Lessons learned:
- Lots of debugging and installing operating systems.
- Learned some networking.
- Installing and using Armbian.
Description:
This was a summer 2023 project that involved setting up a Banana Pi to use PiHole on. The banana Pi uses a debian linux operating system called Armbian.
PiHole is an open source application that I did not make that monitors internet traffic and blocks trackers, advertisements or anything else you want blocked. After installation it acts as a DNS server and is online 24/7.
