I need to know is it possible..to make a app..to check if cod4 GUIDs was in use..without joining a server..
i've seen in php the fake players and the udp packet concerning the keycode in use error..
ie "\xff\xff\xff\xfferror\x0aEXE_ERR_CDKEY_IN_USE"

so is it possible to query the master server checking if any keycode is in use without using cod4?, joining a server..

it's the same protocol used in Quake 3 and so in my q3onlinekeybrute tool:
"\xff\xff\xff\xff" "getKeyAuthorize 0 YOUR_CDKEY_HERE"

packet sent to cod4master.activision.com:20800

the cdkey must be braketless, so must have a total size of 16 chars
CoD4 adds also a PB hash after the cdkey but it's not needed

for any doubt use a sniffer :)

Hey,

i used q3onlinecheck tool..changed the master server and port to cod4master.activision.com:20800

but it still says my keys are invalid...is there something more that needs to be changed?..

uhmmm check if the key is tranmitted in high case (ABCDEF and not abcdef).
anyway as already said before, get a sniffer and sniff what your game client sends so you will have an idea of a correct packet

that is easily done, made one for myself

it checks a single key via command line or the keys in a file line for line

results them as
1#cdkey - guid - inuse_state - pbban_status - publicbanlist_status
2#cdkey - guid - inuse_state - pbban_status - publicbanlist_status

in windows and writes a logfile, only thing i did not get to work properly was parallel checking without getting bad ordered responses for other key checked at the same time
all based on aluigi sources :D
