I keep getting ip ban after i send the packet. I really don't know what is wrong there! I hope you guys can help me fixing this problem. I made a new Thread with all new informations because it seems no one looks into the old thread. Thanks guys

you're getting a response of 0x200 which is "Invalid CD Key". should be self-explanatory.

My BNLS Response is correct. You can see how I send the packet. If I would know where the problem is i wouldn't ask :|

He's not saying your BNLS response is incorrect. He's saying your CD-Key is incorrect. Maybe you left out a number/letter from your CDKey, or made a typo and mistakenly put in the wrong letter/number into the cdkey? Basically, you need to look at your CD key. Try testing your cd key with stealth and see if it works. If it works, then the problem here probably is on how you're hashing your cdkey for submission to BNLS.

You also need to know that regardless of how you set up your cdkey hash, BNLS will not catch errors in your hashing-- as long as the packet is set up correctly, BNLS will not catch errors in the hash, and will calculate its response based on the hash, even if the hash is incorrect.

I just noticed.. I am grabbing the ServerToken from the wrong position .. It must be BNET.ServerToken = *(DWORD*)&data[8]; gosh ..
