One of my client’s requirement is to have a Ubuntu server with a Desktop Environment. Once in a while he will call me up to look at some problem he is having with one of his GUI based application. Its not always possible for me to be physically be there to see what the problem is, so I use a trick that have saved me many times in the past. Its simply a remote desktop with SSH Tunneling, its very simple and easy to set it up. As the name suggest you will need SSH access for this to work.
First you will have to install x11vnc on the remote desktop that you are trying to log in to sudo apt-get install x11vnc and then create a tunnel using SSH ssh user@ip_address -L 5900:localhost:5900 "x11vnc -display :0 -noxdamage" now you can use a VNC client like ‘Remote Desktop Viewer’ to connect to localhost:5900 and you should be able to access your remote desktop. The quality of the display may or may not be ideal but its still simpler and quicker than setting up 100 firewall rules for a VNC server or setting up teamviewer.
Give it a try and let me know how it went.
