You need to authorize your session on soback.kornet21.net to open the
display on fredf12. To this end, I found the following url helpful.

Short answer: you could first do `xhost +soback.kornet21.net' on
fredf12. The drawback is that then anyone on soback could open your
display. Check out the "Remote X Apps--Mini How-To," url above, also
the Xsecurity(1), xauth(1) and xhost(1) man pages.
