Hello  I have troubles with D2GS_GAMELOGON packet.

After sending I'm not receive response from server...

What do I do not correctly?

My source:
[code]
printMsg("Send D2GS_GAMELOGON (0x" + PacketIDs.D2GS_GAMELOGON  + ") packet...");
Buffer b = new Buffer();
b.addByte((byte)PacketIDs.D2GS_GAMELOGON);
b.addDWord(d2gshash);
b.addWord((short)d2gstoken);
b.addByte((byte)0x04); // class
b.addDWord(0x0B);
b.addDWord(0xED5DCC50);
b.addDWord(0x91A519B6);
b.addByte((byte)0x00);
b.addNTString("DrugFree"); // name (null-terminated string)
b.addByte((byte)0x00); // unused byte 1
b.addByte((byte)0x00); // unused byte 2
b.addByte((byte)0x00); // unused byte 3
b.addByte((byte)0x00); // unused byte 4
b.addByte((byte)0x00); // unused byte 5
b.addByte((byte)0x00); // unused byte 6
b.addByte((byte)0x00); // unused byte 7

System.out.println("\n" + b);
d2gsOut.write(b.getBytes());
d2gsOut.flush();
[/code]

Hdx, thanks.

I not correctly read the d2gsHash from  S->С MCP_JOIN_GAME ...

I have correctly received d2gsHash and change a packet as you have told.
[code]
Buffer b = new Buffer();
b.addByte((byte) PacketIDs.D2GS_GAMELOGON);
b.addDWord(d2gshash);
b.addWord((short) d2gstoken);
b.addByte((byte) 0x04);
b.addDWord(0x0B); // version byte 0x0B
b.addDWord(0xED5DCC50);
b.addDWord(0x91A519B6);
b.addByte((byte) 0x00);
b.addNTString("DrugFree"); // name (null-terminated string)
b.addByte((byte) 0xb3);
b.addByte((byte) 0x6F);
b.addByte((byte) 0x4B);
b.addByte((byte) 0x00);
b.addByte((byte) 0x00);
b.addByte((byte) 0x00);
b.addByte((byte) 0x00);

Also has received the answer

But if to specify VersinByte 0x0C that of the answer will not be ... :[

Response  6 7a 9 2e ef 5c is correctly? I  read here (https://davnit.net/bnet/vL/index.php?topic=11756.0) that it should be 02 5C :(

My send 0x68
[code]

    pdBuf = HexToStr("00 00 00 00 8F D4 77 3A 18 AE 6F 4B 00 00 00 00")

  Form1.D2GS_PING = True
End Sub
[/code]
Possible Character IDs:
0x00 - Amazon
0x01 - Sorceress
0x02 - Necromancer
0x03 - Paladin
0x04 - Barbarian
0x05 - Druid
0x06 - Assassin
[code]
  Case &HAF:  Call D2GSsend0x68(hD2GShash, hD2GSToken)
    Case &H5C02
        If Len(data) = 2 Then
        Call D2GSsend0x6B
        Call D2GSsend0x6D
            D2GS_PING = True
            Exit Sub
        Else
[/code]

So if you get 02 5c response from server, just send 0x6B. with first ping packet

Purri, yes I get 02 5c, and send D2GS_ENTERGAMEENVIRONMENT and 0x6B  and d2g2_ping packets.

But, I have some questions...

What to specify in argument:
(DWORD) Tick Count in D2GS_PING packet? I specify const number 20 and send  every 6 seconds ...

After sending 0x6B packet the server sends me a very big quantity of data. How to parse they?

Thanks.

D2GS_PING DWORD you can use GetTickCount() function.

And after you send 0x6B and you get in game, all data is compressed, tbh AF 01 tells to client that next packets gonna be compressed.
