But be very careful when you do this

Have you ever encountered a situation where you needed to kill a process running on a specific port on your Linux machine?

You may be concerned that an application you are running is misbehaving or hogging your network resources or local CPU power. Such an application may even pose a security risk that you want to eliminate.

Whatever the reason, you can use the fuser, lsof, and netstat commands from the terminal (along with kill) to help you find and kill any Linux process using a port number. These commands work on most Linux operating systems, including Ubuntu.
