Reading a book on UNIX networking is one thing; putting it to use at a real site is another. UNIX Networks is designed for system administrators or UNIX power users looking for solutions to the most common UNIX networking problems. Using a step-by-step approach, this guide covers such topics as network topology, network design and implementation, ethernet-TCP/IP protocols, routers, file servers including NFS, print servers, and network diagnostics. Special chapters are included on how to administer the X Window System on a network, the Domain Name system (DNS), sendmail, and actual administration scenarios. Commercial UNIX sites almost always grow faster than expected. The authors explain what to do when subnetting and routing become necessary, defining how bridges and routers work, how they are programmed, and the differences between them. The information in this book is based on over a decade of experience in UNIX system administration.
