Erik et al,
I have managed to lock myself out of the payments host. I attempted to install ufw as a simpler interface on top of iptables and/or nftables, but after a failed attempt at the ufw installation, I'm not able to get in at all.
Erik: Sorry to have to ask you this especially in the middle of mailman migration, but I think you're the only one who maybe has access to a virtual console to the VM through hetzner. Could you have a look at the machine (payments.common-lisp.net) and see about opening up firewall for ssh on the standard port (I think i'm still running sshd on 22 on there)
If the VM needs to be wiped and reinstalled (hopefully not) then it won't be the end of the world - i can certainly reinstall the payments application -- but there are some log files on there which I would very much like to get off the machine if possible (all under ~dcooper8/ -- transaction logs for donations and print sales etc).
Sorry again..
Dave
