Re: How to find which process is listeing on a given port?



Never mind - figured it out

sockstat(1) shows that this traffic is from my bittorrent server.

I've got a _lot_ of traffic hitting my system on UDP 51413, and a netstat shows that the machine is listening on this port for both UDP and TCP. netstat -A gives me the pcb address for the active sessions (but, apparently, not for the listener), but I can't remember how to figure out which process has that pcb/file open.
