[Help-gnu-radius] Wi-Fi Provider

[renato . s . silva]

Hi,

I'm trying to mount a Wi-Fi provider and I'd like to use a radius
authentication (802.1X). Can you send me the best radius configuration for
this case ? My Access Point is DHCP server and my business model is like a
Pre-paid access. I'd like to konw how can the radius interrupt a user
connection after the time limit.
