Description of Issue My tcp client executes querying the tcp server one time successfully, returns the response, and then subsequent requests to the server from the client fails. Also, if i terminate the client and reload it fails on the first attempt as well. Here's what my command prompt looks like: root@ubuntuT:/home/jon/gocode/udps# ./udpservtcpclient Text to send: SampleQuery Message from server: SampleResponse Text to send: SampleQuery ((End - No Response)) root@ubuntuT:/home/jon/gocode/udps# ./udpservtcpclient Text to send: SampleQuery ((End - No Response)) What I expect I expect to be able to query the tcp server from the tcp client endlessly, and have the tcp server return a response from the UDP Server every tim...

Java Socket reading response from other application I'm currently making a connection from a software to an application using java socket. The code is more or less like this import java.io.*; import java.net.*; import java.util.Scanner; public class Input { public static void main(String args) { try{ Socket s=new Socket("ok",10003); PrintWriter printWriter = new PrintWriter(s.getOutputStream()); Scanner scanner = new Scanner( System.in ); BufferedReader inserver = new BufferedReader(new InputStreamReader(s.getInputStream())); String str = scanner.nextLine(); String hisscanner = "u0002"+str+"u0003"; printWriter.write(hisscanner); s.shutdownInput(); String response = inserver.readLine(); System.out.println("FROM SERVER: " + response); printWriter.close(); s.close(); scanner.close(); }catch (UnknownHostException ex) { System.out.println("Could not connect to the server [Unknown exception]"); } catch (IOException ex) { System.out.pri...

mongodb : listen() attempts to access socket in a forbidden way I downloaded 64-bit zipped version of mongodb for windows, created '/data/db' as instructed. Now, when I run "mongod" command, I am getting the following error & the mongodb server shuts down automatically. "ERROR : listen() failed error-10013. An attempt was made to access socket in a way forbidden by its access permissions. " Please help me to clear the firewall settings in windows to prevent this error & run mongodb. I was able to fix the error by using the following command : "mongod --bind_ip="127.0.0.1". :) – Dharshni May 18 '14 at 10:14 Perhaps better to put your comment in an answer and accept it. It can be useful to other users. – kranteg ...
