Red Hat Config Tools
A set of graphical tools that comes with Fedora and Red Hat Enterprise Linux systems can be
launched from the Administration submenu of the System menu or from the command line. Most
of the Fedora and RHEL tools that launch from the command line begin with the system-config
string (such as system-config-network).
In Fedora Core 1 and previous versions of Red Hat Linux, the GUI administrations tools
all began with redhat-, such as redhat-config-network and redhat-logviewer.
Starting with Fedora Core 2, those names have all changed to system-, resulting in names like
system-config-network and system-config-display.
These administrative tasks require root permission; if you are logged in as a regular user, you must
enter the root password before the GUI application??™s window opens. After you??™ve entered that password,
most of the system configuration tools will open without requiring you to retype the password
during this login session. Look for a yellow badge icon in the upper-right corner of the panel,
indicating that you have root authorization. Click the badge to open a pop-up window that enables
you to remove authorization.
