Configuring and Administering NFS Services
Prerequisites
Chapter 2 43
Prerequisites
Before you configure your system as an NFS server or as an NFS client,
perform the following prerequisite checks:
• Verify network connectivity
• Verify user IDs and group IDs setup
• Verify group restrictions
Verifying Network Connectivity
Before you configure NFS, you must have already installed and
configured the network hardware and software on all the systems that
use NFS. For information on installing and configuring the network
hardware and software, see the following documents:
• HP-UX LAN Administrator’s Guide (B2355-90796)
• Ethernet Configuration and Verification (5991-5954)
To check the network connections between the server and clients, use the
/usr/sbin/ping command to verify network connectivity between your
proposed NFS client and server systems.
Verifying User IDs and Group IDs Setup
When users request NFS access to remote files, their user IDs and group
IDs are used to check file ownership and permissions.
NOTE NFSv4 uses string identifiers that map to user IDs and group IDs in the
standard integer format. For more information on string identifiers
supported on NFSv4, see “New Features in NFS” on page 21.
Consider the following points when you set user IDs and group IDs:
• Each user must have the same user ID on all systems where that
user has an account.
