 Posted: Mon Feb 18, 2008 7:08 am Post subject: [DELPHI] Server emulation |
 |
|
hey everyone,
I'm pretty bored atm and I wanted to try to emulate the login server for MapleStory.
I use the client of OdinMS and simply added login.odinms.de to my host list that it connects to my localhost.
But before that, I recorded the packets of OdinMS when you open the client.
They aren't encrypted 
Here:

(logs are also added as WPE/TXT file in attachment)
And you see, the first packet is a packet you revice, so I thought the server will send this if the client connects.
So I started a new delphi project using TServerSocket.
But as what type should I send it a packet back? As String? Or the bytes as an array of bytes ?
thanks in advance

| I assume you would send it back as a string. The send() winsock function accepts a string, not bytes.

A packet when received/sended is always treated as an array of chars
I suggest you to write your own packets parser, wich has a list of packet and by looking at the command id (from what I've seen every packet you receive starts with a 3 digit id) it will bind the parameters

Oh okay thx to you both.
But I just noticed that there are only FTP IP's in the list (except one server Port: 20).
And asaf these are the common MapleGloabl FTP servers for as Irwin just told me in IRC:
| Code: | <Irwin> GameGuard FTP
<Irwin> Patch FTP
<Irwin> Movie FTP
<Irwin> ERL FTP |
But no IP of the actualy OdinMS login server which is 213.239.199.206 .
So I think it does just try to connect to it and if it didn't revice the first packet, it says "Server offline" or?

Thanks x0r. Wireshark is better than WPE.
I got it working now that the client at least connects to my "server"

| These are the "beggining packets" lol.. Those packets aren't encrypted untill you're getting to login screen.

reakw0n you are sending the wrong packets to open the client. I used net suspender to let me attached to odin before it sent any packets and heres what happens before the client opens. Only 2 packets, first 2 bytes, second 13.
| Code: | char bConnect1[] = {0x33, 0x00, 0x00,
0x00, 0x46, 0x72,
0x7A, 0x40, 0x52,
0x30, 0x78, 0x35,
0x08 };
char bConnect2[] = {0x0d, 0x00};
send(sd, bConnect2, sizeof(bConnect2), 0);
cout << "Sent" << sizeof(bConnect2) << " bytes to client." << endl;
send(sd, bConnect1, sizeof(bConnect1), 0);
cout << "Sent" << sizeof(bConnect1) << " bytes to client." << endl; |
