RE: [amsat-bb] Linux Predict Socket Server

["Dave Johnson" <g4dpz@xxxxxxxxxxxxxxx>]

Hi,

I've just got a simple client going which sends commands and
get the responses as in the c++ 'demo.c' NO error checking yet....

import java.io.*;
import java.net.*;

public class SocketTest {

  public static void main(String args[])
  {
      int port;
      InetAddress address;
      DatagramSocket socket = null;
      DatagramPacket packet;
      byte[] buf = new byte[256];

    try {

      if (args.length < 2)
      {
        System.out.println("Usage: java SocketTest <hostname> command
[sat]");
        return;
      }

      socket = new DatagramSocket();

      socket.setSoTimeout(1000);

      address = InetAddress.getByName(args[0]);

      String command = args[1];

      if (args.length == 3)
      {
        command = command + " " + args[2];
      }

      command = command + "\n";

      buf = command.getBytes();

      packet = new DatagramPacket(buf, buf.length,
                                           address, 1210);

      socket.send(packet);

      buf = new byte[255];
      packet = new DatagramPacket(buf, buf.length);
      socket.receive(packet);
      String outString = new String(packet.getData());

      System.out.println(outString);

    }
    catch(IOException e)
    {
      System.out.println("Error" + e);
    }
    finally
    {
      socket.close();
    }
  }
}

Now the fun begins......

I hope this sows a seed for other people..
