Just for reference, my solution is: To keep the connection alive, and for both ends to realise that the connection has been dropped:
- setServerAliveInterval (in my case set to 30 seconds) - ClientAliveInterval in sshd config on the server (in my case set to 30 seconds) And then to reconnect on a dropped connection: - Using Timer to poll the Session object every 5 seconds, checking session.isConnected(), and to connect again. I used a new Session object, as re-using the same session gave some errors on malformed packets. Thanks! Michal.
