**Remember**: the first vnc connection will start at port 5901 (:1), the second connection at port 5901 (:2) and so on. The same for the port **8899**. Only 1 user can connect to this port. If this port is occupied, you can't get a connection, so you have to try another port, for example: 8900 or 8898, etc.
#### Closing the reverse SSH tunnel
* vncserver -kill :1
* close both connection/terminals where you are logged in [to the ssh proxy server] with "exit"
