     I need a bit more information here.  You sat SSH-ing into "my"
computer.  What computer is that?  A computer at the NRAO that can run
AIPS when you are sitting in front of it?  The aips tv=local starts
an XAS server on that computer (assuming it is a real aips computer)
with Unix sockets and then must open a display window on your computer
addressed by the $DISPLAY variable.  It appears that your computer at
Tech is refusing the connection or that the $DISPLAY variable is not
set.

In fact the message about sum-ginsburg below suggests to me that you
are trying something on machines that do not run aips at all.  At
least I do not know that name.

The failure of XAS was displayed during the installation.  I am
assuming that you were compiling AIPS locally on your machine.  I
actually now recommend that you do not do that but do a binary
installation.  To do the binary

      perl install.pl -n

where the -n does the binary instead of local compile version.

To check your XAS failure:

cd $AIPS_ROOT
source LOGIN.CSH    (or . LOGIN.SH for bash)
$CDTST
cd $YSERV/XAS
make
