RealmConfig is a configuration utility written by Jeremy Katz and Jack Neely to make configuring the NCSU compatibility bits of the system more user friendly and straightforward.

To start RealmConfig, simply log in to the system as root and run realmconfig. If you are using X and have the Gnome packages installed you will see a graphical interface. At the console RealmConfig will use a text interface that makes use of the tab and arrow keys to navigate and the space bar and enter to select. The realmconfig executable has online help within the various utilities if you have any questions about what a particular utility does.
