Abstract

Examples disclosed herein relate to unwrap a message received from a remote management service in a first device and to provide the message to a second device. Examples include a first message received in a first device from a remote management service through a firewall, which is unwrapped into a second message. The second message is provided to its destination. In examples, the second message is received in the first device and unwrapped into a third message. The third message is provided to a second device.

Claims

1. A non-transitory machine-readable storage medium comprising instructions executable by a processing resource to:

receive a first message of a first protocol through a firewall from a remote management service in a first device;

unwrap the first message into a second message of a second protocol in the first device;

provide the second message to an output communication port for transmission to a destination specified in the second message, wherein the output communication port is a port through which the first device transmits messages to a local network via a network interface device;

receive the second message in an input communication port ref the first device when the destination of the second message is the input communication port of the first device;

unwrap the second message into a third message of a third protocol in the first device; and

provide the third message to the output communication port for transmission via the local network to a destination of the third message,

wherein the third message is a device management request to perform a function in a computing device.

2. The storage medium of claim 1, wherein the firewall does not permit the third protocol to pass through the firewall.

3. The storage medium of claim 1, wherein the first protocol a persistent connection protocol.

4. The storage medium of claim 1, wherein the second protocol is a respond-request protocol.

5. The storage medium of claim 3, wherein the first protocol is an Extensible Messaging and Presence Protocol.

6. A system comprising:

a message engine to receive a first message of an Extensible Messaging and Presence Protocol through a firewall from a remote management service in a first device;

an unwrap engine to unwrap the first message into a second message; and

a communication engine to provide the second message to an output communication port for transmission to a destination IP address of the second message via a local network,

wherein the unwrap engine is further to unwrap the second message into a third message of a device management protocol in response to receipt of the second message via an input communication port, and

wherein the communication engine is further to provide the third message to a second device separate from the system via the local network.

7. The system of claim 6, wherein the input communication port is a port through which the system receives messages from the local network via a network interface device.

8. The system of claim 7, wherein the input communication port is a Hypertext Transfer Protocol port.

9. The system of claim 6, wherein the device management protocol is a Simple Network Management Protocol.

10. The system of claim 7, where network interface device is a network interface card.

11. The system of claim 6, wherein communication engine is further to:

receive a device management response from the second device via the local network; and

provide the device management response to the remote management service.

12. A method for controlling a device, comprising:

receiving, in a first device connected to a local network, a first message of an Extensible Messaging and Presence Protocol from a remote management service through a firewall;

unwrapping the first message into a second message of a Hypertext Transfer Protocol (HTTP) in the first device;

providing the second message to the first device for transmission via an output communication port to a destination IP address of the second message;

receiving the second message in an input communication port of the first device when the IP address of the input communication port is the destination IP address of the second message;

unwrapping the received second message into a third message of a Simple Network Management Protocol (SNMP); and

providing the third message to the first device for transmission via the output communication port to a second device via the local network.

13. The method of claim 12, wherein the third message is a device management request to alter a setting of an imaging device.

14. The method of claim 13, further comprising:

receiving an device management response message of SNMP from the second device;

wrapping the device management response into a second device management response of HTTP; and

providing the second device management response to the remote management service through a firewall.

15. The method of claim 13, wherein the device management request is a command to enter a low power mode of the imaging device.
