hostname

resolution

Do the hostname resolution servers

respond with accurate information?

• Even when the repository servers are responding quickly,

if they don’t contain the requested information, then NFS

behavior and performance can be severely impacted

• Do your repository servers contain information about

every NFS client and server system in your

environment?

• Is the hostname-to-address information up-to-date?

• Verify with nslookup(1) and nsquery(1)

Even when the hostname repositories are responding very quickly to resolution

requests, if they don’t have the requested data or if they return inaccurate data, the

results can be devastating to NFS behavior and performance. Verify that your

repository servers contain up-to-date information for all the NFS client and server

systems in your environment.

The nslookup(1) and nsquery(1) commands can be used to query the hostname

resolution servers, allowing you to verify the accuracy of the information returned.
