此程序可以扫描多的IP和端口。另外可以多线程训话扫描，非两种方式:connect和syn扫描-This program can scan IP and port number. In addition to lecture scanning multi-threaded, non-in two ways: connect and syn scan

VC++写的实现多线程端口扫描完整源码,不错()

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
