I'm sending everything successfully but I get no ping response back.

Here is my code:

[code]
import java.net.*;
import java.io.*;


public class bnetConnection{

    String host = "211.233.0.54";
    Socket skt = new Socket(host, 6112);
    String received;
    int id;

    BufferedReader myInput = new BufferedReader(new InputStreamReader(skt.getInputStream()));
    PrintStream myOutput = new PrintStream(skt.getOutputStream());
    buffer buff = new buffer();
   
 
   
    bnetConnection() throws Exception {
     
            myOutput.write(0x01);

    }
   
    public void send50() throws Exception{
     
        System.out.println("Connected to " + host);
        System.out.println("Sending Authorization");

        int verb = 0x0D;

       
        buff.addDWord(0);
        buff.addString("68XI");
        buff.addString("VD2D");
        buff.addDWord(verb);
        buff.addDWord(0);
        buff.addDWord(0);
        buff.addDWord(0);
        buff.addDWord(0);
        buff.addDWord(0);
        buff.addNTString("USA");
        buff.addNTString("United States");
        sendpack(0x50);
        System.out.println("Authorization Sent...");
        id = myInput.read();
        System.out.println("Received " + id);
       
       
    }
   
    public void Parseping() throws Exception{
       
        System.out.println("Got the ping");
    }

    public void Parsesend50() throws Exception{

        System.out.println("Got the packet 50 response");
    }

I'm using iagos buffer class with this which can be located here:
http://www.google.com/codesearch/p?hl=en#LCtTldHliGI/trunk/BNUBot/src/org/jbls/util/Buffer.java&q=buffer%20package:http://bnubot\.googlecode\.com&sa=N&cd=1&ct=rc


When i packet log this is what i send:

[code]

0080  00 00 00 00 00 00 00 00  00                        ........ . 

[/code]

Then i receive this:
[code]

0000  00 1b fc 69 78 a4 00 1a  70 d9 6e 5a 08 00 45 00  ...ix... p.nZ..E.

0030  6e 62 00 00 00 00 00 00  00 00 00 00              nb...... ....   


[/code]

And after send this out:
[code]
0000  00 1a 70 d9 6e 5a 00 1b  fc 69 78 a4 08 00 45 00  ..p.nZ.. .ix...E.

0040  17 e0 00 10 1b c3 05 00  00 00 74 65 6e 62        ........ ..tenb 
[/code]

Finally I get the last reponse bnet gives me:
[code]
0000  00 1b fc 69 78 a4 00 1a  70 d9 6e 5a 08 00 45 00  ...ix... p.nZ..E.

[/code]

1) NEVER access internal variables directly. They are public for a few specific reasons.
2) Use buff.Size() not buff.buffer.length you'll notice how there is a shit load of extra nulls at the end of your packet.
3) Its general practice to extend the Buffer class to make it protocol specific. See It overrides .GetBuffer() to add the packet ID/length to the data.

okay im using this now:  myOutput.write(buff.size() + 3);

also the only way to cut off the nulls at the end is if i go into the buffer class and change maxLength = maxLength * 2; to maxLength = maxLength + 1 in the verifyLength method.

Should I make that tweak in the buffer? Or will it interfere somehow.

Dont fuck with the buffer class, its perfect(tm)
Just use it properly.
.GetBuffer()
Like I said, DON'T ACCESS INTERNAL VARIABLES!

alright i successfully received packets 25 and 50 =D. Thanks a lot... lol I oversaw the methods that returned the length and buffer
