You must be careful using ifconfig ethx:x down. If you run more than one virtual interface on a network card taking one out of the middle will move the list up. Say if you have 4 virtual interfaces of which the first is the real eth1. So if you take out eth1:2 then eth1:3 becomes eth1:2 and eth1:4 becomes eth1:3. This may confuse some scripts that deal with virtual interfaces. Beware. Little late with this but what the hey. You must be careful using ifconfig ethx:x down.
