Ive tried all possible permutations of this. I had tried the correct one as
well

Missed most of the thread, but if it hasn't be covered already...

When I've seen this, it is either;

* /etc/exports not setup correctly.
* exportfx hasn't been run. try exportfs -rv
* blocked firewall.
* user (root in this case) doesn't have rights on server.
* all the nfs daemons are not loaded, such as portmap in Slackware.

If that isn't it, hope someone has an answer.

Hi,

what kernel you are running? What NFS version? What machines?

A Sun solaris workstation can not mount an exported NFS directoy without
some changes in configuration.

It is possible to temporarily export a directory with the exportfs
command. Try this one.
There are some file in /var/lib/nfs which are needed for managing the
exports try to delete them. But some of them must be recreated with
touch command.
Try running the nfsd in debug mode. It then writes lots of messages into
your logfiles this may help to find the failure.

Try without root_squash, first.
Can you make sure root UIDs are same on both machines?
Can you make sure /tmp/test is owned by root on the server?
What you run exportfs -arv, were there any error messages?
