I recently got myself a small VPS from Hetzner to play around with. Using their ‘rescue’ function you can mount different installer images in the virtual disc drive and install the system via VNC or web console.
They provide an Arch installer too, so I chose that. I set up a very barebones system on a btrfs partition and with an nginx webserver.

I dug a little further after my last post and stumbled upon this excellent blog post. It turns out that using the libpam-oath module for two-factor authentication is a lot easier than the challenge-response module and it works rather fabulously.

The idea was to use the PAM module in its challenge-response mode for authentication during SSH logins.

However, somehow I can’t get ghost to listen properly on sockets yet.. or at least nginx gives me 502 errors when trying to connect .. I’ll resort to using localhost:port for now.
