Process port-protocol form PID

Question

If I have process ID and I want to know the port and Protocol of this process is there any command in netstat or other help me?

Answer 1

netstat -aon will give you a list of open ports and what process (PID) has them open. You could then pipe the result to the find command to only list ports open with a specific PID.

For Example:

I want to see what ports process 820 has open

netstat -aon | find "820"

This will provide some false positives if there is a port number or process name that also contains the number 820.
