With datastream sockets, don't call connect() more than once (use select() or WSAAsyncSelect() to detect connection completion). I don't know what else 2 do, any ideas on how to manage this protocols? Developer suggestions: Every application that uses non-blocking sockets must be prepared for this error on any call to the functions mentioned below. WSA_IO_INCOMPLETE 996 Overlapped I/O event object not in signaled state. http://jactionscripters.com/socket-error/windows-socket-error-10042.php
On a datastream socket, the connection was reset. It means that there is a blocking operation outstanding. The specified file handle is not a valid file-handle value or does not refer to an open file; or an attempt was made to write to a file or device opened Alternately, you could call setsockopt(SO_REUSEADDR) to allow duplicate local addresses in a single application, but this is a kludgy approach (i.e. https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx
The name you have used is not an official hostname or alias. This indicates that some sort of nonrecoverable error occurred during a database lookup. Cannot translate a name.
Use socket state in an application and/or handle this error gracefully as a non-fatal error. A blocking operation is currently executing. Too many references to some kernel object. Socket Error Codes Linux Developer suggestions: If you don't detect it beforehand (e.g.
Berkeley description: An operation was attempted on something that is not a socket. Winsock Error 10053 That only make me anger. WinSock description: Same as Berkeley; the option is unknown or unsupported. after failed calls to inet_addr() or gethostbyname()), then simply test your address value for zero before you pass it to sendto().
Developer suggestions: You need to be prepared to handle this error on any functions that reference blocking sockets, or any calls to blocking functions, if you allow the user to cancel Winsock Error 10061 This error occurs if the sin_addr is INADDR_ANY (i.e. Try a traceroute to the destination address to check that all the routers are functioning. WSA_QOS_EPSFILTERSPEC 11028 Invalid QoS provider-specific filterspec.
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"). WSA_QOS_NO_RECEIVERS 11008 QoS no receivers. Socket Error 10054 Do not set non-zero timeout on non-blocking sockets to avoid this ambiguity (see Chapter 9 for more information). What Is A Socket Error An invalid FILTERSPEC was found in the QoS provider-specific buffer.
As far as I can see, the current constant is set to 5, and the article says it should be 12 cmr added A-windows A-io labels Jan 1, 2015 cmr commented http://jactionscripters.com/socket-error/winsock-error-997.php Additional functions: With a datagram socket: send() or sendto(), or FD_READ. DimipHostInfoAsIPHostEntry=Dns.Resolve(Dns.GetHostName()) DimipAddressAsIPAddress=ipHostInfo.AddressList(0) DimlocalEndPointAsNewIPEndPoint(ipAddress,8000) 'CreateaTCP/IPsocket. In some instances, it also refers to the current state of the socket - for instance, calling accept on a socket that is not listening.WSAEISCONN (10056)Socket is already connected.A connect request Socket Error 10054 Connection Reset By Peer
A retry at some time later may be successful.WSAVERNOTSUPPORTED (10092)WINSOCK.DLL version out of range.The current Windows Sockets implementation does not support the Windows Sockets specification version requested by the program. Developer suggestions: WSAStartup() failed, and you didn't detect it, or it wasn't called for the current task at all, or you called WSACleanup() too many times. WSA_QOS_REQUEST_CONFIRMED 11009 QoS request confirmed. http://jactionscripters.com/socket-error/winsock-2-0-error.php In fact, on occasion you can benefit if the WinSock implementation returns these other errors.
Handle the request as a non-fatal error (if possible), since some WinSock's can legally fail the request. Socket Error 10061 Connection Refused Too many links were encountered in translating a pathname. These error codes and a short text description associated with an error code are defined in the Winerror.h header file.
Unfortunately, to find out what these errors mean you need to contact that WinSock provider. By calling shutdown a partial close of a socket is requested, which is a signal that sending or receiving or both has been discontinued.WSAESOCKTNOSUPPORT (10044)Socket type not supported.The support for the Unlike Berkeley, however, WinSock v1.1 doesn't ascribe this error to any functions. Winsock Error Windows 7 The Windows Sockets errors are listed in alphabetical order below (they're cross-referenced in a list in numerical order further below).
If so, treat this as a non-fatal error and ignore it, if possible. The behavior may vary: some WinSocks might complete in background, and others may require another call to closesocket to complete. On the server end, you could use a network system utility similar to BSD's "netstat -a" command to check that your server is running, and listening on the right port number. More about the author This usually results from trying to connect to a service that is inactive on the foreign host—that is, one with no server application running.
This may indicate the file was deleted on the NFS server or some other catastrophic event occurred. The file's permission setting does not allow the specified access. DimbytesReadAsInteger=handler.EndReceive(ar) IfbytesRead>0Then 'Theremightbemoredata,sostorethedatareceivedsofar. WSAECONNRESET (10054) Connection reset by peer.
Berkeley description: A request to send data was disallowed because the socket had already been shut down with a previous shutdown() call. It is normal for WSAEWOULDBLOCK to be reported as the result from calling connect on a non-blocking SOCK_STREAM socket, since some time must elapse for the connection to be established.WSAHOST_NOT_FOUND (11001)Host Berkeley description: Some invalid argument was supplied (for example, specifying an invalid level to the setsockopt() function). Windows Sockets Error Codes Most Windows Sockets 2 functions do not return the specific cause of an error when the function returns.
As you can see from the comprehensive list of WinSock functions, this error is the catch-all. WinSock description: Almost same as Berkeley. Additional functions: Any functions that takes a pointer as an input parameter: inet_addr(), inet_ntoa(), ioctlsocket(), gethostbyaddr(), gethostbyname(), getservbyname(), getservbyport(), WSAAsyncGetHostByName(), WSAAsyncGetHostByAddr(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber, WSAAsyncGetServByName(), WSAAsyncGetServByPort(), WSASetBlockingHook() WSAEHOSTDOWN (10064) Host is down. For inet_addr(), this could mean the content of the buffer passed or the buffer itself is invalid.
WinSock description: Same as Berkeley, and then some. WinSock description: No equivalent. May 27 '10 #4 reply P: 6 Goyem Banfa, I'm using a SocketType.Stream because i'm using a two way tcp connection. For instance, you might get WSAEBADF in place of WSAENOTSOCK on a system that provides some socket and file handle equivalency.
Banfa, I did a research in what you suggest and added a Thread.Sleep before the BeginAccept and i got the same response. The usual example for this is a hostname -> address translation attempt (using gethostbyname or WSAAsyncGetHostByName) which uses the DNS (Domain Name Server), and an MX record is returned but no Client applications usually need not call bind at all—connect chooses an unused port automatically. User suggestions: see WSAHOST_NOT_FOUND for details.
Clearly, this oversight was not intentional. User suggestions: Try to ping the destination host, to see if you get the same results (chances are, you will). Windows Sockets only allows a single blocking operation—per- task or thread—to be outstanding, and if any other function call is made (whether or not it references that or any other socket) This error occurs if an application passes an invalid pointer value, or if the length of the buffer is too small.
