[K12OSN] multiple LTSP servers same network: tips/ tricks/ handouts

[Petre Scheie]

Note that iptables (the firewall) on the client can prevent NFS mounts from 
working, too.  Start with 'service iptables off' on both machines to see if it 
matters, then go back and modify the /etc/sysconfig/iptables file to open the 
necessary ports.
