This is not very helpfull. In a private LAN these security mantras become a lot less obvious. You defend the LAN, not necessarily the individual systems. To Aryen: you might want to set PermitRootLogin to 'without-password' in /etc/ssh/sshd_config. That way, password authentications for root are still disabled and only users from machines with the correct private keys are allowed.
