1. Colophon

Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects. The figure on the cover of Network Security Tools is a trapeze artist, the most romantic of circus performers. The allure of the trapeze performance, with its breathtaking aerial acrobatics and seemingly effortless flight, belies grave danger: the artist performs without a security net, so the slightest of mistakes can endanger a performer's life. Jamie Peppard was the production editor and proofreader, and Audrey Doyle was the copyeditor for Network Security Tools. Claire Cloutier and Matt Hutchinson provided quality control. Lydia Onofrei provided production assistance. Ellen Troutman Zaig wrote the index.

Emma Colby designed the cover of this book, based on a series design by Edie Freedman. The cover image is a 19th-century engraving from Dover's Old Time Circus Cuts. Karen Montgomery produced the cover layout with Adobe InDesign CS using Adobe's ITC Garamond font.

David Futato designed the interior layout. This book was converted by Keith Fahlgren to FrameMaker 5.5.6 with a format conversion tool created by Erik Ray, Jason McIntosh, Neil Walls, and Mike Sierra that uses Perl and XML technologies. The text font is Linotype Birka; the heading font is Adobe Myriad Condensed; and the code font is LucasFont's TheSans Mono Condensed. The illustrations that appear in the book were produced by Robert Romano, Jessamyn Read, and Lesley Borash using Macromedia FreeHand MX and Adobe Photoshop CS. The tip and warning icons were drawn by Christopher Bing. This colophon was written by Jamie Peppard.
