Plugging in ethernet

[Scott S. Condie]

A question for those that know more than I.  I was able to get ydl 
3.0.1 running on my Wallstreet Powerbook (thanks to all those that 
helped) and now have a question about ethernet.  When I start the PB 
with the ethernet cable plugged in it works like a charm (i.e. I can 
access the internet), but I can't figure out how to tell the computer 
that the cable is plugged in if I plug it in after the computer is 
on.  This is useful if I am working at home and then need to go to 
work and just want to put it to sleep instead of shutting down for 
the trip.

I believe it has something to do with the 'eth0 interface' that is 
mentioned in the log from the start up script, but I don't know what 
that is or how to make it work outside of startup.

Your help is appreciated.
