→Establishing a Secure Remote Desktop Session
Before a secure connection is established the SSH server must be installed in the desktop to which the connection is to be established. For detailed steps on installing the SSH server on an Unbuntu Linux system see [[Configuring Ubuntu Linux Remote Access using SSH]].
Once the SSH server is installed and active it is time to move to the other system. Once at At the other system , log in to the remote system using the following command, which will establish the secure tunnel between the two systems:
<pre>
</pre>
where ''hostname'' is either the hostname or IP address of the remote system. Log in using your account and password. The secure connection is now established and it is time to launch vncviewer so that it uses the secure tunnel. Leaving the ssh session running in the other terminal window, launch another terminal and enter the following command:
<pre>
</pre>
The vncviewer session will prompt for a passwordif one is required, and then launch the VNC viewer providing secure access to your desktop environment. If you are connecting to the remote desktop from outside the firewall keep in mind that the IP address for the ssh connection will be the external IP address provided by your ISP, not the LAN IP address of the remote system (since this IP address is not visible to those outside the firewall). You will also need to configure your firewall to forward port 22 (for the ssh connection) to the IP address of the system running the desktop. Steps to perform port forwarding differ between firewalls, so refer to the documentation for your firewall, router or wireless base station for details specific to your configuration.
