Ask for help. To create a server socket, use the bind binding port problem-CodePudding

 memset (& amp; Tcpstruct, 0, sizeof (Tcpstruct)); 
Tcpstruct. Sin_family=AF_INET; 
Tcpstruct. Sin_addr. S_addr=inet_addr (IP); 
Tcpstruct. Sin_port=htons (port); 

Bind (ServerFd, (sockaddr *) & amp; Tcpstruct, sizeof (Tcpstruct));

Just started to learn, I port in the server code passed in 66, through the converted Tcpstruct. Sin_port is 16896, and then after the program is running, with netstat found not the two view port, the four basic it is 3 w w more port number, and each run is different, through a Telnet can use netstat view port connection, this is what reason, consult the bosses
