Logging in as ROOT:
> Open your SSH client, in our case we’ll use PuTTY.
> Enter your VPS’s IP as Host Name.
> The default port should be 22.
> Then, simply click Open.
> You’ll see a warning screen, where you need to click “Yes” to confirm your access.
> Now, the terminal window will open and you’ll see “login as:”, then simply enter “root” and hit Enter.
> Then you’ll see “root@*hostname* password:”. Enter your root’s password. (Note: for security reasons, the password will not be visible when you are entering it)
> Then you should see “root@*VPS username* [~]#” and voila! You are now connected!
