Information acquiring method, client device and server device

Abstract

The invention discloses an information acquiring method, a client device and a server device. The information acquiring method comprises steps of: constructing an ICMP Echo message and setting a user input command in a data region of the ICMP Echo message; sending the ICMP Echo message to a server; receiving an ICMP Reply message, corresponding to the ICMP Echo message, sent by the server; and analyzing response information, aiming at the user input command, carried in the data region of the ICMP Reply message. According to the invention, by use of an interaction mode of the Reply message and the Echo message based on the ICMP protocol, the user input command is borne to the data region of the ICMP Reply message, and after the server of a gateway analyzes the user input command, the response information of the user input command is borne to the region of the ICMP Reply message, so transmission of the response information is achieved by use of the ICMP message transmitted through the network. The invention provides a novel diagnosis mode based on the ICMP protocol, a problem of difficulty in diagnosis in cases of clamping or failure of a serial port can be solved and it is ensured that the fault diagnosis of the gateway is performed smoothly.

Description

technical field [0001] The present invention relates to the communication field, in particular to an information acquisition method, a client device and a server device. Background technique [0002] In the Internet era, the home gateway has still become the link between the home computer and various mobile terminals. However, the home gateway device is a very complex system, mainly composed of the bottom operating system and the upper application protocol. The complexity of the system will inevitably bring the complexity of fault diagnosis. [0003] During the development process of the gateway device, if the debugging operation of the gateway device fails, the developer usually diagnoses the device fault through the shell command mode. The shell command mode refers to the way of inputting instructions through the command line tool of the operating system. [0004] Specifically, the developer inputs a diagnostic command through the serial port of the gateway device in the ...
