Reproduced Ubuntu root can not be solved by SSH login problem

After installing Ubuntu Server 14.04 Today, the root password is configured

Can not even SSH login, but su root normal! Why

The original new version inside the sshd_config has a limit

#vim/etc/ssh/sshd_config

# Authentication:
Logingracetime 120
#PermitRootLogin Without-password #找到这里, annotate it
Permitrootlogin Yes #改为yes and then restart SSH
Strictmodes Yes


#service ssh Restart

#Tips: note here that/etc/init.d/ssh restart is unsuccessful in this way.
