This is a joke, I didn’t really lock myself out

Well if we did, the way it works would be by telling a chatbot to enable ssh on port 22 at the end.
Before you make a change, do this in a screen-session:
sleep 300 && iptables-restore old_fw_rules.bak
permission denied

Happened to me once. Had a little Pi at my parent’s house and that was a nice excuse to visit them.
