Windows Socket Error 10051 On Api Connect


This is not a temporary error. In this case, the 2nd application will fail with WSAEADDRINUSE. Verify that the destination IP address is correct. closesocket(): occurs on a non-blocking socket with non-zero timeout set with setsockopt() SO_LINGER. get redirected here

A function fails with WSAEAFNOSUPPORT if the address family referenced in sockaddr is not compatible with the referenced socket's protocol. WSAEAFNOSUPPORT (10047) Address family not supported by protocol family. The ICMP message means that a router can't forward the IP datagram, possibly because it didn't get a response to the ARP request (which might mean the destination host is down). The WSAAsyncSelect() FD_WRITE event is specifically designed to notify an application after a WSAEWOULDBLOCK error when buffer space is available again so send() or sendto() should succeed. https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx

Socket Error 10038

Do you have a router configured? For example, you cannot use the ARPA Internet UDP protocol with type SOCK_STREAM. Winsock description: Winsock doesn't support the sendmsg() function, and some Winsock implementations are not so strict as to require an application with a datagram socket to 'disconnect'--by calling connect with a

  1. This error is relevant to connect(), but not to send() or sendto() as it is in Berkeley Sockets.
  2. WinSock only allows a single blocking operation to be outstanding per task (or thread), and if you make any other function call (whether or not it references that or any other
  3. If you continue to receive the same error after insuring ports 20 and 21 are open, please contact the administrator of the site where you are trying to connect.
  4. WSAESERVERDOWN (10064) The server is temporarily or permanently unreachable.
  5. Detailed description (from RFC 1035, "Domain Names", by P.Mockapetris): Format error: name server was unable to interpret the query.
  6. The behavior may vary: some WinSocks might complete in background, and others may require another call to closesocket to complete.

This normally results from a loss of the connection on the remote socket due to a timeout or a reboot. WinSock description: Same as Berkeley. The v1.1 WinSock specification doesn't list any errors for these functions. Socket Error 10049 However, there's little distinction between WSAEALREADY and WSAEINVAL since a WinSock DLL cannot tell the difference between an asynchronous operation that has been cancelled and one that was never valid.

User suggestions: Some network systems have commands to report statistics. Socket Error Codes Linux Microsoft C description: Permission denied. They signal unusual error conditions for which there's no WinSock error equivalent. Browse other questions tagged python linux sockets networking or ask your own question.

You cannot use more than one WinSock implementation simultaneously. Socket Error 11004 For example, you can try to ping the server(s). WinSock description: No equivalent. connect(), send(), recv(), et cetera).

Berkeley description: Only one usage of each address is normally permitted. Detailed description: setsockopt(): WinSock generates this error if you try to set SO_KEEPALIVE but the connection has already been aborted (e.g. Socket Error 10038 You cannot mix and match. (WINSOCK DLLs must be supplied by the same vendor that provided your underlying protocol stack).You cannot use more than one Winsock implementation simultaneously.If you have more Socket Error 10054 Connection Reset By Peer Any function that takes a socket as an input parameter--except close socket()--could potentially fail with this error.

It's also possible that the local services file has an incorrect port number (although it's unlikely). Get More Info If it persists, exit Windows or reboot your machine to remedy the problem. Usually this occurs when a file descriptor refers to a file or socket that cannot support this operation, for example, trying to accept a connection on a datagram socket. So, for example, you can expect this error if a WinSock implementation doesn't support socket type SOCK_RAW within the Internet address family (AF_INET). Socket Error 10053

The Windows Sockets API provides access to "low-level" API's (like the transport protocols TCP and UDP), so this error is not relevant to WinSock. User suggestions: There may be too many Winsock applications running simultaneously, but this is unlikely since most network systems have many socket handles available. The explanation is simple and obvious: in order to connect to or send to a destination address, you need to provide the destination address. useful reference WSATRY_AGAIN (11002) Non-Authoritative Host not found This is usually a temporary error and means that the local server did not receive a response from an authoritative server.

The error can also occur in an attempt to rename a file or directory or to remove an existing directory.WSAEFAULT (10014) Bad addressThe system detected an invalid address in attempting to Windows Socket Error Windows 10 COMMAND:> LIST STATUS:> Connecting ftp data socket xxx.xx.xxx.xx:xxxx... WinSock functions: recv(), recvfrom(), send(), sendto(), with datastream sockets only.

WinSock functions: WSAEWOULDBLOCK (10035) Resource temporarily unavailable.

The Winsock description for this error is 'the specified socket type is not supported in this address family.' So, for example, you can expect this error if a Winsock implementation doesn't Unlike Berkeley, however, WinSock v1.1 doesn't ascribe this error to any functions. The connection fails due to an error or timeout. Winsock Error 10054 Fix This error indicates a shortage of resources on your system.

All rights reserved. Increase the connection timeout threshold under Global Settings > Connection. WSAEPROTONOSUPPORT (10043) Protocol not supported. this page WinSock functions: WSAETIMEDOUT (10060) Connection timed out.

WSAEINVAL (10022) Invalid argument. If this tends to occur after running certain applications for a while, it might be a symptom of an application that doesn't return system resources (like memory) properly. This usually means the local software knows no route to reach the remote host." This is a network problem, and you should fix your network. 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).

You are unlikely to encounter them. This means another type of request to the name server will result in an answer. Berkeley description: An attempt was made to access an open file (on an NFS filesystem) which is now unavailable as referenced by the file descriptor. If you still receive a 10060 error, the server may be trying to send a listing for a very large directory (with many thousands of files) causing the client to time-out

The specified socket parameter refers to a file, not a socket.WSAEDESTADDRREQ (10039) Destination address required A required address was omitted from an operation on a socket. WinSock description: No equivalent in WinSock. It could also occur if an application opens and closes sockets often, but doesn't properly close the sockets (so it leaves them open, as "orphans"). WinSock description: Same as Berkeley.

User suggestions: Two of the same types of server applications cannot use the same port on the same machine. Apparently, the Windows Sockets specification left this out by oversight. Some WinSock implementation use these errors inappropriately, but they have a particular meaning. Berkeley description: This is a temporary condition and later calls to the same routine may complete normally (also known as EAGAIN error in Berkeley Software Distribution version 4.3) WinSock description: Same
