UltraVNC

A key is optional.
Using a key, only the viewer who has the private key can connect

I see. Still, i was able to connect to a server that has a key using a viewer that had no key. Which is exactly the opposite of what you just said.

UltraVNC server x86_64 1.2.5.0 build Mar 25 2020 21:22:37 UltraVNC viewer x86_64 1.2.5.0 build Mar 25 2020 21:25:39 UltraVNC viewer i686 1.2.5.0 build Mar 25 2020 21:26:28 I've tried to use SecureVNC plugin 2.4.0.0 and 2.4.1.0 Either way, i am able to connect to the server with plugin enabled. The ...

Disabling AMD Radeon(TM) R7 Graphics device (the other is R5 M200) resumes the updates (with obvious side-effects of not having hardware-accelerated desktop).

Windows 10 x86_64, UltraVNC server 1.2.1.3 (or 1.2.1.2). After connecting with a viewer, i see the remote desktop for a couple of seconds. Then updates stop. Asking for a refresh results in a black screen being shown. Input is still sent and received in both directions (viewer can move host cursor ...

There's no "connections options" to click in SSVNC viewer. It does have a viewer options window though, available by pressing F8. Nevertheless, i didn't have anything to lose by trying to follow your advice, however unlikely it seemed at the time. So i did F8->Scale viewer->auto That screwed up the ...

When connecting SSVNC 1.0.29-2+b2 viewer (Debian x86_64) to UltraVNC 1.2.1.0 server (Windows 7 x86_64), i get display corruption, usually around mouse cursor (but sometimes in other parts of the screen). Corruption looks like small blocks of black or white pixels or thin-ish lines of black pixels ...

UltraVNC by itself has no encryption, but there are, of course, plugins that do it. Problem is, this only works when both server and client are UltraVNC. Other servers use different encryption methods. It would be desirable to be able to use UltraVNC viewer with these servers. Specifically, i'd like ...

1.2.0.8 pre-release does not fix this (in case anyone is wondering). That said, since w8hook is now built into winvnc.exe, the remove-w8-hook workaround is no longer available.

Quite possible. The laptop on which i've seen this bug is quite old (Thinkpad R500). I don't remember seeing it on Windows 8.1 that was there previously, but i wasn't looking too closely back then.

Only happens on 32-bit Windows 10. 64-bit OS (using 64-bit server) is not affected.

I could try 32-bit server on 64-bit Windows 10, if you think that'll help.

32-bit Windows 10 1.2.0.6 32-bit server, w8hook and schook are installed. When a connection is established, winvnc.exe (the child one) memory usage (private bytes) starts to increase rapidly, reaches past 1GB (the laptop on which i'm testing this only has ~3GB RAM, so it could be that 1GB is not the ...

Tested it. I can confirm that the bug is fixed in this build.

Have you thought about using something other than Visual Studio to build UltraVNC? AFAICS, UltraVNC has few external dependencies and not a lot of compile-time options, so it shouldn't be hard to come up with a non-MSVS-based buildsystem (depending on which buildsystem is used, it could still use ...

IANAL, but as far as i've read the meaning of "combined work" (which makes GPL apply to the whole work) is not restricted to linking binaries together. That is, if a GPL-covered program is, somehow, a component (even if it's launched in a separate process and intreaction is commandline and ini files ...

When should i expect the next release that would have this fix in it?

Anything else you need? I can produce stack traces, if you give me debug symbols (well, ProcessHacker's stack traces for VS debug symbols; gdb stack traces for MinGW debug symbols). Or maybe create a special version of winvnc.exe with profiling information, so that i can profile it and see where it ...

Affects i686 and x86_64 servers. Problem: winvnc.exe consumes 100% of one CPU core. Install UltraVNC 1.2.0.5 on a Windows 8.1 machine (i686 or x86_64) Install w8hook. Connect to the server with UltraVNC viewer 1.2.x.x (only tested with x86_64 viewer). Observe minimal CPU usage by the server ...

Tried it.

Special keys still work (Alt-tab definitely works; not sure which other keys you need to be tested).
Behaves better - keystrokes are processed normally.

x86 Windows 8

Anything else you need? I can produce stack traces, if you give me debug symbols (well, ProcessHacker's stack traces for VS debug symbols; gdb stack traces for MinGW debug symbols). Or maybe create a special version of winvnc.exe with added stack trace dumper, and i'll send you the logs. Or i can ...

UltraVNC 1.2.0.1 installed on an x86 Windows 8.1 machine, into C:\Program Files\UltraVNC Using x86_64 UltraVNC 1.2.0.1 viewer to connect. Also tried TightVNC Java viewer (see below for the difference it makes). w8hook is installed, schook is not. Mirror driver is not installed. Tried different ...
