You don’t need to be a Network Administrator nor a Domain Administrator to run Fing.
An administrative user account is required to install and run the software; this is a security restriction enforced on every operating system to make sure the network is appropriately protected.
If you are unsure about the type of user account you are using on a machine, please refer to the list below.
On Windows, you must be logged as a User having Local Administrator privileges. If you are unsure of your user type, click on:
Start | Settings | Control Panel | User accounts.
A dialog will pop-up and you shall see the account’s type (Standard or Administrator).
You shall be listed as ‘Administrator’.
To run the software, a Command-line tool cmd.exe shall be executed as a User Administrator.
On OS X, you must be logged as a User having Administrator privileges.
If you are unsure of your user type, click on your User Name in the menu-bar and select “Account Preferences…”. A dialog will prompt a list of all users and types (Standard, Admin, System).
You shall be listed as either ‘Admin’ or ‘System’.
You must be logged as the root user. Other equally-powerful accounts and the installation through sudo command are correct, too.
N.B. Find more about privileged access here.
You already have root permission inside the docker. You must have the permission to start docker instances on the host system.
