Hello,

Thanks for the reply and sorry for various omissions. I believe the 
server is NFSv4. The (Debian) client I'm not so sure about as it appears 
to be able to talk all three versions. By the way, there are no firewalls 
active between these two machines.

After checking your supplied URL and digging a little deeper, I found 
with which I'm happy although it may not be to everyone's taste.

First of all, the /etc/exports line as it stands now.

/home/pete/     doggett.nrth.lab(rw)

I've removed 'no_root_squash' and indeed root on the client cannot access 
the mounted NFS share, neither can any other user which was as expected 
so that'll do for now.

Any other user that is, apart from myself. I found this very useful page 
and within was the solution which I found most suitable.

nfs.htm#_Mounting_an_NFS_Share_on_a_Client


The solution (for me) was to change the UID and GID of my user account on 
the Debian box to match that of the server's record of the same username. 
So 'pete' on both boxes is now '500' in /etc/passwd and /etc/group. A 
quick chown -R pete:pete /home/pete and a (reflex) reboot and the 
following mount command worked as before but this time I was able to 
access the share.

mount -t nfs4 tooms.nrth.lab:/home/pete /home/pete/serverdocs

Thanks again for the reply and for the motivation.

Regards,

Pete.
