Sorry, but i put it in spanish, my first lenguage (i speak english too bad), if anyone want, he can tranlate to english.
Code:
Hola.
En primer lugar, me despido. Dejo el lineage 2 creo que para siempre. No he estado mucho en este foro, pero he aprendido mucho.
En segundo lugar publico el codigo de un sniffer que empece, pero nunca acabe
Esta escrito en c#, en concreto voy a publicar la parte de desencriptar los paquetes, que es la que mas que costo hacer:
(Consegui desencriptar tanto el loginserver como el gameserver, el login es mucho mas dificil)
empezamos por el login:
Primero hay que desencriptar el init packet, que es el primero que envia el GS

pero con una pequeña modificacion al final.El resto de paquetes del loginserver los puedes desencriptar usando la clase bfc y la clave que viene en el init packet, puedes hacer Init.getBlowfishkey();
Los paquetes del gameserven son mas faciles, el codigo ya estaba por internet, y ahora no me apetece buscarlo...
bueno pues eso... me despido... pero si alguien nesesita ayuda de algo que me pregunte.
