Q: How can I get root access to my system without logging in as “root”?
A: Create a user account in the WebGUI Tab> Access > Users and make sure you check “Give full shell access to user.”. In addition, add the user to the wheel group under “additional groups”. Save and apply your changes, then use an SSH client (for example putty) to connect to your XigmaNAS machine. Login with your username and password, give the command 'su'. When you are prompted for your password, type the password which you use to login to the webGUI. Now you should have root access.
