"fstat" is your friend -- it can tell you which process holds the listening socket descriptor. On FreeBSD you have to use 'netstat -aAn' first to find the address of the protocol control block (PCB), and then grep for that in the output of 'fstat'. For example: 12:44 [6] $ netstat -aAn | fgrep '*.80' c49e0a40 tcp4 0 0 *.80 *.* LISTEN 12:44 [7] $ fstat | fgrep c49e0a40 wwwsrvr thttpd 137 5* internet stream tcp c49e0a40 -- Greg A.
