VNC access with password
Hi
I have several VNC Server, some with, some without password.
For all servers without password, the connection works
For all servers with password I get a black screen or an error message that the connection was closed by the server.
If I connect to this VNC Servers with any other VNC client I’m able to connect.
Any idea what the problem could be?

Can you find out what VNC server/version is on the one that is failing, and
how it's configured (aside from requiring a password)?

Hi
The two connections where not on the same computers
As far as I know the VNC Servers are running under Windows CE, the exact version of the server is not know, but for sure it’s an older version
Reason, these are operator panels of machines I need to integrate.
Modifications and updates to these Win CE Panels is not possible

Hi Nick
Many thanks!
Unfortunatelly it’s still not working, whenever I need to provide a password, the screen is black afterwards.
The first connection on the printscreen was without a pw -> working
The second with pw -> connection ok, but black screen
Well, I'm not sure what's going on - not sure if anyone else in the community can step in and provide any insight. Could you provide details about the VNC server you're trying to connect to - what operating system, what VNC server/version, etc.?
Also, when you say first connection without pw - is that to the exact same system, just without a password? Or is that to a different VNC server?
Finally, please keep replies to the mailing list - I'm running out of ideas, here, and if you reply directly to me, then others won't be able to see the traffic and step in and suggest things to try :-).

The only thing I can think at this point is that it's related to the
following recently-closed JIRA issue:
https://issues.apache.org/jira/browse/GUACAMOLE-424
Can you try building guacd from the most recent github master and see if
the problem still exists?

Hi Nick
Version is 0.9.13
No added security on these VNC Servers, just a simple password.
Attached the syslog, other logs show nothing.
Thanks for your help!

- What version of Guacamole are you running?
- Are there any error messages in the logs, particularly in the guacd log file (usually logged to syslog, so /var/log/messages, journalctl, etc., depending on your Linux distribution)?
- Are the ones with passwords using any sort of encryption or added security?
