This repo contains scripts to sync SSH public keys at the server with hackerspace's users' profiles. Add you public ssh keys to your profile at the hackerspace.by and run update_authorized_keys.sh on the remote server.

Install requirements

sudo apt-get install wget diffutils

or use other package manager to install wget && diff

Initial setup

At the first run, the script will make the copy of existing ~/.ssh/authorized_keys as ~/.ssh/authorized_keys.d/authorized_keys.local. Edit it if you need additional keys not synced with HS site or remove it otherwise.

The script will download file with keys of active HS users to ~/.ssh/authorized_keys.d/authorized_keys.hackerspace and then merge local-specific and downloaded files to one ~/.ssh/authorized_keys
