windows和linux之间能用socket套接字实现传输吗？

请问，客户端程序在windows下用MFC写的，服务端在linux下写的，服务端和客户端之间可以用SOCKET连接吗？
我的程序，通讯连接不起来，客户端程序：

char  buf[255];

	memset(buf,0,255);

	WSADATA              wsaData;  

	SOCKET               s;  

	SOCKADDR_IN          ServerAddr;  

	int                  Port = 20000;      //初始化Windows Socket 2.2  

	if(WSAStartup(MAKEWORD(2,2), &wsaData)!=0)

	{

		AfxMessageBox("套接字第一部就不对");

		return -1;

	}

	// 创建一个新的Socket来连接服务器     

	s = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);   

	// 填写客户端地址信息   // 端口为2000  

	// 服务器IP地址为"192.168.1.16"，注意使用inet_addr将IP地址转换为网络格式   

	ServerAddr.sin_family = AF_INET;    

	ServerAddr.sin_port = htons(Port);     

	ServerAddr.sin_addr.s_addr = inet_addr("192.168.1.16"); 

	memset(ServerAddr.sin_zero,0x00,8);



	// 向服务器发出连接请求  

	int n = connect(s, (SOCKADDR *) &ServerAddr, sizeof(ServerAddr)); 

	if (n == SOCKET_ERROR)

	{

		AfxMessageBox("建立不了连接");

	}

	// 新的连接建立后，就可以互相通信了，在这个简单的例子中，我们直接关闭连接，  

	int nlength = recv(s,buf,255,0);

	 CString strMessage(buf);

	 AfxMessageBox(strMessage);

	// 并关闭监听Socket，然后退出应用程序     

	closesocket(s);    // 释放Windows Socket DLL的相关资源   

	WSACleanup();

		close(clifd);           







	} // exit 



	close(servfd);



	return   0 ;
