Debian Squeeze : SSH disable password authentication for root allow public key authentication only

Valic — December 21, 2011 — Leave a comment

On Debian Squeeze edit the sshd_config file located in /etc/ssh/ :

Change PermitRootLogin from yes/no to “without-password”:

#PermitRootLogin yes
PermitRootLogin without-password

Restart ssh daemon and try to login with root account.

Enjoy.

In Security authentification, disable password, public key, ssh
