MDM Trouble Report for 2021 May 13

Telescope: 1.3m
Observer(s): John Thorstensen (Dartmouth)
Instrument: Modspec+echelle

Problem(s) Encountered:
For some reason Owl stopped responding to the  expose  command at
the start of the night -- I'd been power-cycling the controller,
which might have confused it? I stopped Owl to restart it, but the 
windows did not go away -- they went blank.  Then I couldn't get
input into other windows to work (though I did have the mouse).
So, I tried exiting the vnc connection.  But then I couldn't get
the VNC to reconnect!  I did still have my terminal connection.

I called Eric and he saved the situation by taking mdm13ws1 down 
to clear any connections and setting me up on mdm13ws2, which 
worked fine for the rest of the night.  ws1 has an issue right
now where it won't reboot without someone present to hit a key,
so this was the easiest way to get going. 

The telescope was open and tracking while I could not control
it.  Fortunately, the weather was ecxcellent, but I got to 
thinking that it would be good to have a text-only command to
run the closing sequence from a terminal in case of a vnc
failure.
