I'm taken with the idea of starting my own small and low budget ISP, please tell me if I've got the right idea. From what I've read so far, I need modem's, then some sort of multi i/o cards to connect to a Linux server, and then the linux server is on a LAN with a router (which I believe you can use an old linux PC for) which actually connects to the internet backbone. I can probably afford all these things (if I'm correct) but I'm unsure of where the software for such comes from. I found a linux router but what software do you need for the other server, to handle dialin access, and all that stuff, or is this already built into linux already? Is there a decent resource on the net which would show somebody the way to do all this? Or is there a software product you should buy to do this already?
I'm sure lots of people have had to go through this.
