I asnswered you before and there is clearly a language barrier here.
By "remotely form an X terminal", I take it to mean that you are
sitting in front of the X terminal but are logged in to some computer
by some name.

You have ordered aips to run XAS and other daemon tasks on the X
terminal with this command.  The X terminal cannot run such programs
(if you really mean a dumb X terminal rather than some older small
computer).

This says that sun32 is the value set to $SSH_CLIENT or
$SSH_CONNECTION in your environment.  Hence it tries to talk to sun32
(is that your "X terminal", computer server, or yet some other
computer?).

What does this mean?  Doe it mean that the X terminal is connected to
sun32 which is then ssh'ed into a compute server?  If so you are
really trying to confuse the situation.  The compute server will only
know about sun32.

What I told you last time and tell you again is

Make sure $DISPLAY is set correctly in your environment

Then use

aips tv=local

or ./START_AIPS tv=local

to start aips.  Then read HELP AIPS to see the other choices that this
tv= option has.  In particular, you may wish/need to chose the number
used (1-35 are possible).
