Sometimes having a simple GUI interface to do tasks on an internal server can be really handy. For that purpose and for free I use Webmin.
Super easy to install. Just copy/paste into SSH.
sudo sh -c 'echo "deb http://download.webmin.com/download/repository sarge contrib" > /etc/apt/sources.list.d/webmin.list' wget -qO - http://www.webmin.com/jcameron-key.asc | sudo apt-key add - sudo apt-get update sudo apt-get install webmin
Here are the webmin install docs: http://doxfer.webmin.com/Webmin/Installation
UPDATE:
If that doesn’t work, try these instructions from Webmin: http://www.webmin.com/deb.html
