Network notes

Small-scale infrastructure: routing, tunnels, monitoring, and the configs I keep coming back to.

I run a handful of Debian machines and prefer boring, reproducible setups: plain files, systemd units, and scripts that can be read in one sitting. Most of what is published here started as a note to myself.
