Once you have your key saved on the server, you must copy the key string (remember, beginning with ssh-rsa and ending with to the /home/USERNAME/.ssh/authorized_keys file (Where USERNAME is the user in question). You must copy that entire string and transfer it to your server (by means of USB drive, email, or however you can get it there). The above command will output your entire public key that begins with ssh-rsa and ends with (Where USERNAME is the user name and HOST is the hostname of the machine).

To do this, log into the client machine as the user that will logging into the server. The first thing you must do is copy your public ssh key from the client machine. What we are going to do is copy the ssh public key from the client machine to the server. Should your platforms differ, you might have to alter the instructions slightly.

This option disables all ssh authentication, besides key authentication. Say, for instance, your security administrator requires PasswordAuthentication be set to no on your server (for security purposes). But there may be a reason you might want to copy that key manually. With the help of the ssh-copy-id command, that task is made incredibly simple. In fact, you might have already set up ssh key authentication between your desktop and server. Chances are you use it now and with regularity. Secure Shell is one of those tools you will eventually use during your time as an administrator.
