UDP:

/// udp server program
#include "Poco/Net/DatagramSocket.h"
#include "Poco/Net/SocketAddress.h"
#include "Poco/Timestamp.h"
#include "Poco/DateTimeFormatter.h"
#include <iostream>

TCP:

        Poco::Net::SocketStream str(ss);

        // flush() make sure the file stream is updated with the data.
        // endl() puts a newline and then uses flush().

#include "Poco/Net/SocketAddress.h"
#include "Poco/Net/StreamSocket.h"
#include "Poco/Net/SocketStream.h"
#include "Poco/StreamCopier.h"
#include <iostream>

int main(int argc, char** argv){
    const char* ipaddr = "192.168.8.71"; // the server address.
    Poco::Net::SocketAddress sa(ipaddr, 5004); // the server port.
    Poco::Net::StreamSocket socket(sa);
    Poco::Net::SocketStream str(socket);

    // Writes all bytes readable from str into std::cout, using an internal buffer.
    Poco::StreamCopier::copyStream(str, std::cout);

    return 0;
}

编译：

g++ TcpServer.cpp -lPocoNet -g -o TcpServer
g++ TcpClient.cpp -lPocoNet -g -o TcpClient
