Something similar to netstat ... but quicker.

Oh, I'm not interested in keeping a log.  This request falls under the
'cute-but-pointless' things to do section.  You see, every time someone
fingers me, a program runs and creates an up-to-date .plan file.  I'd
like to know where the finger is coming from in order to further
embellish the info.  Ideally, I'd like to know who is reading the .plan,
so I could figure out who is fingering me locally, or decide that it's
remote and then use figure which finger connection they are coming
through.  I don't think it's possible ...

Turns out 'netstat -n' is fast enough, and actually better for this
purpose than 'netstat' alone.  Thanks to the people who set me mail
suggesting this!
