Hm, just to warn you, this will be a long post  ::)

As the title said, I send 0x50 to bnet and get bs back. The "bs" is "-1-1-1-1" ... and on when I print the data out as ints, and "?????????" ... when I print it out as chars. I'm trying to narrow down what could be wrong. First of all, here is my 0x50 packet:
[code]
public class SidAuthInfo extends PacketBuffer {
public SidAuthInfo() {
super((byte) 0x50);             
    insertDword((byte) 0x00);                // protocol id
    insertNonNTString("IX86");        // platform ID
    insertNonNTString("PXES");        // product ID
    insertDword((byte) 0x00);                // product language
    insertDword((byte) 0x00);                // local ip
    insertDword((byte) 0x00);                // time zone bias
    insertDword((byte) 0x00);                // locale id
    insertDword((byte) 0x00);                // language id
    insertNTString("USA");            // country abbrev.
    insertNTString("United States");  // country name
    }
}
[/code]

Is there anything wrong with this? Secondly, here are my packet buffer and packet classes:
[code]
public class PacketBuffer extends Packet {

public PacketBuffer() {}
   
    public PacketBuffer(byte packetheader) {
        super(packetheader);
    }
   
    public PacketBuffer(Packet data) {
        super(data);
    }
   
    public PacketBuffer(byte[] rawdata) {
        super(rawdata);
    }
   
    public void insertWord(int value) {
        insertByte((byte) ((value >> 8) & 0xFF));
        insertByte((byte) (value & 0xFF));
    }
   
    public void insertDword(int value) {
        insertByte((byte) ((value >> 24) & 0xFF)); 
        insertByte((byte) ((value >> 16) & 0xFF)); 
        insertByte((byte) ((value >> 8) & 0xFF));
        insertByte((byte) (value & 0xFF));
    }
   
    public void insertNonNTString(String str) {
        byte[] strbytes = str.getBytes();
        insertBytes(strbytes);
    }
   
    public void insertNTString(String str) {
        byte[] strbytes = str.getBytes();
        insertBytes(strbytes);
        insertByte((byte) 0x00);
    }
}
[/code]
[code]
public class Packet {

private Vector buffer = new Vector();
protected static final int WORD = 2;
protected static final int DWORD = 4;

    private byte packetheader;
   
    public Packet() {}
   
    public Packet(byte packetheader) {
        this.packetheader = packetheader;
    }
   
    public Packet(Packet data) {
        insertBytes(data.getRawData());
    }
   
    public Packet(byte[] rawdata) {
        insertBytes(rawdata);
    }
   
    public void insertByte(byte element) {
        buffer.add(new Byte(element));
    }
   
   
    public void insertBytes(byte[] elements) {
        for (int i = 0; i < elements.length; i++)
            buffer.add(new Byte(elements[i]));
    }
   
    public byte getByteAt(int index) {
        Byte temp = (Byte)buffer.get(index);
        byte returnbyte = temp.byteValue();
        return returnbyte;
    }
   
    public byte[] getRawData() {
        byte[] packet = new byte[buffer.size()];
        for (int i = 0; i < buffer.size(); i++) {
            Byte temp = (Byte)buffer.get(i);
            packet[i] = temp.byteValue();
        }
        return packet;
    }
   
    public byte getPacketHeader() {
        return packetheader;
    }
}
[/code]
Thirdly here is the class I created to test all this out. (Warning: long).
[code]
public class Login {

// Packets
Packet sidAuthInfoSnd;
Packet sidPing;
Packet sidAuthInfoRcv;

// IO stuff
private BufferedReader reader;
private Socket sock;
private InputStream in;
private OutputStream out;

// command stuff
private char trigger = '/';
private enum Commands { CONNECT, DISC, QUIT }

public Login() {
Packet buff = new PacketBuffer();

reader = new BufferedReader(new InputStreamReader(System.in));
System.out.println
("COMMANDS:" + "\n" +
"/CONNECT to connect" + "\n" +
"/DISC to disc" + "\n" +
"/QUIT to exit program" );

while (true) {
String text = null;
try {
text = reader.readLine();
}
catch (IOException e) {
System.out.println("ERROR!");
}

if (text != null && text.charAt(0) == trigger && text.toCharArray().length > 2) {
char[] chars = text.toCharArray();
char[] temp = new char[chars.length - 1];
for (int i = 0; i < temp.length; i++) {
temp[i] = chars[i + 1];
}
String cmd = new String(temp);

switch(Commands.valueOf(cmd.toUpperCase())) {
case CONNECT:
System.out.println("Connecting...");
connect();
break;
case DISC:
System.out.println("Disconnecting...");
disc();
break;
case QUIT:
disc();
System.exit(0);
default:
System.out.println("No Command.");
}
}

}
}

private void connect() {
// create IO objects
try {
sock = new Socket("useast.battle.net", 6112);
in = sock.getInputStream();
out = sock.getOutputStream();
}
catch(IOException e) {
System.out.println(e.toString());
}

sidAuthInfoSnd = new SidAuthInfo();
try {
out.write(sidAuthInfoSnd.getRawData());
}
catch (IOException e) {
System.out.println(e.toString());
}

sidPing = rcvPing();
byte[] ping = sidPing.getRawData();
for (int i : new int[ping.length]) {
System.out.print(ping[i]);
}
System.out.print("\n");
seeRcvAuthInfo();

