Problems solved by technology

[0004] Existing IP address configuration method is mainly based on the dragging method at present, for example adopts the IP address configuration method of DHCP; Although this method can dynamically configure an IP address for the remote device, its process depends too much on the configuration of the server, and in The IP address of the remote device may change after restarting, which cannot meet the needs of real-time control in some occasions

Embodiment 1

[0045] like figure 2 It is a flow chart of the implementation of configuring an IP address for a remote device in Embodiment 1 of the present invention, and this embodiment includes the following steps:

[0046] Step 201: The server establishes a static ARP entry, and binds the IP address pushed to the remote device (that is, the IP address configured by the server for the remote device) with the MAC address of the remote device.

[0047] Step 202: The server sends an IP push message to the IP address pushed to the remote device based on a specified port, and the information of the specified port is separately stored by the server and the remote device in advance. In this embodiment, the IP push message is encapsulated by using the TELNET protocol, which is called a TELNET message. In other embodiments of the present invention, the IP push message may also be encapsulated by other protocols, such as FTP, TFTP, or other self-defined protocols.

[0048]Step 203: The remote de...

Embodiment 2

[0053] like image 3 It is a flow chart of the implementation of configuring an IP address for a remote device in Embodiment 2 of the present invention, and this embodiment includes the following steps:

[0054] Steps 301 to 303 are the same as steps 201 to 203 in the first embodiment, and are not repeated here.

[0055] Step 304: The remote device judges whether the destination MAC address of the TELNET packet is the same as the local MAC address, and if they are the same, execute step 305; if they are different, execute other packet processing procedures.

[0056] Step 305: When the protocol pre-stored by the remote device is the same as the protocol that encapsulates the TELNET message, the remote device determines whether the sending port of the TELNET message is the same as the designated port pre-saved in the local machine, and if it is the same, execute the steps 306; if different, perform step 307.

[0057] Step 306: The remote device judges whether the destination I...

Abstract

The present invention proposes a method and system for configuring an IP address for a remote device, wherein the method includes: the server establishes and saves an address resolution protocol ARP entry, and the ARP entry includes the MAC address of the remote device and the server's IP address for the remote device. The corresponding relationship of the IP address configured by the device; the server sends an IP push message to the remote device according to the ARP entry, and the destination IP address of the IP push message is the IP address configured by the server for the remote device; The remote device receives the IP push message, and sets the local IP address as the IP address configured by the server for the remote device. The invention can proactively configure the IP address for the remote equipment, and has stronger real-time performance and reliability.

Description

technical field [0001] The invention relates to the technical field of computer remote control, in particular to a method and system for configuring an IP address for a remote device. Background technique [0002] At present, methods for remote control of remote devices usually include simple network management protocol (SNMP), hypertext transfer protocol (HTTP), terminal network (TELNET) protocol and other network management means. When the server remotely manages the remote device through these means, it must know the IP address of the remote device in advance; once the IP address is lost or accidentally tampered with, the remote device cannot be controlled. [0003] In addition, many devices are not configured with IP addresses when they are first deployed after leaving the factory. Some devices will carry a default IP address after leaving the factory, but even so, the server will be limited by many conditions when it first manages and deploys the remote device. For ex...
