Subject: slip interfaces

Hi,

Slightly offtopic but this list is probably the most likely to have
people who know the answer...

I've got a requirement to filter traffic for a given SERIAL DEVICE
connected via slip..

Now as people may or may not know slattach creates sl# interfaces in
the order slattach was called... on our system there is no certainty
that sl0 will always be /dev/ttyM3 for instance.

Is there anyway to identify from anywhere (inc the /proc and
/sys/class/net fs) which sl# maps to which /dev/ttyM# number?

Thanks,

Richard.
