Can you actually ssh by providing the username and password? If not, then if you can access the file ensure you have an AllowUsers entry in /etc/ssh/sshd_config and also that you are allowing SSH access to the subnet at the top of that file. if you do amend the sshd_config remember to restart the SSH service.

You are missing the private key id_rsa in the machine initiating the connection to the 2nd machine.
Place it on /root/.ssh/id_rsa if doing it as root. Also do not forget that SSH is picky about rights, so you have to do:
chmod 700 /root/.ssh
chmod 600 /root/.ssh/id_rsa
On the long term, consider not working as root, and using a regular user.
