How do you guys quickly sync your settings (especially bash aliases and ssh keys) across your machines?

Ideally i want a simple script to run on every new server I work with. Any suggestions?

    I suggest you don’t sync SSH keys. That’s just increasing the blast radius of any one of those machines being compromised.

      Exactly this. Don’t move private keys between machines. Generate them where you need them, it’s not like they cost anything

      I mean, you want to copy the public keys that represents your machines, right?

        Fair point, but I would equate that with syncing the authorized_keys file rather than thinking about how to sync the keys.

      Right. Use some kind of centralized authentication like freeipa.

      For bash aliases, I just pull down a .bashrc from github gists.

        OP should just generate a unique SSH key per device (+ user).

          Agreed. I’ve probably got 100 keys registered with GitHub and 98 of them the private key is long destroyed due to OS reinstalls or whatnot. Format machine, new key. New machine, new key.

            FYI: You can remove the old keys from GitHub.

          I d rather have 2 to 3 (for critical, mid, and test systems) ssh keys that are regularly rotated than 1 key per machine. I m not gonna balance 50 ssh keys; neither enter my password every time i jump hosts.
