Today I had to install Ubuntu in a Virtual Box on one of our servers. Accessing the Ubuntu desktop via the remote desktop connection was rather slow, so I decided to enable the remote desktop on VNC. I enabled it without any problem. They make it really easy. The issue I had was the default port 5900 was not opened in the company firewall. I did have another port available so I went to change it. All the documentation I found said there should be an advanced tab but there wasn’t. Finally after some Google searching I found this link:

The brief summary is:  You open up the gconf-editor and set an alternative port, check the checkbox that says “use alternative port” and then reboot. Easy as that!

Dave is my hero today.  Thanks Dave!
