Lab fun with Docker, Pi-Hole, Nginx Proxy Manager, and Cloudflare Tunnels. My goal was to create a DNS over HTTPS Docker-compose stack that is portable and easy to deploy. With DNS over HTTPS (DoH), DNS queries and responses are encrypted and sent via the HTTP or HTTP/2 protocols. DoH ensures that attackers cannot forge or alter DNS traffic. DoH uses port 443, which is the standard HTTPS traffic port, to wrap the DNS query in an HTTPS request. DNS queries…
A little over 50 years ago, a few weeks before emigrating to the United States, I unwittingly stole a book from the Southerton Primary School library in Rhodesia (now Zimbabwe.)

The people I met along the way made the wins and losses memorable, I’m forever grateful to them. Above all, I could not have done it without the balance, support, and motivation provided by my…
Lately, I’ve been on a tear shutting off as many device LED’s as I can. Note to self: stop walking around in the dark. Love me some Pi, but wish they made LED management consistent across versions or provided a utility to do this automatically. The terminal can display which model of Raspberry Pi is currently in use, including the name of the family and the version. To have the terminal display the model of Raspberry Pi Add the following…
