	baos.write(this.major); // Param 2 (Major)
	baos.write(this.minor); // Param 3 (minor)
	baos.write(this.build); // Param 4 (Build)
	baos.flush();
	byte[] data = baos.toByteArray();
	System.out.println(Arrays.toString(data));
}
When you are using
Code:
baos.write();
you are writing bytes directly to the byte array instead of the real int, short, bool, whatever.

For example, major, minor and build must be integers (1 int == 4 bytes) instead of using 4 bytes for that variable you're using only 1.

Also you're missing the whole packet structure which is:
Code:
2 bytes => packet length
2 bytes => packet ID

*VARIABLE FOR EACH PACKET*
Then you've to take a look into the packet class (the 'answer' of VersionRequest has ID 667). If I'm not wrong the correct structure for that one was:
Code:
2 bytes => length
2 bytes => packet ID (667)
4 bytes => major
4 bytes => minor
4 bytes => build
1 byte  => that boolean
Try using DataOutputStream (example):
Code:
public void SendVersionResponse() throws IOException {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    DataOutputStream os = new DataOutputStream(baos);

    os.writeShort(15);       // If my awesome maths aren't wrong 2+4+4+4+1=15 (Packet Length)
    os.writeShort(667);      // Packet ID
    os.writeInt(this.major); // Param 1 (Major)
    os.writeInt(this.minor); // Param 2 (minor)
    os.writeInt(this.build); // Param 3 (Build)
    os.writeBool(true);      // Param 4 | True or Flase (1/0)
    
    byte[] data = baos.toByteArray();
    YOURSOCKETOBJECT.getOutputStream().write(data, 0, data.length);
    YOURSOCKETOBJECT.getOutputStream().flush();
    System.out.println(Arrays.toString(data));
}
Hope it helps!

Regards.-

But as Requi said, I bet the problem is on the param order. As I wrote in the example I think the bool was the last param instead of the first one. I can't remember the packet structure right now and I'm 3lazy to decompile main now.

3. (int) Major. // Should be the same one that client sends you in packet 666.
4. (bool) Server agrees that version. // Should be true.
5. (int) Minor. // Should be the same one that client sends you in packet 666.
6. (int) Build. // "

hmmm it's not work :/ the client cancel connection to the Server, why ? I have no idea... hmmm

The order of the parameters can change.

Kannst mir mal einen gefallen tun und den Code Deobfuscator mit rüber jagen lassen wenn du schon jpexs nutzt. Dann kann man den code um einiges besser lesen.

thx for the tip

here ^^

      }
      
      public function write(param1:IDataOutput) : void
      {
         param1.writeShort(ID);
         this.§_-8z§(param1);
      }

         param1.writeInt(this.build);
         param1.writeBoolean(this.§_-p3q§);
      }
   }
}

and my Response from Server:

Code:

public void SendVersionResponse(Socket clientSocket) throws IOException {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        DataOutputStream os = new DataOutputStream(baos);
        os.writeShort(15);
        os.writeShort(667);
        os.writeInt(this.major);
        os.writeInt(this.minor);
        os.writeInt(this.build);
        os.writeBoolean(true);

        byte[] data = baos.toByteArray();
        clientSocket.getOutputStream().write(data,0, data.length);
        clientSocket.getOutputStream().flush();
        clientSocket.getOutputStream().close();
        System.out.println(Arrays.toString(data));
    }

RESULT:

Code:

Dein DataOutputStream macht irgendwas falsch:

Code:

[0, 15, 2, 155, 0, 0, 0, 0, 0, 0, 0, 87, 0, 0, 0, 7, 1]

ist wie das bytearray aussehen muss. Ein byte geht von 0-255. Ein byte kann nicht negativ sein.

Hi!

I've decided to start (or continue) a private server. It will be hosted on github so everyone on this section can take a look and contribute (I'll be accepting pull requests).

It will have 2009 client and a custom CMS design.

If you want to contribute:

The CMS is on branch cms
The emulator is on branch emulator
The database is on branch master
Read README.md on branch master for more info

If readme files aren't enough you can find me on the discord server or through my skype

This is the repository:

See you!

HammerTyrs22 · 06/13/2016, 11:23

Hey Guys, i have a question ,
how can find the response packet to a Requestpacket ?

I have from the client the Packet ID = 10966 , how is the Response ID ? and Where find this ?

Reverse engineering, there isn't a magic way to get them. Find the command handler and continue from there, most of the times is extremely easy.

Good luck!

someone can give me the source of DarkEmulator v2 whit cms ??

Look how the client initializes and handles slotmenus.

hello I'm back here as long as I showed in the forum, I hope you are all right :-)

I'm working on my private server project that does not release any training for two years now working there alone quietly (do not try it sun aide).

or changed many things new new new maps laser companies, many events alien ships, items that will be programmed automatically during the week.

(They will design new iris)

There will be many beautiful things I brought to the emulator version 6.5.0.0 with automatic restart every 15 hours.
I am now working on java and flash player version 4.9.3.

best regards YURI-ELIADE.ITALY

BlaXi17 · 07/10/2016, 18:44

When did u planned on releasing it?

Nommo · 07/25/2016, 16:30

Hello!
I am trying to revive my node.JS DO server project and Im stuck at sending other users ships info.

My packet looks like:

Code:

sock.write('0|C|' + id + '|' + value['shipid'] + '|3|' + value['clantag'] + '|' + value['username'] + '|' + value['x'] + '|' + value['y'] + '|' + value['company'] + '|' + value['clanid'] + '|' + value['rank'] + '|0|' + diplo + '|' + value['galaxygatesdone'] + '\0');

Ofc all datas from Object are correct..
It shows red square insted of ship. TAG/Name/Rank/GG etc. works perfectly. Maybe theres some kind of files problem? It is based on 2008 client.

Regards,
Nommo.

I dont know your program, but do you need that null terminator at the end?
