Wsaenetdown (10050)


This error is returned by WSAStartup if the Windows Sockets implementation cannot function at this time because the underlying system it uses to provide network services is currently unavailable. When bind is called with a wildcard address (involving ADDR_ANY), a WSAEADDRINUSE error could be delayed until the specific address is committed. The specified class was not found. A socket operation was attempted to an unreachable host. http://laptopdeathmatch.com/socket-error/wsaenetdown-ownload.php

A socket operation failed because the destination host is down. Developer suggestions: Things an application developer can do to avoid the error. Request refused: name server refuses to satisfy your query for policy reasons. Typically, though, WinSock generates this error when it receives a "host unreachable" ICMP message from a router.

Socket Error 10054

WinSock functions: WSACancelAsyncRequest() Additional functions: Berkeley sockets connect() returns this error on subsequent calls, after an initial call on a non-blocking socket. WSAESTALE 10070 Stale file handle reference. An invalid FILTERSPEC was found in the QoS provider-specific buffer. The behavior may vary: some WinSocks might complete in background, and others may require another call to closesocket to complete.

The file handle reference is no longer available. Symbol Description WSAENETDOWN A socket operation encountered a dead network. Click to search on msdn, to search on stackoverflow. An overlapped operation was canceled due to the closure of the socket, or the execution of the SIO_FLUSH command in WSAIoctl. Socket Error 10054 Connection Reset By Peer WSA_QOS_RECEIVERS 11005 QoS receivers.

SO_ACCEPTCONN, SO_ERROR, SO_TYPE: are read-only options, so they work with getsockopt(), but not with setsockopt() Developer suggestions: Check the parameters. What Is A Socket Error An invalid policy object was found in the QoS provider-specific buffer. WinSock functions: accept(), bind(), connect(), listen(), send(), sendto(), socket(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort(), FD_CONNECT Additional functions: Any other functions that use network system buffer space, like the "database functions", Berkeley description: An attempt was made to access a file in a way forbidden by its file access permissions.

Berkeley description: An operation that takes a long time to complete (such as a connect()) was attempted on a non-blocking socket. (see ioctl()). Socket Error 10049 In some cases these errors are platform dependent. If you have more than one WINSOCK DLL on your system, be sure the first one in the path is appropriate for the network subsystem currently loaded. I tested it with the actual private LAN address of my machine.

What Is A Socket Error

Some of those possible events include improper deletion of applications and hardware and incomplete installations or uninstallations. The QoS request was rejected because the policy system couldn't allocate the requested resource within the existing policy. Socket Error 10054 This is what occurs in Berkeley Sockets. Socket Error 10053 An example is using a broadcast address for sendto without broadcast permission being set using setsockopt(SO_BROADCAST).

WinSock description: No equivalent. This can also result from connect, sendto, WSAConnect, WSAJoinLeaf, or WSASendTo when the remote address or port is not valid for a remote computer (for example, address or port 0). What is difference b/w:-            ipaddr = inet_addr((const char *)m_sAddress);    and    ipaddr = (IPAddr)m_sAddress; Sometime when I press my ping button twice or thrice with TCP, UDP, ICMP, ARP, DNS) that typically causes the error. Socket Error 10038

WinSock functions: socket() See also: WSAEPROTOTYPE, WSAEPROTONOSUPPORT WSAESTALE (10070) Stale NFS file handle. 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 We suggest local configuration changes that might remedy the problem, and network and server conditions that might be the cause. http://laptopdeathmatch.com/socket-error/winsock-fehler-10050.php WinSock description: Same as Berkeley.

after the first failed with WSAEWOULDBLOCK). Wsagetlasterror 0 Returned by WSARecv and WSARecvFrom to indicate that the remote party has initiated a graceful shutdown sequence. They signal unusual error conditions for which there's no WinSock error equivalent.

It also occurs with functions that take a socket handle and a sockaddr structure as input parameters.

That is what inet_addr is for...it takes a string, and gives the DWORD form of the address. Although most of this appendix is for application developers, the User suggestions contain information that end-users and application support personnel might also find useful when an application fails. WSA_QOS_EPOLICYOBJ 11025 Invalid QoS policy object. Wsaeconnreset 10054 The Windows Sockets API does not have analogs for the Berkeley perror() and herror() functions that take the error value as input, and output the (short) text of each error value

The second one is 1 byte too large, but that is not the problem. This error, and the one yesterday, are not particularly informative, but...when I correct the size error that I just mentioned, the code runs on my machine with the expected result. (So Some of these neglected error values are among those mentioned earlier that provide "finer resolution" on different WinSock implementations. You have given a size that is larger than your SendData buffer.dwRetVal = IcmpSendEcho(hIcmpFile, ipaddr, SendData, sizeof(SendData) + sizeof(ICMP_ECHO_REPLY), NULL, ReplyBuffer, ReplySize, 2000);dwRetVal = IcmpSendEcho(hIcmpFile, ipaddr, SendData, sizeof(SendData), NULL, ReplyBuffer, ReplySize,

Detailed descriptions (relevant to socket states): accept(): listen() was not invoked prior to accept() bind(): socket already bound to an address getsockname(): socket not bound with bind() listen(): socket not bound Some invalid argument was supplied (for example, specifying an invalid level to the setsockopt function).
