端口扫描器程序，实现侦测计算机端口状态、网络系统开放的端口或在网络扫描和调试的目的-Port scanner program, realize detection calculation port scanner program, realize detection computer port state, network system open port or in the network scanning and debug purpose machine port state

半开活动端口扫描器，可避免留下日志信息。-open port syn scanner

VC++ SYN高速端口扫描器源代码,这里并不是利用connect 进行三次握手探测的，而是利用SYN形式进行一次握手探测,所以速度非常的快。-VC++ SYN-port scanners source code, not here three connect handshake detection, but to use a form of SYN handshake detection, so the speed is very fast.
