FTP Server Test2010-08-11 04:00:17 TCP/IP socket error. This error occurs when an operation such as send or recv was performed on a socket which was in an invalid state for the attempted operation. WSAEMFILE 10024 Too many open files. 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 https://gist.github.com/gabrielfalcao/4216897

An unknown, invalid or unsupported option or level was specified in a getsockopt or setsockopt call. This is not actually an error. An unknown or conflicting QoS style was encountered. The host name returned by the server is longer 100 characters.

Errors arising in the network communication between the Names Server and Names Client, thus stopping these programs from initialising or communicating. (Under Windows NT, the error values returned are positive values, 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. trying to locate realistic examples often pushes you into complex examples using hundreds of lines of code to do real work. The next area to examine would be to double check that the Dotted IP numbers in the INI file setting “ServerAddress=” are correct and that the Port number is the same

Note that closesocket can take a few minutes to release the socket. If the Server is definitely running, check that it hasn't crashed. WSAESOCKTNOSUPPORT 10044 Socket type not supported. http://www.ibm.com/support/knowledgecenter/SSLTBW_2.1.0/com.ibm.zos.v2r1.f54ug00/ispug179.htm For example, the ARPA Internet UDP protocol cannot be specified with a socket type of SOCK_STREAM.

Note that this error is returned by the operating system, so the error number may change in future releases of Windows. If so, then unless you are running the Server from an account with root privileges you must use port number 1024 or greater. WSA_QOS_NO_SENDERS 11007 No QoS senders. Also, a firewall running on the host or client machine can be blocking transmission.

EDESTUNREACH (159)Destination unreachable (ICMP). http://infocenter.arm.com/help/topic/com.arm.doc.dui0144b/BABCHBGH.html WSA_QOS_NO_RECEIVERS 11008 QoS no receivers. An established connection was aborted by the software in your host computer, possibly due to a data transmission time-out or protocol error. EMCASTFULL (121)Multicast table full.

WSAEPROTONOSUPPORT 10043 Protocol not supported. WSAEALREADY 10037 Operation already in progress. WSAENAMETOOLONG 10063 Name too long. However, that could easily be hours (or forever) after the socket fails.

Try temporarily turning off any firewall you are running.10052 - Network dropped connection on reset. Example Code (Note that this code uses " import socket " and thus all methods and all constants such as SOCK_STREAM must include the " socket. " preface. The table has room for 6 hosts. his comment is here This error could be caused by not enough DCUs being allocated (see CFG_NUM_PACKETS0 through CFG_NUM_PACKETS5), packets not being freed, or a task such as the IP task, is not getting a

Solution: Compare Client and Server configuration files Make sure that the DataPlus data sets specified in the Client's configuration file are also in the Server's configuration file. The service provider procedure call table is invalid. Error -9301 ("Incorrect Client/Server protocol (old version?)") This error might occur if the Client and Server have different release numbers (i.e.

When a particular Windows Sockets function indicates an error has occurred, this function should be called immediately to retrieve the extended error code for the failing function call.

It can also be returned by setsockopt if an attempt is made to set SO_KEEPALIVE on a connection that has already failed. WSA_QOS_GENERIC_ERROR 11015 QoS generic error. ETNOSUPPORT (141)Type not supported. ECONNREFUSED (107)Connection refused.

A database query failed because it was actively refused. EDHCPSERVBADRESP (601)Bad response from DHCP server. I've got the camera set to upload an image via FTP every second.  It's looking good! A call to the WSALookupServiceEnd function was made while this call was still processing.

A message sent on a datagram socket was larger than the internal message buffer or some other network limit, or the buffer used to receive a datagram was smaller than the WSA_NOT_ENOUGH_MEMORY 8 Insufficient memory available. This is a generic error code, returned under various conditions. EENTRYNOTFOUND (201)The host table entry was not found.

No more results can be returned by the WSALookupServiceNext function. So here is a simple-dummy example TCP client application which runs on either a PC or Digi product: It creates the socket It sets the socket timeout to 5.0 seconds, this This error is reported by xn_rtip_init if initialization of resources such as signals or semaphores, or spawning a task failed. The Client does not have to use every DataPlus set that is configured on the Server, but a data set must be on the Server before a Client can retrieve information

If you truly require detecting a TCP socket failure in 1 second or less, which implies your TCP peers normally send data many times per second, then use non-blocking sockets with When the server starts, a Process ID number is displayed on the screen. WSAENETUNREACH 10051 Network is unreachable. The output list size is limited by calling xn_interface_opt using IO_MAX_OUTPUT_QUE.

ERTNOTFOUND (136)Routing Table entry not found. Returned by WSARecv and WSARecvFrom to indicate that the remote party has initiated a graceful shutdown sequence. The protocol family has not been configured into the system or no implementation for it exists. 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

EAFNOSUPPORT (102)Family not supported. A retry at some time later may be successful. Users should check: That the appropriate Windows Sockets DLL file is in the current path.
