用C语言编写，分别攻击了Warftp和ccproxy两个漏洞（这两个漏洞只在windows xp sp2中存在，sp3和win7已经修复。因此需要安装一个sp2的虚拟机），攻击完成后，会弹出一个攻击成功的对话框，程序比较基础，但是能够帮助初学者深刻了解缓冲区溢出的原理。(Using C language, were attacked Warftp and ccproxy two vulnerabilities (both vulnerability only exists in windows xp sp2, sp3 and win7 has been repaired, so you need to install a virtual machine sp2), and after the attack is completed, it will pop up a successful attack dialog program basis for comparison, but a deep understanding of the principles that can help beginners buffer overflow.)

该程序是telnet的Client,实现比较简陋。登录到任何bbs做测试。(-This is a telnet Client program. You can login to any bbs to test it.)

详细模拟了pop3协议的原理和实现，对pop3进行了较深入的分析(Detailed simulation of the pop3 protocol and the realization of the principle of pop3 conducted more in-depth analysis)

说明：  FTP的客户端，界面化的ftp操作，运行此程序后，需要只能ftp服务器端的用户名和密码，并且需要服务器端开启才可以进行正常的ftp下载。(FTP client, the interface of the ftp operation.)
