Windows Socket Error Codes Python
Is that normal? Your app will grow large, buggy and suck CPU. If buflen is present, it specifies the maximum length of the buffer used to receive the option in, and this buffer is returned as a string. But if you plan to reuse your socket for further transfers, you need to realize that there is no EOT on a socket. have a peek at these guys
The standard meaning for WSAEINVAL applies to connect() (invalid argument). A value of None indicates that new socket objects have no timeout. Berkeley description: An operation that takes a long time to complete (such as a connect()) was attempted on a non-blocking socket. (see ioctl()). Berkeley description: A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket) no address was supplied.
socket.bind(address)¶ Bind the socket to address. WSA_QOS_ESDMODEOBJ 11029 Invalid QoS shape discard mode object. The software caused a connection abort because there is no space on the socket's queue and the socket cannot receive further connections. Berkeley description: Only one usage of each address is normally permitted.
- User suggestions: Check the obvious first: check that the destination address is a valid IP address.
- EINTR The receive was interrupted by delivery of a signal before any data were available; see signal(7).
- Always be sure to allocate enough space.
- For AF_INET6 address family, a four-tuple (host, port, flowinfo, scopeid) is used, where flowinfo and scopeid represents sin6_flowinfo and sin6_scope_id member in struct
- WinSock description: Same as Berkeley.
- Networking activity on the local host has not been initiated.
- Berkeley description: An attempt was made to access an open file (on an NFS filesystem) which is now unavailable as referenced by the file descriptor.
- This means that a client can detect the end of the reply by receiving 0 bytes.
- WinSock functions: socket() See also: WSAESOCKTNOSUPPORT WSAEPROTOTYPE (10041) Protocol wrong type for socket.
An invalid or unrecognized service type was found in the QoS flowspec. That's not going to help at all. Operations that were in progress fail with WSAENETRESET. Windows Socket Error Windows 10 WSAEDISCON 10101 Graceful shutdown in progress.
The overhead for this is significant (and don't do this on Windows - the overhead of process creation is enormous there). This normally results from an attempt to bind to an address that is not valid for the local computer. WSAEOPNOTSUPP 10045 Operation not supported. Xoring in constant time in Java If I receive written permission to use, without citing, a paper, is it plagiarism?
The Windows Sockets implementation documentation to be sure all necessary components are currently installed and configured correctly. Winsock Error 10054 Fix The IPv4 address is returned as a string, such as '126.96.36.199'. User suggestions: Don't try running two of the same types of server applications on the same machine. Ran out of user quota.
Socket Error 10038
socket.family¶ The socket family. http://stackoverflow.com/questions/5161167/python-handling-specific-error-codes The client sends a request, then reads a reply. Socket.error Python ENOTSOCK The argument sockfd does not refer to a socket. Socket Error Codes Linux Do you have a router configured?
It is also possible that WinSock might return this error after an application calls connect() a second time on a non-blocking socket while the connection is pending (i.e. More about the author An existing connection was forcibly closed by the remote host. In blocking mode, operations block until complete or the system returns an error (such as connection timed out). An invalid or inconsistent flowspec was found in the QoS provider-specific buffer. Socket Error 10054 Connection Reset By Peer
This is useful to find out the port number of an IPv4/v6 socket, for instance. (The format of the address returned depends on the address family -- see above.) socket.getsockopt(level, optname[, WinSock functions: bind(), connect(), sendto(), socket(), FD_CONNECT See also: WSAEPROTOTYPE WSAEALREADY (10037) Operation already in progress. WSA_QOS_EFLOWCOUNT 11023 Incorrect QoS flow count. http://itechnologysolutionsllc.com/socket-error/windows-socket-error-value.php Any application that uses a blocking socket or calls any blocking functions must handle this error.
WinSock description: Same as Berkeley. Socket Error 10049 Navigation index modules | next | previous | Python » 2.7.12 Documentation » Python HOWTOs » Socket Programming HOWTO¶ Author:Gordon McMillan Abstract Sockets are used nearly everywhere, but are one of Too many references to some kernel object.
For deterministic behavior use a numeric address in host portion.
A socket operation encountered a dead host. New in version 2.5: AF_NETLINK sockets are represented as pairs pid, groups. A protocol like HTTP uses a socket for only one transfer. Socket Error 10053 Socket objects also have these (read-only) attributes that correspond to the values given to the socket constructor.
This won't reveal too much unless you know the router addresses at the remote end, but it might help to identify if the problem is somewhere along the way. It's one way of determining whether you will block - the socket returns as readable when there's something in the buffers. SO_ACCEPTCONN, SO_DONTLINGER, SO_KEEPALIVE, SO_LINGER, SO_OOBINLINE and TCP_NODELAY are not supported on sockets of type SOCK_DGRAM. news 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)
SO_ACCEPTCONN, SO_ERROR, SO_TYPE: are read-only options, so they work with getsockopt(), but not with setsockopt() Developer suggestions: Check the parameters. In this case, it might be possible to check the count of TCP RST packets received, or ICMP Port Unreachable packets. WSAENOPROTOOPT 10042 Bad protocol option. Parameter types are somewhat higher-level than in the C interface: as with read() and write() operations on Python files, buffer allocation on receive operations is automatic, and buffer length
In Python, it's a piece of cake, but it's close enough to the C version that if you understand select in Python, you'll have little trouble with it in C:
