You could use this to verify that you're receiving TCP resets or ICMP Port Unreachable packets each time you attempt to connect. Developer suggestions: WSAStartup() failed, and you didn't detect it, or it wasn't called for the current task at all, or you called WSACleanup() too many times. Of the two that can fail, neither of them set an error value you can retrieve from WSAGetLastError() (refer to Chapter 10, "Support Routines" for more information on any of these WinSock description: Same as Berkeley. navigate here
For WinSock, this error is equivalent to Berkeley's EHOSTUNREACH error, the catch-all error for unreachable hosts. "You can't get there from here." TCP/IP scenario: The local network system could generate this This error may also result if a connection was broken due to keep-alive activity detecting a failure while one or more operations are in progress. WinSock functions: recv(), recvfrom(), send(), sendto(), FD_CLOSE Additional functions: Any function that does I/O on the network could generate this error. WinSock functions:
Windows Socket Error 10054
A completion indication will be given later when the operation has been completed. This normally results if the peer application on the remote host is suddenly stopped, the host is rebooted, the host or remote network interface is disabled, or the remote host uses See WSAENETUNREACH. WinSock description: Same as Berkeley.
If the hostname resolution uses a local host table, it's possible you resolved to an obsolete address. Return code/valueDescription WSA_INVALID_HANDLE 6 Specified event object handle is invalid. By calling shutdown() you do a partial close of a socket, which means you have discontinued sending. Wsagetlasterror 0 and entered my Hostname and Username, and did not change any other information, and clicked Connect button.
WSASYSNOTREADY 10091 Network subsystem is unavailable. What Is A Socket Error 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", Note that this error is returned by the operating system, so the error number may change in future releases of Windows. Home What's New Products Download Purchase Support About Us Contact Forums VanDyke Software Forums > General WSAENOTCONN: Not Connected User Name Remember Me?
All sockets are created with an associated address family (that is, AF_INET for Internet Protocols) and a generic protocol type (that is, SOCK_STREAM). Wsaeconnreset 10054 An application used a Windows Sockets function which directly maps to a Windows function. Developers should consider handling the referenced errors similarly. I do know that FSXFollow is one of the programs allowed through my firewall so I'm not sure why it should suddenly show this error.

What Is A Socket Error
Thirteen errors have "
No connection could be made because the target computer actively refused it. Downloads and tools Windows 10 dev tools Visual Studio Windows SDK Windows Store badges Essentials API reference (Windows apps) API reference (desktop apps) Code samples How-to guides (Windows apps) Learning resources Most likely one of them failed and that's why you are getting errors later on. –Jeremy Friesner Feb 8 '13 at 0:19 2 You're not using the returned SOCKET from This is one of the most frequent errors and one of the best to encounter, since it's one of the least ambiguous. Socket Error 10054 Connection Reset By Peer
WinSock functions: send(), sendto() Additional functions: setsockopt() and any function that takes a socket (or file handle) as an input parameter. Detailed description: send() & sendto(): the requested address is a broadcast address, but the appropriate flag was not set (i.e. Windows Sockets Error Codes Most Windows Sockets 2 functions do not return the specific cause of an error when the function returns. WinSock description: Same as Berkeley.
WSAECONNREFUSED 10061 Connection refused. Socket Error 11004 you're trying to share a socket between tasks). WSAELOOP 10062 Cannot translate name.
Berkeley description: The quota system ran out of table entries.
TCP/IP scenario: Calling shutdown() with how=1 or how=2 sends a TCP FIN packet to the remote address, which literally means "I'm done sending." If the local host sent any more data Check your WinSock implementation documentation to be sure all necessary components are currently installed and configured correctly. WSAESHUTDOWN 10058 Cannot send after socket shutdown. Socket Error Codes Linux Is the router up and running (check by pinging it, and then ping an address on the other side of it)?
They signal unusual error conditions for which there's no WinSock error equivalent. NOTE: The MAKEWORD macro referenced in the code fragment is not available in the WINSOCK.H header file or in any standard header files. The requested name is valid and was found in the database, but it does not have the correct associated data being resolved for. WSAEACCES 10013 Permission denied.
It can occur if you're trying to run too many applications (of any kind) simultaneously on your machine. Berkeley description: Only one usage of each address is normally permitted. It means that there is a blocking operation outstanding. 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.
But that's not to say you shouldn't still be prepared. For example, you shouldn't necessarily expect to be able to use NS addresses with ARPA Internet protocols. This usually means the local software knows no route to reach the remote host. 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.
For instance, this error will occur if you try to run two applications that have FTP servers. A socket operation was attempted to an unreachable host. 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.
