No root password?

Hi guys,

I have just created a new linode and was in the process of setting it up as per your guide.

However contrary to what the guide says, I have am not being asked for my root password once I try to ssh [email protected]

Is this normal?

Could be… Did you set a root password when you created your Linode? If not, then the behavior you're seeing is normal.

It's not a very good idea to have a Unix/Linux system without a root password. It's also not a very good idea to allow the super-user to login using an ssh(1) session. See here:

Wouldn't using SSH keys be safe to log in as root?

If root already has a password, how would you delete it (via sudo) so that only SSH Keys will work?

You write:

That's not the point… Allowing remote root logins is a YUUUUUUGGGEEE security hole. This is why God invented su(1)/sudo(1).

You don't delete passwords for anyone. You configure sshd(8) to not accept them as valid login credentials. See:
