Error in UltraVNC Viewer after 1.3.6.0

[upotrebitel]

Hi!

I use UltraVNC in SC mode, starting on client side:

Code: Select all

winvnc.exe -sc_prompt -autoreconnect -connect xxx.xxx.xxx.xxx.:XXXX -run

On my machine I run:

Code: Select all

vncviewer.exe -listen XXXX

But after UltraVNC 1.3.6.0 when I start UltraVNC Viewer, it's open a hundreds windows with error for rejected connection. On UltraVNC 1.3.6.0 and earlier versions it's work fine. After a lot of experiments, I found that removing option "-sc_prompt" from command line of UltraVNC Server solves the problem and connection is estabilished with new UltraVNC Viewer 1.3.8.1.

The problem is that I have a lot of machines, that run UltraVNC Server with option "-sc_prompt" and I can't use newer UltraVNC Viewer. So, can you fix this bug in next version of UltraVNC, please?

What's the error you get?
Is the password on the Server set, or you just run without a .ini file.

If the password is the cause:
You can disable by unchecking
UltraVNC Viewer 1.3.8.1
[v] only server with password

Error is: "Your connection has been rejected".

I have "WinVNC.ini" file and file "SecureVNCPlugin64.dsm" in the same folder with "winvnc.exe".

Code: Select all

One of the first things that I do is to uncheck "[ ] only server with password" in "vncviewer.exe". My file "options.vnc" in the same folder with "vncviewer.exe" is:

The result is the same - hundreds windows with error message "Your connection has been rejected" apperas. But when I remove option "-sc_prompt" from "winvnc.exe" command line, it's work fine!

Just tried it with your ini and option.vnc file ... and have the same as you.
Some combination of options seems to trigger it.

Yes, new UltraVNC Server 1.3.9.0 work fine with UltraVNC Viewer 1.3.8.1 and my config files. Thank you very much!

But I hope that you can make new version of UltraVNC Viewer, that work with all versions of UltraVNC Server. Because I have a lot of clients, that runs older versions of UltraVNC Server and the error appears when I run on my computer new UltraVNC Viewer, after version 1.3.6.0.

Is this an all new "dev build", beyond version 1.3.8.1?

If so, it might be time to create a new area in the "Version-specific help" area.

Thanks.

[Rudi De Vos]

Code has not yet been added to development, it a separated tree used to merge UltraVNC SC with 1.3.8.1.
A lot of refactor...but indeed we already can create a UltraVNC 1.3.9 dev area for it as UltraVNC SC 2.0 and UltraVNC 1.3.9 dev have the same source.

Still want to add some buildin ssh or/and a good p2p library, something more general the the repeater.

[upotrebitel]

Excuse me, but why my third post is still not approved by a moderator?

[Rudi De Vos]

Done!

Sorry, a new UltraVNC Viewer will not fix this UltraVNC Server issue.

[upotrebitel]

OK, can I change configuration im my "options.vnc" file to aviod this UltraVNC Server issue?

[VNCHELP890]

Is there a UltraVNC 1.3.9 area yet? Not sure if it would be linked from here.
Even if an empty "placeholder", it would indicate where to look in the future.
Thanks.

[Rudi De Vos]

Found also a way to fix a UltraVNC Viewer, so it can run with the old UltraVNC Server.

[upotrebitel]

Tell me more about this way, please?

[Rudi De Vos]

Use the new UltraVNC Viewer with the old UltraVNC Server:
