ULTRIX-32 Guide to the Network File System

This document is the "ULTRIX-32 Guide to the Network File System (NFS)", intended for system and network managers on ULTRIX operating systems. Published by Digital Equipment Corporation for ULTRIX-32 Operating System, Version 3.0, it provides comprehensive information on implementing, managing, and troubleshooting NFS.

The guide covers:

• Introduction to NFS: Explaining client-server relationships, the NFS service, key daemons (portmap, mountd, biod, nfsd), and the NFS locking service.
• Setting Up NFS: Detailed instructions for both automatic configuration via nfssetup and manual setup by editing crucial files like /etc/exports (for exporting file systems) and /etc/fstab (for client mounts).
• Managing NFS: Topics include mounting remote file systems, programming with the NFS locking service, recovering NFS locks, and addressing system security aspects (e.g., superuser access, port monitoring, and restricting exports). It also discusses potential system differences like clock skew.
• Troubleshooting: A dedicated section on common NFS malfunctions, providing remedies for network/server failures, remote mount errors, client program blocking, system hangs, slow file access, and interpreting NFS console error messages.
