SC with DSMPlugin prompts for password (and two other quirks

Post by ontimetransport »

SORRY for the double post.

I'm stumped. I used the DSM Plugin to create an encrypted VNC connection. After I connect I am being prompted for a password. What password is it looking for?

I am running the VNC viewer in listen mode on my PC and running the SC program from the same computer. Without encryption I connect and VNC opens a million windows and I terminate it (easiest way for me to test right now.) When encyrption is on I am prompted with a password box (as if I've connected). I just ignore it and try to logon . . . nothing happens. Then when I right click on SC to close it I get this error message:

Connection Failed: Error reading protocol version.
Possible Causes: You've forgotten to select a DSMPlugin and the server uses a DSMplugin.

Hope this little bit of additional info helps (I've been editing).

Speaking of which - I figured out my logo issue so I removed that part of the post.

Yet another edit - I recompiled using WinRAR. No issue with my icons anymore. Now back to my original issue with the password. Anyone?


Thanks

Po

cause:
you miss the rc4.key
SC must have rc4.key for success connection with msrc4plugin.dsm

edit----------
no password should be inquired anyway except if forgot rc4.key and always fail as you was seen.
-----------------

reverse connection could not authenticate, and authentication matching done with the rc4.key.
