By default the root ssh login to Ubuntu 14.04 Linux server is disable. This is a security feature and even though you change the root password the root ssh login will be denied showing message similar to the one below:
$ ssh root@1.1.1.1
root@1.1.1.1's password:
Permission denied, please try again.
root@1.1.1.1's password:
Permission denied, please try again.
root@1.1.1.1's password:
Permission denied (publickey,password).
In order to allow a root SSH login on Ubuntu 14.04 Linux server/desktop the sshd daemon's config file /etc/ssh/sshd_config needs to be changed.
Open /etc/ssh/sshd_config and make a following changes to the line specified below:
FROM:
PermitRootLogin without-password
TO:
PermitRootLogin yes
Once you have made the change, restart the SSHD service for those changes to take affect
# service ssh restart
Once done you can successfully SSH login to ubuntu server
$ ssh root@1.1.1.1
root@1.1.1.1's password:
Permission denied, please try again.
root@1.1.1.1's password:
Permission denied, please try again.
root@1.1.1.1's password:
Permission denied (publickey,password).
Open /etc/ssh/sshd_config and make a following changes to the line specified below:
FROM:
PermitRootLogin without-password
TO:
PermitRootLogin yes
Once you have made the change, restart the SSHD service for those changes to take affect
# service ssh restart
Once done you can successfully SSH login to ubuntu server
