SSH connection without password between two linux machines

Instructions

  1. Generate the files: [id_rsa], [id_rsa.pub] in the First Machine by typing at command (do not use a password – just hit Enter*) :
    ssh-keygen

    * You don’t want to enter any passwords, because you want to call ssh from a within a shell script.
    ** The randomart is an easier way for humans to validate keys.
  2. Copy (and rename) id_rsa.pub to authorized_keys on Server (run from the same computer you run ssh-keygen);
    scp -r -P 22 /root/.ssh/id_rsa.pub destination:/root/.ssh/authorized_keys<em>
    </em>
    Where destination is server B.

Now you can connect as root without a password between the servers.
