I need a simple open source hosting control panel that works. I don't need billing or registration, just the ability to add hosting accounts, databases, ftp, and mail. Anyone have any suggestions? Good documentation would also help.

I've never installed these but on another forum I read people where talking good things about web-cp or webmin & there was talk of DirectAdmin.

I would browse the features and try the demo's and then try one out'

try free ravencore very easy and simple to use, work well with centos http://ravencore.com

Another one that looks pretty good and its open source as well

Search for "ehcp articles" on google for more detail

There are several control panel programs like what you are looking for. When I was searching for one that worked good for me, I found that many of them had been abandoned so it is hard to filter through and find a currently supported one that works for you. I did find a list of currently supported Control Panel programs that is constantly updated to show the current release and they also remove any broken links or control panel programs that are no longer being supported. you can find this list at http://zzoox.com they also have install tutorials for these and other programs. The easiest to use and install is EHCP but as far as I know, it only works on ubuntu and debian and it does have the option for people to register but that option can also be turned off so that you can just set up the accounts you want to set up. They also list programs such as BlueOnyx (formerly BlueQuarts) and webmin but they describe it in better detail than I have time to do at the moment. Good Luck
