It wasn't running but now it is. However, I still don't seem to get
anywhere.

This is where the problem arises. I can't ping the other machine nor can
I telnet it (in fact, I can't even telnet to myself; I get "connection
refused".)
What would the "destination" be? I have two machines, mimosas and
arcadia, both connected to the router.
I tried putting this in /etc/hosts:
10.0.0.1 arcadia
10.0.0.2 mimosas
which I seem to remember, from a previous abortive attempt to set up
plip, was the way to go, but no luck. I also tried putting in the IP
addresses from the router; I could then ping one of them but not telnet
to it.
