Research And Implementation Of Network Packet Sniffing System Based On The OS Linux

As information-based degree being higher and higher, the importance of the information safety causes more extensive attention gradually. Permeate technology to develop constantly at present. Penetrating technology to develop constantly at present, various kinds of new attack means and tools change with each passing day. This paper is just under the background, carry on relevant research and discussion to the one of the present and main penetrating technology—Network Packet Sniffing technology.It is very important for the maintenance and security of computer network to research computer network packet sniffing. Network packet sniffing system can help to diagnose Routers and other settings in network. It also monitors the traffic of network. All above can help system administrator to administer and maintain network system.First the paper reviews the development of network packet sniffing system and describes the significance of the investigation of network packet sniffing system. Then in this paper, we analyze the technology of packet sniffing, including TCP/IP protocol, data encapsulation and the...
