Some operations you might want to carry out on the nodl require you to gain root access to it.
For those unfamiliar with the term, it pretty much means gaining super user type of access to it, you have more rights. This means you can do more things but also more damage if anything goes wrong. So please keep that in mind, and as always, passwords should remain unique and private.
Open your command line interface
Then type in the following commands:
you will be asked for your password
Type it in, and don't be surprised if you can't see what you are typing, and hit enter
If you did everything right up to here, this is what you should see.
It also means you've just gained root access to your nodl.
Repeat this step anytime one of the steps in our documentation tells you to type certain commands as a root user.
