That's identd, not inetd. Various servers on the internet will attempt
to connect to your ident port when you try to connect to them. If you
drop packets (what Shields Up calls "stealth mode"), they'll wait for
the attempt to time out before letting you proceed. If they get a
connection refused, they'll continue immediately.
