A simple bash script to replace the
authorized_keys file on each of your servers with a provided list of public keys.
- Clone the repo
- Edit the
serversfile and add each of your servers to the
- Copy each of your public keys (typically located at
~/.ssh/id_rsa.pub) to the
This script replaces the existing
authorized_keys on each server.
If you need a specific public key to access any of your servers, make sure you've copied that key to your
pubkeys directory before running
key-sync or else you'll lock yourself out of your server!
This tool is intended for people who need to connect to a number of different servers from a number of different workstations and want to have a different key pair on each (a good idea from a security perspective as you can selectively revoke keys if you e.g. lose your laptop).
I suggest that after you've cloned the repo and added your own pubkeys and servers, you commit to a new branch and push that to your own (probably private) git repo. This way you have the public key from each of your workstations and your server list easily accessible and modifiable. When you need to add/remove a key/server, do so, run
./key-sync and push the changes back to your repo.
