Nodogsplash

Nodogsplash is a program that creates a captive portal.
Captive portals are the controls / webpages that restrict access to wifi networks. Modern devices auto detect captive portals and even prompt you to enter the web page. So combined with karma on the pineapple, we now have a device that actively is trying to show content to wifi devices.
