[ubuntu] Apache serving multiple web pages on ONE MACHINE, ONE IP ADDRESS. Help setting up

view story

http://ubuntuforums.org – I have a SINGLE machine, I have a single IP address. It is running 12.04 server. I have apache running. I want to serve multiple websites from the single machine. I have been searching ALL over and have had little success in having this set up properly. All help appreciated, but please don't post and tell me to "Set up virtual hosts". Also, if you tell me to change any text inside any files, please specify WHAT files, this seems to be a big problem with this scenario is no one wants to specify. Thanks in advance! (Hardware)
