I am somewhat embarassed to admit that I just fixed the "broken VNC" problem
by clicking the "enable remote connections" checkbox in the RFBServer. Apparently
I accidentally left it disabled the last time I restarted the image.
VNC access to the squeaksource.com image works again, as explained in
dan.box.squeak.org:/srv/squeaksourcecom/README. Log in to dan.box.squeak.org,
send SIGUSR2 to the VM process, then connect from your VNC localhost:1 connection
within 60 seconds of the SIGUSR2 (after setting up the port forwarding to dan).
Use the VNC password that is mentioned in the README.
This is probably way too many layers of security now that we have the port
forwarding set up on Rackspace, so maybe I should get rid of that requirement
to send a SIGUSR2 to enable RFBServer. Leaving VNC running all the time would
probably be fine. But maybe later, I will not change it now.
