This read-write enumerated scalar reports and controls whether a Telnet session is connected or should be disconnected; setting it to disconnect closes the session and removes its entry from the table. Admins use the write side as a remote way to forcibly log out an active Telnet user without needing physical or console access. For example, an admin who spots an unauthorized Telnet session sets this object to disconnect(2) on that session's row to immediately terminate it.
