0x63 (Arranged Team Invite)

[iNsaNe]

Hey guys, I'm having a bit of trouble with accepting / sending arranged team invites.
(http://forum.valhallalegends.com/index.php?topic=6205.0)

I have made the bot so that it can invite players and accept invites, but every time the bot accepts an invite or the user accepts the bot's invite I get the error from battle.net: "The team game you attempted to join could not be found..." and the inviter gets the firewall message.

I'm sending the port (e0 17, 6112) which I use to connect my bot with. I also use that same port with Warcraft 3.
Any help would be appreciated

I'm sending the port (e0 17, 6112) which I use to connect my bot with. I also use that same port with Warcraft 3.

This is a completely wild guess, and I've never worked with this packet before, but aren't you supposed to htons() the port ?

I'm not sure, this is the first time I've worked with this packet as well. In the packet logs I've seen e0 17 a bunch so I don't think you have to

are you sending the packet in UDP? i think it should be sent in UDP not TCP. i could be wrong.

Warcraft 3 uses TCP.

im noticing something different when im packet logging. When you are in the "Arranged Team Lounge" (lol) the packet headers begin with f7 instead of ff. Am i wrong?

Instead of replying with a normal ff 63 do i reply with an f7 1e? they seem to have the same structure

f7 1e is just like:

Code Select Expand

(DWORD)     Cookie
(DWORD)     Host random token value?
(BYTE)      0
(WORD)      Host port
(DWORD)     not sure
(STRING)    Host name
(DWORD)     not sure
(DWORD)     not sure
(DWORD)     5
(DWORD)     0
(BYTE)      0

laugh at me if you want, im no researcher.

0xF7 begins the WC3 in-game header, just as 0xFF does for BNCS messages

the structure is similar to BNCS,

Code Select Expand


(BYTE)    0xF7
(BYTE)    Message ID
(WORD)    Message length (including header)
(VOID)    Message Data

Do you have a TCP socket setup listening and accepting incoming connections?  If not, that may be why it says "game not found"

Code Select Expand

(DWORD)     Cookie
(DWORD)     Host random token value?
(BYTE)      0
(WORD)      Host port
(DWORD)     not sure
(STRING)    Host name
(DWORD)     not sure
(DWORD)     not sure
(DWORD)     5
(DWORD)     0
(BYTE)      0

The last 16 bytes are a sockaddr_in struct that you will need to pass on to any clients (via 0xF706) if you are the game host.
