Network Socket Connection Error
For TCP sockets, options argument should be an object which specifies: port: Port the client should connect to (Required). Event: 'error'# Added in: v0.1.90
WSAESERVERUNREACH (10065) The server is unreachable. Indeed, the only time that nonblocking I/O is not the optimal solution is when you also need to detect timeouts on connect operations, or when your target environment does not support The last parameter callback will be added as a listener for the 'listening' event. Length-prefixed and delimited systems may send empty messages (e.g., a length prefix of “0 bytes” or a single “end delimiter”).
How To Fix Socket Error
If exception is specified, an 'error' event will be emitted and any listeners for that event will receive exception as an argument. I'm pasting the very slightly modified (IP and port numbers are different) Beej's C code for Server side and Client side here: Server.c /* ** server.c */ #include
- For network clients, this is the easiest solution and offers simpler, more manageable code.
- socket.destroy([exception])# Added in: v0.1.90 Ensures that no more I/O activity happens on this socket.
- About allowHalfOpen, refer to createServer() and 'end' event.
- The following example shows a connection request:// Connect to a remote server by hostname, with a four second timeout Socket connection = TimedSocket.getSocket("server.my-network.net", 23, 4000); If all goes well, a socket
- The 'close' event will be called directly following this event.
- This can be checked by running netstat -n on Windows Server 2003 and Windows XP or by running netstat -b on Windows Server 2003 as described above.
- If the handshake fails then it indicates that there are problems and the server is not listening, consequently there will be no connection.
A socket error can occur if one or more of the above conditions are not met or something is blocking communication between the client and server (e.g. server.domain.com). For more error code information, refer to Knowledge Base article 10140 at http://kb.globalscape.com. No Connection Could Be Made Because The Target Machine Actively Refused It With only a few lines of code, you can incorporate timeout supports for any socket application.
If you continue to receive the same error after insuring ports 20 and 21 are open, contact the administrator of the site you are trying to connect to. Our Commenting Policies
