create ip aliases

logged in as root, from the command line, do the following:
ifconfig eth0:1 inet x.x.x.x y.y.y.y z.z.z.z

Where :
x.x.x.x is the ip you want to assign the virtual nic
y.y.y.y is the netmask for that subnet
z.z.z.z is the gateway for that network

The above changes will be lost when you reboot. If you want to make the changes permanent, find the file named ifcfg-eth0 and in the same location as that one create a new file called ifcfg-eth01. The file should contain the following:

DEVICE=eth0:1
BOOTPROTO=static
BROADCAST=x.x.x.255
IPADDR=x.x.x.x
NETMASK=y.y.y.y
NETWORK=x.x.x.0
ONBOOT=yes

You then need to look for a script called ifup and make sure that it includes the latest file you've just created.
