For example, to show all listening TCP and UDP ports with process ID (PID) and numerical address: $ sudo netstat --tcp --udp --listening --programs --numeric Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Addr State PID/Program name tcp 0 0 0.0.

How do I know if port 443 is listening?

Enter "nc -zv + IP address or hostname + port number" (e.g., nc -zv www.synology.com 443 or nc -zv 10.17.xxx.xxx 5000) to run the telnet command and test the port status. If the port is open, a message will say Connection to www.synology.com port 443 [udp/https] succeeded!

What are non listening ports?

A non-listening socket is one where a connection has been made, for example, a web server where a web client, such as a browser, has connected, and data can be or is being transmitted. The port the socket was listening on is usually then also cycled back to be listened on by the same process or process tree.
