Notification behaviour of the shadowing feature is configured by the system administrator. The notification mechanism can be configured in four different modes as described here.
Shadow requests are silently rejected
Shadow requests are silently accepted
Shadow requests are accepted and the user is notified
Shadow requests are interactivly accepted or rejected by the user
To configure the shadowing mode use the following command and select a value of; reject, silent, notify or ask. Details about this configuration parameter is described in /shadowing/shadowing_mode .
# sudo tl-config /shadowing/shadowing_mode=ask
The above command should be run on all ThinLinc servers in your cluster.
Only newly started session are affected by the above change.
