Avaya Aura® Device Services resets idle SSH sessions after a certain period of time. This might affect lengthy CLI operations, such as Avaya Aura® Device Services installation or backup. If the connection with the SSH terminal is reset while installation or backup operations are in progress, you must restart these operations. To prevent this issue, you can start a Tmux session before performing a lengthy operation. Commands and processes that you run from a Tmux session continue to run even if the connection with the SSH terminal is reset. Therefore, you can re-connect to the Tmux session and complete the operation.
