Hello Binu,

If you want it to be permenent:

cd /etc/sysconfig/network-scripts

cp eth0 eth0:0

Edit it, make sure the inside reference says eth0:0 instead of eth0.

Some prefer eth0:1

cest la vive

service network restart

or if you need a 100 IPs:

create a file
/etc/sysconfig/network-scripts/ifcfg-eth0-range0

Containing something like...
IPADDR_START=xxx.xxx.xxx.1
IPADDR_END=xxx.xxx.xxx.100
CLONENUM_START=1

and do:
service network restart
P.S.
The ip addresses must be in the same subnet as the primary card (i.e. if you create ifcfg-eth0-range0,then use the same subnet as eth0).
