Open source and networking hobbies led me to depoly a set of interconnected Linux servers:
This server is the internets access to all of my other servers, and the glue holding them together. I was using IPTables briefly but have moved to NGINX to forward traffic from specified ports onto private servers connected to it. This device doubles as a Wireguard VPN server which in the past connected servers on the same virtual network, however I have switched to reverse ssh tunnels to connect other servers to this one. The VPN is still useful for odd networking tasks and troubleshooting.
Running on Raspberry Pi, this servers main job is to run Subterstrike servers, Minecraft servers, other game servers, and this website you're looking at.
A powerful computer with an RX 6950 XT GPU runs my local generative AI servers including Invoke AI for Image Generation, Ollama and Open-WebUI for LLM services. As this is also my primary device with a few spare terabytes of NVMe storage it contains a VSFTPD file server. By the way, this server runs on Arch Linux :)
An ancient gaming laptop with significantly more computational performance than physical durability was promoted to server, where it runs my Nextcloud self hosted office suite. While originally this was a 'because I can' project, I felt justified when I later saw Microsoft announcing USA demands come before Canadian privacy.
