Embodiment Construction

[0057] A method embodiment of converting the TCP network communication server to a client, see figure 1 , comprising a forwarding server module 1, a server agent 2 and a client machine 3, the steps of the method include:

[0058] At least one forwarding server module providing data forwarding is set up in the TCP network. The forwarding server module is provided with a TCP network IP address, a command port 1-1 and a data port 1-2, a data transponder and a The user authentication submodule, the forwarding server module always listens to the command port and the data port, and is ready to receive the connection initiated by the server agent and the client machine, and the client machine includes the client agent and the client;

[0059] There is at least one intranet server agent to establish a connection with the forwarding server module through the command port and the data port, and the intranet server agent is at least connected to the actual service of an intranet server 4...

Abstract

The invention relates to a method for converting a transmission control protocol (TCP) network communication server into a client. The method comprises the following steps of: establishing a forwarding server providing data forwarding in a TCP network, and establishing connection between at least one internal network server machine and the forwarding server through a command port and a data port;establishing connection between at least one external network client machine and the forwarding server through the command port and the data port; and setting the internet protocol (IP) address of the TCP network, the command port and the data port in the forwarding server, wherein the forwarding server monitors the command port and the data port all the time. The forwarding server is used for service registry, service query, communication relay and the like; the internal network server machine does not directly expose services for an external network, so the security of the internal network is improved, fixed IP configuration is not needed, and precious resource of fixed IP is reduced; and because the method is a TCP communication forwarding-based general realization method, the conventional server software and client software do not need modifying, and the conventional software assets can be fully utilized.

Description

technical field [0001] The present invention is applied to the field of computer network communication, and particularly relates to a method for converting a TCP network communication server into a client. The method adopts a public forwarding server module to realize communication forwarding between an external network client and an internal network server. The server machine does not need to be configured with a fixed IP, nor does it need to modify the existing server and client software, so that the external network machine can access the services on the internal network machine. Background technique [0002] In the internal network of the enterprise, in order to ensure network security, a firewall is set up, and only the internal network machine is allowed to be used as the client to connect to the server machine of the external network, and the internal network machine is not allowed to be used as the server to allow the external network machine to connect. For example,...
