对即时通监听技术及其实现方案进行了较为深入的研究,解决了实现监听的两个主要问题,即时通软件文本协议格式的识别和网络数据包的截获技术;最后提出了基于Linux系统平台上的Libpcap函数库的即时通信息监听软件的设计方案和实现策略。
Studies the technology of instant messenger message monitor and its implementation.Two major problems in the implementation of message monitoring are solved. One is the identification of text message protocol of instant messenger software. The other is the technology of capturing network datagram. Finally, the design and implementation strategy of instant messenger message monitor software is brought forward on the foundation of Libpacp functions in Linux.
