El script usa lo mismo que lo explicado en Comtrend hg536+: cambiar de ip sin resetear el router.
Podremos ejecutarlo siempre y cuando tengamos instalado python en nuestro SO (linux, windows ...). Podemos crear el archivo con el comando
cat > ~/bin/resetear.py
chmod u+x ~/bin/resetear.py
El script es el siguiente:
#!/usr/bin/python

# This scripts connect to router and reset ip in 40s. In this example use default values for jazztel .
