Description:

A modern computer system that's not part of a network is even more of an anomaly today than it was when we published the first edition of this book in 1991. But however widespread networks have become, managing a network and getting it to perform well can still be a problem. "Managing NFS and NIS, in a new edition based on Solaris 8, is a guide to two tools that are absolutely essential to distributed computing environments: the Network Filesystem (NFS) and the Network Information System (formerly called the "yellow pages" or YP). The Network Filesystem, developed by Sun Microsystems, is fundamental to most Unix networks. It lets systems ranging from PCs and Unix workstations to large…

Mike Eisler graduated from the University of Central Florida with a master's degree in computer science in 1985. His first exposure to NFS and NIS came while working for Lachman Associates, Inc., where he was responsible for porting NFS and NIS to System V platforms. He later joined Sun Microsystems, Inc., responsible for projects such as NFS server performance, NFS/TCP, WebNFS, NFS secured with Kerberos V5, NFS Version 4, and JavaCard security. Mike has authored or coauthored several Request For Comments documents for the Internet Engineering Task Force, relating to NFS and security. He is currently a Technical Director at Network Appliance, Inc.

Ricardo Labiaga is a staff engineer at Sun Microsystems, Inc., where he concentrates on networking and wireless technologies. Ricardo spent 8 years in the Solaris NFS group at Sun, where he worked on a variety of development projects with a primary focus on automounting and the NFS server. Ricardo is responsible for implementing significant functionality and performance enhancements to the automounter, as well as leading the NFS Server Logging design team. He holds a master of science degree in computer engineering from The University of Texas at El Paso.
