If the hostname resolution uses a local hosttable, it's possible you resolved to an old obsolete address. Developer suggestions: If you have a network analyzer available, you can quickly check if the destination port number and host address are what you expect. WSATRY_AGAIN 11002 Nonauthoritative host not found. User suggestions: Things an application user can do to diagnose the error condition further, and/or remedy it. Source

Return code/valueDescription WSA_INVALID_HANDLE 6 Specified event object handle is invalid. SO_ACCEPTCONN, SO_DONTLINGER, SO_KEEPALIVE, SO_LINGER, SO_OOBINLINE and TCP_NODELAY are not supported on sockets of type SOCK_DGRAM. recv() & recvfrom(): socket not bound (for Dgram) or not yet connected (for Stream), or the requested length is zero (whether a length >32K is acceptable as a non-negative value is WSA_QOS_RESERVED_PETYPE 11031 Reserved policy QoS element type. https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx

Socket Error Codes Linux

This is usually a temporary error during host name resolution and means that the local server did not receive a response from an authoritative server. WSA_IO_PENDING 997 Overlapped operations will complete later. Returned by WSARecv and WSARecvFrom to indicate that the remote party has initiated a graceful shutdown sequence. WinSock description: No error.

  1. An MX record is returned but no A record—indicating the host itself exists, but is not directly reachable.
  2. User suggestions: Check your WinSock, protocol stack, network driver and network interface card configuration.
  3. Check your WinSock implementation documentation to be sure all necessary components are currently installed and configured correctly.
  4. The values for WSANO_DATA and WSANO_ADDRESS (11004) are duplicates, so we don't count one of them.
  5. However, some WinSocks fail with WSAEINVAL you call connect() a second time (or subsequent) on a non-blocking socket.

I discovered this while debugging a TransmitPackets problem that seemed quite random. Developer suggestions: Did you close a socket inadvertently in one part of an application without keeping another part notified? WinSock functions: With a datastream socket: connect() and FD_CONNECT WSAAsyncelect() notification message. Socket Error 11004 WSAESHUTDOWN 10058 Cannot send after socket shutdown.

WSA_NOT_ENOUGH_MEMORY Insufficient memory available WSA_OPERATION_ABORTED Overlapped operation aborted WSA_IO_INCOMPLETE Overlapped I/O object not signalled WSA_IO_PENDING Overlapped I/O will complete later WSA_INVALID_PARAMETER One or more parameters are invalid WSA_INVALID_HANDLE Event object handle WinSock description: Similar to Berkeley & Microsoft C, but in reference to sockets rather than file handles (although the descriptions in the v1.1 specification say "no more file descriptors available"). Berkeley description: A pathname lookup involved more than 8 symbolic links. Read More Here This is usually caused by one or more of the function pointers being NULL.

A socket operation encountered a dead host. Winsock Error 10054 Fix connect(), send(), recv(), et cetera). WinSock description: Partly the same as Berkeley. Berkeley description: The protocol has not been configured into the system, or no implementation for it exists.

Socket Error 10053

That they are not trying to use more than one Windows Sockets implementation simultaneously. Developer suggestions: Chances are, that if you encounter this error, your application ignored the failure of some previous function. Socket Error Codes Linux For Winsock functions that return a pointer, a return value of NULL indicates an error and a specific error number can be retrieved by calling the WSAGetLastError function. Socket Error 10054 Connection Reset By Peer For protocol and services resolution, the name or number was not found in the respective database.

email etiquette adding people to the thread vs reaching out directly What's this I hear about First Edition Unix being restored? this contact form Of the two that can fail, neither of them set an error value you can retrieve from WSAGetLastError() (refer to Chapter 10, "Support Routines" for more information on any of these Berkeley description: A file descriptor argument was out of range, referred to no open file, or a read (write) request was made to a file that was only open for writing The occurrence of an unlisted error can provide extra detail. Socket Error 10049

copies what it can into your buffer) and fails the function. WSA_QOS_EPSFILTERSPEC 11028 Invalid QoS provider-specific filterspec. If it does respond, then this problem might have been a transient one (so you can reconnect now), or the server application you were connected to might have terminated (so you have a peek here How to report trailhead bugs English fellow vs Arabic fellah Maximum server memory What commercial flight route requires the most stops/layovers from A to B?

An invalid QoS provider-specific buffer. Socket Error 10061 Connection Refused For example, the error can occur when an attempt is made to read from a file that is not open, to open an existing read-only file for writing, or to open WinSock functions: accept(), bind(), closesocket(), connect(), gethostbyaddr(), gethostbyname(), gethostname(), getpeername(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), getsockname(), getsockopt(), ioctlsocket(), listen(), recv(), recvfrom(), select(), send(), sendto(), setsockopt(), shutdown(), socket(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(),

Check that no old Windows Sockets DLL files are being accessed.

A blocking operation is currently executing. With datastream sockets, don't call connect() more than once (use select() or WSAAsyncSelect() to detect connection completion). The WinSock API does not provide access to the Network File System application protocol, so this error is irrelevant to WinSock. Windows Socket Error Windows 10 However, it is interchangeable in most cases, and all Windows Sockets functions that return one of these messages also specify WSAEAFNOSUPPORT.

TCP/IP scenario: Calling shutdown() with how=1 or how=2 sends a TCP FIN packet to the remote address, which literally means "I'm done sending." If the local host sent any more data You cannot use more than one WinSock implementation simultaneously. No more file handles are available, so no more files can be opened. http://itechnologysolutionsllc.com/socket-error/winsock-error-code-4.php Each implementation may have a maximum number of socket handles available, either globally, per process, or per thread.

This could indicate a serious failure of the network system (that is, the protocol stack that the Windows Sockets DLL runs over), the network interface, or the local network itself. The WinSock API does not provide any way to select specific name resolution protocols, server address, or record type. For instance, this error will occur if you try to run two applications that have FTP servers.

Developer suggestions: Handle this as a non-fatal error. Ping a host on the same subnet as the host you were connected to (if you know one). Check whether you have a router configured in your network system (your WinSock implementation). The error refers to content as well as value (e.g.

WinSock functions: recv(), recvfrom(), send(), sendto() WSAENAMETOOLONG (10063) File name too long. Some implementations also return this error if sendto is called on a connected SOCK_DGRAM socket (for SOCK_STREAM sockets, the to parameter in sendto is ignored) although other implementations treat this as Check the destination address you are using. Berkeley description: Some invalid argument was supplied (for example, specifying an invalid level to the setsockopt() function).

Berkeley description: A required address was omitted from an operation on a socket.
