Interesting - same post twice lol JK!
The DSM Plugin FAQ just tells you how to know if you are or arent using the Security plugin, not how to configure it. I think they expect you to actually read the DSM Security Module home page for that help / information.
How to use the plugin -
http://home.comcast.net/%7Emsrc4plugin/ ... _docs.html
He has a very good instruction set on how to actually download, configure and use it.
But basic instructions -
Copy - MSRC4Plugin.dsm to your UltraVNC directory (usually C:\program files\UltraVnc\ )
Server Admin Properties or Default Properties - Select DSM Plugin - click Configure.
On the dialogue box that opens click before you click Genereate Key - select encryption and select the name that you wish to use. (very last line)
By default the plugin name stays in the UltraVNC dir if you only change the name. And The encryption is the lowest. So customize it then hit the Gen Key button.
It doesnt tell you anything however if you did it right it is in your VNC directory under the name you specified.
Change the name in the server line if you customized it. Otherwise leave it alone.
****Your server is now set up to use the DSM plugin and any viewer connecting needs the Key file you just created.*** Of course if you configured it properly.
Copy the MSRC4Plugin.dsm & RC4.key file to the viewers computer under the UltraVNC dir. (Should be same as above)
When using the viewer you must select the DSM plugin, click the checkbox to use the plugin then click configure. This is where you specify the Key file. That key file can be one of many if you connect to other networks / computers.
When connecting you then use the FAQ you read to ensure you are actually using the security plugin - the easiest one is - check the top bar and it says you are or arent using the security e.g. it says + MSRC4 Plugin V.1.1.0.
Hope this helps.
~Disclaimer - if you didnt configure it right it wont work and if you arent using it properly its not my fault, the fault of the devs, or anyone else besides you..
