Therefore, the security of network information is becoming very important. Network hosts must have adequate safety, or the value of the network would be devalued. The development of the system was to provide the users with a useful tool that analysis the network packets. The system has four main functions: capture the network packets, analysis the packet, analysis the information of packet and display packet information. To achieve the goal, I choose the system of ubuntu (Linux), libpcap. apache, mysql and php platform to develop the system. The operating systems and software development kits are free, this is one of the systems features. The system used libpcap to capture data packets firstly, and then use the C language, and TCP / IP protocol as the basis theoretical to analytic packets, the database of mysql stored the result of Analysising information. Module of packet analysis reads the information from the database of mysql, statistic and analysis the information, and then describes security conditions. Finally, use the apache and php technology to display database information. Through the test of the system to achieve the goal that capture and analysis data packet, information analysis, display information, it is a good reference for users to keep up on the current state of network. Key words: Network packets; TCP/IP; Packet analysis; Packet information analysis; Attack characteristic 目 录 论文总页数：26页 1 引言 1 1.1 课题背景 1 1.2 国内外研究现状 1 1.3 本课题研究的意义 1 1.4 本课题的理论基础 1 2 网络数据包分析系统概述 2 2.1 网络数据包分析的意
