VncViewer version for SC?

Post by Mark Cranness »

(Why is this so hard?!)

What version(s) of the viewer and version(s) of the encryption plugin work with UVnc SC?

A long time ago I setup UVnc SC and thought I was clever to navigate through all of the confusion, and it worked perfectly.
Then I stopped using it.

Later, I upgraded my viewer app from 1.00 to 1.02, and also the dsmplugin to 1.2.0 (in response to an exploit vuln. I think).

Now I find the SC server (created with http://sc.uvnc.com/cgi-bin/upload2.pl - 1.00) does not work with the 1.02 viewer (the server says it connects, but the viewer just hangs).

No problem! I'll just nip into sourceforge and download the 1.00 viewer!
Does not work. Hangs.
No problem, I'll just download the dsm plugin from the !
Does not work. Hangs.

The dsm plugin was from here: http://ftp.erm.tu-cottbus.de/ultravnc/D ... Plugin.dsm (linked to from here: http://uvnc.com/addons/singleclick.html and here: http://uvnc.com/pchelpware/encrypt/index.html), and is version 1.1.0.0

Finally, I capture the SC program while in action, and grab the files it unpacks into the temp folder and grab the dsm plugin.
Version 1.1.6 (IIRC), and all works.

What versions of the viewer and plugin are supposed to work?
If 1.0.0, how is a new user supposed to get the right version?

Ta,
Mark

The answer was: [topic=9270][/topic]
"Include the dsm plugin you want in the custom.zip file uploaded."

I renamed the current 1.2.2 *_NoReg plugin to MSRC4Plugin.dsm and it worked OK.

The instructions should be updated to make this clear.
