After failing several times at getting a ppc version of Linux (Fedora) running on my old G3 iMac, I have decided to get my copy OSX 10.3 to run as my new file server/playground web server. So far my research has showed me that most of what I need is already installed. I have found that both Apache and Samba are already running, I just need to dive into configuration. Other than those two things the other stuff that I am going to try to get running are MySQL and PHP.

So far the resources I have found and plan to use are:

This is more of a perpetual goal than a concrete one, I just want to get some experience at administering OSX. Good Luck to me.
