commands take a long time to come back

[GREGORY JONES_3]

command prompt takes a long time to come back when they login to their workstations. their home directory is on my server. certain commands that i run, like top, showmount take a long time ( a few minutes for top) to come back.

Are you using NFS at all?

[harry d brown jr]

probably DNS issues.

post these files:

/etc/nsswitch.conf
/etc/resolv.conf

post the output of

what `which named`

Do a nslookup of a client.

Hi,

replace line
hosts: dns [TRYAGAIN=continue] files[TRYAGAIN=continue] nis

to
hosts: files [TRYAGAIN=continue] dns [TRYAGAIN=continue] nis

Also run nfsstat to see if you are getting a load of NFS errors.
