Embodiment Construction

[0048] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0049] like figure 1 Shown embodiment is a kind of general transparent agent method, comprises IGB network card driver module (1), data receiving and sending module, Freebsd protocol stack (2) and asynchronous network frame module (3); Comprise the steps:

[0050] Step 100, connect the client and the server through the Linux machine, start the Linux system, and automatically run the automation script;

[0051] like figure 2 As shown, at first the Linux machine is plugged with two network cables, one is to the client (4), and the other is to the server (5), after starting the machine, enter the Linux operating system, through the transparent proxy server (6) and the network ( 7) Connect the server and the client, and automatically run the automation script. The script includes the insertion of the IGB network card driver module, the configuration o...

Abstract

The invention discloses a universal transparent proxy method. The method comprises the following steps: connecting a client and a server through a Linux machine; configuring a user script file, and starting a transparent proxy service; and the data receiving and sending module receives the data packet, modifies the data packet, then uploads the data packet to a Freebsd protocol stack for processing, and finally uploads the data packet to an asynchronous network framework module to enter a user layer for user layer data processing. The method has the following beneficial effects that the Freebsd protocol stack is used for processing data, so that the efficiency is improved, the deployment is simple, and the development is convenient; on the basis of a Freebsd protocol stack, an asynchronousnetwork development interface library Libnet and an asynchronous network development interface library LibProxy are provided; and the LibProxy is used for encapsulating the Libnet and handing over the complex situation of the network to the Libnet for processing, so that the secondary development of developers is facilitated.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a general transparent proxy method with simple configuration, convenient deployment and convenient secondary development. Background technique [0002] The traditional transparent proxy method needs to configure firewall rules such as iptables, build bridges, and control user programs. It is very dependent on the network environment. If the network environment changes later, it needs to be re-deployed. It is very inconvenient to implement and requires a detailed understanding of the on-site network topology. Environment; need to obtain relevant information according to the on-site network topology environment, such as Vlanid, etc.; need to configure the Vlan number and do bond binding; does not support multi-Vlan network and load balancing multiple line nodes; later maintenance costs are high. Contents of the invention [0003] In order to overcome the disadvantag...
