Winsock Returned Error Code 10051


WinSock functions: bind(), connect(), sendto(), socket(), FD_CONNECT See also: WSAEPROTOTYPE WSAEALREADY (10037) Operation already in progress. If you don't have the proper subnet mask, your network system may treat a local address as a remote address (so it forwards addresses on the local subnet to the router, WSAEADDRNOTAVAIL 10049 Cannot assign requested address. Try a "traceroute" to the host you were connected to. http://jactionscripters.com/socket-error/winsock-returned-error-code-10093.php

If you used a hostname, did it resolve to the correct address? See WSASYSNOTREADY for details. It would also timeout if a (FIN)ish TCP packet is not ACK'd (and even if the FIN is ACK'd, it will eventually timeout if a FIN is not returned). WSA_QOS_EPROVSPECBUF 11018 Invalid QoS provider buffer.

Socket Error 10054

The requested address is not valid in its context. This error is relevant to connect(), but not to send() or sendto() as it is in Berkeley Sockets. The WinSock implementation was unable to allocate additional memory to accommodate the function request.

  1. TCP/IP scenario: A connection will timeout if the local system doesn't receive an (ACK)nowledgement for data sent.
  2. WSAENOBUFS (10055) No buffer space available An operation on a socket or pipe was not performed because the system lacked sufficient buffer space or because a queue was full.
  3. At least one QoS reserve has arrived.
  4. WinSock description: Same as Berkeley.

For instance, this error will occur if you try to run two applications that have FTP servers that both try to accept connections on port 21 (the standard FTP port). WinSock description: Same as Berkeley. Since Windows Sockets is practically a clone of Berkeley Sockets, and the rule of thumb is "when in doubt, defer to Berkeley", we can adopt the Berkeley Software Distribution error text Socket Error 10049 The socket input parameter is not a valid socket handle (either it never was valid, it's a file handle (not a socket handle), or if it was a socket handle, it

Berkeley description: No equivalent in 4.3 BSD or compatible operating systems. Socket Error 11004 You can retry at a later time. The misconfiguration means the router believes it cannot communicate with the server, so it doesn’t attempt the connection. WinSock functions: gethostbyaddr(), gethostbyname(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort(), See also: WSAHOST_NOT_FOUND, WSANO_DATA, WSATRY_AGAIN WSASYSNOTREADY (10091) Network subsystem is unavailable Berkeley description: No equivalent.

WSA_QOS_BAD_STYLE 11012 QoS bad style. navigate to this website For instance, this error will occur if you try to run two applications that have FTP servers. An overlapped operation was canceled due to the closure of the socket, or the execution of the SIO_FLUSH command in WSAIoctl. The error can also occur in an attempt to rename a file or directory or to remove an existing directory. Socket Error 10054 Connection Reset By Peer

A blocking operation was interrupted by a call to WSACancelBlockingCall.

Check that the WINSOCK.DLL file is from the same vendor as your underlying protocol stack. This error is returned from operations on nonblocking sockets that cannot be completed immediately, for example recv when no data is queued to be read from the socket. WSAEALREADY (10037) Operation already in progress An operation was attempted on a non-blocking object that already had an operation in progress.WinSock description: WSAEALREADY means that the asynchronous operation you attempted to Socket Error 10061 Connection Refused Windows Error Code 10038 -...

a "high-level" protocol). I would suggest having the caller pass in the actual size value: BOOL CBlockingSocket::Connect(LPCSOCKADDR psa, int sasize) { ASSERT(m_hSocket != INVALID_SOCKET); // should timeout by itself if (connect(m_hSocket, psa, sasize) == It can occur if you're trying to run too many applications (of any kind) simultaneously on your machine. http://jactionscripters.com/socket-error/winsock-returned-error-code-10038.php A database query failed because it was actively refused.

Developer suggestions: for protocols and services consider using a hard-coded value for the protocol number or service port number in case your resolution attempt fails, and you can have your cake A request to send or receive data was disallowed because the socket had already been shut down in that direction with a previous shutdown call. This has no network-relevant analog (although the "inode" reference could refer to a network file system entry). Do you have the Winsock DLL that supports the version of the Winsock specification required by the application?

However, some WinSocks fail with WSAEINVAL you call connect() a second time (or subsequent) on a non-blocking socket. WinSock description: The 'address' they refer to, typically refers to the local 'socket name', which is made up of the 3-tuple: protocol, port-number and IP address.
