Disabling one NIC

[John O'Loughlin]

In /etc/sysconfig/network-scripts

you will see the scripts for starting your  network interfaces, ifcfg-eth*

in ifcfg-eth1 the line ONBOOT should be set to no, so it won't start on a 
reboot (or rather when networking is restarted).

Then take the interface down with ifdown eth1
