It is far easier to debug and there can be problems using wildcards with NFS 
which I have encountered in the past.

OK, to start with what is the IP address of your server and client.
You can determine them by
/sbin/ifconfig

We will for this exercise call the Server 'A' and the client 'B'

Can you ping from 'A' to 'B' and 'B' to 'A'?

----------------------- Server --------------------
On the Server 'A' run the following command
ps -ef | grep nfs

You should get something like the following
# ps -ef | grep nfs
root      4220     1  0  2004 ?        00:00:00 [nfsd]
root      4221     1  0  2004 ?        00:00:00 [nfsd]
root      4222     1  0  2004 ?        00:00:00 [nfsd]
root      4223     1  0  2004 ?        00:00:00 [nfsd]
root     26902 26882  0 21:31 pts/1    00:00:00 grep nfs

then try 
# ps -ef | grep portmap
nobody    4138     1  0  2004 ?        00:00:00 /sbin/portmap
root     26904 26882  0 21:32 pts/1    00:00:00 grep port

If you do not have either a nfsd or portmap process running, start them (as 
root) by the following commands 
rcportmap start
rcnfsserver start

This is an entry from my /etc/exports file on my server.
/home   10.21.132.0/24(rw,sync)

------------------------ CLIENT -----------------------

Do you have a mount point for where you are going to mount the NFS share?

To test the NFS connection create a mount point /mnt/tmp by command
mkdir /mnt/tmp

Now try to mount the NFS directory by

mount -t nfs <server-IP>:/home/kevin/k-shared /mnt/tmp

replacing <server-IP> with the IP address of the server

Does this work? If it does then umount the NFS share and look for any mistakes 
you may have made in /etc/fstab  

---------------------- DEBUGGING --------------------

Install the rpm 'nmap' if it is not already installed.

From the client 'B' run the command 
nmap <server-IP>

you should see an entry for NFS in the output like so:
2049/tcp open  nfs

If you don't then have you got firewalls running? You must have the nfs port 
open on the server.


That will do for now. Please report back and we will go on from here.
