Unix服务器 - Windows客户端，连接失败

Question

为了与服务器的unix进程和客户端窗口进程进行通信，是否还需要其他任何东西？编译后，我运行服务器，然后运行客户端。 10061

客户端（Windows应用程序）：

#include <winsock2.h>

int wmain()

    // Initialize Winsock. 
    WSADATA wsaData; 
    int iResult = WSAStartup(MAKEWORD(2, 2), &wsaData); 
    if (iResult != NO_ERROR) { 
     printf("WSAStartup() failed with error: %d\n", iResult); 
     return 1; 
    } 

    // Create a socket for connecting to server. 
    SOCKET ConnectSocket; 
    ConnectSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);

    sockaddr_in Service; 
    memset(&Service, 0, sizeof(Service));

    Service.sin_addr.s_addr = inet_addr("127.0.0.1"); 
    Service.sin_port = htons(27015);

    char message[1000]; 

    printf("\nEnter message: "); 
    gets_s(message); 

    printf("Message you wrote is: %s\n", message);

    if (send(ConnectSocket, message, sizeof(message), 0) == SOCKET_ERROR) 
    { 
     printf("send() failed with error code: %d\n", WSAGetLastError()); 
    } 
    printf("Message successfully sent to server."); 

closesocket(ConnectSocket); 
WSACleanup(); 

while(1); 

return 0; 
} 

服务器（UNIX应用程序）：但是，客户端在连接（）失败，错误

#include <sys/socket.h>

#include <stdio.h> 
#include <stdlib.h>

int main(int argc, char *argv[]) 
{ 
    int n; 
    int listenfd = 0, connfd = 0; 
    struct sockaddr_in serv_addr; 

    char sendBuff[1025]; 

    listenfd = socket(AF_INET, SOCK_STREAM, 0); 
    memset(&serv_addr, '0', sizeof(serv_addr)); 
    memset(sendBuff, '0', sizeof(sendBuff)); 

    serv_addr.sin_family = AF_INET; 
    serv_addr.sin_addr.s_addr = htonl(INADDR_ANY); 
    serv_addr.sin_port = htons(27015); 

    bind(listenfd, (struct sockaddr*)&serv_addr, sizeof(serv_addr)); 

    listen(listenfd, 10); 

    while(1) 
    { 
     connfd = accept(listenfd, (struct sockaddr*)NULL, NULL); 

     n = read(connfd,sendBuff,255); 
     printf("Here is the message: %s\n",sendBuff); 

     close(connfd); 
     sleep(1); 
    } 
} 

客户端上运行Windows 7，而Fedora 19上的服务器（VMware）。当我运行客户端 - 服务器的Windows应用程序时，端口是好的。另外，我没有安装防病毒软件。任何帮助，将不胜感激。

由于客户端连接到客户端计算机而不是服务器计算机，因此您正在收到连接拒绝错误。

在客户端代码中，将地址127.0.0.1替换为服务器的地址。
