端口扫描器 支持tcp全连接和syn扫描-Port scanner Full support for tcp connections and syn scan

本程序向网络服务器发送SYN连接包，获取网络服务器TCP、UDP端口信息，实现网络协议扫描。-The program sends packets to the network server SYN connection, access to network server TCP, UDP port information, network protocol scan.

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
