Help with SC and secureVNCplugin

[vtach3743]

I'm having trouble getting the secureVNCplugin working with SC. Upgraded the server side to 1.2.0.5. Built an .exe using the online tool. People have posted it works but are fuzzy on how to get it to work.

I generated the public/private key
added secureVNCplugin.dsm and the public key to the .zip file and used the creator, I also tried it with just the key file. I got something back without errors, but when I try to connect it doesn't work. Only thing that happens is that when I kill the client the server side displays an error about possibly having the wrong encryption setup.

I'm doing something wrong, any help would be appreciated.

Thanks

On the sc creation page
http://www.uvnc.com/downloads/single-cl ... loads.html

Code: Select all

The encryption plugin used by SC only exist for w32..
Download viewer+plugin.
To create encryption key, run winvnc.exe, select plugin "MSRC4Plugin_for_sc.dsm", config, create key.
Add the key as rc4.key to the zip file you upload..

http://www.uvnc.eu/sc/sc_viewer.zip

You can use viewer 1.2.0.5 win32 with the special plugin.

When you upload a zip, to create an sc
rc4.key
helpdesk.txt
icon1.ico
icon2.ico
logo.bmp
background.bmp
enter.bmp
are used, all other files ( exe dll etc..) are ignored.
winvnc.exe and plugin are added from our server.

So it's using the MSRC4 plugin and not SecureVNC? We have it working with MSRC now, but SecureVNC looks to be more secure so that's why I was interested.

We use the old plugin to keep it general.
SC was already modified to work with the new plugin, but this plugin only support certain OS's.

For the full version you have an installer that can select required files based on the OS, for a sc you need something
that works on all OS's.

Another issue is encryption export.
MSRC use the buildin MS encryption, so SC actual doesn't contain any encrytion functions.
For some company's this is an issue.

I'm a little confused (it's not hard to confuse me!). SC was modified to work with the "new" plugin. Is that SecureVNC? My uses for it are only for Win XP,7 and 8. Exporting is not an issue in my case.

[Rudi De Vos]

For now... online creators only use MSRC4 plugins.

What i wanted to say was, Technical it's possible, but not implemented for the online creators.

I've already changed the source for my wishes and I'm wondering, if it would it be a big disadvantage, if the dsmplugin would compiled into the winvnc.exe. It seems, it's not a lot of source...
Do you think it's worth trying it?

Until now I only share the one winvnc.exe, no helpdesk.txt or others and don't use the encryption-plugin. Furthermore I could not make out a difference, if vnchooks.dll and zlib.dll are present or not, so I don't use them.

Thanks for all the help here in the forum!

The reason we used plugins was export of encryption.
Some people we worked on uvnc had some trouble in the past because there software contained encryption code.
