Hello,
We got a new machine in our lab and we installed RHEL5(Red Hat Enterprise Linux. We have our home directories on our cluster which I would like to mount on my new red hat machine. But, when I issue the following command

mount -t nfs cluster:home_dir mount_location

the mount command just hangs.

Similarly, I cannot export DISPLAY to my screen. I unable to open a simple gui application like xemacs.

But, I am able to ssh to the cluster and to my machine from the cluster. Is there any catch over here?

I made all the required changes for NFS client configuraton and server configuration.

Here is the output of rpcinfo:
#/usr/sbin/rpcinfo -p
