sshsync

Simple utility which I have written for myself for synchronization authorized_keys file on multiple machines.

It takes contents of file which stores on GitHub's Gist and just pushes into user's authorized_keys. Since ssh keys are public keys, it's totally safe to store them in open place.

Usage

1. Download binary automatically

wget -O - https://raw.githubusercontent.com/holy-filipp/sshsync/refs/heads/main/install.sh | bash

2. Set URL of source file directly or using special flag

./sshsync do -u https://gist.github.com/holy-filipp/064b9318240c56ce4cb0c5f7908ff226/raw/authorized_keys
./sshsync url https://gist.github.com/holy-filipp/064b9318240c56ce4cb0c5f7908ff226/raw/authorized_keys

sshsync url saves URL to config file, program prints location of this file on screen.

Other commands

1. sshsync crontab [optional url] - if URL specified, sets it to config, adds sshsync do to crontab for running each minute.

./sshsync crontab https://gist.github.com/holy-filipp/064b9318240c56ce4cb0c5f7908ff226/raw/authorized_keys

Disclaimer

This utility I wrote in two days, if you really want to use this, be careful. I didn't even test it at the moment.
