WSANO_DATA (11004) Valid name, no data record of requested type Berkeley description: The requested name is valid, but does not have an Internet IP address at the name server. socket.getaddrinfo(host, port[, family[, socktype[, proto[, flags]]]])¶ Translate the host/port argument into a sequence of 5-tuples that contain all the necessary arguments for creating a socket connected to that service. have bounds, or specific values) might return this error. In this case, it might be possible to check the count of TCP RST packets received, or ICMP Port Unreachable packets. navigate to this website

WSAENETDOWN 10050 Network is down. WinSock functions: WSACancelAsyncRequest() Additional functions: Berkeley sockets connect() returns this error on subsequent calls, after an initial call on a non-blocking socket. WSAENOPROTOOPT (10042) Bad protocol option. The first name which includes a period is selected. https://support.microsoft.com/en-us/kb/819124

Socket.error Python

The select call is blocking, but you can give it a timeout. This indicates that some sort of nonrecoverable error occurred during a database lookup. The connection has been broken due to keep-alive activity detecting a failure while the operation was in progress. Berkeley description: A connect request was made on an already connected socket; or, a sendto() or sendmsg() request on a connected socket specified a destination when already connected.

The call has been canceled. WSAECONNREFUSED 10061 Connection refused. But I never came that far. Windows Socket Error Windows 10 Browse other questions tagged python sockets exception exception-handling or ask your own question.

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. WSA_QOS_ESDMODEOBJ 11029 Invalid QoS shape discard mode object. Berkeley description: The protocol has not been configured into the system, or no implementation for it exists. https://docs.python.org/2/library/socket.html However, the WSAEPROTONOSUPPORT is another possible equivalent for WinSock to use in place of this error.

WSA_QOS_EFILTERTYPE 11020 Invalid QoS filter type. Winsock Error 10054 Fix WSAEAFNOSUPPORT (10047) Address family not supported by protocol family. An unrecognized object was found in the QoS provider-specific buffer. The flags argument can be one or several of the AI_* constants, and will influence how results are computed and returned.

Socket Error 10038

The example requires administrator privileges to modify the interface: import socket # the public network interface HOST = socket.gethostbyname(socket.gethostname()) # create a raw socket and bind it to the public interface On a datastream socket, the connection was reset. Socket.error Python An invalid shape discard mode object was found in the QoS provider-specific buffer. Socket Error Codes Linux socket.getpeername()¶ Return the remote address to which the socket is connected.

Where network order is host order, these do nothing, but where the machine is byte-reversed, these swap the bytes around appropriately. useful reference The return value is a string representing the data received. Are you using an optional level or socket option that may not be supported on all WinSock implementations? This is a generic error code, returned under various conditions. Socket Error 10054 Connection Reset By Peer

  • All errors raise exceptions.
  • WinSock functions: Additional functions: For Berkeley compatibility, the socket() function should fail with this error if an unsupported address family is requested.

User suggestions: see WSAENETUNREACH for details WinSock functions: Additional functions: Any function that does network I/O. New in version 2.4. How can I build a board to mount climbing holds in my house? my review here The socket must not already be bound. (The format of address depends on the address family -- see above.) Note This method has historically accepted a pair of parameters for

Berkeley description: An operation was attempted on something that is not a socket. Socket Error 10049 To find the fully qualified domain name, use the function getfqdn(). gethostbyaddr() supports both IPv4 and IPv6. socket.inet_ntoa(packed_ip)¶ Convert a 32-bit packed IPv4 address (a string four characters in length) to its standard dotted-quad string representation (for example, ‘123.45.67.89').

WSA_QOS_EOBJLENGTH 11022 Invalid QoS object length.

Put code in that will make sure they get closed properly on both sides. The socket must be in blocking mode (it can not have a timeout). Try a traceroute to the destination address to check that all the routers are functioning. Socket Error 10053 Or, usually better, use select()/poll() to monitor the sockets. –mhawke Oct 27 at 22:50 Does socket.timeout also correspond with a specific errno.?, if you would catch it with socket.error

The socket type should be SOCK_STREAM (the default), SOCK_DGRAM or perhaps one of the other SOCK_ constants. A connect request was made on an already-connected socket. The behavior may vary: some WinSocks might complete in background, and others may require another call to closesocket to complete. http://pdctoday.com/socket-error/windows-socket-error-on-api.php In blocking mode, operations block until complete or the system returns an error (such as connection timed out).

WinSock functions: connect(), sendto(), FD_CONNECT WSAEDQUOT (10069) Disc quota exceeded. 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. Address family, socket type and protocol number are as for the socket() function above. Some of these functions cannot fail, which explains their absence from the error list below.

Availability: Unix. In case no fully qualified domain name is available, the hostname as returned by gethostname() is returned. recv(), recvfrom(), send(), sendto(): MSG_OOB was specified, but the socket is not of type SOCK_STREAM Developer suggestions: don't do that. socket.send(string[, flags])¶ Send data to the socket.

WinSock description: No equivalent in WinSock. socket.connect_ex(address)¶ Like connect(address), but return an error indicator instead of raising an exception for errors returned by the C-level connect() call (other problems, such as "host not found," can New in version 2.6. An error with the underlying traffic control (TC) API as the generic QoS request was converted for local enforcement by the TC API.

for functions that use h_errno in the C API, including gethostbyname_ex() and gethostbyaddr().
