After a while, if the client is not connected to the server, it is impossible to connect via ssh , apache and smtp do not work, that is, all services are disabled. How to make the server accessible all the time? can that correct in sshd.config ?
I physically disconnect the server from the outlet and then turn it on, everything works for a while, then access is not available. while ssh client is connected all the time everything is fine.
It is necessary to disconnect for a while, the procedure has to be performed again and all services are started: mount the hard disk and start motion-monitoring (registration).
