Fair enough. To be on the safe side, I've setup my 2 servers to have access via RSA to one another. So if I loose my private key I will be able to ssh from another server.

If you use ssh keys and turn off password authentication via ssh, do I really need 1,2,3 ?

But, in this case there is no such thing as a server's public key, hence nothing to publish. So, loosing my private key = loosing access to server. Correct?

As far as I understood from the manual, you generate and store your private key on your machine and upload your public key to a server's authorized_keys file. Is this correct? Or the other way around?

Good idea, thank you. Are there any brute-force attacks against RSA?
