Creación de Exploits 1 por corelanc0d3r

[rafael_lior]

Buenas dias, estuve leyendo el manual de creacion de  exploit de corelancoder, del capitulo me quede en ingresar una shellcode para ingresar por via telnet. sin embargo no me funciona abre el puerto pero cuando intento ingresar por putty a ese servicio telnet. no puedo.

¿Has comprobado el log del servicio a ver si aparece algún error?

Justamente estaba pensando que er tema de idioma del S.O , porque para las pruebas uso un Windows XP SP3 en Español, sin embargo el exploit esta en Ingles, cuando lo cambie de idioma, me seguia presentado el mismo error, a pesar de que se abrio el puerto 4444, en modo listening, por lo que yo creo es que me falta habilitar el telnet y asi pueda ingresar , No estoy seguro con mi teoria. Espero un apoyo. Gracias.
