Fast track to start the Monitor routines on Utter
You notice system failure when the SCG
monitor does not update its contents any more, e.g. after a
Here is what to do:
Log in on "gs-dator" Utter (e.g. by VNC). The details for
login must be obtained from the responsible person.
Also: Check from time to time with VNC whether the computer shows a complete and live desktop (o.k., relax) or
the login-screen (tasks ahead).

Explanations for the one who wonders, why?
The opening of windows is not really critical in exactly following
the order shown above. However, the following conditions are
- The Cygwin console window (black) should not be used for
- The first xterm (opened upon . sx (which
is the command that starts the X11-system under Cygwin))
presents an inconvenient font size. Because of some parameter
settings for the next xterm, the tcsh (tc-shell)
must be started before xterm &
- The jobs that are started on Utter require additional
settings. Before they can be started the following commands must
be issued: tcsh ; source minipath
- In order to start jobs on Holt, the script called holt
opens an xterm window on Holt using
tcip-communication with secure-shell ssh. The holt script must
be called from a tcsh environment in order to obtain convenient
font style and size. The programs that are started on holt need
a tcsh-environment too. The ssh-to-holt script uses passwordless
login. Beware! Meddling with the files in $home/.ssh/ on
either side will start a nightmare!
