Ubuntu is Debian-based distributions that don’t allow logins by the root user by default, either locally or remotely via SSH. Previous post, i have discussed how to enable root login on Ubuntu 14.04 by issue the following command :
sudo passwd root
Above command not allow the root user to remotely use SSH connection by default. There are a few more steps need to perform in order to allow root to use SSH on Ubuntu 14.04. Kindly follow below steps :
1. Login using normal user and su to root. Edit /etc/ssh/sshd_config :
ehowstuff@ubuntu14:~$ su - root Password: root@ubuntu14:~# vi /etc/ssh/sshd_config
2. Comment out #PermitRootLogin without-password, add PermitRootLogin yes into the line :
# Authentication: LoginGraceTime 120 #PermitRootLogin without-password PermitRootLogin yes StrictModes yes
3. Restart ssh service to take affect the changes :
root@ubuntu14:~# service sshd restart ssh stop/waiting ssh start/running, process 1499 root@ubuntu14:~#
4. That’s all.

No way to login as root from putty or other ssh client

June 19, 2014 at 2:57 pmUbuntu 14.04 has ssh bug, it may still failed to allow root login by simply run “service ssh restart”. But reboot the OS will make it work. Saying others dumb-ass is not polite even if you are the most smart in the universe.
