YIM Packets

[Jaquio]

Alright, wasn't sure where to post this, but since it's general programming figured I would post it here..

I was wondering if anyone has any documentations for Yahoo Messenger Packets, preferably the new YIM. I have packet logged myself connecting an whatnot but can't make heads or tails from the log.. Was just wondering if anyone did have it... Or knew where I could find one, have tried google an found once for C/C++ but I am gonna do this in VB.

When I first connect to the server, I recieve nothing.. So I guess I have to send something first? Who knows, I have tried sending everything.. No idea what to do.


So yea, any ideas would be really great.. Thanks.

Well it did a bit.. But some of that I already know.

See what I am looking for is something like.. Uhh.. Hmm.. Something close to BNet Docs on the YIM Protocol if it's anywhere possible to find one.. If not I guess I will have to try an do it myself? Lol, Because I logged on using an exact packet log from a previous logon an it worked.. But I wanna know like, where a dword,word or byte goes.

I don't know I guess I will eventually figure it out, thanks again.

BnetDocs was built by people with some free time and a good base of general programming/networking knowledge.  If you want to make YIMDocs, I'm sure a lot of people would be greatful and offer what help they can.

[edit]
You can also look at Gaim's source code.

Hmm, not a bad idea to make a YIMDocs, or even a IMDocs(For all instant messenger protocols.) would be a nice project to get going. Not sure how many people would actually wanna help, or if it would even be helpful to anyone. But I am willing to try anything, if anyone wants in starting tomorrow I will be on AIM,YIM an MSN if anyone wants to talk.

AIM: CyberJaquio
YIM: bjmoreton.at.yahoo.com
MSN: bjmoreton.at.gmail.com

An if you want you could just email me at bjmoreton.at.gmail.com I have a webserver an everything for another site, so a webpage for it all would be already to go. An I am a great PHP Scripter so making scripts to store/view all the information would be an easy task for me. So yea, if anyone wants in just holla at me tomorrow.


I will also be currently trying to get around to figuring out YIM Connection sometime tonight, if I get anywhere I will post it.

[MyndFyre]

Why don't you try out a Wiki such as MediaWiki?  With good organization, I think a wiki format would be even better than BnetDocs (such as my super-secret WoW protocol Wiki)

[Jaquio]

What would it take for me to get acccess to your 'super-secret WoW protocol wiki'? But I have thought about it, but I love coding, so I could put something together that'll do that same an that I could change around if needed, I use other peoples scripts sometimes if I know how they work. But without knowing how they work, or what function an whatnot is where makes it kinda hard to update/add things onto it.

But yea.. I have gotten nowhere with the YIM Protocols.. Stupid thing!


I did however find these some help on the matter just not alot since I can't really make since of it..
         The other parts had nothing to do with the actual protocol it's self really, only these ones had good information.

Apparently it all came from here Yahoo Coders Cook Book.


I think I understand it sorta.. Not sure though will have to try tomorrow going to bed now..

That site looked fine. Should be all you need. Well, that and a few packet logs of your own.

[Jaquio]

scs.yahoo.com = not connecting. So therefore I can't do anything, the way the messenger connects is how I am trying to do it. Here is a packet log for the connection up until buddy list which I am not showing.

If anyone cares to tell what is going on there.. It would be a big help to me.. >_<

[Joe[x86]]

If you want BnetDocs style documentation, here you go:

NSTD Data Types:
YSTRING - Raw string followed by C0 80

Packet Header:
(DWORD)   Client Type       (Constant: 59 4D 53 47)
(WORD)    Protocol Version  (Constant: 00 0B)
(WORD)    NULL              (Constant: 00 00)
(WORD)    Message Length    (Variable: Message length minus header length)

YIM_AUTH_INFO
(BYTE)    NULL              (Constant: 00)
(BYTE)    Challenge Command (Constant: 'W')
(DWORD)   Identifier        (Constant: 00 00 00 00)
(BYTE)    Logging In        (Constant: 30)
(YSTRING) UNKNOWN           (Constant: "1")
(YSTRING) Yahoo Username    (Variable: duh)

General rules of thumb:
A TAYSTE is a 2-bit unsigned little endian integer (one fourth byte)
A NYBBLE is a 4-bit unsigned little endian integer (one half byte)
A BYTE is an 8-bit unsigned little endian integer (one byte)
A WORD is a 16-bit unsigned little endian integer (two bytes)
A TWORD is a 20-bit unsigned little endian integer (three bytes)
A DWORD is a 32-bit unsigned little endian integer (four bytes)
A QWORD is a 64-bit unsigned little endian integer (eight bytes)

Of course, the C-types corresponding with these names depend on the processor architecture. A WORD will be 16-bit on a 16-bit system (the Windows 3.1 days), 32 on a 32 bit system (most common), and 64 on a 64-bit system (newer processors).

Of course, the C-types corresponding with these names depend on the processor architecture. A WORD will be 16-bit on a 16-bit system (the Windows 3.1 days), 32 on a 32 bit system (most common), and 64 on a 64-bit system (newer processors).

Which is why you should always #include <inttypes.h> and use the more appropriately named {,u}int{8,16,32,64}_t types.   Whoever thought defining WORD to a set size that would never be changed really wasn't thinking very far ahead...

[Jaquio]

Alright, I figured it out some what.. Kinda to what Joe said, this is the format.

4 Bytes - Header(Always YMSG)
2 Bytes - Version(00 0E currently)
2 Bytes - Uknown(Always 00 00)
2 Bytes - Data Length
2 Bytes - Service Type
4 Bytes - Status
4 Bytes - Session ID

Anything after that is data being the length of the 2 byte data length.


What I am trying to figure out.. Is how to tell if there was a failed logon.. I have packet logged myself doing both.. A good logon an a failed logon(Using the wrong password). But nothing in the packets seem to change.. An I get nothing back after that packet.. Here they are maybe someone else can help?

Any idea why their pretty much the same?

[raylu]

Correct me if I'm being retarded...but version seems to be 00 00, not 00 0E...

[Jaquio]

Correct me if I'm being retarded...but version seems to be 00 00, not 00 0E...

For some reasons.. On client-sent packets you have to put 0x000E or it don't go through. On server-sent packets, they usually don't include the version for some reason. It's not always 0x0000 on server-sent though, sometimes it is 0x000E.

[raylu]

Hm...the first (significant) difference I see is at byte 39...

It looks something like a BNCS checksum to me...there are no more packets after this?
