端口扫描器。 本扫描器实现了：TCP Connect 扫描，TCP SYN扫描，TCP Fin扫描，TCP ACK扫描及UDP端口扫描,这些扫描能够实现扫描特定IP地址范围内端口和扫描某IP地址范围内全部主机特定端口两种模式，并且SYN扫描能够区分端口开放、端口关闭和被防火墙过滤三种状态。(Port scanner. The scanner realized: TCP Connect Scan, TCP SYN Scan, TCP Fin Scan, TCP ACK scan and UDP port scan, the scan can scan a specific IP address range of ports and scanning a range of IP addresses all host two specific ports mode, and can distinguish SYN scan open ports, port closed and the three states firewall filters.)
