New User Registration Packet

[»Admiral Kirk]

Ok, trying to add New User Registration functionality to SubChat2. Ive gotten most of my information from MERVBot as far as the packets definition. Now, hop back a few packets, to the password Response packet. According to my do!@#$%^&*entation, the 19th byte is a boolean which should be 1 if the server is requesting a Registration Form. It seams that every time I login with an unkown user name I get the response code of 1 (unkown player) but the Registration Form Request byte is 0 (not requested) which is the same as it is when I login with an existing login name and get a response code of 0 (good login). Going beyond that, I just decided to send the Registration Form whenever I got a response code of 1, but the server seams to completely ignore it. I dont know if its because it didnt request it (no idea why it didnt) or if the Registration Data is malformed. Any information from anyone who has gotten the registration form to work would be GREATLY appreciated. Thanks in Advance.

Well, !@#$%^&*uming youre sending the password packet correctly, this is the code I used to handle the response:

 

case 0x0A:	// password packet response
			// Send Registration Information...
			if(objPacket.get(19) != 0)	{ this.sendRegistrationForm(SystemInfo.getName(), SystemInfo.getEmail(), SystemInfo.getCity(), SystemInfo.getState(), SystemInfo.getSex(), SystemInfo.getAge()); }

			// Re-send password packet if necessary...
			if(objPacket.get(1) == 1)
			{
				this.sendP!@#$%^&*wordPacket(true, this.objLoginInfo[0], this.objLoginInfo[1], SystemInfo.getMachineID(), SystemInfo.getTimeZoneBias(), SystemInfo.getPermissionID());
			} else {
				this.handleEvent(new LoginResponse(this, objPacket));
			}
		break;

That all looks right. Only problem is that Byte 19 never comes in as 1, even when I attempt to login with an unknown user name. Byte 1 does come back as 1 but Byte 19 is still 0. Here is my understanding of the password Packet

 

Offset	Length	Description
0		1		Type byte
1		1		Boolean: New user *1
2		32		Name
34		32		password
66		4		Machine ident *2
70		1		ConnectType *3
71		2		Timezone bias
73		2		?
75		2		Client version *4
77		4		? memory checksum, Set to = 444
81		4		? memory checksum, Set to = 555
85		4		Permission ident
89		12		?

 

And ya know... As im sitting here typing out this reply.. Mabye it has something to do with that New User Byte up thier in the password packet? Is that important? And if so, how might one determine if the user about to be logged in is a new user? Or should that bit be set on a subsequent password packet if we recieve a response of 1 (unkown user)?

Yess... Now I see. The first PW response comes with a response of 0x01 and reg of 0x00 then you send another PW packet with New User byte set, and then it response with a 0x00 and reg of 0x01. And I should assume it will come back with something other than 0x01 if the user name given is entirly illegal? Ok.. I think this is all making sense now, lets see if I can get it working ^^

Sweet! Works like a champ! Thanks Cerium!

[»Ceiu]

Yeah, sorry about that; I was half asleep when I replied.

 

Anyway, the first argument in my SendP!@#$%^&*wordPacket function is a boolean value for new user. Youve already got the rest figured out so...
