Alias names for network devices?

Alias names for network devices?

[Stephan von Krawczynski]

Hello all,

does anybody have an idea how to map a static device name to a network device
with dynamic appearance (e.g. ppp) ?

What I mean is something like:

static name : customer1
dynamic name: ppp25

The mapping should be made available at ip-up time, or better there should be
an _empty_ device which can be mapped on some existing dynamic device name and
should become empty again after its removal.

I know this sounds like a user-space question, but the kernel-question behind
is: is this concept possible at all? Can some userspace tool be written to
perform something like this?
The usage pattern is obviously doing SNMP statistics on users with varying
interface names.
Don't beat me for the subject line, I know alias ethernet devices are meant to
be something else, but how else would you call a second name for an existing
device?

Regards,
Stephan

Yes, you can rename interfaces easily.

For ppp the best solution is to patch pppd to do it.
