Actually, reading this more closely, I think you have another problem
instead.  You have fooled the computer you are running on (xun5) into
thinking that you are sitting in front of it - presumably your
$DISPLAY variable is set via SSH to something like xun5:10.0 (which is
really xun2 but how is aips to know that).  Furthermore, you have
asked for shared memory for speed but 2 disparate computers do not
share memory, hence the failure.

This is not the mode we recommend.  Instead you should use internet
TVs and have the TV and other display programs actually run on xun2
(or xun1 or ...).  When it works, the easiest way to do this is

             aips  tv=xun2

from xun5.  This will cause xun2 to start the TV servers (assuming
that xun2 is able to run aips, i.e. that it cross mounts the
$AIPS_ROOT directory).  Sometimes this does not work.  In that case,
one starts aips on xun2 to create the TV and other servers - do not
use tv=local there since these must be Inet ones.  The start aips on
xun5 with

              aips tv=xun2 tvok

which says that the TVs are already running.  Note that the question
install.pl asks about Inet vs Unix TVs is really meaningless - both
are always installed.

If you really want to run the way you were attempting, with XASn
running on xun5 with display xun2 then you must turn off shared memory
in your .Xdefaults file and merge that file 

              xrdb -merge ~/.Xdefaults

See help xas for info on the .Xdefaults parameters.
