I have no idea what the source of the problem is. Mac users have
referred to a DHCP manager that allows them to assign a fixed name to
their machine so that it is recognized as that name wherever they plug
in. I do not know what your machine is called at your various
locations, you have not told me. Output of uname -n would say.
But you can run without shared memory - read the help file for XAS and
it will tell you about the .Xdefaults file and the aips options that
you may put into it. Among them is a logical that tells it not to use
shared memory. I would try that first.
