Hello,
I think it's easier done graphically from the network or by running
redhat-config-network from the terminal. You can edit the interfaces name
from here, knowing which is which. But you have to be clearly with this cos
if you don't do it well, the NICs won't start up.
Another option is by editing the /etc/sysconfig/network-scripts for the
ifcfg-* for the changes you want to make.
The last option (which I have not tested) is to edit the ifconfig-eth* files
themselves. The eth* name is always there and I think the mac address too.
The location of the files are /etc/sysconfig/networking/devices/* and
/etc/sysconfig/networking/profiles/default/*. The ifconfig-eth* must be the
same in both for it work.
Thank you and BR,
Mobolaji
/etc/sysconfig/network-scripts
