Better than netstat: lsof tells us who is listening to what

OK, so we have netstat to tell us which ports are opened for listening: $ netstat -n -a | grep “LISTEN ” Thanks, that nice, but what process is listening to these ports? For TCP sockets, it’s (as root): # lsof -n -P -i tcp 2>/dev/null | grep LISTEN The -P flag disables conversion from [...]
