An information processing system transmits, via a first network, connection information for a second network that is different from the first network to a plurality of terminal apparatuses; carries out communications with the terminal apparatuses via the second network based on the transmitted connection information; stores respective items of terminal identification information for the terminal apparatuses, with which the communications are carried out via the second network; determines whether the terminal apparatuses that are identified by the stored items of terminal identification information can carry out communications via the second network; and, when determining that the terminal apparatuses cannot carry out communications via the second network, carries out such control as to prevent the second network from being used to carry out communications.

Information processing system and information processing method

An information processing apparatus has a sub system that, while a main system is in power saving state, analyzes a protocol of a network communication and recovers the main system to an ordinary power mode from the power saving state, in accordance with the protocol. There is a setting unit that sets a re-transition condition which is a condition to make the main system switch to the power saving state again, depending on a kind of the network communication. Further, there is a control unit that monitors whether the re-transition condition is satisfied and switches the main system to the power saving state in response to the re-transition condition being satisfied.

Information processing apparatus, power saving control method, and storage medium

A processing unit performs a predetermined process by a remote operation from a client device. A monitoring unit monitors a first port for an unencrypted communication with the processing unit and a second port for an encrypted communication with the processing unit, denies a connection request via the first port, and accepts a connection request via the second port. When a connection request encrypted with either one of the first port and the second port specified as a forwarding destination port is received, an encrypted communication unit decrypts the connection request and transfers decrypted connection request to the monitoring unit via the forwarding destination port.
