Hmmm... let's figure out exactly what's going on here.

I would expect to see the URG packets from rlogin not rlogind, from
things like hitting Ctrl-C etc.

On the other hand, I can't imagine what the server, rlogind, would be
sending URGs out for.

So I would say that it is more likely to be rlogin sending the
URG packets.
