Device and method for retrieving information from a device

摘要

The present invention concerns a gateway, and a method at a gateway for retrieving information from a device without requiring any configuration and installation at the device. To this end the invention relates to a method in a gateway device comprising an interface to a first network, an interface to a second network and a local web server. The method comprises the steps intercepting a request from a first device detected on the first network to a web server located on the second network, sending a webpage located on the local web server to the device, the webpage comprising means for, when the webpage is loaded by the device, retrieving information from that device and receiving information from the device, the information being retrieved from said device by the webpage.

1. Method of operating a gateway device to provide information about a first network device attached to a first network connected to a first interface of the gateway device, to a management server attached to a second network connected to a second network interface of the gateway device, said gateway device comprising a local web server, said method comprising, at the gateway device:
detecting the presence of the first network device on the first network; retrieving a first set of information about the first network device and storing the retrieved information in a local database; setting up, after retrieving said first set of information, a rule in the gateway device to route any request from the first network device to the local web server, so that said rule changes the destination address of incoming traffic from the first network device; receiving a first request packet from said first network device located on the first network destined to a third network device attached to the second network; redirecting, in response to said first request packet, said first network device to a webpage located on the local web server of said gateway device; receiving a second request packet from said first device to provide said webpage to which it was redirected; providing said requested webpage located on said local web server to said first network device, said webpage including instructions to cause the first network device to collect information about said first network device to perform a diagnostics analysis on any network problem, when said webpage is loaded by said first network device, and to send the collected information to the gateway device; receiving said collected information sent by said first network device; modifying the rule to no longer intercept incoming traffic from the first network device, when the collected information has been received; and forwarding said collected information to the management server, either upon request of the management server or via an automatic notification from the gateway device to the management server.
