Abstract
Scanning technique of port is a Synthetic technique which involves information security, information science, and computer technology .This system is build on the WINDOWS operate system. It has the Ping and scan modules .It can probe into whether a target host is opening and Probe into the port information of the target host, and obtain the information with whether a port is opening. The full text explain in detail with principle of the TCP connection, principle of the WINSOCK, the basic principle of the port scan and the scan method .When implementing, it combine the thought of the face to object, use the typical method which is the TCP connect .Through the realization of this procedure, the user can scan the port with a target host, and obtain information.
