Problems solved by technology

However, since this technology does not anticipate conditions for receiving data from an external device operating as a client, when there is a potential security problem for a communication device, the conventional technology may not be able to sufficiently perform security-related processing

[0024] A-1: Structure of the system 1000

[0025] Next, a first embodiment will be described with reference to the drawings. figure 1 is a block diagram showing the structure of the system 1000 .

[0026] System 1000 includes multifunction peripherals 200A and 200B, terminal devices 10A-10C, server 300, and relay devices 30A and 30B. The multifunction peripheral 200A and the terminal device 10A are connected to the local area network LN1. The multifunction peripheral 200B and the terminal devices 10B and 10C are connected to the local area network LN2. The local area network LN1 is connected to the relay device 30A, and the local area network LN2 is connected to the relay device 30B. Both the relay devices 30A and 30B are connected to the Internet 80 via an Internet service provider (not shown). The server 300 is connected to the Internet 80 . Therefore, the multifunction peripheral 200A is connected to the terminal device 10A via the local area network LN1 , and is conne...

[0099] In the second embodiment, the configuration of the system 1000 is the same as figure 1 The configuration shown is the same. However, the setting confirmation processing according to the second embodiment is different from that of the first embodiment. Specifically, when the power of the multifunction peripheral 200A is turned on, the setting confirmation process according to the first embodiment is started (or triggered). In the second embodiment, the setting confirmation process is started (or triggered) at a timing different from that of the first embodiment. Figure 6 is a first sequence diagram of setting confirmation processing according to the second embodiment. The first sequence diagram shows the sequence of steps when the recommended configuration is being used, as described above. Figure 7 is a second sequence diagram for setting confirmation processing according to the second embodiment. The second sequence diagram shows the sequence of steps performed w...

[0127] D-1: Structure of System 2000

[0128] will refer to Figures 9 to 1 7 describes the third embodiment, in which the same parts and components are assigned the same reference numerals to avoid duplication of description. The system 2000 includes a multifunction peripheral 200A, terminal devices 10A-10C, a server 300, relay devices 30A and 30B, and a relay device 30C. The relay devices 30A-30C constitute an internal network IN including two local area networks LN11 and LN12. The internal network IN is a network constructed in a single institution such as a company network or a school network.

[0129] More specifically, the multifunction peripheral 200A and the terminal device 10A are connected to the local area network LN11. The local area network LN11 is connected to the relay device 30C through the relay device 30A. Terminal devices 10B and 10C are connected to a local area network LN12. The local area network LN12 is connected to the relay device 30C through the ...

Abstract

The invention relates to a communication apparatus. In the communication apparatus, a transmitting portion is configured to transmit to a first external apparatus, which is connected to the communication apparatus via Internet, a request to request data transmission while the communication apparatus functions as a client and the first external apparatus functions as a server. A receiving portion is configured to receive specific information as a response to the request from a second external apparatus which is connected to the communication apparatus via the Internet while the second externalapparatus functions as a client and the communication apparatus functions as a server after the transmitting portion transmits the request. An executing portion is configured to execute a specific process related to security after the receiving portion receives the specific information.

Description

technical field [0001] The present disclosure relates to a method for controlling a communication device connected to an external device via the Internet. Background technique [0002] When trying to make a web server on the Internet publicly available, there is a conventional technique for confirming the operation of the web server built in the video camera. When the user of the camera presses the "Connect" button on the camera in order to publish the web server on the Internet, the camera sends its own IP address to the application server on the Internet. In response to receiving the IP address, the application server operating as a client sends a request for specified content to the IP address. When the camera receives a request for the content, the camera operating as a web server returns the specified content to the application server. If a request for that content is not received within the specified length of time period, the camera displays an error message. [00...
