SC - encryption doesn't work

[kuriharu]

I'm running VNC viewer in listening mode, and I've added the "-dsmplugin MSRC4Plugin.dsm" to the shortcut. I have installed MSRC4Plugin.dsm in the UltraVNC directory, generated a new rc4.key file, added that to my zip file and built it. When I run my .exe on the remote PC , it says I'm connected, but VNC Viewer gives me an error "WriteExact: DSMPlugin-restorebuffer alloc error", and vnc viewer crashes.

If I run it without the plugin, it works fine. I DO need encryption as this will be working in a hospital. Anybody have any clues? I've been doing this over and over all afternoon.

Hello Kuriharo,

You are right.
There is an incompattibility between dsm plugin versions.

You should open you uvnc sc executable with 7-zip, and take the dsm plugin you find in here for you viewer as well.
So extract the dsm plugin to your uvnc program directory.
Then add following to your viewer menu-shortcut for the "listen"modus:
C:\Program Files\UltraVNC\vncviewer.exe -listen -dsmplugin MSRC4Plugin.dsm

This way, you will be using the same dsm plugin both at the viewer as on the server side.
Now it will work.

Whish you much fun....

Hello Kuriharu,

I forgot a small detail.

You will need to put the generated rc4.key (same as you used for generating the sc server) file in your uvnc program directory too (C:\Program Files\UltraVNC\)
Then you need to run uvnc viewer and check if the plugin can find the key file. (if all paths are set correctly (graphical interface, no worry)

Have much fun.
