Device (LAN Cards) Naming

Device (LAN Cards) Naming

Hi to all!

I have a question about network interface naming in linux 2.4.x or 2.2.x

Is it possible to define a name for each interface instead of having
eth0, eth1 etc?

I'm using a linux box dedicated for routing & filtering and I would like
to have descriptive interface names such as:

public, private, branch etc...

so the output of ifconfig (and all other commands dealing with
interfaces) would be more 'concrete'

Is it possible? How?


Thanks a lot!

ip link set eth0 down
ip link set eth0 name buggy
ip link set buggy up

Ohh, nice!

Though I've gotten used to ethX, I'm sure this can help make scripts a bit
easier to read.

Does the new name work with ifconfig?

Yes, it does.
And with firewalling, shaping, etc - with everything that uses ethX.

Only programs that think they are smarter and use hardcoded
interface-names/schemes/lists are obviously broken.
