Also note that this form is deprecated. Alexey has a tool called 'ip' which
if you're familiar with cisco, should be second hand.
It does not use "eth0:x" form but uses the proper tag of secondary.
ip address add 1.2.3.4/24 brd + dev eth0
ip address add 1.2.3.5/24 brd + dev eth0
...
example:
# ip a s eth1 (ip address show)
6: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 100
link/ether 00:a0:cc:54:e1:eb brd ff:ff:ff:ff:ff:ff
inet 208.129.67.66/26 brd 208.129.67.127 scope global eth1
inet 208.129.67.67/26 brd 208.129.67.127 scope global secondary eth1
inet 208.129.67.69/26 brd 208.129.67.127 scope global secondary eth1
This tool is much more advanced and replaces ifconfig and route. It's use
should be encouraged. The program source and a command reference are listed
below.
