[TriLUG] multiple IP from the same network card?

[Jeffery Painter]

I believe this is called multi-homing

I've set it up with little effort on redhat boxen before.

devices are named like eth0:0 eth0:2 eth0:3 etc... you have config files 
for each virtual interface to your eth0 device in 
/etc/sysconfig/network-scripts/

so instead of just ifcfg-eth0, you would also have ifcfg-eth0:2 and on for 
each ip address you need to add. add the new addresses to /etc/hosts and 
reboot! read docs for more detailed info

it's not too bad
