Anybody have any experience setting up a DialUp server with Linux? I am looking to use a distribution of Linux and make a small dialup server for like 5-6 dialup accounts to get internet access.

I was originally looking into a 2000/2003 server to do this, but funds have made the licensing a problem, so I want to go with Linux to save $$. I am trying to find a good resource for information on the topic, so if anybody knows somewhere to get some good documentation on this, it would be GREATLY appreciated!
