摘要
TCP/IP协议是Internet的主要协议,包括链路层、网络层、运输层和应用层4层协议系统.网络建立连接需"三次握手"、连接建立后进行数据的传输过程,而连接的断开则需要"四次握手",在此基础上,对网络中的IP包的侦听以及包内数据进行分析,给出了根据TCP/IP协议的特点来阻断两个主机之间的TCP/IP通信的原理和方法,以及用Visual C++6.0编程实现的一些关键代码,并介绍了此技术的实际应用.
TCP/IP is an important protocol on Intemet, which is considered to be a 4 - layer system： link, network, transportation and application. The communication process of TCP/IP is carried out by an analysis of the three - way handshake, data transmission and disconnection of network. Based on this, the paper discusses the sniffer of IP package and analyzes the package contents. It also puts forward principles and methods of interrupting the TCP/IP communication, and gives the example codes of Visual C ＋＋ 6. 0, and introduces the practical application of the technology.
