hostname
resolution
Are the hostname resolution servers
responding quickly to requests?
• Any latency involved in retrieving hostname or IP address
information can negatively impact NFS performance
• Verify that lookup requests are resolved quickly
Ø nslookup(1)
– Supports DNS, NIS, /etc/hosts
– Doesn’t support NIS+
Ø nsquery(1)
– Supports DNS, NIS, NIS+, /etc/hosts
HP-UX supports many different directory service back-ends for hostname resolution
data – DNS, NIS, NIS+, and /etc/hosts. Each of these repositories has
different amounts of overhead associated with retrieving hostname data from them.
Any latency involved in retrieving this information can negatively impact NFS
performance.
The nslookup(1) and nsquery(1) commands can be used to test the performance of
your hostname resolution servers.
