well then...
to add more ip's on the eth0 NIC do like this:
(considering ip1 is added to eth0)
ifconfig eth0:0 ip2
ifconfig eth0:1 ip3
ifconfig eth0:2 ip4
..and so on ..to how many ip's you have
but if you want these ips to be activated at system boot so you don't have to do this every time
go to /etc/sysconfig/network-scripts and create files named ifcfg-eth0:0 , ifcfg-eth0:1 ..and so on
and then you need to add information to them... for an example of what you need to add
look in the ifcfg-eth0 file which was already there (or at least it should be
)
Well anyway that's the way I do it and it works for me. if anyone knows a better, easyer way to do this please tell us
Good luck,
