When I do a port scan or netstat -a | grep LISTEN, I get something listening on port 5000. Netstat calls it "commplex". Even if I turn on the firewall, it's still listening. It only listens on my IP address, not on 127.0.0.1. I am not running any servers that I know of, and no chat/IM clients. I can add the output of "ps aux" if needed. Can anyone tell me what it is and how to stop it?
