Root and passwordsit

Wed Jan 09, 2013 5:01 pm

Just started with rasp pi.

I am logging on with 'pi' and 'raspberry'; shutting down with 'sudo' 'halt'.

Am I using a root account by doing this? I understand it's best not to be using a root account for fear of irrevocable damage.

Should I just continue with pi and raspberry log in?

Also, I think I may have created a user account in my name in error. When in some initial confusion I attempted to create an account I've got a message that that name has already been used. Can I see somewhere what accounts exist on my pi and change or delete them if necessary?

Thanks

You're not logged in as 'root' if you login with 'pi'.
If you were, you did not have to put 'sudo' in front of the 'halt' command. Sudo gives you root permission for the command/program you start with it.
How to delete your own user:
Login as pi, and issue 'sudo userdel -r <name>' and that should fix it. But you can also change the password of the user with 'sudo usermod -p <newpassword> <username>'. (when being logged in under 'pi').
If you make a new user, and you want that one to be able to issue 'root' commands, the user should be added to the sudoers group: 'sudo adduser <username> sudo'
With 'cat /etc/passwd' you get the whole list of users of the (and there are a lot of user for all kind of services, not actual 'user' accounts).

I hope that helps you...

If you are worried you have damaged your code just re-image your SD Card and you are back to square one. ;)

I am presuming form your post you are using Raspbian Distribution on your Pi Computer.

If I want to shut down from command line, having looged in with pi /raspberry I undertake the following pressing enter after each command:

sudo su
shutdown -h now

If I have issued the startx command and working in the Graphical User Environment, I go to Menu, Accessories, Root Terminal and use the above commands.

Just type

Code: Select all

sudo set passwrd root
whilst logged in as pi and then set the root password to whatever you want. Now you can login as root and suffer the consequences if you mess up. Basically that just means re-doing the SD Card.

The RPi gives you the power to royaly screw up and get back to where you started with a re-image.

Just imagine having to reinstall Windows7 just because you set up your child as administrator and the accidentaly wasted the file system.

With the RPi you let them waste the file system ad then show them how to recover it. ;)
