Working through this section requires little more than the desire to explore, and the ability to take on board new concepts as they are introduced. Once you have traveled this far, the second, far larger, section of the Handbook is a comprehensive reference to all manner of topics of interest to FreeBSD system administrators. Some of these chapters may recommend that you do some prior reading, and this is noted in the synopsis at the beginning of each chapter.

A troubleshooting section has been added to , PPP and SLIP. , Electronic Mail, has been expanded with new information about using alternative transport agents, SMTP authentication, UUCP, fetchmail, procmail, and other advanced topics. , Network Servers, is all new with this edition. This chapter includes information about setting up the Apache HTTP Server, ftpd, and setting up a server for µsoft; &windows; clients with Samba. Some sections from , Advanced Networking, were moved here to improve the presentation. , Advanced Networking, has been expanded with new information about using &bluetooth; devices with FreeBSD, setting up wireless networks, and Asynchronous Transfer Mode (ATM) networking. A glossary has been added to provide a central location for the definitions of technical terms used throughout the book. A number of aesthetic improvements have been made to the tables and figures throughout the book. Changes from the - First Edition + First Edition (2001) The second edition was the culmination of over two years of work by the dedicated members of the FreeBSD Documentation Project. The following were the major changes in this edition: A complete Index has been added. All ASCII figures have been replaced by graphical diagrams. A standard synopsis has been added to each chapter to give a quick summary of what information the chapter contains, and what the reader is expected to know. The content has been logically reorganized into three parts: Getting Started, System Administration, and Appendices. (Installing FreeBSD) was completely rewritten with many screenshots to make it much easier for new users to grasp the text. (&unix; Basics) has been expanded to contain additional information about processes, daemons, and signals. (Installing Applications) has been expanded to contain additional information about binary package management. (The X Window System) has been completely rewritten with an emphasis on using modern desktop technologies such as KDE and GNOME on &xfree86; 4.X. (The FreeBSD Booting Process) has been expanded. (Storage) has been written from what used to be two separate chapters on Disks and Backups. We feel that the topics are easier to comprehend when presented as a single chapter. A section on RAID (both hardware and software) has also been added. (Serial Communications) has been completely reorganized and updated for FreeBSD 4.X/5.X. (PPP and SLIP) has been substantially updated. Many new sections have been added to (Advanced Networking). (Electronic Mail) has been expanded to include more information about configuring sendmail. (&linux; Compatibility) has been expanded to include information about installing &oracle; and &sap.r3;. The following new topics are covered in this second edition: Configuration and Tuning (). Multimedia () Organization of This Book This book is split into five logically distinct sections. The first section, Getting Started, covers the installation and basic usage of FreeBSD. It is expected that the reader will follow these chapters in sequence, possibly skipping chapters covering familiar topics. The second section, Common Tasks, covers some frequently used features of FreeBSD. This section, and all subsequent sections, can be read out of order. Each chapter begins with a succinct synopsis that describes what the chapter covers and what the reader is expected to already know. This is meant to allow the casual reader to skip around to find chapters of interest. The third section, System Administration, covers administration topics. The fourth section, Network Communication, covers networking and server topics. The fifth section contains appendices of reference information. , Introduction Introduces FreeBSD to a new user. It describes the history of the FreeBSD Project, its goals and development model. , Installation Walks a user through the entire installation process.

Conventions used in this book To provide a consistent and easy to read text, several conventions are followed throughout the book. Typographic Conventions Italic An italic font is used for filenames, URLs, emphasized text, and the first usage of technical terms. Monospace A monospaced font is used for error messages, commands, environment variables, names of ports, hostnames, user names, group names, device names, variables, and code fragments. Bold A bold font is used for applications, commands, and keys. User Input Keys are shown in bold to stand out from other text. Key combinations that are meant to be typed simultaneously are shown with `+' between the keys, such as: Ctrl Alt Del Meaning the user should type the Ctrl, Alt, and Del keys at the same time. Keys that are meant to be typed in sequence will be separated with commas, for example: Ctrl X , Ctrl S Would mean that the user is expected to type the Ctrl and X keys simultaneously and then to type the Ctrl and S keys simultaneously. Examples Examples starting with E:\> indicate a &ms-dos; command. Unless otherwise noted, these commands may be executed from a Command Prompt window in a modern µsoft.windows; environment. E:\> tools\fdimage floppies\kern.flp A: Examples starting with &prompt.root; indicate a command that must be invoked as the superuser in FreeBSD. You can login as root to type the command, or login as your normal account and use &man.su.1; to gain superuser privileges. &prompt.root; dd if=kern.flp of=/dev/fd0 Examples starting with &prompt.user; indicate a command that should be invoked from a normal user account. Unless otherwise noted, C-shell syntax is used for setting environment variables and other shell commands. &prompt.user; top Acknowledgments The book you are holding represents the efforts of many hundreds of people around the world. Whether they sent in fixes for typos, or submitted complete chapters, all the contributions have been useful. Several companies have supported the development of this document by paying authors to work on it full-time, paying for publication, etc. In particular, BSDi (subsequently acquired by Wind River Systems) paid members of the FreeBSD Documentation Project to work on improving this book full time leading up to the publication of the first printed edition in March 2000 (ISBN 1-57176-241-8). Wind River Systems then paid several additional authors to make a number of improvements to the print-output infrastructure and to add additional chapters to the text. This work culminated in the publication of the second printed edition in November 2001 (ISBN 1-57176-303-1). In 2003-2004, FreeBSD Mall, Inc, paid several contributors to improve the Handbook in preparation for the third printed edition.
