Over the next eight years,Chris helped write (and rewrite) the thousands of pages of docu- mentation that accompanied the UNIX operating system.He stayed with the same organization,even after AT&T spun it off into UNIX System Laboratories and then to Univel,before the organization was sold (with the UNIX source code) to Novell in 1992.(Yes,this is the infamous SCO source code!) Over the following decade,Chris wrote or contributed to about a dozen UNIX books.In 1999, he made the transition to Linux with a vengeance when he wrote Red Hat Linux Bible.Since that time,the book has become a computer book bestseller and in its various editions has sold well over 240,000 copies worldwide. Between editions of Red Hat Linux Bible,Chris wrote Linux Bible,2005 Editionand co-wrote Linux Troubleshooting Biblewith Thomas Weeks.(Tom contributed two chapters to this book as well.) The originalLinux Toysand now Linux Toys IIreflect Chris’s attempts to put together open source software into fun and useful projects.The projects in this edition reflect Chris’s collabo- ration with leaders and maintainers from a handful of excellent open source initiatives. 01_579959 ffirs.qxd 9/27/05 10:33 PM Page vii Credits Executive Editor Vice President and Executive Group Carol Long Publisher Richard Swadley Acquisitions Editor Debra Williams Cauley Vice President and Executive Publisher Joseph B.Wikert Development Editor Sara Shlaer Project Coordinator Ryan Steffen Technical Editors Bharat Mediratta (Gallery) Graphics and Production Specialists Brandon Beattie,François Caen (MythTV) Carrie Foster Roberto De Leo (eMoviX) Denny Hager John Andrews,Robert Shingledecker Stephanie D.Jumper (Damn Small Linux) Barbara Moore Charles Sullivan (Heyu X10) Heather Ryan Tim Riker (BZFlag) Heiko Zuerker (Devil-Linux) Quality Control Technicians Michael Smith (Icecast) Amanda Briggs Jim McQuillan (Linux Terminal Leeann Harney Server Project) Media Development Project Supervisor Contributing Authors Laura Moss Thomas Weeks Jesse Keating Media Development Specialists Angela Denny Copy Editor Steve Kudirka Nancy Rapoport Kit Malone Travis Silvers Editorial Manager Mary Beth Wakefield Media Development Coordinator Laura Atkinson Production Manager Tim Tate Proofreading and Indexing TECHBOOKS Production Services 02_579959 ftoc.qxd 9/27/05 10:25 PM Page viii Contents at a Glance Acknowledgments. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . xvii Introduction . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . xix Part I: The Basics. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 Chapter 1:Introduction to Linux Toys II . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 Chapter 2:Finding What You Need . . . . . . . . . . . . . . . . . . . . . . . . . . . . 17 Part II: Multimedia Projects . . . . . . . . . . . . . . . . . . . . . . . . . 33 Chapter 3:Creating a Web Photo Gallery . . . . . . . . . . . . . . . . . . . . . . . . . 35 Chapter 4:Creating a Personal Video Recorder with MythTV . . . . . . . . . . . . . . . 61 Chapter 5:Making Bootable Movies with eMoviX . . . . . . . . . . . . . . . . . . . . 123 Part III: Home Projects . . . . . . . . . . . . . . . . . . . . . . . . . . . 153 Chapter 6:Customizing a Live Linux Pen Drive . . . . . . . . . . . . . . . . . . . . . 155 Chapter 7:Automating Home Lights and Gadgets with X10 . . . . . . . . . . . . . . . 185 Chapter 8:Setting Up a Game Server with BZFlag . . . . . . . . . . . . . . . . . . . . 209 Chapter 9:Building a Dedicated SOHO Firewall . . . . . . . . . . . . . . . . . . . . . 237 Part IV: Small Business Projects . . . . . . . . . . . . . . . . . . . . . . 265 Chapter 10:Running an Internet Radio Station with Icecast . . . . . . . . . . . . . . . 267 Chapter 11:Building a Thin Client Server with LTSP . . . . . . . . . . . . . . . . . . 289 Part V: Appendixes . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 319 Appendix A:Using the Linux Toys II CD . . . . . . . . . . . . . . . . . . . . . . . . . 321 Appendix B:ABCs of Using Linux . . . . . . . . . . . . . . . . . . . . . . . . . . . . 329 Appendix C:Installing Linux . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 355 Index . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 373
