Unix server - Windows client, connection failed - c++

Question

Is there anything more required in order to communicate a server unix process and a client windows process? After compiling both, i run server and then i run client. However, client fails at connect() with error: 10061.
client (windows application):

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);
if (ConnectSocket == INVALID_SOCKET) {
printf("socket() failed with error: %ld\n", WSAGetLastError());
WSACleanup();
return 1;
}
// The sockaddr_in structure specifies the address family,
// IP address, and port of the server to be connected to.
sockaddr_in Service;
memset(&Service, 0, sizeof(Service));
Service.sin_family = AF_INET;
Service.sin_addr.s_addr = inet_addr("127.0.0.1");
Service.sin_port = htons(27015);
// Connect to server.
iResult = connect(ConnectSocket, (SOCKADDR *) &Service, sizeof (Service));
if (iResult == SOCKET_ERROR) {
printf("connect() failed with error: %ld\n", WSAGetLastError());
iResult = closesocket(ConnectSocket);
if (iResult == SOCKET_ERROR)
printf("closesocket() failed with error: %ld\n", WSAGetLastError());
WSACleanup();
return 1;
}
// Message that has to be sent.
char message[1000];
printf("\nEnter message: ");
gets_s(message);
printf("Message you wrote is: %s\n", message);
// Send a 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);

Client is running on Windows 7, while server on Fedora 19 (VMware). The port was ok when i run client-server windows applications. Also, I have no anti-virus SW installed. Any help would be appreciated.

Answer 1

You are getting a connection refused error because the client is connecting to the client machine, not to the server machine.
In the client code, replace the address 127.0.0.1 with the server's address.
