x11vnc | ssvnc 'ReadExact: Socket error while reading'

Question

I have a x11vnc (http://www.karlrunge.com/x11vnc/) server running.

If encryption = 0 everything is working as expected and I can connect to the server via TightVNC Viewer without any problems.

If encryption = 1 I have to use SSVNC (http://www.karlrunge.com/x11vnc/ssvnc.html) to connect to the server. The client is successfully connecting, fetching the certificate, but then it fails to connect.

The x11vnc is running inside of this Docker container: - https://hub.docker.com/r/dcflachs/veracrypt-gui/ (https://github.com/dcflachs/docker-containers/tree/master/veracrypt)

System: Windows 10 64bit

Software: ssvnc_windows_only-1.0.30.zip (http://ssvnc.sourceforge.net/dev/ssvnc_windows_only-1.0.30.zip)

Answer 1

[SSVNC] is a VNC viewer that adds encryption security to VNC connections.

While the Linux version of [SSVNC] works well, the Windows version has some issues. At the time of writing, the latest version 1.0.30 is not functional, as a connection fails with the following error:

ReadExact: Socket error while reading

However, for your convienence, an unoffical and working version is provided here:

https://github.com/jlesage/docker-baseimage-gui/raw/master/tools/ssvnc_windows_only-1.0.30-r1.zip

The only difference with the offical package is that the bundled version of stunnel has been upgraded to version 5.49, which fixes the connection problems.
