Learn to use it today and you’ll be ready for upcoming enterprise Linux systems when they arrive. Install, configure, and use Fedora as anything from a desktop to an Internet server.

  • 2. Ten cool things to do with Fedora 11 Linux Just because Fedora is a serious operating system doesn't mean it can't be fun too. Here is a list of ten fun and useful things to do with Fedora. 1. Set Up a Personal Online Desktop: Use the GNOME Online Desktop to connect your desktop to your friends, multimedia content, and online applications from Google, Facebook, Yahoo!, and others. Click right on the desktop to immediately get you all your favorite content. (See Chapter 3.) 2. Launch Fedora 11 live on your PC: Insert the live CD that comes with this book, reboot, and start using Fedora from nearly any PC. Fedora won’t touch the contents of your computer unless you tell it to. If you like Fedora, select the Install button to install Fedora to your hard disk. (See Chapter 3.) 3. Play Commercial Audio/Video: Licensing restrictions keep many popular codecs from inclusion with Fedora. Using third-party repositories with Fedora, you grab the codecs you need to play Windows Media (Audio, Video and MMS), MP3 audio, MPEG-2 and MPEG-4 video decoding, and others. (See Chapter 8.) 4. Manage music collections: Launch Rhythmbox to gather, organize, and play music from your hard disk, CDs, or network file systems. You can even select from thousands of free songs from Magnatune and Jamendo online music services. (See Chapter 8.) 5. Publish your ideas: Choose from dozens of publishing tools to create documents (OpenOffice.org Writer), presentations (OpenOffice.org Impress) hard-copy page layouts (Scribus), and vector graphics (Inkscape). Then publish your work on paper or the Web. (See Chapter 6.) 6. Share an Internet connection: Fedora can be set up as a router and a firewall. With a home or small office LAN set-up, you can use Fedora to share an Internet connection among multiple Linux, Windows, or Mac systems. Then set up a firewall in Fedora to protect your LAN from intruders. (See Chapters 14, 15, and 16.) 7. Play free games: As always, Fedora includes dozens of simple card games and board games. The Fedora repository includes a ton of games, including fun first-person shooter games such as Doom, strategy games such as fantasy game Wesnoth, and online battle games such as BZFlag. (See Chapter 7.) 8. Run Windows applications: By adding the wine software packages, you can run many Windows applications right from a Fedora desktop. (See Chapter 5.) 9. Create an Internet server: Learn to configure a Web server (Chapter 21), FTP server (Chapter 20) and a mail server (Chapter 19). Then use that knowledge to create a public Internet server (Chapter 25). Your server can run from your home Internet connection. 10. Share over the Internet: Share your personal videos, software, or other content with friends over the Internet, using Bittorrent swarming network transfer software. While you’re at it, instant message your thoughts using Pidgin, video-conference your looks with Ekiga, and e-mail your party invitations via Evolution. (See Chapter 7.)

  • 6. As always, I dedicate this book to my wife, Sheree. This book would never have happened without her love and support. –ChristopherNegus To Katya and Nalana –Eric Foster-Johnson
  • 7. About the Authors Christopher Negus has been working with UNIX systems, the Internet, and (most recently) Linux systems for more than two decades. During that time, Chris worked at AT&T Bell Laboratories, UNIX System Laboratories, and Novell, helping to develop the UNIX operating system. Features from many of the UNIX projects Chris worked on at AT&T have found their way into Red Hat Enterprise Linux, Fedora, and other Linux systems. Chris is the author of all editions of what started out as Red Hat Linux Bible, which because of the name changes of Red Hat’s Linux projects has evolved into the book you are holding. Most recently, Chris co-authored multiple books in the Linux Toolbox series: Fedora Linux Toolbox, Ubuntu Linux Toolbox, Mac OS X UNIX Toolbox, SUSE Linux Toolbox, and BSD UNIX Toolbox (Wiley Publishing). Besides that, Chris authored Linux Bible 2009 Edition and co-wrote CentOS Bible, Linux Troubleshooting Bible and Linux Toys II for Wiley Publishing. Chris also authored Live Linux CDs and co-authored the Official Damn Small Linux Book, as part of the Negus Software Solutions Series. Today, Chris works as a Linux instructor for Red Hat, Inc. and has achieved certification as a Red Hat Certified Engineer (RHCE) and Red Hat Certified Examiner (RHCX). At home, Chris enjoys spending time with his wife, Sheree, and his boys, Caleb and Seth. His hobbies include soccer, singing, and exercising with Sheree. Eric Foster-Johnson is a veteran programmer who works daily with Linux, Unix, and Windows and other operating systems. By day, he writes enterprise Java software for ObjectPartners, a Minnesota consulting firm. He has authored and co-authored a number of Linux and Unix titles including Red Hat RPM Guide, Teach Yourself Linux, Teach Yourself Unix, and Perl Modules.

  • 9. Acknowledgments A special acknowledgment goes to the people at Red Hat, Inc. and members of the Fedora Project. In particular, Paul Frields (Fedora Project leader), Max Spevack (outgoing Fedora Project leader) and Greg DeKoenigsberg (Fedora Community leader) deserve praise for their leadership in producing a consistently high-quality Linux distribution. Special thanks to Pete Hnath (my new boss at Red Hat) for allowing me to complete my work on this book after hiring me to be an instructor at Red Hat. Eric Foster-Johnson continues to be a major contributor to the new content in this book. I feel very fortunate to have someone as skillful as Eric as partner with me on this book that I have put so much effort into in the past decade. At Wiley, I’d like to thank Jenny Watson, Ashley Zurcher, and Laura Moss-Hollister for helping work out issues related to the publicity, media, and covers for this book. Thanks to Sara Shlaer for her continued great editing and production work on this book, and for keeping me on schedule so we could bring this book to you on time. Thanks to Daniel Scribner for shepherding the book through the final stages of production. Rob Shimonski provided a thorough technical editing pass. Thanks also to Margot Maley Hutchison and the others at Waterside Productions for bringing me this project. Thanks, as always, to my dear family for helping me through this project. Finally, a special thanks goes to those of you who bought this and earlier editions of Red Hat Linux Bible. Go out and become a force for Linux in your work, home, and community. If you feel like expanding your Linux horizons, try some of these other books I’ve written: • Linux Bible 2009 Edition — Contains 18 different bootable and installable Linux distributions on DVD and CD, along with descriptions characterizing those and other popular and interesting Linux distributions. (Look for the Linux Bible 2010 Edition coming in November 2009.) • Fedora Linux Toolbox with François Caen — Includes 1000+ command lines to help Fedora, RHEL, and CentOS power users get the most out of Linux. To try other similar distributions, check out Ubuntu Linux Toolbox, SUSE Linux Toolbox and BSD UNIX Toolbox by the same authors. • Linux Troubleshooting Bible with Thomas Weeks — Goes beyond this book to help you safely deploy and troubleshoot Linux systems. • Linux Toys II — If you’re looking for something fun to do with Linux, this book contains nine fun projects you can build with a PC and open source software. -- Chris Negus
