大学时用visual c++写的端口扫描程序，使用tcp/fin/syn进行端口扫描。-University with visual c write port scanning procedures, use tcp / fin / syn port scan conducted.

TCP SYN端口扫面源代码，C++编写，可以直接运行。-TCP SYN port scanning source code, C++ prepared, can be directly run.

SYN扫描远程主机开放的tcp端口 使用winpcap开发(SYN scanning remote host open tcp port use winpcap Development)

端口扫描能够用来查找目标主机已开放的端口，包括TCP和UDP端口。当前针对TCP端口的扫描技术有三种，分别为：全连接扫描，SYN扫描和FIN扫描。针对UDP端口的扫描技术一般是采用ICMP报文中端口不可达的信息来识别UDP端口是否开放。(Port scans can be used to find ports that have been opened by the target host, including TCP and UDP ports. There are three kinds o
