      Ok so stepping back from your approach, I have my pub keys copied to each server, why am I being prompted for the id_rsa passphrase, and root password?

      To each? Just to one, right?

        @Reid-Cooper Correct, I only want to rsync files from one server to the other, not both ways. Using the keys generated.

          Using the rsync command above, I'm still prompted for the admin password of the target server.

          Which the goal is to solely use the public and private keys for this.

            Which when I provide the password, the rsync operates without issue.

              If you enter a passphrase during the keygen sequence you will need to enter a password to enable use of the ssh key. So, did you enter a password in the questions asked during the keygen?

                I know it's so very counter intuitive at first, but enabling key only authentication means you can't enter anything at that point, just enter through those two questions.

                  So to reiterate, here's what I'd do:

                  If you don't need elevated privileges use a regular account.

                  ssh-keygen -t rsa -b 4096
                  

                  Just enter through the prompts

                  Then:

                  ssh-copy-id -i user@remotehost
                  

                  Then do the same for the other machine.

                  What's your output of ls -lZ in the /home/user/.ssh/ directory?

                  $20 says if you just did a touch authorized_keys it's going to have the wrong permissions/context.

                    It is not counter intuitive at all. it is a second form of authentication. Key + Password. He just messed up and set it up that way. He needs to redo the key without a password.

                        I did say "if" he manually created that file. My initial $20 is with yours.

                          I did not (just enter through), doing it now.

                            Wow, so simple, but still when attempting the rsync operation, I'm being prompted for the remote server root password.

                            Any ideas on that?

                              Nevermind, seems to work when I don't bother telling the system to use the authorized key.

                                That IS kinda the idea. ssh just handles that for you, even when called from another program like rsync.
