A just-for-fun script for Amsterdam Airport Schiphol Public Wi-Fi network

The other day I got stuck in Amsterdam Airport Schiphol for more that 10 hours due to a flight delay. I was very disappointed. "Will work from here" - I decided. Once I connected to public Wi-Fi spot a message welcomed me stated that access would be limited to 30 minutes per device :( I didn't give up and wrote this small script that would reset mac address and would reconnect to the desired Wi-Fi network automatically every 30 minutes. I hope it can be useful for someone else.
