Very good.

Yes, that is for the little used port-knocking feature (you can delete
it if it causes a persistant annoyance.)  AV software tends to have a
knee-jerk reaction to netcat because it is often in a rootkit.  OTOH on
Unix netcat/nc is often installed by default (and so SSVNC uses the
system one there.)  I don't feel like writing C program for Windows to
do what I need from netcat.exe only to avoid the AV triggers.

Could you show me (via this thread or private email) the ssvncviewer
console window printout for when this happens?  I might spot a problem.
Please include all of the output from the very beginning.

(BTW, if you don't know how to scroll or select all of the text in xterm
feel free to ask me.)

I've seen things like this.

Yes.  In a SSVNC Windows bundle look for an the the stunnel example
provided in:

	Windows/util/stunnel-server.conf

You run stunnel.exe on that conf file (modified to your needs), and
the traffic goes thru stunnel.
