I decided to change the root password that came preset on a fresh DigitalOcean server (ubuntu 12.04).
I used the first answer to this post: How to change root password in ubuntu?
which is:
sudo -i
passwd
(set my new password on prompt)
sudo passwd -dl root
Now I can't login as root on tty1 on my server, nor can I access my server on Filezilla, etc...
What did I do wrong, and more importantly how can I recover my root login?
Thank you for your help.
The command
sudo passwd -dl root
is for disabling root and removing root password. As explained in man passwd:
-d --delete
Delete a user's password (make it empty). This is a quick way to disable a password for an account. It will set the named account passwordless.
-l --lock
Lock the password of the named account. This option disables a password by changing it to a value which matches no possible encrypted value (it adds a ´!´ at the beginning of the password).
So you just need to set root password again.
So, first execute in a terminal
sudo passwd root
or
sudo -i
passwd
you will be prompted for a new Unix password. Write it twice (second time for confirmation).
Then execute
sudo passwd -u root
to unlock the account. This should return
passwd: password expiry information changed
Now you will be able to access root. But it is not a good idea as you can see here.
