Setting up SSH keys for authentication without passwords

1. Log into machine ONE
2. Issue command: ssh-keygen –t rsa
3. Change into ~/.ssh directory
4. Copy contents of file id_rsa.pub from machine ONE to file ~/.ssh/authorized_keys on machine TWO. Note, if this file already exists, simply add a new line to the bottom of it. Furthermore, make sure that the key being copied is all on one line.
5. Change permissions of ~/.ssh/authorized_keys on machine TWO to 700
6. Now, you are able to log in from machine TWO to machine ONE without a password
