Check the destination address you are using. It can occur if you're trying to run too many applications (of any kind) simultaneously on your machine. 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. 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 have a peek here
WSAEPROTONOSUPPORT 10043 Protocol not supported. 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(), Berkeley description: A directory with entries other than `.'and `..' was supplied to a remove directory or rename call. You can avoid making the mistake of trying to send on a socket after you've initiated a close, by keeping track of the socket state in your application (and checking it
Developer suggestion: Use the sample code fragment in the WSAStartup() documentation in the v1.1 specification, which demonstrates how an application negotiates a Windows Sockets specification version. File name not allowed. 10064No response has been received within the given timeout period. 10065Not an FTP file. 10066Error in processing Base64. 10067Error in processing AppleSingle. 10068Error in processing Quoted-Printable. 10069FTP Small Font Size on Labels, Instructions and User Guides Client requesting admin work Probability of throwing a die Is there any way to bring an egg to its natural state (not User suggestions: Don't try running two of the same types of server applications on the same machine.
Developer suggestions: If you don't detect it beforehand (e.g. The development machine has a Bluetooth radio, the driver is Microsoft BT Stack and I can find devices using the Devices wizard through Windows. a long zero) in the sockaddr_in structure passed to sendto(). Socket Error 11004 WinSock description: Same as Berkeley.
Do not set non-zero timeout on non-blocking sockets to avoid this ambiguity (see Chapter 9 for more information). WinSock description: Similar to Berkeley. This can help you (or your support staff) to zero-in on what's wrong when your application runs into a problem. https://msdn.microsoft.com/en-us/library/windows/desktop/ms681391(v=vs.85).aspx Developer suggestion: are you trying to use an optional feature?
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 Socket Error 10061 Connection Refused Why didn’t Japan attack the West Coast of the United States during World War II? When it occurs, it could indicate a serious failure of your network system (i.e. WSAEMFILE 10024 Too many open files/sockets.
WinSock functions: send(), sendto() Additional functions: setsockopt() and any function that takes a socket (or file handle) as an input parameter. useful reference WinSock functions:
You need to call htons() to translate a constant value to network byte order before assigning it to the sin_port field in the sockaddr structure. navigate here WinSock description: Same as Berkeley. WinSock functions:
See also: WSANO_DATA, WSANO_RECOVERY, WSATRY_AGAIN WSANOTINITIALISED (10093) Successful WSAStartup() not yet performed Berkeley description: No equivalent. WinSock functions: connect(), sendto(), FD_CONNECT WSAEDQUOT (10069) Disc quota exceeded. 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. Check This Out Berkeley description: The quota system ran out of table entries.
The WinSock implementation was unable to allocate additional memory to accommodate the function request. Windows Socket Error Windows 10 Unfortunately, to find out what these errors mean you need to contact that WinSock provider. WinSock functions: listen(), FD_CONNECT Additional functions: connect(), sendto() WSAELOOP (10062) Too many levels of symbolic links.
WinSock functions: connect(), sendto(), FD_CONNECT Additional functions: Any function that does network I/O: recv(), recvfrom(), send(), FD_READ, FD_WRITE See also: WSAEHOSTUNREACH WSAENOBUFS (10055) No buffer space available. 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). WinSock description: Same as Berkeley. Socket Error 11001 after the first failed with WSAEWOULDBLOCK).
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 User suggestions: Check the obvious first: check that the destination address is a valid IP address. WSAEADDRNOTAVAIL 10049 Cannot assign requested address. this contact form WSAENETRESET (10052) Network dropped connection on reset.
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 Ping a host on the same subnet as the host you were connected to (if you know one). User suggestions: It may indicate that there are too many WinSock applications running simultaneously, but this is unlikely since most network systems have many socket handles available. User suggestions: see WSAHOST_NOT_FOUND for details.
Detailed description (from RFC 1035, "Domain Names", by P.Mockapetris): Format error: name server was unable to interpret the query. WinSock description: Same as Berkeley. This error occurs if the sin_addr is INADDR_ANY (i.e. This would occur if WinSock aborts an established connection after data retransmission fails (receiver never acknowledges data sent on a datastream socket).
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 User suggestions: see WSAECONNABORTED for details. In it's place, WinSock uses the error WSAENETUNREACH, exclusively. If you're on a serial connection, your local router is the IP address of the host you initially logged onto with SLIP or PPP.
For instance, this error will occur if you try to run two applications that have FTP servers. Berkeley description: The support for the socket type has not been configured into the system or no implementation for it exists. If you used a hostname, did it resolve to the correct address? Notice that asynchronous service and protocols functions are listed below, in addition to the hostname resolution functions.
