SecureVNCPlugin, deploy [Copying Keys]

Postby kammajaega » 2011-07-23 12:29

Hi,

and thanks for reading !

I'm using UltraVNC on windows XP maschines.

After upgrading from 1.0.2 to 1.0.9.6.1 I wanted to give the SecureVNCPlugin.dsm a try, which drove me mad ...

I want to generate one xxx_Server_ClientAuth.pubkey and deploy that to many maschines.

Now generating one xxx_Server_ClientAuth.pubkey on one maschine and using the xxx_Viewer_ClientAuth.pkey on a remote client works, but only on the maschine the key was generated on.
When I do a fresh install of ultraVNC on another maschine, copy the xxx_Server_ClientAuth.pubkey into the install dir (same as SecureVNCplugin path) and try to connect using the xxx_Viewer_ClientAuth.pkey I only get a VNCpassword authentication and I'm not able to use the passphrase from SecureVNCPlugin config dialog, even though the viewer tells, the traffic is encrypted.

How do I have to set up the SecureVNCPlugin correctly to us one xxx_Viewer_ClientAuth.pkey to access many UltraVNC Servers?

kind regards

SecureVNCPlugin, deployment

Postby kammajaega » 2011-07-23 12:40

Hi,

I have a question concerning the setup of the secureVNCplugin:

I want to use one

xxx_Server_ClientAuth.pubkey

and deploy that to many maschines which I want to access with one

xxx_Viewer_ClientAuth.pkey

When I copy the xxx_Server_ClientAuth.pubkey into a fresh installed UltraVNC install dir

I don't get passphrase authentication only VNC password authentication.

What is the correct way to deploy xxx_Server_ClientAuth.pubkey?

Do I have to generate it on every maschine using the secureVNCplugin dialog?

kind regards

KJ

Although the PassPhrase is configured at the SecureVNCPlugin GUI, it is in fact saved inside the "ultravnc.ini" at the statement "DSMPluginConfig="

Code: Select all
DSMPluginConfig=SecureVNC;0;0x00104001;
In the above example, the UVNC server is configured to use SecureVNCPlugin, but the passphrase is not entered. In this case, the native VNC password is used for authentication, yet the communication is encrypted with SecureVNC.


Code: Select all
DSMPluginConfig=SecureVNC;0;0x00104001;MTIzNDU2Nzg5MA==
In this example, SecureVNCPlugin is used, and a passphrase is entered (MTIzNDU2Nzg5MA== is the encrypted format of it). When connecting to this server, you need to input the passphrase.


So when deploying, you also need to copy this encrypted passphrase into the "ultravnc.ini" of those new machines.
