Distributing New SSH Keys Using Rsh On Linux And Unix

Today we’re going to grind through our “Lazy Sunday” post with a quick script to update SSH keys network-wide, by using rsh (the less secure of the two protocols). Once you’ve accomplished this (or have already accomplished this) and are happy with your network’s SSH setup, I’d suggest disabling rsh altogether. Then you can move on to quickly setting up your SSH keys all over the network, focus on maintaining the integrity of your sessions, if you have issues with that, and even setting simple SCP routines to help keep your network easy to manage.
