Ssh login без парола

vi /etc/ssh/sshd_config

   #LoginGraceTime 2m
   #PermitRootLogin no
   #StrictModes yes
   #MaxAuthTries 6

Make the line look like this to disable logging in through ssh as root.

   PermitRootLogin no

Now you’ll need to restart the sshd service:

   /etc/init.d/sshd restart
