     There are 2 important parts to this line: GUESSING since it is
very hard to determine the name of your computer when you are logged
into another computer via ssh, and the blank at the end that says that
the guessing game failed entirely.  AIPS is attempting to determine
the name of the machine at which you are sitting so that it can tell
that machine to run XAS, MSGSRV etc.  You have given it no help
(although I am guessing that all you typed was "aips" since you do not
say).  Try typing
      aips tv=whereIam
where whereIam is the name of the machine at which you are sitting.
If that fails you may have to first run aips on whereIam and then on
the remote compute host say
      aips tv=whereIam tvok

If you want, you can run XAS on the compute server and set the display
to the machine where you are sitting.  Set the $DISPLAY variable
appropriately, then
       aips tv=local
This is usually too slow.

Details are in the AIPS help file, man page and CookBook.  And the XAS
help file.

Try one thing

printenv | grep SSH - I am curious what you get.  We attempt to use
certain SSH_CLIENT variables and the like to guess where you really
are.  They must not be set in your case.
