It could also be a timing issue. I suggest you post your (cut-down) code. 10038 (WSAENOTSOCK): Socket operation on nonsocket. An operation was attempted on something that is not a socket. Either the socket handle parameter did not reference a valid socket, or for select, a member of an fd_set was not valid. share|improve this answer answered Oct 16 '10 at 8:34 Mitch Wheat 214k28345442 1 downvoters please leave a comment. –Mitch Wheat Jan 30 at 0:00 Can you explain the cryptic: "An operation was attempted on something that is not a socket" –Silvester Aug 11 at 8:53 add a comment| up vote 6 down vote I bet you are accessing a socket that you already closed. This is a very common timing bug in WinSock programming - the good news (and bad news, because it's hard

The master sends request to the slave and the slave in response send to the master the data cyclically. This data send cyclically by the slave is 1000 bytes per 0.5 msec. When the masters makes the request to send the data, on the console an error is reported. " socket error code Select() function error code:: 10038 ". This is the code for WSAENOTSOCK. This application is a single threaded application receiving the data from the slave. As from the error it seems that the socket is closed before it is checked by the select function. Can any one please point me in the direction ? :::Source Code:::: int Receive() { int rc; socklen_t cli_alen; struct timeval to; fd_set read_fd, write_fd, excep_fd; FD_ZERO(&write_fd); FD_ZERO(&excep_fd); sock_again: if (!_isSocketOpen) { return 0; } FD_ZERO(&read_fd); FD_SET(_sock_fd, &read_fd); to.tv_sec = 0; to.tv_usec = 0; cli_alen = sizeof(SOCKADDR_IN); rc = select(_sock_fd+1, &read_fd, &write_fd, &excep_fd, &to); if (rc == 0 ) { // Timeout // printf("XCP Port %d : select() timded out \n", _port); acess = 1; goto sock_again; } else if (rc == SOCKET_ERROR) { // Error LogError("XCP: select() error %d", WSAGetLastError()); closesocket(_sock_fd); return -1; } else { // Data if (!FD_ISSET(_sock_fd, &read_fd)) { LogError("XCP: select() wrong socket descr"); return -1; } else { //read data rc = recvfrom(_sock_fd, (char *)_recvBuf, UDP_RECVBUFLEN, 0, (LPSOCKADDR)&_saddr, &cli_alen); } } } :::: Edited :::: int CloseUdpConnection() { if (closesocket(_sock_fd) == SOCKET_ERROR) { LogError("closesocket() error: %d", WSAGetLastError()); return -1; } _isSocketOpen = 0; LogError("successfully closed socket %s:%d", _address, _port); return 0; } ::::: Debug Trace ::::: xcpApplication.ex
SyncBackFree,use a different FTP engine and so return less cryptic error messages. Article Detail When testing an FTP connection you may receive one of the following errors: Socket Error # 11001, Host not found: Check that the hostname or IP address has been entered correctly. Socket Error # 11004, Unable to connect: Check to make sure there isn't a trailing or leading space character on the FTP hostname. Also, enter the hostname or IP address, not a URL, e.g. if you have entered something like ftp://my.hostname.com/ then change it to my.hostname.com Socket Error # 10061, Connection refused: The hostname is correct, but either the FTP server is not listening on the port, there is no FTP server running, or a firewall is blocking the connection. Socket Error # 10093: This can happen when the network connection goes down, e.g. the FTP server is no longer connected to the network. Socket Error # 10038: If you are using Serv-U modify your FTP server settings so that the following are unticked: “Block anti time-out schemes”, “Block FTP_bounce attacks and FXP”, and “Block users who connect more than 6 times within 60 seconds for 30 minutes.”. You may also want to be sure you are using a passive connection. Socket Error # 10039: There may be a problem getting the IP address for the hostname. Socket Error # 10052: The host you were connected to crashed and rebooted. Try reconnecting at a later time. Unable to connect: Connection time out: The hostname may be incorrect or the FTP server may be behind a firewall. Unable to connect. Not logged in: The username and/or password is not correct. Unable to connect. Error connecting with SSL: The FTP server does not support SSL, or you are using implicit SSL and it only supports explicit, or the wrong port number is being used. If you are using implicit SSL then you probably need to use port 990 instead of port 21. When running a profile that connects to an FTP server you may receive the following errors in the log file: Scan failed (-1): Read Timeout: The connection to the FTP server was lost, and the attempts to reconnect failed, while trying to scan it for changes. Other common problems are: Can connect to the FTP server but when trying to choose the destination directory nothing happens for a very long time. Eventually the selection window appears but it’s empty: You need to enable Passive mode, or the FTP server is behind a firewall that is not configured correctly. Please note that many routers will intercept FTP commands and change them to try and help with the connection. This is
