Our church wants me to help them setup a "Login System" for their internet.
We run a Youth Group, and want them to be able to login with a username and password to be able to access any "internet" related service.

I remember McDonalds having such a system, where when you would open up your Internet Browser, it would lead you to the McDonalds "login" page (and wouldn't let you go anywhere else, all pages automatically redirected back there) and you couldn't do anything until you logged in.

Is there free software (open source a +) that allows you to do this? How about monitoring what there browsing?

(NOTE: Would we have to have a separate computer with two ethernet ports to be able to do this? Kind of like having that computer act as a middle man?)
I guess you'd use the RADIUS service, talked about here:

And here's some info on setting it up in linux:

PS, I bet if you install ipcop for the server, it might have something built in for you:)
