Does it make sense to install ssh as non-root under UNIX?
You can install and run a ssh binary, which you can use to log into another system on which sshd is running. If you want to log in to the remote system without typing in your password, you’ll have to generate a private key in your home directory using ssh-keygen, then put your public key into $HOME/.ssh/authorized_keys. You can also start up sshd yourself as non-root, supplying the -p option so it binds to a non-privileged port (>1024), and then connect from another system with ssh -p. This will only allow connections to your own account, and sshd will, as a rule, not be restarted when your machine reboots. You will have to decide wether this is useful for you or not.
