What web based system admin tools are there for Ubuntu? Basically I want to setup a headless server at home and want to make it easy for my family to change some settings. I'm familiar with Webmin but want to see what other options are available.
eBox (now zentyal)
sudo apt-get install zentyal
Note that Webmin is not supported as it's not compatible with Ubuntu package management:
Ajenti is easy to install, easy to use and has powerful tools.
You can limit what they can access with Webmin. For others looking at this question, check out webmin.
Search for "webmin ubuntu" for instructions on installing because it is not a simple apt-get.
Depending on what you want on your server TurnKey may be worth looking at. They have different appliances based on Ubuntu 8.04 using Webmin as admin frontend.
