The Sessions tab provides a way to manage current connections.
If enabled, session management allows viewing of connected users and and the ability to disconnect them if needed.
The sessions tab contains a list of currently connected clients. This list consists of the connected client's IP Address, logged in Username, and the amount of time they have been connected. This tab also contains the ability to disconnect selected users from the server.
This functionality can be enabled and disabled using the Enable Sessions Management checkbox.
SSH Admin Service
When running the server as a Windows service and session management is enabled, a special SSH administration service is hosted on port 8122 (default). This is exposed as a way for the user application (UI running in the system tray) to communicate with the SSH process that is actually accepting connections. The use of this service is transparent to you as the user. You do not need to take any special steps to use this, it is handled by the application.
