson, Dan Trinkle, Bill LeFebvre, and John Sechrest for their criticism and suggestions. Without their help, this book would not be what it is (it'd be much shorter!).

For the second edition, the authors add their thanks to their sterling review team: Dave Barr, Nigel Campbell, Bill LeFebvre, Mike Milligan, and Dan Trinkle.

For the third edition, the authors salute their technical review Dream Team: Bob Halley, Barry Margolin, and Paul Vixie.

For the fourth edition, the authors owe a debt of gratitude to Kevin Dunlap, Edward Lewis, and Brian Wellington, their crack review squad.

Cricket would particularly like to thank his former manager, Rick Nordensten, the very model of a modern HP manager, on whose watch the first version of this book was written; his neighbors, who bore his occasional crabbiness for many months; and of course his wife, Paige, for her unflagging support and for putting up with his tap-tap-tapping during her nap-nap-napping. For the second edition, Cricket would like to add a thank you to his former managers, Regina Kershner and Paul Klouda, for their support of Cricket's work with the Internet. For the third edition, Cricket acknowledges a debt of gratitude to his partner, Matt Larson, for his co-development of the Acme Razor. For the fourth edition, Cricket thanks his loyal, furry fans, Dakota and Annie, for kisses and companionship, and wonderful Walter B., for popping his head into the office and checking on Dad now and again. Paul would like to thank his wife, Katherine, for her patience, for many review sessions, and for proving that she could make a quilt in her spare time more quickly than her spouse could write his half of a book.

We would also like to thank the folks at O'Reilly & Associates for their hard work and patience. Credit is especially due our editors, Mike Loukides (first through third editions) and Debra Cameron (fourth edition), as well as countless others who worked on the various editions: Nancy Kotary, Ellie Fountain Maden, Robert Romano, Steven Abrams, Kismet McDonough-Chan, Seth Maislin, Ellie Cutler, Mike Sierra, Lenny Muellner, Chris Reilley, Emily Quill, Anne-Marie Vaduva, and Brenda Miller. Thanks besides to Jerry Peek for all sorts of miscellaneous help and to Tim O'Reilly for inspiring us to put it all in print.

And thanks, Edie, for the cricket on the cover!
