mount NFS server timed out

[Andreas Redelbach]

Hi all,

I have set up a NFS server and try to mount the home directory of the 
server to some test directory:

mount ip-Server:/home test

After opening the relevant ports and checking the firewall, I still 
cannot mount, due to time outs, i.e.

mount to NFS server failed: timed out (retrying)
...

Since the server is properly set up running and wanted to ask for 
possible solutions.

Any systematic approach known?

Cheers,
Andreas
