Hi all,

I made a post about this issue on the 7th of July, back then I didn't
know what was causing those error messages on my RedHat 7.3 NFS server
with kernel 2.4.18-27.7.xsmp and nfs-utils 1.0.3.

Today, a user reported a problem he has with his home directory on an
IRIX64 6.5 machine. His home used to be mounted from an SGI server,
since a couple of days, it's been moved to the Linux server. As of then,
the following problem occurs:

# cd /home/user
# pwd
/home/user
# cd work
# pwd
This command will return sometimes a), sometimes b):
a) /work
b) Cannot determine current directory
# echo $PWD
/home/user/work
echo $SHELL
/bin/tcsh (btw, it makes a difference here if I use tcsh or bash, under
bash PWD returns the correct path)

For each 'pwd' issued, where it would return b), I see the error message
"nfsd Security: //u bad export" on the console of the server. The
corresponding export entry on the server is:
/export/home/h1/u/user @user(rw,sync)

The permissions for /export/home/h1/u and /export/home/h1/u/user are
0755, the owner of /export/home/h1/u is root:root, the owner of
/export/home/h1/u/user is user:105.

Any ideas how this issue can be fixed? TIA.

Regards,

    Marc
