Two issues I have come across.

One is that all actions need root permissions.

The second is that you need top pay attention to the exports file

This is a sample that works for me on my local network
/etc/exports
/var/www  *(rw,sync,no_root_squash,no_subtree_check)

remember to ruin as root exportfs after changes.


On a wide area network where I am accessing a virtual private server via
NAT, I needed to modify things a little as the  router used an
'insecure' - high number port to access the server.

/var/xxx.co.uk  *(rw,sync,no_root_squash,no_subtree_check,insecure)

I am not sure that either of those is your problem, however.

Another problem may be incompatible versions. You can force a given
version of nfs using extra fields in fstab or mount. Check to see if
nfsvers=3 works for example or nfsvers=2 or nfsvers=4. If using mount use
-o nfsvers=4
etc.


I know that my older nfs clinet here doesn't default to version 4, but
my newer server does!

Finally, is there anything wrong permissions wise with where you are
trying to mount?

You can check what is being exported on the server from the client using
showmount --exports 

This may not work on incompatible versions


That's all I can think of right now.
