sc_prompt bug?

Post by albertocastillo2001 »

Hello

I am using version 1.2.1.1 and I am attempting to use UltraVNC to do a reverse connection to a viewer in listening mode. However it seems sc_prompt is not working

Code: Select all

winvnc.exe -sc_prompt -connect 1.2.3.4
As far as I know this should prompt that prompt on the viewer which lets them to accept the connection, just like SingleClick does.
Is this a bug or am I doing something wrong?

Thanks

just tested both server and viewer are 1212, possible you forgot to add the -run

vncviewer.exe -listen
winvnc.exe -sc_prompt -connect localhost -run

It seems to work

Hello

Thanks for your answer.
Doesn't seem to work for me

Had the viewer opened on listen mode and then I tried

Code: Select all

winvnc -sc_prompt -connect localhost -run
It shows a msgbox saying that another instance of WinVNC is running. If I close all WinVNC.exe threads it works fine

Take in mind that I want the UltraVNC service to be on at the same time I have the posibility of them to initiate a reverse connection using the prompt.

However running

Code: Select all

winvnc -connect localhost
works well and initiates the connection, but no prompt is displayed.

Thanks

Then the only way is tu use
winvnc -sc_prompt -multi -connect localhost -run

You just can change the prompt behaviour on a running server.
Using multi you can start a second instance of the server

Do you start the -connect as elevated admin, latest OS systems should block it.
UAC doesn't allow messages to be send higher elevated applications.

Hello

That worked. It didn't convince me much because the first bubble that appears says "cannot connect to 127.0.0.1". I tried with another host and it shows the same message

I also added sc_exit so that instance will close itself after connection is over

Code: Select all

winvnc -sc_prompt -sc_exit -multi -connect viewservice14 -run
Is there anyway to ignore that balloon that says "cannot connect to 127.0.0.1"?

Thanks
