Weird error

When I log in using W2BN, battle.net doesn't respond to SID_ENTERCHAT unless I send another packet after it.

For D2DV/D2XP/WAR3/W3XP I've got the bot set up to send SID_JOINCHANNEL after recieving the SID_ENTERCHAT response from battle.net, and that works just fine. Is it safe to assume that the server will always respond immediately to SID_ENTERCHAT?

Leaky

o.O as far as i've ever noticed it does...

why dont you try sending a b and c at the same time? instead of waiting for a to come back?

Camel

You can't join a channel until after you've entered chat. My bot depends does some pretty complex stuff that depends on the response of SID_ENTERCHAT, and if for some reason the server responded out of order, it could cause unknown problems.

Of course, it's extremely rare for that to happen, but I've seen it before.

Does anybody know how the official client behaves? I haven't even got a working copy of Windows right now, so I can't look at it.

Leaky

i'd help you out but i dont have wc2.. do you see the issue on sc?

Camel

No idea; I never bothered to try to get SC working because of warden.

Barabajagal

All OLS clients (DRTL/DSHR/W2BN/SSHR/JSTR) send 0x0A, 0x0B, and 0x0C in that order all at once.

Leaky

that's what i said o.O

Camel

Well then I'll just have to hope I never recieve SID_ENTERCHAT late.

Barabajagal

I'm just telling him you're right. BTW, I've updated some of the logon sequences, but apparently linking and formatting isn't yet allowed in documents *cough*.

The official clients send the 0x0A and 0x0C in the same function, you can also send the 0x0B (you must, however, in war3/w3xp) after the 0x0A and before the 0x0C. It must be in this order always. Battle.net enforces this with an IPBan for late packet sends.

Scio te esse, sed quid sumne? :P

Barabajagal

I made a mistake. Diablo II Sends 0x0B before 0x0A or 0x0C apparently.

Leaky

andy are you sure? as far as i know all clients send a b c in that order...

I'm working on getting the order of all the clients, and I just did D2XP Open and it was B A C.
