Creating a Captive Portal on a Raspberry Pi Access Point running on Alpine Linux

By: XtendedGreg as seen on https://youtube.com/live/vCRdlZjwhsE

Introduction

These commands will compile and install NoDogSplash, configure it as a captive portal, and start it as a service on Alpine Linux. This is useful for guest or customer networks where you would like to maintain access to the internet for temporary users, but do not want it to be exploited.

Equipment Needed

Raspberry Pi running Alpine Linux configured as an access point following this guide: https://gist.github.com/XtendedGreg/5ef72d27c0dd1dbf1f2e2125092e7369

Step 1: Clone and Compile NoDogSplash

# The screenshots I took, have resolutions 144x144
# The screenshots I took, have dimensions 2990x2080

# I combined all the front images  and back images of PCB separately into 2 separate videos, each with framerate 8 
ffmpeg -r 8 -f image2 -s 144x144 -i picf%04d.png -vcodec libx264 -crf 15  -pix_fmt yuv420p wf.mp4
ffmpeg -r 8 -f image2 -s 144x144 -i picb%04d.png -vcodec libx264 -crf 15  -pix_fmt yuv420p wb.mp4
# changed the resolutions
ffmpeg -i wf.mp4 -vf scale=2990:2080 -preset slow -crf 18 wfrs.mp4
ffmpeg -i wb.mp4 -vf scale=2990:2080 -preset slow -crf 18 wbrs.mp4
