You can forward a port on your local machine to another machine and it's also possible to forward a port on a remote machine to another machine. In the following examples, you will get a shell prompt once the forwarding is complete. Keep this shell open to use the port forward and exit it whenever you want to stop the port forward.

1. This command will forward port 8000 on your local machine to port 80 on www.kernel.org:

        ssh -L 8000:www.kernel.org:80user@localhost 

Replace user with the username on your local machine.

2. This command will forward port 8000 on a remote machine to port 80 of www.kernel.org:

        ssh -L 8000:www.kernel.org:80user@REMOTE_MACHINE 

Here, replace REMOTE_MACHINE with the hostname or IP address of the remote machine and user with the username you have SSH access to.
