Never heard of it before.

Excellent! This turns up the following:

tcp      888      0 192.168.35.10:42799     128.143.202.191:23     
ESTABLISHED1 3841/aprsd

Duh! Big red "ouch" starts fading in across forehead as the light comes
on. "host 128.143.202.191" returns "xenon.hscs.Virginia.EDU."
Sure enough, "/etc/init.d/aprsd stop" makes the traffic cease and the
connection drop. (Should've read some documentation, instead of simply
apt-getting the other day and thinking I'd play with it later.)

Many thanks, David! Now I'm off to learn about aprsd... after I get some
sleep. :-)

Thanks,
Jacob
