Hi,all:

Yesterday I want to use the ip_alias in kernel-2.1.78, I find I cant use.
I check the files list in linux/net/ipv4, there is no ip_alias.c, I
remember it can be use before 2.1.67.

Who can tell me how to do ip_alias in kernel-2.1.78? Thanks.

It works.

Turn IP alaiasing ON - not a s a module. (I think this is the only option
available).

It works pretty much as before....

I'm using it now: (addresses obscured to protect the names os the innocent

I think there may be a few net-tools bugs about - but these shouldn't affect
you (other than apparently delted route will still appear in the output of
route).

Presumably Phillip has a fix for this already?
