The code: struct sockaddr_in ServerAddress;
SOCKET Socket = WSASocket(AF_INET, SOCK_STREAM, IPPROTO_TCP, NULL, 0, WSA_FLAG_OVERLAPPED);
if (INVALID_SOCKET == Socket)
{ ErrorExit("WSASocket error", WSAGetLastError());
return SOCKET_ERROR;
//error }
WSAEVENT eevent = WSACreateEvent();
WSAEventSelect(Socket, eevent, FD_CONNECT);
ZeroMemory((char *) &ServerAddress, sizeof(ServerAddress));
ServerAddress.sin_family = AF_INET;
ServerAddress.sin_addr.S_un.S_addr = ulIp;
ServerAddress.sin_port = htons(nPortNo);
if (SOCKET_ERROR == WSAConnect(Socket, reinterpret_cast<const struct sockaddr *>(&ServerAddress),sizeof(ServerAddress), NULL, NULL, NULL, NULL))
{ int iErrCode = WSAGetLastError();
if(iErrCode != WSAEWOULDBLOCK)
{ closesocket(Socket);
ErrorExit("WSAConnect error", iErrCode);
return SOCKET_ERROR;
//error }
}
DWORD retCode = WSAWaitForMultipleEvents(1, &eevent, TRUE, INFINITE, FALSE);
WSANETWORKEVENTS NetworkEvents;
if((retCode != WSA_WAIT_FAILED) &&
(retCode != WSA_WAIT_TIMEOUT))
{ if(WSAEnumNetworkEvents(Socket, eevent, &NetworkEvents) == SOCKET_ERROR)
{ int iErrCode = WSAGetLastError();
}
if((NetworkEvents.lNetworkEvents &
FD_CONNECT ) == FD_CONNECT)
{ int iErrCode = WSAGetLastError();
if(iErrCode == WSAECONNREFUSED)
{ ErrorExit("Server refuse!", iErrCode);
return SOCKET_ERROR;
}
}
}
return Socket;

Hi Cybdrella, Perhaps it is occurring at the router frame or some other firewall. Have you tested a traceroute?

Hi Web performance did a comparative analysis of Apache Tomcat on linux and Windows. Which showed that under identical conditions. Tomcat can server 32% more users simultaneously on
Linux than on MS Widows. __________________________________________________
