Multiple IP's on one ethernet port

Multi-home hosts are possible, make sure that the kernel has "IP: aliasing support" built in. It appears as if you need at least one device named, for example, ethX. If you define, say, an ethX:0 and and ethX:1 then ifconfig won't show them, but if one of them is ethX then both show up OK.

Network configuration in /etc/network/interfaces:

iface eth0:1 inet static
        address 192.168.1.50
        netmask 255.255.255.0

For some reason pump doesn't like the :0 aliases so if you're using dhcp then it has to be on ethX.