}

private void disc() {

}

private Packet rcvPing() {
Packet buff = new PacketBuffer((byte) 0x25);
for (int i = 0; i < 4; i++) {
try {
buff.insertByte((byte)in.read());
}
catch (IOException e) {
System.out.println(e.toString());
}
}
return buff;
}

private void seeRcvAuthInfo() {
Thread t = new Thread(new Runnable() {
public void run() {     
//-------
// after not rcving for 5 secs I seal packet
try {
sock.setSoTimeout(5000);
}
catch (SocketException e) {
System.out.println(e.toString());
}

//-----
//place the stuff I rcv into packet
Packet buff = new PacketBuffer((byte) 0x50);
boolean rcving = true;
while (rcving) {
try {
byte input = (byte) in.read();
buff.insertByte(input);
System.out.print((char)input);  // just to see what i'm rcving as i'm rcving it
}
catch (SocketTimeoutException timeout) {
System.out.println("TIMEOUT!");
rcving = false;
}
catch (IOException e) {
System.out.println("ERROR RECEIVING SidAuthInfo");
break;
}
}
//---------
//disable timeout
try {                         
sock.setSoTimeout(0);
}
catch (SocketException e) {
System.out.println(e.toString());
}
//-------
//print out packet
byte[] data = buff.getRawData();
for (int i = 0; i < data.length; i++) {
System.out.print(data[i]);
}
}
});
t.start();
}

/**

public static void main(String[] args) {
new Login();
}

First, your SID_AUTH_INFO packet format is incorrect.
[quote](DWORD) Protocol ID (0)
(DWORD) Platform ID
(DWORD) Product ID
(DWORD) Version Byte
(DWORD) Product language
(DWORD) Local IP for NAT compatibility*
(DWORD) Time zone bias*
(DWORD) Locale ID*
(DWORD) Language ID*
(STRING) Country abreviation
(STRING) Country[/quote]
You have forgotten the version byte. The current one is 0xCD
Second:
[quote][code]    insertNonNTString("IX86");        // platform ID[/code][/quote]
Should be:
[quote][code]    insertNonNTString("68XI");        // platform ID[/code][/quote]
But you should really be handling them as the DWORDs they are.

The -1's that you're receving are indications that there were errors on the socket.

Hdx, thanks for the corrections, I realize you are right about those things. I'm still getting -1-1-1-1 from bnet when I print it out as ints. I implemented the packet header, btw, and the game protocol ID at the start. Here are the revisions to my Login and SidAuthInfo classes:

[code]
public class Login {

// Packets
private Packet sidAuthInfoSnd;
private Packet sidPing;
private Packet sidAuthInfoRcv;

// IO stuff
private BufferedReader reader;
private Socket sock;
private InputStream in;
private OutputStream out;

// command stuff
private char trigger = '/';
private enum Commands { CONNECT, DISC, QUIT }

public Login() {

Packet buff = new PacketBuffer();

reader = new BufferedReader(new InputStreamReader(System.in));
System.out.println
("COMMANDS:" + "\n" +
"/CONNECT to connect" + "\n" +
"/DISC to disc" + "\n" +
"/QUIT to exit program" );

while (true) {
String text = null;
try {
text = reader.readLine();
}
catch (IOException e) {
System.out.println("ERROR!");
}

if (text != null && text.charAt(0) == trigger && text.toCharArray().length > 2) {
char[] chars = text.toCharArray();
char[] temp = new char[chars.length - 1];
for (int i = 0; i < temp.length; i++) {
temp[i] = chars[i + 1];
}
String cmd = new String(temp);

switch(Commands.valueOf(cmd.toUpperCase())) {
case CONNECT:
System.out.println("Connecting...");
connect();
break;
case DISC:
System.out.println("Disconnecting...");
disc();
break;
case QUIT:
disc();
System.exit(0);
default:
System.out.println("No Command.");
}
}

}
}

private void connect() {
// create IO objects
try {
sock = new Socket("useast.battle.net", 6112);
in = sock.getInputStream();
out = sock.getOutputStream();
}
catch(IOException e) {
System.out.println(e.toString());
return; // don't try to connect if there are no IO objects
}

//------
// Send protocol ID (0x01 = game protocol)
try {
out.write((byte) 0x01);
}
catch (IOException e) {
System.out.println("Unable to send protocol ID");
}

sidAuthInfoSnd = new SidAuthInfo();
try {
out.write(sidAuthInfoSnd.getRawData());
}
catch (IOException e) {
System.out.println(e.toString());
}

sidPing = rcvPing();
byte[] ping = sidPing.getRawData();
for (int i : new int[ping.length]) {
System.out.print(ping[i]);

seeRcvAuthInfo();

}
catch (IOException e) {
System.out.println(e.toString());
}
}
return buff;
}

private void seeRcvAuthInfo() {
Thread t = new Thread(new Runnable() {
public void run() {     
//-------
// after not rcving for 5 secs I seal packet
try {
sock.setSoTimeout(5000);
}
catch (SocketException e) {
System.out.println(e.toString());
}

//-----
//place the stuff I rcv into packet
Packet buff = new PacketBuffer();
boolean rcving = true;
while (rcving) {
try {
byte input = (byte) in.read();
buff.insertByte(input);
System.out.print((char)input);  // just to see what i'm rcving as i'm rcving it
}
catch (SocketTimeoutException timeout) {
System.out.println("TIMEOUT!");
rcving = false;
}
catch (IOException e) {
System.out.println("ERROR RECEIVING SidAuthInfo");
break;
}
}
//---------
//disable timeout
try {                         
sock.setSoTimeout(0);
}
catch (SocketException e) {
System.out.println(e.toString());
}
//-------
//print out packet
byte[] data = buff.getRawData();
for (int i = 0; i < data.length; i++) {
System.out.print(data[i]);
}
}
});
t.start();
