High Availability Pi-Hole Servers

Posted on 9 June 2024 by matthannan

Had been running a single Pi-Hole for a long while, but I would always have to wait until after C & J were abed before I could update it.

Having a second Pi-Hole server running was key. Was trying to get the second one spun up as a Docker instance on the Synology NAS, but trying to keep the two servers in sync was not going to be easy going, as ssh is key to this process.… Read the rest

HOWTO Update Portainer

Posted on 8 October 2023 by matthannan

I’ve set up my Portainer servers slightly differently than the official docs. They map to port 9443 and I map to port 9000. No big whoop, but it will stop me dead.

This is what it should look like:

user@docker:~$ sudo docker stop portainer
portainer
user@docker:~$ sudo docker rm portainer
portainer
user@docker:~$ sudo docker pull portainer/portainer-ce:latest

Posted on 12 September 2023 by matthannan

I am on my end of summer vacation and working through some psychic backlog items. Don’t get me started on Wireguard VPN. Grumble, grumble. But I am kind of relieved to have spent the morning screwing around with note applications again.… Read the rest

Privacy is increasingly a priority in my design decisions when it comes to what I what I am implementing in my home network. I am loathe to describe it as a “homelab“, as this is about as front-line production as it gets.… Read the rest

Further Adventures with Music on Raspberry Pi

Posted on 11 June 2023 by matthannan

I have a Raspberry Pi 3B (not the Plus version) with a HiFiBerry Digi+ DAC HAT attached. This is connected to my old school Sony receiver via TOSLINK fiber. I also have a 10.1″ touchscreen attached. The goal of all of this was to build a digital jukebox to play my music collection through.… Read the rest

Summer Vacation 2023

Posted on 19 May 2023 by matthannan

Legoland in Upstate New York. Definitely a good time.

The park was much larger than expected, and it is built on the side of a mountain, so it was easy getting to the lower level early in the day, but oh so rough coming back up at the end!… Read the rest
