In this tutorial, we will be showing your how-to setup a Raspberry Pi Captive Portal by utilizing the popular nodogsplash software.
A Captive Portal is basically a screen that will be shown initially to anyone who connects to your Wi-Fi Access Point. Before they can begin utilizing the Wi-Fi connection they will need to complete an action, until they do that they will be continually greeted by the captive portal.
You can display whatever you want on the captive portal, so it can be highly useful if you want to layout some ground rules to using your Wi-Fi access point before a user gains access to it or whether you will require them to login before getting access.
