iv been having problems trying to create a d2 game, specifically the problem occurs at the end of this sequence i wrote based on analysis of the real clients packets:-

(1) C-->S  0x03 (Realm)
(2) S-->C  0x03 (Realm)
(3) C-->S  0x04 (Realm)
(4) C-->S  0x1c  (Chat)
(5) S-->C  0x04 (Realm) - This contains the IP address of the D2 game server
(6) C-->S 0x22 (Chat) - Notify
(7) C-->S 0x10 (Chat) - LeaveChat
(8) Shutdown realm socket - (Real client appears to do this not sure why??)
(9) Connect to the D2 Game Server - (This is were the problem occurs the socket returns an error specifying that the server actively refused the connnection, the ip address seems ok that it's passing me i.e it's in the bnet servers range and i can ping it and get response and im not ip banned.)

I am a little puzzled by this to say the least i have checked and rechecked a number of times the procedure that the real client appears to use but no luck.

I dont know if any of you guys has done maybe some work on this procedure and could shed some light on the details and//or if im doing something wrong, btw before you ask i tried not disconnecting the realm before connecting to the D2GS and other combinations.

Also im assuming that the D2GS is tcp/ip and has a fixed port of 0xfa0.

Try sending 0x13 to the realm before leaving chat.  The packet contains no data.

Ok i tried sending 0x13 to the realm just before sending 0x10 (leaving chat) but it still refuses the connection

The thing is it sends the 0x04 response with the D2GS IP so i must be doing that part right so i cant understand why it's refusing the connection.

Anymore ideas?

Post a packet log of the connection (relevant packets) along with the IP address and port of the D2GS you are connecting to.

At the end of this sequence I shutdown the realm socket and attempt to connect to the D2GS server 213.248.106.92
using the fixed port 0xfa0, this then fails and returns a socket error after about 8 seconds specifying that "the target machine actively refused the connection".

well I almost have the same problem. When I connect to d2gs I cant get into the game due to me not sendin a packet I need to send to offically get into it. I do want to know why you disconnect the mcp socket

0x13 tells the server to cancel the game IIRC.  Don't send this and you should be fine.

hmm iv been told to try 0x13 to fix the problem originally, I could do with some consistant answers or ideas please.

I will say now sending 0x13 does not make any difference i still get the same socket error.

Surely someone must have done this procedure before i mean it's not that complicated except for the fact that the D2GS rejects the connection.

The reason i shutdown the realm socket is that if you watch the active connections the real client maintains once it creates a game it appears to close the realm connection and open a new one to the D2GS at almost the same time, of course i cant be sure of this but it certainly looks that way from my analysis.

Try leaving the connection to the MCP (realm) open.

No.  My client, and real D2 clients, send 0x13 after recieving 0x04 and before connecting to the game server.

Hmm, it's been a while since I've done anything relating to creating games in D2.

What makes you think so?  I've never actually done this, but reading this conjecture got me thinking.  If Windows is closing a socket and opening a new one to the D2GS, then it seems to me that the port numbers on your side would be different.  Honestly, that's the only thing I could think of (aside from differing SYN/ACK sequence IDs, I guess) that would tip me off to it being a different socket.

Hope that helps.

Please enlighten us with your knowledge of the protocol.

Seems no one on here knows how to do it//or wants to share their knowledge so ill try and hunt down some c++ source for it instead.
