An MX record is returned but no A record--indicating the host itself exists, but is not directly reachable. WSA_IO_INCOMPLETE (OS dependent) Overlapped I/O event object not in signaled state. An operation was attempted on a nonblocking socket with an operation already in progress--that is, calling connect a second time on a nonblocking socket that is already connecting, or canceling an Earlier in the chapter, on pp 194-197, Stevens discusses SO_REUSEADDR in detail and says that "_All_ TCP servers should specify this socket option to allow the server to be restarted in have a peek at this web-site
This error is returned from operations on nonblocking sockets that cannot be completed immediately, for example recv when no data is queued to be read from the socket. WSAENOTCONN (10057) Socket is not connected. The connection has been broken due to keep-alive activity detecting a failure while the operation was in progress. It is normal for WSAEWOULDBLOCK to be reported as the result from calling connect on a nonblocking SOCK_STREAM socket, since some time must elapse for the connection to be established.
An overlapped operation was canceled due to the closure of the socket, or the execution of the SIO_FLUSH command in WSAIoctl. If the return value is SOCKET_ERROR, WSAGetLastError can be used to retrieve a specific error code. Client # Echo client program import socket host = '192.168.1.3' # The remote host port = 50007 # The same port as used by the server s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect((host,
This error is returned if an incorrect protocol is explicitly requested in the socket call, or if an address of the wrong family is used for a socket, for example, in Another possible reason for the WSAEACCES error is that when the bind function is called (on Windows NT 4 SP4 or later), another application, service, or kernel mode driver is bound For example, the optional type SOCK_RAW might be selected in a socket call, and the implementation does not support SOCK_RAW sockets at all.

A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using sendto) no address was supplied. See "The default dynamic port range for TCP/IP has changed in Windows Vista and in Windows Server 2008" at http://support.microsoft.com/kb/929851/ So, there are now around 16383 port numbers available in the
The requested address is not valid in its context. Socket Error Codes Linux A Windows Sockets implementation may have a limit on the number of applications that can use it simultaneously. Thanks for your time and help. –JeremyK Jan 14 at 20:52 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign Typically, only one usage of each socket address (protocol/IP address/port) is permitted.
For example, if a call to WaitForMultipleObjects fails or one of the registry functions fails trying to manipulate the protocol/name space catalogs. 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. Socket Error 10048 Maya they both loop in an endless loop and continiously connect() and accept() sockets. Windows Socket Error 10048 On Api Bind A connection attempt failed because the connected party did not properly respond after a period of time, or the established connection failed because the connected host has failed to respond.
All this means that without special programming, where you are the one who selects the port number for new client connections, you cannot create more than 4000 new outgoing connections faster Check This Out Thereafter, Winsock cannot re-use a port number while the port is in the TCP TIME_WAIT state, which is a state that TCP enters to ensure that lingering transmissions and re-transmissions for Try your program on a Vista machine, and you should see the same result, but this time after 16383 connections rather than the 4000 that you observed last time. Where in this doc did you see that WSAGetLastError should be called if time limit expired? Socket Error Errno 10048
Why does multiplication lead to incompleteness where addition does not? By calling shutdown a partial close of a socket is requested, which is a signal that sending or receiving, or both have been discontinued.

This message has a slightly different meaning from WSAEAFNOSUPPORT. Socket Error 10038 WSAENOBUFS (10055) No buffer space available. On most systems that will cause the second call to bind() to fail with EINVAL, or "Invalid argument".
However, this is not correct, all sockets have been closed.

You could increase the connection request backlog and do your accepts in an outer while: import socket HOST = '' # Symbolic name meaning all available interfaces PORT = 50007 # How To Fix Socket Error Too many open sockets.
Why are some programming languages turing complete but lack some abilities of other languages? A socket operation was attempted to an unreachable host. For instance, if the length of an argument, which is a SOCKADDR structure, is smaller than the sizeof(SOCKADDR). have a peek here See WSAENETUNREACH.

For example, if data has been received but not yet acknowledged by the peer, and the local computer closes the socket with SO_LINGER set, the connection is reset and the peer If so, are you aware that server processes should usually set the SO_REUSEADDR socket option before calling bind()?
For server applications that need to bind multiple sockets to the same port number, consider using setsockopt (SO_REUSEADDR). No such host is known. A service provider returned a bogus procedure table to Ws2_32.dll. (Usually caused by one or more of the function pointers being null.) WSAINVALIDPROVIDER (OS dependent) Invalid service provider version number. Post your question and get tips & solutions from a community of 418,416 IT Pros & Developers.
In your case, you should be more interested in the return value of select(). Table 1 lists the effects of setting the SO_EXCLUSIVEADDRUSE option. If the first bind is to 10.0.0.1 and port 5150 with the SO_EXCLUSIVEADDRUSE option set, then the second bind to 10.99.99.99 and port 5150 with any or no options set succeeds. You could increase the connection request backlog and do your accepts in an outer while: import socket HOST = '' # Symbolic name meaning all available interfaces PORT = 50007 #
That's around 4000 numbers.
