#1497 "Error in TightVNC Viewer: Unsupported protocol: GET /shell?c"
Hi.
I use TightVNC 2.8.27 Server and Viewer on Windows (both),
and I get the following error message from time to time:
"Error in TightVNC Viewer: Unsupported protocol: GET /shell?c"
Please see the attached screenshot.
I use the viewer in Listening mode, and remote controlling a notebook with it, using the reverse connection on the notebook. (cannot use normal connection because of security policies on the notebook)
The remote connection works well, but the viewer tells this message from time to time.
Please fix it or provide a way to hide this message.
Thank you,
Fenyo
This is not a bug. This is an intrusion. Someone saw that your computer had a port open, and tried a login method that they hoped might breach your computer, and which TightVNC did not understand. The only way to stop this is to create a VPN tunnel to your machine so that the open port for TVNC is not exposed to the wider web. Otherwise you will continue to get what TVNC believes are connection attempts, and it will warn you when they fail. There is no option (that I've seen) to suppress error messages, nor would that be desirable behavior because it would break troubleshooting.
This is still going on and while it is clear it is not a TightVNC bug (at least, the port scan is not) .. the modal error popup messages are infuriating.
Is there a way to suppress the popup errors or where or how do I submit a feature request to allow for this?
What is most annoying about it - It often steals focus from whatever I am doing (even other non TightVNC programs)
The second most annoying thing about it - when the popup message is open (and even if it is not focused and is behind what I am working on in the viewer) when you do ctrl+c on the active viewer window it prioritises the error popup from behind when copying to clipboard!
While not a bug - it is still a poor user experience and I would love to see it changed to introduce the option to ignore / prevent error popups.
