Passwordless root SSH Public Key Authentication on CentOS 6

Need to remote login to linux servers?

Create a public key and store it in the remote server. By default it is recognised as authorized_keys but this is fully configurable. The ssh-keygen generated the public key with RSA that is by default called id_rsa.pub

A well written article to do this can be found at Passwordless root SSH Public Key Authentication on CentOS 6

An alternative sshpass command as mentioned in January 31, 2014 Linuxpromagazine seems to force users to make the password visible. Good that this is no available in a default Centos 6, as this will help to maintain good password practices. I.e. do not have password kept where anyone can read it.
