Socket Error 6

Contents

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. WSAEINVAL (10022) Invalid argument. Its default value is 0. New in version 2.5. http://whistlemedia.net/socket-error/socket-error-wsaewouldblock-the-socket-would-block.html

Returned when a system call that should never fail does fail. Some of the types of things you will find under some errors are: Microsoft C description: the first few WinSock errors are carry-overs from the standard 'C' runtime library. This error occurs if an application passes an invalid pointer value, or if the length of the buffer is too small. WSANO_DATA 11004 Valid name, no data record of requested type.

Interprocess Communication and Networking » © Copyright 1990-2016, Python Software Foundation. A socket operation encountered a dead host. Specifically, the v1.1 Windows Sockets specification notes the domain name system (DNS) errors "FORMERR, REFUSED, and & NOTIMP.

  • socket.bind(address)¶ Bind the socket to address.
  • The optional protocol name, if given, should be 'tcp' or 'udp', otherwise any protocol will match.
  • A system call that should never fail has failed.
  • Unlike send(), this method continues to send data from string until either all data has been sent or an error occurs. None is returned on success.
  • Unfortunately, to find out what these errors mean you need to contact that WinSock provider.
  • Developer suggestion: are you trying to use an optional feature?
  • Similarly, port can contain a string port name or a numeric port number.
  • If you want to know the current machine's IP address, you may want to use gethostbyname(gethostname()).

WinSock functions: gethostbyaddr(), gethostbyname(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort(), See also: WSAHOST_NOT_FOUND, WSANO_DATA, WSATRY_AGAIN WSASYSNOTREADY (10091) Network subsystem is unavailable Berkeley description: No equivalent. Note that exactly what is valid depends on the underlying C implementation of inet_aton(). inet_aton() does not support IPv6, and inet_pton() should be used instead for IPv4/v6 dual WinSock functions: getsockopt(), setsockopt() Additional functions: Bad IP headers can cause routers and remote hosts to issue ICMP "parameter problem" messages, which result in a ENOPROTOOPT error on Berkeley-derived systems. Socket Error 10049 For example, the value given for the origin when positioning a file pointer (by means of a call to fseek) is before the beginning of the file.

If the hostname resolution uses a local host table, it's possible you resolved to an obsolete address. Socket Error 10054 There are no QoS receivers. Detailed description (from RFC 1035, "Domain Names", by P.Mockapetris): Format error: name server was unable to interpret the query. WSA_QOS_RECEIVERS 11005 QoS receivers.

These errors might be reported on any function that does network I/O (e.g. Socket Error 11004 You signed in with another tab or window. These conditions are more likely to be indicated by the error WSAETIMEDOUT. The Windows Sockets errors are listed in alphabetical order below (they're cross-referenced in a list in numerical order further below).

Socket Error 10054

WSA_QOS_EOBJLENGTH 11022 Invalid QoS object length. this canonname will be a string representing the canonical name of the host if AI_CANONNAME is part of the flags argument; else canonname will be empty. Socket Error Codes Linux socket.socketpair([family[, type[, proto]]])¶ Build a pair of connected socket objects using the given address family, socket type, and protocol number. Socket Error 10053 Note that this error is returned by the operating system, so the error number may change in future releases of Windows.

A retry at some time later may be successful. his comment is here To save myself, and a few others, some time in the future... /usr/include/asm-generic/errno-base.h #ifndef _ASM_GENERIC_ERRNO_BASE_H #define _ASM_GENERIC_ERRNO_BASE_H #define EPERM 1 /* Operation not permitted */ #define ENOENT 2 /* No such If so, then the application might have had a problem resolving the name (see suggestions at WSATRY_AGAIN for more information). NFS is "network-related" in the strictest sense, but the Network File System protocol is an application protocol (i.e. Socket Error 10054 Connection Reset By Peer

Berkeley description: An asynchronous signal (such as SIGINTor SIGQUIT) was caught by the process during the execution of an interruptible function. Berkeley description: A write to an ordinary file, the creation of a directory or symbolic link, or the creation of a directory entry failed because the user's quota of disk blocks This is useful when conversing with a program that uses the standard C library and needs objects of type struct in_addr, which is the C type for the 32-bit this contact form For example, you shouldn't necessarily expect to be able to use NS addresses with ARPA Internet protocols.

If how is SHUT_WR, further sends are disallowed. How To Fix Socket Error WSAEISCONN (10056) Socket is already connected. The values for WSANO_DATA and WSANO_ADDRESS (11004) are duplicates, so we don't count one of them.

a "high-level" protocol). 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 WSAEBADF (10009) Bad file descriptor. Socket Error 10061 socket.getsockname()¶ Return the socket's own address.

Sockets are automatically closed when they are garbage-collected. WinSock description: No equivalent. On a datastream socket, some applications use this error with a non-blocking socket calling connect() to detect when a connection attempt has completed, although this is not recommended since some WinSocks http://whistlemedia.net/socket-error/socket-error-10057-â-socket-is-not-connected.html The error can occur when the local network system aborts a connection.

The behavior may vary: some WinSocks might complete in background, and others may require another call to closesocket to complete. WinSock functions: WSAEACCES (10013) Permission denied. Detailed description: setsockopt(): WinSock generates this error if you try to set SO_KEEPALIVE but the connection has already been aborted (e.g. WinSock functions: send(), sendto(), setsockopt() Additional functions: Any function that does network I/O: recv(), recvfrom(), FD_READ, FD_WRITE See also: WSAECONNABORTED, WSAECONNRESET, WSAETIMEDOUT WSAENETUNREACH (10051) Network is unreachable.

WinSock description: No equivalent in WinSock. User suggestions: see WSAHOST_NOT_FOUND for details. socket.listen(backlog)¶ Listen for connections made to the socket. WSA_IO_PENDING 997 Overlapped operations will complete later.

See also: WSAECONNABORTED, WSAECONNRESET, WSAENETRESET WSAETOOMANYREFS (10059) Too many references; can't splice Berkeley description: too many references to some kernel-level object; the associated resource has run out. If the signal handler performs a normal return, the interrupted function call will seem to have returned the error condition.
