VNCviewer Bug -- No Warning when connecting to a Non-encrypt

Post by YY »

When the viewer specifies using a dsmplugin, if connecting to a server not using encryption, the viewer should pop up a warning window of "Accept insecure connection". However, this feature is broken on 1.0.9.5 and 1.0.9.6, the connection is established without this warning. Even worse, when checking the viewer's Connection Info, it reported the configured dsmplugin was being used.

Both normal and reverse connection have this problem.


Have verified with 1.0.8.2 viewer, no such bug.

Still a minor defect.

The viewer's Connection Info still showing a plugin is used, in fact not.

Technical, plugin is used even without encryption.

Message
Status: Connected (SecureVNCPlugin-v2.3.0.0)
In progress (no encryption)

Older plugins get unloaded,
SecureVNCPlugin-v2.3.0.0 stay loaded, even when not used.

This change in behaviour caused the initial error.
