NFS error on linux

[Jerry P Antony_2]

Hi
NFS server=hpux 10.20
NFS client red hat workstation 3

Problem
I am getting the following error while listing the files on nfs mounting
ls: reading directory .: Unknown error 525
total 0
If I mount the same directory on hp unix 11.0 machine, then it is working fine.
Thanx in advance for the help
Jerry

are you able to explicitly copy files from that directory.

just check df and see whether the nfs mount is listed.

one possible reason incompatibility between NFS server and client, just check for any advisory on this.

The 10.20 box is probably running and old 2.x version of NFS. Thats too old for the Linux client to handle. Guess Linux distribution didn't get the downard compatability so right.

You should probably upgrade the NFS server on the 10.20 box.

NFS 2 on the server? Ok. Have you tried forcing the Linux box into using only NFS v2 protocol, instead of letting it try to auto-detect?

Actually, by default it should be using NFS2, but you can force it by using:

mount -onfsvers=2 hpux:/path/to/mount /local/path

See 'man nfs' on the Linux box to see the mount options available.
