If you are not running the X Window System, the Red Hat Network Registration Client starts in text mode.

You can force the Red Hat Network Registration Client to run in text mode with the command:

      rhn_register --nox

The screens for the text mode Red Hat Network Registration Client are almost identical to the screens for the graphical Red Hat Network Registration Client. Some of the text in the text mode version is more concise due to lack of space in the interface. However, there are equal numbers of screens and fields in both versions. Thus, if you are using the text mode version, you can still follow the instructions that begin in Section A.2, “Starting the Red Hat Network Registration Client”.
