Help with RapidMiner Server Wizard

Hello, 

I am trying to run the rapidminer-server-installer script and go through the setup wizard to plug in my DB information. When I attempt to run the script (linux) it errors out: 

[root@XXXXXXXXX bin]# ./rapidminer-server-installer
No protocol specified
Exception in thread "main" java.lang.InternalError: Can't connect to X11 window server using 'XXXXXXXXXX:0.0' as the value of the DISPLAY variable.

FYI - Before running the script I tried to set the display per my machines IP address. Could there be some network related issue blocking it or am I missing something ? 

Thank you,
