It depends on what starts it. As for me, i'd suggest you to check
xinetd.

Try and see log files! First of all /var/log/messages, then the logs
produced by sshd, and so on. I do not know so much iptables, i prefere
PF under openbsd... but i suppose that iptables supports log files! at
the very least, you'd know something about the IP...
