More unknown packet types...

04/26/2011 10:35 Lateralus#1

0x405/1029
0x408/1032
0x7FB/2043
0x7FC/2044
0x7FD/2045
0x800/2048
0x802/2050
0x803/2051
0x813/2067

All sent server->client. I found them with ollydbg, though I've encountered some on the japanese servers. I haven't done much research on these packets, and I'll probably follow up this thread with a request for unknown packets sent client->server. Any information about these types is appreciated, though the more, the better.

Also, what about subtypes of the general data packet - 0x67, 0x77, 0x7C, 0xCD, 0x3E8, and 0x3E9?

0x7FC/2044 - Offline TG (Enter, Time Remaining etc)
0x7FD/2045
0x7EE/2046 - Spawn NPC (Spawns the npc to the client)
0x7EF/2047 - Npc Click (Starts conversation with NPC)
0x800/2048 - Item Lock (Locks items etc)
0x802/2050 - Broadcast (Urgency etc)
0x803/2051
0x813/2067 - Mentor Packet (Claim Exp etc)

DataPacket:
0x67/103
0x77/119
0x7C/124
0xCD/205
0x3E8
0x3E9 - You sure this is general data?, cause 3E9 is also the create character packet

Those are mainly from memory, I don't really have any of my old documentation on the protocol anymore, I'll have a scan around my external drive soon as I have time.

Thanks! I have no idea why I included the NPC packets, I have those already. If you do happen to dig up the structures or subtypes, let me know. Here's what I've discovered with the general data subtypes, and yes, 0x3E8 and 0x3E9 ARE valid subtypes (I thought it was something wrong with my logger when I encountered them).

Unknown1 = 0x67, // 0xA3 on 4267.
Unknown2 = 0x77, // 0xAF on 4267. Not used? Links to a RETN.
Unknown3 = 0x7C, // 0xB8 on 4267.

^ Those subtypes above I truly have no clue as to structure and function, as I was working on a 4267 private server and those three subtypes were the only ones I didn't have documented and tried all I could.

// Was told by martin that it's something to do with the connection.
newUnknown1 = 0xCD,

/// <summary>
/// Sent server->client upon reviving Possibly spawns a character to other players; used as a screen update?
/// valueB = Xcoordinate, valueC = Ycoordinate, valueD = direction.
/// </summary>
newUnknown2 = 0x3E8,

// Looking at it through olly and tracing the call to the processing routine back, it seems to deal with KO's.
newUnknown3 = 0x3E9,

Code:

        public const Int16 Id = _MSG_UNKNOW1029;

        [StructLayout(LayoutKind.Sequential)]
        public struct MsgInfo
        {
            public MsgHeader Header;
            public Int32 Unknow1;
            public Int32 Param;
            public Int32 Unknow2;
        };

For the other packets, in all my sniff, I never saw them... But in EO source, they are referenced as:
2043: _MSG_AUCTION
2045: _MSG_ITEMATTRIB

PS. The specification of Haydz are good.

Ah thanks, it seems packet 1029 is sent not only when picking up amounts of gold larger than 1000, but when picking up all amounts. Looked at the processing of the packet in the client, and can't figure out the use of it.

1029 = media player, param to "opt media", opt to support the "play, broacast", "media" for the media file name
1032 = add an item to the card game players, game cards to delete a record

He's not asking for TQ's action types. :facepalm:

Oh, those are action types. No wonder I was so confused.

I seem to recall the 1029 packet had to be sent in order for the pickup money effect to be displayed, could be wrong but thats what springs to mind at the moment.

Korvacs maybe soon u can update ur wiki ? bcouse there is lots of changes in packets.

05/02/2011 13:49 shitboi#11

you can help to change it:p. It's not a lot of changes, just tiny changes here and there. Compare his documentation and the actual packet, you should easily figure things out.
