ftp winsock error codes Star Tannery, Virginia

An example is using a broadcast address for sendto without broadcast permission being set using setsockopt(SO_BROADCAST). WSA_NOT_ENOUGH_MEMORY 8 Insufficient memory available. Bad command or file name Halt and Catch Fire HTTP 418 Out of memory Lists List of HTTP status codes List of FTP server return codes Related Kill screen Spinning pinwheel The Windows Sockets API provides access to "low-level" API's (like the transport protocols TCP and UDP), so this error is not relevant to WinSock.

See WSASYSNOTREADY for details. An incorrect number of QoS FILTERSPECs were specified in the FLOWDESCRIPTOR. By calling shutdown() you do a partial close of a socket, which means you have discontinued sending. Typically, though, WinSock generates WSAENETUNREACH when it receives a "host unreachable" ICMP message from a router instead of WSAEHOSTUNREACH.

WinSock functions: getsockopt(), setsockopt() Additional functions: Bad IP headers can cause routers and remote hosts to issue ICMP "parameter problem" messages, which result in a ENOPROTOOPT error on Berkeley-derived systems. You can monitor available memory with Program Manager's "Help/About..." command. TCP/IP scenario: In BSD-compatible implementations, the local network system generates this error if there isn't a default route configured. It is a non-fatal error, and the operation should be retried later.

An address incompatible with the requested protocol was used. 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). Berkeley description: An attempt was made to access a file in a way forbidden by its file access permissions. For instance, you might get WSAEBADF in place of WSAENOTSOCK on a system that provides some socket and file handle equivalency.

You could use this to verify that you're receiving TCP resets or ICMP Port Unreachable packets each time you attempt to connect. WinSock description: Almost same as Berkeley. WSAECONNREFUSED (10061)Connection refused.No connection could be made because the target machine actively refused it. The name is not an official host name or alias, or it cannot be found in the database(s) being queried.

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", Any other type of operation might also return this error—for example, setsockopt setting SO_KEEPALIVE if the connection has been reset. Do a traceroute to try to determine where the failure occurs along the route between your host and the destination host. A socket operation encountered a dead host.

WSAENOPROTOOPT 10042 Bad protocol option. Developer suggestions: Handle this as a non-fatal error. It is normal for WSAEWOULDBLOCK to be reported as the result from calling connect on a non-blocking SOCK_STREAM socket, since some time must elapse for the connection to be established. A new request may be initiated. 3xx Positive Intermediate reply The command has been accepted, but the requested action is being held in abeyance, pending receipt of further information.

Note: Although connect() and FD_CONNECT also have this error listed, the documentation specifically states that WSAEADDRNOTAVAIL is appropriate if INADDR_ANY is passed as a destination address. If it persists, exit Windows or reboot your machine to remedy the problem. WinSock description: The WinSock implementation cannot function at this time, because the underlying system it uses to provide network services is currently unavailable. Check that the hostname or IP address has been entered correctly. 11004 - Valid name, no data record of requested type.This error generally indicates that the specified FTP server name is

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. An invalid value was given for one of the arguments to a function. The requested name is valid and was found in the database, but it does not have the correct associated data being resolved for. This error occurs if an application passes an invalid pointer value, or if the length of the buffer is too small.

socket is not listening). A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent.Normally an FTP server runs on a specific The server application might need to call htons() to translate the port to network byte order in the sockaddr structure. A required address was omitted from an operation on a socket.

See also: These point to other errors that are similar. If you can connect to other FTP addresses, it is likely the site generating the error 10061 is refusing to accept your connection because of security privileges or because it is Not implemented: name server does not perform specified operation. The WinSock implementation will not allow you to send after this.

However, they don't need to set the WinSock error value, because there's only one reason for their failure: the input parameter was invalid. WSA_IO_PENDING 997 Overlapped operations will complete later. Show you're human. WinSock functions: accept(), bind(), closesocket(), connect(), gethostbyaddr(), gethostbyname(), gethostname(), getpeername(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), getsockname(), getsockopt(), ioctlsocket(), listen(), recv(), recvfrom(), select(), send(), sendto(), setsockopt(), shutdown(), socket(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(),

All rights reserved. WinSock functions: WSAEWOULDBLOCK (10035) Resource temporarily unavailable. calling connect a second time on a non-blocking socket that is already connecting, or canceling an asynchronous request (WSAAsyncGetXbyY) that has already been canceled or completed. User suggestions: see WSAHOST_NOT_FOUND for details.

This is a generic error code, returned under various conditions. WSAINVALIDPROCTABLE OS Dependent Invalid procedure table from service provider. A socket operation encountered a dead network. Ping a local host to verify that your local network is still functioning (if on a serial connection, see next step) Ping your local router address.

This is one of the most frequent errors and one of the best to encounter, since it's one of the least ambiguous. For example, if a call to WaitForMultipleObjects fails or one of the registry functions fails trying to manipulate the protocol/namespace catalogs. Check that no old Windows Sockets DLL files are being accessed. Each implementation may have a maximum number of socket handles available, either globally, per process, or per thread.

These codes come from an FTP Server to inform you about the status of your request. 100 Series: The requested action is being initiated; expect another reply before proceeding with a The specified class was not found. 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 Users should check: that the WINSOCK.DLL file is in the current path, that the WINSOCK.DLL file is from the same vendor as the underlying protocol stack.

This message has a slightly different meaning from WSAEAFNOSUPPORT. WSA_QOS_REQUEST_CONFIRMED 11009 QoS request confirmed. Error Description List (0) No error WSABASEERR (10000) No error Berkeley Description: no equivalent.

An invalid policy object was found in the QoS provider-specific buffer.
