integrity problems with plugins (Vista64, XP64)

[Harry]

Hi,
I've been struggling with the plugins for quite some time now and followed topics in here, but I couldn't figure out a solution so far (apart from using UVNC without encryption plugins).

The latest setup/phenomenon looks like this:

I installed the 1.5.0.6 x64 Update onto a Vista-64 SP1 machine (updating from 1.5.0), full installation. Trying to use a dsm plugin in the server's admin properties gives me the "The Plugin cannot be loaded. Please check its integrity." warning when clicking on "Config" when using ARC4, AESV2 and MSRC4-122. Interestingly the warning doesn't show up when using the "old" 75KB MSRC4 (the one that comes with the installation).
This means, I can only use the old 75KB MSRC4 plugin with the server 1.5.0.6 x64 on Vista-64.

But, I cannot use the viewer on another machine using that plugin.
I tried to use the "viewer only" 1.5.0.6 x64 on a XP64-SP2 machine. Trying to use any of the plugins fails with the above message, even with the "old" MSRC4 plugin (even if I copy it from one comp to the other).
Interestingly, if I use the w32 1.5.0.6 "viewer only" on this machine, it will work with all plugins (ARC4, AESV2 and MSRC4-122) _except_ with the "old" MSRC4 (which works on the x64 server on Vista-64).
I also tried to install the viewer and use the plugin that comes with the installation - same message.

Also, even though I can use the viewer binary (1.5.0.6 x64) on the Vista-64 machine and config the MSRC4 plugin: if I copy that binary to the XP64 machine along with the plugin, they stop to work together.


Basically, can anybody help me find a setup of UVNC that will work using an encryption plugin? Thanks.

When the plugins are used, a copy of the plugin is created in the UltraVNC program directory. This is bad programming practice of course, the copy could be created in %temp%, but anyway...

If you run the UltraVNC Server as a service, the above shouldn't be a problem. But if you run it as a user application (even as Admin on Vista), it will not have permission to write this copy of the plugin into the directory.

The same problem occurs for the viewer.

The minimum additional permissions you need to set on the C:\Program Files\UltraVNC program folder are:

INTERACTIVE: Create Files/Write Data : Apply to this folder only

That will allow the logged in user to create a file in that folder (but not modify any existing file or folder). The created file will be owned by the logged in user, so he will have permission to delete it again when finished.

Using a X64 version ,the plugin need to be X64
Using a X86 version, plugin need to be X86

A 32Bit plugin doesn't work on X64 and invers

Thanks for your replies.
Both issues make sense to me.

What I don't understand is, running the server as service doesn't change a thing (still the error message as above). Furthermore, the viewer is run on an XP.

Secondly, how do I check whether the plugins are 32 or 64 bit, and where would I get the 64bit version?
Interestingly, the x64 viewer will not run with the (only) plugin that CAN be used in the x64 bit server!

the developper of dsmplugin encryption is working on x64bit of msrc4 and i think for the arc4 and aesv2

And where would I find the developer version of DSM plugins?

huh?
your message probably got cut off...

I am having similar problem, but on Windows 2003 Server x64, anyone knows if there is a x64 version of the DSM plugin?

Thanks!

Same problem here except with the AESV3 plugin
