I found myself with a weird connection problem at home on Monday morning. I could no longer reach my blog or any of the other services hosted either via my reverse proxy or the docker host behind it.
I thought I'd broken something on my work laptop at first but I was seeing the problem on other devices.
Long story short.... OpenBSD uses the pf firewall and has a tool to load new rules. It also has a way to test the rules before you make them live, to avoid mistakes, using 'pfctl -nf /etc/pf.conf'... well, over the weekend, guess who updated a few rules but failed to test them? Yep, this guy. So, when my backup routine ran on the VM in question overnight Sunday/Monday and restarted it, the broken ruleset prevented pf from starting, cutting everything behind it off from the world.
Every day's a school day. Some days it's college, others it's kindergarten.
I am so mad at myself. Stupid. Stupid. Turned on the Cifer after chip swapping/testing and found the keyboard didn't activate the usual disk message with ctrl+disc keys. And then the smell hit me... A burning smokey dying electronics smell.
Didn't take long to find it. Chip ML93 which is a 74LS126, was the temperature of the sun. I have destroyed that chip by making the dumbass mistake of putting it in the wrong way around. FFS.
I have massively underestimated the space needed for this #Jigsaw.
