You're the IT administrator for a small corporate network. You've set up an internal web server to do some testing. You would like to obscure the server some by changing the default ports.

Your task is to explain HOW to:

1. Use ss -lt and netstat to determine which ports the web server is running on.

2. Modify the ports.conf file to change port 80 to 81 and port 8080 to 8081.

3. Restart the web server to implement the port change.

4. Use netstat and ss -lt to verify that the server is listening on the new ports.

How do I do those things? Step by step please, I am a newbie and I do not understand the questions! I lack study materials on this subject and have found no sources online that explain it in simple terms.
