How to check the port of the system?

Can be used with a command: netstat -lnp to view the port of the system currently listening. Where l option indicates a port that is listening (listen); n option means that the port number is displayed instead of being converted to port names by viewing / etc / service; the P option indicates the listening program.
E.g:
