detecting which eth0 config [was Re: gdm fails]
I used whereami (worked) and then guessnet (worked better)
and now a little script that's still a little rough.
Basically it outputs "work" or "home" or "site" based on
ifconfig eth0 up # bring up eth0 without ip
if arping <opts> <ip addr> | grep -q <mac addr>; then echo work
elif arping <opts> <ip addr> | grep -q <mac addr>; then echo home
...
ifconfig eth0 down # take ifconfig back down so ifup can doit 'right' for this net
I use the form of arping that's mac-only, but I don't
remember the opts for that right now.
Anyho, your script can then be put into the 'script' line
of your eth0 stanza (read man interfaces to find out about
the script line).
If you still need help tomorrow, let me know and I'll get
the full config off my laptop.
