Application path and listening port

Question

I'd like to know which application that is listening on a port on a linux machine.

There are multiple servers, apache and what not on a single machine and I'd like to know which server is listening on which port without having to dig through the configuration files of each server.

Is there a command that lists the path to the executable and which port it is listening on?

Answer 1

netstat -t -l -p will list the listening ports and the pid and process name that created the socket. Since you have the pid you can use ps PID to find the path to the executable.
