Client程序从stdin读取数据并通过网络发送到Server程序,Server程序在收到数据后直接再发送回Client程序,Client程序收到Server发回的数据后再从stdout输出。 三、UDP Server程序 1、编写UDP Server程序的步骤 (1)使用socket()来建立一个UDP socket,第二个参数为SOCK_DGRAM。 (2)初始化sockaddr_in结构的变量,并赋值。s...

Here comes the example of the TCP chat server. It handles multiple TCP client sessions and multicast received message from any session to all ones. Also it is possible to send admin message directly from the server. usingSystem;usingSystem.Net;usingSystem.Net.Sockets;usingSystem.Text;usingNetCore...
Use the --ip-allow parameter to specify a client IP whitelist file, then the connection will be disconnected when the user's IP is not in the file. If both --ip-deny and --ip-allow are set, then only --ip-allow will work. The format of the client IP blacklist and whitelist file...
After the connection has been set up, nc does not really care which side is being used as a `server' and which side is being used as a `client' The connection may be terminated using an EOF (`^D' ) as the -N flag was given. There is no -c or -e option in this netcat, ...
