D2GS Packet Research

[Ringo]

Note; This research was done many years ago in a very short space of time.
- It has since been *refreshed* at 12th/jan/2010.



(Keep in mind my reserch was done in HC/SC ladder games)

So, Getting from the realm to game....

Responce to join request:
The last packet the realm sends you (with the game server info)

Code Select Expand

0000  15 00 04 03 00 C3 02 00 00 D5 F8 6A DB E2 BD C0    ...........j....
0010  0C 00 00 00 00                                     .....
15 00 - packet lengh
04 - Packet ID (MCP_JOINGAME)
03 00 - Request ID
C3 02 - D2GS Token
00 00 - 0x00
D5 F8 6A DB - D2GS IP
E2 BD C0 0C - D2GS Hash
00 00 00 00 - Result


Once connected to the game server, you should receve this:

Code Select Expand


S > C
AF 01                                              ..

In the above packets responce you will need to send some logon infomation to the game server.
The packet header is as follows for sending and recving(decompressed) packets:

Code Select Expand


(BYTE) Packet ID
(VOID) Data

The lengh of the packet is decided apone the packet ID and some/many packets have multiple formats/lenghs (this can be obtained from inside data values and in rare case's, inside packet lengh bytes)


As for sending logon info to the server:

Code Select Expand


C > S
68 D3 B0 B5 2C D9 03 04 0B 00 00 00 50 CC 5D ED
B6 19 A5 91 00 72 74 74 74 68 65 61 68 65 61 68
65 61 68 72 00

Clicky here and read the 1st packet in the list for infomation on sending this packet



Then if u get this packet its all good!
it means the game server has accepted you.
If u never recv this, it normaly can mean a few things, like failed to join game or say for example your proceeding data after ur char name wasnt right for your char)

Code Select Expand


S > C
02 5C                                              .\


Now the above packet has been recv, this packet should be sent to the server to enter the game enviroment.

Code Select Expand


C > S
6B                                                 k

After you have sent this, the server should then send you some very large clumped packets. (All the game infomation about you, other players etc)
You should notice that the large packets 1st byte does not match that of the packets lengh.
This is because most uncompressed packets have a lengh as the 1st byte.
This limits it to 240 as anything above that i used with a differnt method to obtain the uncompressed packets lengh (for decompression).
(Every packet from the server should be decompressed after u have sent this byte)
As for splitting the packets up, this is a matter of ones persional opinion, but you may want to keep chucking the clump of data back through ur parser, untill it comes to a unknown packet or parse's each message in the clump. But be warned, any bugs in your packet handlers will mess your whole parser up.

Here's a refrence to alot of the packets for ingame in a decompressed state if anyone wants it.

http://rumkin.com/software/diabloii/packets.php

[Ringo]

Nice
I notice alot of your recv are question marked as well, we should beable to make sence out alota this.

[edit] is that your reserch?

[Newby]

Very nice job.

[LordNevar]

No it is not my research, although I have put quite an extensive packet refrence like that together. It's rough but it works for what I need it for. I do not remember how I got my hands on that link, but it also serves it's purpose and maybe someone who really needs it can put it to a good use, and maybe identify alot more of it, and if Arta has the time and ambition could be added to a sub section of bnetdocs when it's more intuned.

[Ringo]

Iv got some notes all over the place, so i will put some more up tomorow.
I think alot of my notes were more based on figgering packets lenghs out, but i will also read through my parser, cos i expect that is more up todate than the notes iv just been reading through.
That link should proove very resourcefull and i will read through it tomorow to check for any errors in my notes, thanks.
This should at least get the ball rolling anyway

[QwertyMonster]

Wow Ringo, very nice job! I understand all of that

Edit: I suggest this being stickied or something, as its pretty usual.

[UserLoser.]

Don't forget about D2GS private messages (or whispers).  In a game, type @playername message, it has a different formatted chat messages

I'd love to help you out and do this all *again*, but I don't even have a client which can even connect to Battle.net anymore.  Only thing I have is SphtBot, well, I'd have to write a plugin to log onto realms then get back into D2 games...

[Ringo]

Thanks, i have added both other messages to the chat event packet but i didnt know of that @command, is there anymore like that?

If u generaly would love to help and have a set of d2 cdkeys still, id be happy to do a reinstall on them and send you the whole D2 folder - with d2loader
i think 1.5GB over msn would take awhile but if ur up for that idea then its ok with me.

I checked through some notes just now, and most of them i just dumped in txt's with nothing wrote with them so i will need to get my bot out and recatch them to get there values

UserLoser, how many(ish) packet IDs were there in the last patch? im guessing 100's 

[edit]
added a few more, but im outa time, iv got to go out, i will try do a few more tomorow if i get time.

[l)ragon]

Pretty sure the player id is marked as a byte with a value range of 0-7

[Ringo]

Pretty sure the player id is marked as a byte with a value range of 0-7

Hmm, this could have been one of the things that changed in the new patch, cos it seems everything is done via a 32bit value.

Players / town folks / gold / objects in general will have verying dwords for differnt games, and can change each time they go out of view.

Iv got a few things to do, but i got alot of packet dumps this morning, witch should be needed to sort alot more out, i will sort through abit of it later.

[l)ragon]

Can check if the death packet is still the same as this.
