Webmin is a web based graphical user interface that you can use to help you administer a Linux box.
To install on Ubuntu or other Debian based distros, first edit sources.list:
sudo nano /etc/apt/sources.list
And then add the following lines at the bottom of sources.list:
deb http://download.webmin.com/download/repository sarge contrib deb http://webmin.mirror.somersettechsolutions.co.uk/repository sarge contrib
After exiting nano, issue the following commends:
wget http://www.webmin.com/jcameron-key.asc sudo apt-key add jcameron-key.asc sudo apt-get update sudo apt-get install webmin
Once you have it installed, browse to: https://localhost:10000/
You will be prompted for your Linux user name and password. Enter it, and you will be taken to the Webmin home page for your server.
