Winsock Bind Error=10050


If you are using a host table exclusively, you'll need to update it to add the destination hostname and address. As you see WSAGetLastError() is an essential function to use, if you want to know why your application might be failing. There are only a few possible causes for this error: you tried to connect to the wrong port. WinSock description: Same as Berkeley. have a peek at this web-site

In WinSock it means a blocking operation was interrupted by a call to WSACancelBlockingCall. This usually means the local software knows no route to reach the remote host. WSA_QOS_EPOLICYOBJ 11025 Invalid QoS policy object. 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).

Socket Error 10054

A reserved policy element was found in the QoS provider-specific buffer.   Requirements Header Winsock2.h; Winerror.h See also Error Codes - errno, h_errno and WSAGetLastError Handling Winsock Errors FormatMessage WSAGetLastError   WSAEPROTOTYPE 10041 Protocol wrong type for socket. An invalid QoS provider-specific buffer. In other words, the Winsock you are using is not supported by the program you are using.

  • Detailed description: SO_BROADCAST is not supported on sockets of type SOCK_STREAM.
  • The Windows function is indicating a lack of required memory resources.
  • Another possible reason for the WSAEACCES error is that when the bind function is called (on Windows NT 4.0 with SP4 and later), another application, service, or kernel mode driver is bound to
  • send() & sendto(): socket not bound (for Dgram) or not yet connected (for Stream) The v1.1 specification also has a detailed description for the connect() function which says: "socket not already
  • This would occur if WinSock aborts an established connection after data retransmission fails (receiver never acknowledges data sent on a datastream socket).
  • 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.
  • User suggestions: Chances are the network subsystem is misconfigured or inactive.
  • Error Description List (0) No error WSABASEERR (10000) No error Berkeley Description: no equivalent.
  • The Windows Sockets errors are listed in alphabetical order below (they're cross-referenced in a list in numerical order further below).

Any function that takes a socket as an input parameter--except close socket()--could potentially fail with this error. WSANOTINITIALISED 10093 Successful WSAStartup not yet performed. This error occurs if an application attempts to bind a socket to an IP address/port that has already been used for an existing socket, or a socket that was not closed Socket Error 10049 WinSock description: No equivalent.

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. Socket Error Codes Linux This means another type of request to the name server will result in an answer. He also lurks around the forums as Hieran_Del8. You can attempt to avoid the error by calling WSAIsBlocking() before making any WinSock function calls.

So, for example, if a WinSock implementation doesn't support SOCK_RAW with IPPROTO_IP (or any other protocol), then the socket() call would fail with WSAEPROTONOSUPPORT (however, if it doesn't support SOCK_RAW at Socket Error 11004 WSASYSNOTREADY (10091) Network SubSystem is unavailable The Winsock implementation cannot function at this time, because the underlying system it uses to provide network services is currently unavailable. This is what occurs in Berkeley Sockets. Berkeley description: A socket operation was attempted to an unreachable host.

Which is the error we intended to get, with our little test. Is the router up and running? (You can check by pinging it, and then ping an address on the other side of it.) Try a traceroute to the destination address to Socket Error 10054 Not implemented: Name server does not perform specified operation. Socket Error 10053 See also: WSAECONNRESET, WSAENETRESET, WSAETIMEDOUT WSAECONNREFUSED (10061) Connection refused.

This error occurs if you specifically reference a protocol that isn't part of the address family you also reference. Check This Out Recv and Recvfrom: If the datagram you read is larger than the buffer you supplied, then Winsock truncates the datagram (i.e. WSAEALREADY 10037 Operation already in progress. A socket operation was attempted to an unreachable host. Socket Error 10054 Connection Reset By Peer

For protocols and services resolution, it means the respective database wasn't located. WSAEMSGSIZE (10040) Message too long. WSASYSCALLFAILURE 10107 System call failure. Source WinSock description: a quick comparison to the Berkeley counterpart, and a long description of WinSock error.

Any other type of operation might also return this error—for example, setsockopt setting SO_KEEPALIVE if the connection has been reset. Winsock Error 10054 Fix 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, Whether to handle it as a fatal error or non-fatal error depends on the application and the context, so it's up to you to decide.

This error signifies that an attempt was made to access a file (or, in some cases, a directory) in a way that is incompatible with the file's attributes.

Join your peers on the Internet's largest technical computer professional community.It's easy to join and it's free. WinSock description: No equivalent. Clearly, this oversight was not intentional. Socket Error 10061 Connection Refused WinSock functions: accept(), listen(), recv(), recvfrom(), send(), sendto() WSAEPFNOSUPPORT (10046) Protocol family not supported.

WSAHOST_NOT_FOUND for details. Once we are happy that Winsock has initialized correctly, we can now use a handy function to address any further failures. Ping a local host to verify that your local network is still functioning (if on a serial connection, see next step) Ping your local router address. have a peek here Handle the request as a non-fatal error (if possible), since some WinSock's can legally fail the request.

It also occurs with functions that take a socket handle and a sockaddr structure as input parameters. 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). For instance, if the length of a struct sockaddr is not equivalent to the sizeof(struct sockaddr). WSA_QOS_POLICY_FAILURE 11011 QoS policy failure.

Note that this error occurs rarely, because a Winsock implementation cannot reliably detect hardware problems.WSAENETUNREACH (10051) Network is unreachable A socket operation was attempted to an unreachable network.
