X-Server access is denied on host
[Fatal Error] DISPLAY variable set incorrectly: 192.168.17.1:0.0
[Resolution] Verify that your DISPLAY environment variable is set correctly, 
and that there is an X11 server on the system. If you are 
running the Oracle Installer as a different user or on a different host, 
you may need to use the xhost command to ensure that host/user 
has permission to write to your display.
