The instructions tell the user to generate the id-rsa in root's .ssh but then the daemon is made without the proper permissions. We need to ether make it so that all the keygen stuff is happening on the local user or the systemmd deamon is made so that it has permission to grab that key. In this case I just rooted the daemon

You can run ssh-chat on port 22, but then you'll need to change the port of OpenSSH to something else like 2022. You can do this in `/etc/ssh/sshd_config`. Two services can't run on the same port like this.
There are two popular Service Managers for Unix-Like systems, OpenRC (BSD systems) and systemd (Linux). Eather one must be set up to run ssh-chat as a service (in the background). ssh-chat can be run as a user (not a daemon) but will stop servicing once the running user exits the terminal instance.

Make sure all your paths are readable by the user you're running as. If it's `User=nobody`, then they need to be readable by everyone. It's best to make a separate user just for your ssh-chat service and use that.
