Red-Hat won't accept X-Client

[Christopher Howard <choward WavecrestComputing com>]

Good Day,

I am trying desperately to have a Solaris X-Display sent to my new
Red-Hat Linux display.

The following is what I receive on my Solaris machine after attempting
to
start my X app:
------------ BEGIN --------------------------------------
$ DISPLAY=ipaddress:0.0
$ export DISPLAY
$ xapp
Xlib: connection to "ipaddress:0.0" refused by server
Xlib: Client is not authorized to connect to Server
java.lang.InternalError: Can't connect to X11 window server
            using 'ipaddress:0.0' as the value of the DISPLAY variable.
$
------------ END ----------------------------------------

This all used to work just fine with Slackware, but hey Red-Hat Rules!

I cannot find any means to tell Red-Hat to accept my Solaris display.

Thanks in advance,
howeeeee
