How to Enable Root SSH Login In Ubuntu 14.04
By Default ssh root login disabled in Ubuntu 14.04. This wasn't a case in Ubuntu 12 which had root SSH Login enabled out of the box. First time I Installed Ubuntu 14.04 and when ssh to my new server with the root user, I got the error messages Access denied.
First my thought was that I am entering the Password incorrectly and I even reset the root password. But Only after looking at the sshd_conf file, I realize that This is Because the root login has been disabled by default in Ubuntu 14. And, I did the following steps to enable Ubuntu root ssh login.
Open Ubuntu SSH Configuration File
To enable root ssh login we need to edit ssh main configuration file. Open the main ssh config file using a text editor. I always use command line text editor vim
sudo vim /etc/ssh/sshd_config
Set PermitRootLogin to be yes
And then find the Parameter PermitRootLogin. by default its value is without-password. Change value to yes, as bellow.
Now Save The Changes and restart the ssh services
Restart the ssh service
sudo service ssh restart
That would be all you need to do and You should now be able to Connect to Your Ubuntu Server Remotely using the root user login.
