httptunnel-1.4.0

实现内容过滤，也是用socket发送http的绝好例子。数据通过AES和RC4加密，所以也是加密算法的很好例子。(The realization of content filtering, is also a socket used to send an excellent example of http. Data through AES and RC4 encryption, there is also a good example of encryption algorithm.)

使用VC6.0实现的TCP客户端程序。知识要点，TCP的消息机制。自定义的消息发送方法

此段JAVA程序的功能是利用SOCKET编程实现两太计算机之间的通信(This JAVA program)

局域网，聊天程序。一个基于局域网的聊天程序-LAN, chat program. A LAN-based chat program

取本机IP路由表源码例程，程序调用API函数取本机IP路由表。(Take the local IP routing table source code routines , the program calls API function takes the local IP routing table .)

扫描整个局域网ip的源代码，编译可以通过，可以使用。-LAN ip scan the entire source code, the compiler can pass, can be used.

用vc6实现的端口扫描程序，利用多线程实现的，可以选择固定的端口范围是否可用！- Port scanning procedure realizes which with vc6, use multithreading realization, may choose the fixed port scope whether can use!
