Captive Portal on BrainyPi

Description: A Captive Portal is a web page that the user of a public-access network is obliged to view and interact with before access is granted.

Steps to Install:

Update the OS using below commands before installing captive software by just copy pasting the following lines into a terminal:
```
sudo apt update
sudo apt upgrade
```
Now for installation run the below command.
```
sudo apt install git libmicrohttpd-dev
```
We can get along with setting up our captive software, nodogsplash.

nodogsplash is a somewhat lightweight captive portal solution that is easily set up and highly configurable.
To get this software off their git , clone its repository with the following commands.
```
cd ~
git clone https://github.com/nodogsplash/nodogsplash.git
```
We can now proceed with compiling and installing the software by typing the following commands.
```
cd ~/nodogsplash
make
sudo make install
```
We can now make some modifications to the configuration file by typing the below command
```
sudo nano /etc/nodogsplash/nodogsplash.conf
```
We need to add the following information, this tells what interface the nodogsplash software should show up on and what address it should be listening on.
```
GatewayInterface wlan0
GatewayAddress 192.168.220.1
MaxClients 250
AuthIdleTimeout 480
```
Now save and quit out of the file by pressing CTRL + X then pressing Y and then ENTER.
With our changes to nodogsplash’s configuration saved, we can start up the software by typing the following command.
```
sudo nodogsplash
```

Installation will be completed.
