Why can’t I accept the Flash Security Dialog on Linux
On some versions of Linux desktop when loading the BigBlueButton client, the user is unable to accept the Flash security dialog asking for permissions to access the computer’s microphone and webcam.
The solution is use the Flash security manager to add an exception for the BigBlueButton host. Doing so will no longer have Flash prompt for access to the microphone/webcam.
To add an exception, do the following.
Open the following URL in a browser Flash Security Manager settings. (This will open the security manager settings for the local Computer. http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04.html
Click on the tab with screen showing an eye (Web Privacy Settings).
Look through the list for the hostname for your BigBlueButton server.
Click ‘Always Allow’ radio button.
Now launch the BigBlueButton client. You should no longer be prompted for the Flash Security Dialog.
