Yes cdr1 NFS server is running.

[harry d brown jr]

From umhcdr can you ping cdr1.umm.edu? Also from umhcdr can you do an nslookup for cdr1.umm.edu? And from cdr1.umm.edu can you do an nslookup for umhcdr??

On cdr1.umm.edu what does your /etc/exports file look like?

Yes, both machine can ping each other, and can do nolookup each other.
exports:
/export -anon=65534,access=umhcdr:oracle

[harry d brown jr]

Kuang,

Does cdr1.umm.edu have a UID of 65534?

Also in the hostlist, what does "oracle" signify: "access=umhcdr:oracle" ??

cdr1 does not have UID 65534

oracle do not need to be there.

The NFS used be work well, these two weeks, it's become very slow to copy file from local (umhcdr) to NFS mount directory.
