Aide pour changer un message CRLF en STUN

Bonjours,

J'utilise un programme qui s appel ims bench.
C'est un injecteur de traffic. Il me permet d'envoyer des message keep_alive de type CRLF et je voudrai les mètre au format STUN.
Pour etre plus clair dans wireshark j'obtien le message suivant :
DATA : 0A0D0A0D //qui correspond a /r/n/r/n
[length : 4]

et moi je souhaiterai avoir en STUN
Message Type : 0X0001 (Binding Request)
Message Leng :
Message Cookie : 2112A442
Message Transsaction ID : 454E000025DECD0B3B320000

Pouvez-vous m'aider pour transforme de message?
Merci,

voila le code que j'ai. Ce qu'il me semble le plus important est entre les ///////////////

Code:

Salut,
RFC5389

J'ai récupéré sur le net http://www.codeproject.com/script/Ar...aspx?aid=23481

Je l'ai donc modifier pour pouvoir creer mon message stun.
Ma question est la suivante. j'ai 2 fichiers (user.cpp) et (stunHeader.cpp). Je voudrai récupérer mon message Stun (qui est crée dans le fichier stunHeader.cpp et le metre a la place de \r\n\r\n qui sont entre les ////// dans mon fichier user.cpp
Quesque je doit metre a la place de mes \r\n\r\n pour que lorsque je lance mon programme que les keep_alive soit au format STUN.
merci ,

voila donc le fichier stunHeader en question.

Code:
