Isn't the "correct" method actually: # add address 10.0.0.2/24 (i.e. standard netmask and broadcast) to eth0 ip addr add 10.0.0.2/24 brd + dev eth0 # add address 10.0.0.3/24 (i.e. standard netmask and broadcast) to eth0 ip addr add 10.0.0.3/24 brd + dev eth0 I think the command reference that comes with it is great, and it's on the web too: http://snafu.freedom.org/linux2.2/docs/ip-cref/ This is a pretty good rundown on how it works: http://snafu.freedom.org/linux2.2/iproute-notes.html The tools are located here: ftp://ftp.inr.ac.ru/ip-routing/ --Erik Rev.
