You don't need nfs running on the client. 

You didn't show what the server is exporting, to whom, permissions, etc. 
Are you actually exporting /pub to 192.168.1.0/24 ? 

If you have a firewall, you must open some ports on the server in order 
for any client to connect to the server. Try without the firewall first.


What I do and works as expected is this:

On the server run system-config-nfs

Add the partitions you want to export to 192.168.1.0/24 with whatever 
permissions you want. Then click on the "Server Settings" and force the 
nfs daemons to run on designated ports of your choice. E.g. 4000 - 4003. 
Quit system-config-nfs and restart the server: /etc/rc.d/init.d/nfs 
restart.

Still on the server side, open up in the firewall the ports 2049, 111 and 
the ports you used in system-config-nfs (in my example 4000-4003). Both 
tcp and udp.

On the client side just install and run autofs. Then, from any client 

cd /net/lion/pub 

and you're there. No need for cryptic mount commands in /etc/fstab 
(although, of course, you can go that way too, if you want). The 
automounter will do the work for you, on demand. 



Diagnostic: on the client, as root:

showmount -e lion

You should see the partitions you are exporting. 

rpcinfo -p lion

You should see which ports the nfs daemons are running on. 

The most likely problems are always the firewall and/or improper server 
configuration. 

If push come to shove, use wireshark to see the traffic between the 
client and the server.
