Hello Joe,
Unfortunately ip aliasing etc are from 2.0 and 2.2 kernel
networking and are deprecated in the 2.4 kernels.
To be correct here, the notion of IP aliases as physical interfaces has
been dropped in 2.2.x kernels already. I think it was somewhere around
2.1.128-137.
It was then replaced by the concept of having labels as aliased (stupid
name anyway) interfaces. So we still have sort of aliases but they are
not physical detached devices in the kernel context anymore but only
additional (most of the times secondary) IP addresses.
Presumably they will be dropped in 2.6. They are
I'm not sure there, as aliases are just names and nothing else in the
kernel. Simply a string ;).
being replaced by the much more difficult to use
policy routing tools eg iproute2
YMMV but ip (from the iproute2 package) is a very intuitive tool once
you worked enough with it. Also you neglected to mention that with ip
you have _one_ single tool to handle arp, ip and routing, whereas in the
old days you'd need three tools (arp, ifconfig, route). It goes without
saying that those tools are quite b0rked.
Best regards,
Roberto Nibali, ratz
