Here is a dump:
Code:
Client -> Server: 1100 ~ 52
34 00 4C 04 0A F6 83 01 30 38 30 30 32 37 30 30 45 30 31 45 ;4.L..??.08002700E01E
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ;....................
00 00 00 00 00 00 00 00 00 00 00 00 ;............
Client -> Server: 1052 ~ 28
1C 00 1C 04 0A F6 83 01 0B 00 00 00 72 65 73 2E 64 61 74 00 ;.....??.....res.dat.
00 00 00 00 00 00 00 00 ;........
So I have no clue what the first packet does (44C), but apparently the second one (NOTE: this is happening on the auth server and not the game server) has 2 ints and 1 string:
unkown:int(4)
value from file res.dat:int(8)
string "res.dat": string(12) |
They aren't really new packets, they've always existed, just the packet types have changed around. (iirc).
The first one (44C), contains the two tokens (key1, key2) and the 12 character string your seeing there is your MAC Address. I couldn't really tell you what this does specifically as it's not referenced in EO and I don't have any co binaries to reverse.
The second (41C), has the structure of:
Code:
ushort MsgSize;
ushort MsgType;
uint AccountID;
uint dwData;
string szInfo[16];
and basically just sends the integer contained within res.dat (afaik this was one of the methods they used to determine whether you had patched to 4351 back in the mysticmerchant days).
