    Java socket

    I am trying to open a socket and send a
    query to a remote comp. It connects allright, but does not
    respond to the query, not even with an error message - that's
    the problem.

    just fyi - the ultimate goal of this program is to find mashines
    within given IP range and read their parameters (hostname, mac
    address, etc.)

    Thanks a bunch!

    try {
    input = new BufferedReader(new
    InputStreamReader(System.in));
    OutputStream out = socket.getOutputStream();

    out.write (45);
    System.out.println ("start reading");
    BufferedReader din =
    new BufferedReader(new InputStreamReader
    (socket.getInputStream()));
    System.out.println ("done creating object");
    response = din.readLine();
    System.out.println ("done reading");

    System.out.print (response);
    socket.close();
    //}
    }
    catch (IOException e) {
    System.out.println(e);
    }

    Question tried the URL class??

    have you tried the URL connections?
    It will open a connection, then you'll have to request the rest once it's opened. it takes a full http://www.blah.com/
    url argument at the command line
    ----------------------------------
    import java.io.*;
    import java.net.*;

    public class Url {
    public static void main(String args[]) {
    boolean conn=true;
    for (int i = 0; i <args.length; i++){
    try{
    URL u = new URL(args[i]);

    try{ URLConnection uc = u.openConnection();
    InputStream in = uc.getInputStream( );
    } catch (IOException e) {
    conn=false;
    }

    }catch (MalformedURLException e) {
    conn=false;
    } //end first try
    } //end for

    if (conn)
    System.out.println(conn);
    else
    System.out.println(conn);
    }
    }
