Okay. I need to know how to read packets (sry, excuse my newness). I need to know...
a) where to find and identify the packet [ i.e. 0x05 ]
b) how to find what is a dword, ntstring, etc.

This is a sample log I have taken, and I would appreciate it if you could analyze it and break it down, and show me how to read it.

You can easily find the answers to all your questions with just a little bit of effort on your part.

I don't see anything on reading packets...

I don't want to know about BNET packets, I want to know how to read packets in general.

a DWORD is any 4 bytes beside each other
a WORD is any 2 bytes
a BYTE is .. a byte.
a ntstring is any length of characters with a null (00) at the end

That's the most basic, how to convert a dword to a decimal number is a little different, but I'll let somebody else answer that.

OK, how would I identify the packet ID? i.e. 0x26

Would this be 0x1C? I saw the FF 1C, just a guess.

ALSO, Is there a program that will find the DWORDS, WORDS, NTSTRINGS, and all the other er uh 'things' :-p for me? I.e. it will analyze the data and say, "This is a DWORD", etc.

A program has no way of knowing what data type a packet is, unless of course it recognizes the packet.

What is so hard about this?

The BNet packet header is 0xFF PacketID(BYTE) Length(WORD)...
which makes 0x1C the packet id, 0x5F00 the length, and everything after that the data.

A DWORD is 4 bytes, following FF 1C 5F 00 there is a possible dword (4 bytes) [color=red]00 00 00 00[/color] which is displayed as [color=red]....[/color] in plain text format.

the first 4 bytes (FF 1C 5F 00) are the packet header
0xFF is always going to be the first byte in a BNCS packet
0x1C is the packet id
0x005F (in network order) is the packet length (including the packet header)

you want to look at the packet length (in this case, 0x5F is 95 in decimal), and count up that number of bytes
then, go to bnetdocs and look up s->c 0x1C
split up the packet based on the types


[code](Byte) FF
(Byte) 1C
(Word) 5F 00

(QWord) 00 00 00 00 00 00 00 00
(Word) 02 00
(Word) 01 00
(DWord) 1F 00 00 00
(DWord) 00 00 00 00
(NTString) 70 62 6F 74 74 65 73 74 69 6E 67 32 30 30 33 00 00 2C 34 34 2C 31 34 2C 36 2C 32 2C 32 2C 31 2C 36 32 30 65 33 63 31 33 65 20 4C 6F 73 74 20 54 65 6D 70 6C 65 0D 00[/code]

Thanks a lot for all your help!

[/quote]No, network byte order is just the opposite (big endian). Using network byte order for the Battle.net protocol is exactly wrong.
