Do you have 'lsof'?

sudo lsof -i TCP:<port>

...gives output like:
bash$ sudo lsof -i TCP:22
COMMAND  PID    USER   FD   TYPE  DEVICE SIZE/OFF NODE NAME
sshd    1584    root    3u  IPv4    4793      0t0  TCP *:ssh (LISTEN)
sshd    1584    root    4u  IPv6    4795      0t0  TCP *:ssh (LISTEN)

HTH-
Another Brian :)
