ZoneCD is a Linux distribution to easily set up Wifi hotspots, distributed as a Live CD.It is derived from Knoppix (in this case, through, the Morphix variant.)The ZoneCD, utilizing a captive portal, allows hotspot operators to require a customer to login before accessing network resources. The ZoneCD itself is set up on an unused computer at the hotspot location, routing traffic between the wireless access point. When a user associates with the access point and tries to reach a website, the captive portal returns a login screen which can be customized to provide information or deliver an advertisement for the venue--such as a library, coffee shop, or restaurant.
