By default, Local Managers are configured to automatically log out an idle user after 5 minutes. To modify this timeout, use the config system timeout command.
[admin@LantronixLM]# config system timeout Current session timeout is 5 minutes. Change these? (y/n) [n]: y Timeout (5 to 120 minutes) : 120
When the idle timeout expires, the user will be presented with a message and disconnected.
[admin@LantronixLM]# You have been idle for 300 seconds, your SSH session is ending. Connection to 10.10.10.24 closed.
This setting does not change the terminal pass-through timeout, which is a separate feature handled in config settings on a port resource.
