  1. Open the Terminal window by pressing Ctrl+Alt+T or going to the Applications menu and selecting "Terminal".

  2. Type ssh [remote-host] where [remote-host] is the hostname or IP address of the remote server you want to connect to. Replace [remote-host] with the actual hostname or IP address.

  3. Press enter to establish an SSH connection to the remote server.

  4. Once connected, type tun0 to create a new tunnel interface on your local computer. This is the name of the tunnel interface you will use for data transfer.

  5. Type sudo ip tuntap add dev tun0 mode tap to enable IP forwarding and set up the tunnel interface. You may need to enter your password when prompted.

  6. Type sudo ip route add default via [remote-host] to add a new route to send all traffic through the SSH tunnel. Replace [remote-host] with the actual remote server hostname or IP address.

  7. To access resources on the local computer over the SSH tunnel, use the --local-addr option in ssh commands. For example, if you want to access a web page on your local computer while connected remotely, use:
    -L 8022 [remote-host]:[local-port]
    where [remote-host] is the hostname or IP address of the remote server and [local-port] is the port number of the resource you want to access on your local computer. The : between [remote-host] and [local-port] indicates that this command establishes a new SSH tunnel. Replace [local-port] with the actual port number.

  8. To close the SSH tunnel, simply type exit.
