I have looked around for this but can only find minor details about this packet. I cant get on d2 since i keep getting the packet 0x4a what should i reply with? I did a packet log on d2 it gets the 0x4a but nerver sends 0x4b if i just try to ignore the packet with my bot I get an ipban.

Not much of a 'botmaster' eh? ;)

If you do a forum search on 0x4A you'll find all the information you need to know about handling it.

that is the only thing I can find on 0x4A

and it shows you what is in the data but you can disable sending it. Like you can with diablo II and it really does not talk about that at all.

You can choose to ignore it, but can't stop Battle.net from sending it to you.

and by ignoring it i just dont reply with 4b right? if that is the case how come I am still getting an ipban o.O

If HKEY_CURRENT_USER\Software\Battle.net\Optimize\SysDesc is set to 1, then some game clients such as Starcraft will respond to this while logging on. What you're supposed to do is download the required file (usually IX86ExtraWork.mpq), extract the DLL from it, call ExtraWork(), and send the results back to Battle.net

How would we go about extracting the dll?
