[linux-help] Re: interfaces..

[Jonathan Hall <jonhall@xxxxxxxxxxxx>]

I'm not really sure what you're trying to accomplish, but here are a coupe
thins that might help:

1) The only way to assign multiple IPs to a single interface is with IP
aliasing (i.e. eth0:0, eth0:1, etc)

2) You can (if you have kernel support for it) use a 'dummy' network
interface.  dummy0, dummy1, etc.  It doesn't connect to any hardware at all,
it just acts like.. well, a "dummy network interface"  You can ping it,
connect to it... even route to it if you really want to.  But the only
machine that will be able to use it is your local machine.  It won't respond
to any requests sent out over your ethernet interface, in other words.
