Only certain machines will be allowed to access glishd so that the
GO-IARDS interaction will occur. The machines for which this is allowed
can be found via the following Linux prompt:
ls /home/aips++/stable/keys/hosts/
If a machine is present in this listing then it can support the GO-IARDS
communication. The GO session and the IARDS session will both have
to be running on machines in this list for the real-time display to work
properly.
