Unknown authentication scheme!

[tim71]

SC is really almost perfect tool for remote support, but when it comes to get it work with MSRC plugin, then I always get the same problem: I get "Unknown authentication scheme!" - message on viewer side and nothing helps.

I thought that something maybe wrong vith my included key when using your online exe creator. I tried to create exe with other key and tried to connect again - now I got this long blablabla window, which appears when protocols are not correct or plugin is not found or something like that.

When I try to create connection without encryption, then everything works without problems...

I even thought to change my binaries on viewer side to RC194 ones but could not find them anywhere any more

With RC 195 and all newer releases it's always this "Unknown authentication scheme"-thing...

I Love this program too... its GREAT!!
I had the same problem.. used the included key, tried my own, and then finally found a note in these forums about using the updated MSRC pulgin and that solved all my problems.
Good luck

Nope - that didn't help. Used 112 and 114 plugins - _reg and _noreg versions...
Always the same reaction

Hello,

I had the same problem after I reinstallt Ultra-VNC. I tried a lot and find the solution by renaming the dsm-plugin.

In my helpdesk.txt I have the following entry:

Code: Select all

[HOST]
Verbindung herstellen (128-Bit verschlüsselt)
-plugin -connect marchert.dyndns.org:5500 -noregistry

Today I loaded the dsm-plugin again from the webpage and upacked it. Then I saw, there a two version of the plugin: MSRC4Plugin.dsm and MSRC4Plugin_NoReg.dsm.

Because I have the "-noregistry"-entry in the helpdesk.txt I copied the MSRC4Plugin_NoReg.dsm to the programdirectory of Ultra-VNC and renamed it to MSRC4Plugin.dsm. Now it`s every thing ok.

In the hope I helped somebody

Peter is correct,

I only use the noreg.dsm and really I am wondering why the other *.dsm file is still packaged with UltraVNC because a lot of new users have this same problem..

reason of 2 build of encryption plugin

the mistake for SingleClick
MSRC4plugin.dsm is hardcoded instead the correct one MSRC4plugin_noreg.dsm only usable for SingleClick because there don't read registry.
