Windows 2000 Error Messages Reference Internet Information Services Internet Service Manager Internet Service Manager WINSOCK Error: Connection refused.... WinSock functions: Any function which allocates a new descriptor: accept(), listen(), & socket(). WINSOCK Error: No buffer space is supported.... WinSock functions: WSAEUSERS (10068) Too many users.

In Linux, I could use strerror() to convert an errno code into a human-readable string. WinSock functions: accept(), close socket(), connect(), recv(), recvfrom(), send(), sendto(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort() WSAHOST_NOT_FOUND (11001) Host not found Berkeley description: No such host is known. For example, the ARPA Internet UDP protocol cannot be specified with a socket type of SOCK_STREAM. The file handle reference is no longer available.

Socket Error Codes Linux

For instance, you might get WSAEBADF in place of WSAENOTSOCK on a system that provides some socket and file handle equivalency. Berkeley description: A socket operation was attempted to an unreachable host. This would occur if WinSock aborts an established connection after data retransmission fails (receiver never acknowledges data sent on a datastream socket).

  • Setup cannot determine the remote machine's operation system type.
  • Microsoft Peer Web Services Setup required administrator privileges to run....
  • Additional functions: a generic description of the type of functions that can return this error, which may include functions other than those listed by the WinSock specification.
  • The server was unable to find the log file directory name .
  • before calling connect() or accept()).
  • up vote 14 down vote favorite 2 I'm porting some sockets code from Linux to Windows.
  • An invalid value was given for one of the arguments to a function.
  • An invalid or inconsistent flowspec was found in the QOS structure.
  • WSAECANCELLED 10103 Call has been canceled.
  • Specifically, v1.1 WinSock spec notes that this error occurs if the length of the buffer is too small.

Unable to write to filename, it is read-only or opened by someone else.... Typically their descriptions are similar. When bind is called with a wildcard address (involving ADDR_ANY), a WSAEADDRINUSE error could be delayed until the specific address is committed. Socket Error 11004 WinSock description: Same as Berkeley.

The socket is marked as non-blocking (non-blocking operation mode), and the requested operation is not complete at this time. Socket Error 10053 Note the // peculiar pass format: Even though // errString is already a pointer, we // pass &errString (which is really type LPSTR* now) // and then CAST IT to (LPSTR). The error refers to content as well as value (e.g. Get More Information Developer suggestions: If you don't detect it beforehand (e.g.

WSA_QOS_RESERVED_PETYPE 11031 Reserved policy QoS element type. Winsock Error 10054 Fix Any other type of operation might also return this error—for example, setsockopt setting SO_KEEPALIVE if the connection has been reset. Note that this error is returned by the operating system, so the error number may change in future releases of Windows. int sock = socket( AF_INET, SOCK_STREAM, IPPROTO_TCP ) ; if( sock == SOCKET_ERROR ) { // Uh oh!

Socket Error 10053

WSANO_DATA 11004 Valid name, no data record of requested type. The system detected an invalid pointer address in attempting to use a pointer argument of a call. Socket Error Codes Linux If your network system has a WinSock utility such as ping or nbtstat that shows network statistics, use this to verify that you are receiving TCP resets or ICMP Port Unreachable Socket Error 10054 Connection Reset By Peer WinSock functions: See also: WSAECONNABORTED, WSAECONNRESET, WSAENETRESET, WSAETIMEDOUT WSAEHOSTUNREACH (10065) No route to host.

Usually this occurs when a socket descriptor to a socket that cannot support this operation, for example, trying to accept a connection on a datagram socket. Check This Out To recover the orphaned sockets, you can try closing the application and restarting it to recover the open sockets; you may have to end all WinSock applications (to force an unload 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 It also occurs with functions that take a socket handle and a sockaddr structure as input parameters. Socket Error 10049

A retry at some time later may be successful. 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(), WinSock functions: gethostbyaddr(), gethostbyname(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort() Additional functions: It is strange that the asynchronous protocol and services functions can fail with this error, but the synchronous cannot. If there is more than one WINSOCK DLL on your system, be sure the first one in the path is appropriate for the network subsystem currently loaded.

A call to the WSALookupServiceEnd function was made while this call was still processing. Winsock Error 10061 Do you have a router configured? 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").

The WSAEAFNOSUPPORT is the likely substitute error for this in WinSock, although its Berkeley meaning is slightly different.

WSAECONNREFUSED 10061 Connection refused. in sendto. For protocols and services resolution, it means the respective database wasn't located. Socket Error 10061 Connection Refused 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).

The attempted operation is not supported for the type of object referenced. Berkeley description: A directory with entries other than `.'and `..' was supplied to a remove directory or rename call. WinSock description: Almost same as Berkeley. WSAEDQUOT 10069 Disc quota exceeded.

The WinSock API does not provide access to the Network File System application protocol, so this error is irrelevant to WinSock. The missing functions are getprotobyname(), getprotobynumber(), getservbyname(), and getservbyport(). 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. Once you have turned it on, please refresh the page.

Basically, you want to identify where the problem occurred. The data is the error. ... This message indicates that the key (name, address, and so on) was not found. All sockets are created with an associated address family (that is, AF_INET for Internet Protocols) and a generic protocol type (that is, SOCK_STREAM).

Use socket state in an application and/or handle this error gracefully as a non-fatal error. WinSock functions: socket() See also: WSAESOCKTNOSUPPORT WSAEPROTOTYPE (10041) Protocol wrong type for socket. try to ping the server(s)). Specifically, these error-less functions are the byte order functions ( htonl(), htons(), ntohl(), and ntohs()), the address manipulation functions (inet_addr(), and inet_ntoa), WSAGetLastError() and WSAIsBlocking().

WSANOTINITIALISED 10093 Successful WSAStartup not yet performed. An overlapped operation was canceled due to the closure of the socket, or the execution of the SIO_FLUSH command in WSAIoctl.
