how to turn my server into a host ?

Hey all,

i would like to host websites on my server maybe do a free hosting system but i might work privately, which ever my clients will most prob need access to their space and what not so ofcause they will need a control panel and everything to check the space they have left and what not now this is going to be a hobby type thing and not a company so i dont really want to spend that much money if anything at all so does any one know of any good hosting scripts that i could use?

thanks for your time and sorry about the stupid question

There's a good tutorial here on setting up Ubuntu as a webserver, including control panels for easy administration. There are lots of other good guides around the Internet.
