What Others Think

Just a small remark for FreeBSD users: On FreeBSD lsof works, too, but you have to install it first from the Ports Collection. I recommend to use "sockstat -l" instead on FreeBSD. It produces much nicer and more useful output, and it's part of the base system so you don't have to install any additional software.
