This Windows NT Sample Network provider implements a small subsection of the NP interface. What it shows is how you can sample logon information when a logon is performed. This "credential sampling" is often useful for implementing unified logons with differing OS platforms. Once you gather the information in the NP, you can then communicate the credentials to another platform for verification and establishment of network resources.-Sample Windows NT Network provider im plements a small subsection of the NP interface .

要在相同的网络终端上绑定到不同的套接字上，所以必须为这些套接字设置SO_REUSEADDR属性（即允许重用），否则侦听会失败。 4、S的【协助打洞】连接收到A的申请后通过【主连接】通知B，并将A经过NAT-A转换后的公网IP地址和端口等信息告诉B。 5、B收到S的连接通知后首先与S的【协助打洞】端口连接，随便发送一些数据后立即断开，这样做的目的是让S能知道B经过NAT-B转换后的公网IP和端口号。 6、B尝试与A的经过NAT-A转换后的公网IP地址和端口进行connect，根据不同的路由器会有不同的结果，有些路由器在这个操作就能建立连接，大多数路由器对于不请自到的SYN请求包直接丢弃而导致connect失败，但NAT-A会纪录此次连接的源地址和端口号，为接下来真正的连接做好了准备，这就是所谓的打洞，即B向A打了一个洞，下次A就能直接连接到B刚才使用的端口号了
