I working on a project where i need to make a web host fully functional. My boss said there are tools called Web host managers so that we can manage our server from a distance and to let the "buyers" manage their own websites too.

My problem is that all I can find is something called Cpanel, which is a very powerful tool from what I can see, my only problem is that it isn't free, but when i try to look for that kind of software all I get is software with outdated "HOW TO".

Do anyone know any software of this kind that has a ubuntu tutorial or something like that?

Thank you
