This complete guide to setting up and running a TCP/IP network is essential for network administrators, and invaluable for users of home systems that access the Internet. The book starts with the fundamentals -- what protocols do and how they work, how addresses and routing are used to move data through the network, how to set up your network connection -- and then covers, in detail, everything you need to know to exchange information via the Internet.

Included are discussions on advanced routing protocols (RIPv2, OSPF, and BGP) and the gated software package that implements them, a tutorial on configuring important network services -- including DNS, Apache, sendmail, Samba, PPP, and DHCP -- as well as expanded chapters on troubleshooting and security. TCP/IP Network Administration is also a command and syntax reference for important packages such as gated, pppd, named, dhcpd, and sendmail.

With coverage that includes Linux, Solaris, BSD, and System V TCP/IP implementations, the third edition contains:

Overview of TCP/IP
Delivering the data
Network services
Getting startedM
Basic configuration
Configuring the interface
Configuring routing
Configuring DNS
Configuring network servers
Configuring sendmail
Configuring Apache
Network security
Troubleshooting
Appendices include dip, ppd, and chat reference, a gated reference, a dhcpd reference, and a sendmail reference

This new edition includes ways of configuring Samba to provide file and print sharing on networks that integrate Unix and Windows, and a new chapter is dedicated to the important task of configuring the Apache web server. Coverage of network security now includes details on OpenSSH, stunnel, gpg, iptables, and the access control mechanism in xinetd. Plus, the book offers updated information about DNS, including details on BIND 8 and BIND 9, the role of classless IP addressing and network prefixes, and the changing role of registrars.

Without a doubt, TCP/IP Network Administration, 3rd Edition is a must-have for all network administrators and anyone who deals with a network that transmits data over the Internet.

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 animal on the cover of TCP/IP Network Administration is a land crab. Land crabs are found in tropical America, West Africa, and the Indo-Pacific region where they can be found living in burrows in fields, swamps, and mangrove thickets. They occasionally are found as far as five miles inland, returning to the sea to spawn. Land crabs are a subgroup of over 4,500 species of crabs. Classified with shrimp, lobster, and crayfish, crabs differ from these in their tail structure. Unlike the rest of their order, crabs' tails are curled under their thorax. In addition, their carapaces tend to be unusually broad. Though land crabs in the United States commonly grow to weigh no more than 18 ounces and measure 4 or 5 inches across, crabs in general range in size from less than a centimeter across to the largest, the Japanese spider crab, whose claws can span 12 feet. Emily Quill was the production editor and copyeditor for TCP/IP Network Administration, Third Edition. Jeffrey Holcomb and Jane Ellin provided quality control. Derek Di Matteo and Sue Willing provided production assistance. Tom Dinse wrote the index.

Edie Freedman designed the cover of this book, using a 19th-century engraving from the Dover Pictorial Archive. Emma Colby produced the cover layout with QuarkXPress 4.1 using Adobe's ITC Garamond font.

Melanie Wang designed the interior layout, based on a series design by David Futato. Neil Walls converted the files from Microsoft Word to FrameMaker 5.5.6 using tools created by Mike Sierra. 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 and Jessamyn Read using Macromedia FreeHand 9 and Adobe Photoshop 6. The tip and warning icons were drawn by Christopher Bing.
