In lessson 2 we learned how to configure our system after completing the installation.  We found that many of these configuration utilities can be executed in the text and graphical mode.  This gives the system administrator and/or the user the much needed flexibility to easily maintain and configure the system.  As a review, this page is provided to assist you in remembering these valuable tools.  If you need further details concerning the commands please refer to the links in lesson 2 or use the man pages on your system.  To learn more about the scripts you'll have to go to the Red Hat website and search for an explanation or study the script itself.
