How can you test to see if a specific port on a remote host is listening?

One of the biggest perks of Telnet is with a simple command you can test whether a port is open. Issuing the Telnet command telnet [domainname or ip] [port] will allow you to test connectivity to a remote host on the given port.

Is PID same as port number?

To answer the question directly: there is no connection between the process ID and the port number. They enumerate entirely different things. The PID identifies a process (eg a Firefox session: each tab may run as a different process), and the port number identifies which port that process is using to communicate.

How to find port number by process ID ( PID )?

Why are some ports and PIDs listed more than once?

You’ll also see some ports and some PIDs listed more than once. That’s because one process can be using the same port number on different protocols like TCP, UDP, etc. Now to see the name of the process that is using that port, go to Task Manager by pressing CTRL + SHIFT + ESC and then click on the Process tab.

How to find a process using a specific port?

We can use the lsof command to find the process using a specific port with the -i :port_number option: The first four columns in the above output tell us the process name listening on port 22 and its PID, owner, and the file descriptor. We can pass multiple -i :port to the lsof command to find out the processes listening on various ports:
