Nada de nada, sigue con lo mismo, mira no te rompas más la cabeza con eso, a lo mejor es una tufe de la maquina donde lo estoy probando.
Mira tengo a mano un script que me descargaron de Internet, que lo que hace es montar un servidor web con nc y por lo que he visto creo que hasta se pueden ver los directorios en dicho server, pero al ejecutarlo, me da unos errores de la opción -e del nc, que al parecer no esta implementada en el nc que tengo instalado en Linux, donde se puede conseguir una versión de netcat que venga con esta opción implementada o el source para compilarlo. el scrip esta interesante y raro, que es lo que mas me llama la atención.
en estos dias voy a subir a la wiki como crear un servidor web simple usando netcat
te lo dejo para que le tires un ojo a ver que me dices....
