BeQuietDash!

BeQuietDash tries to catch the bootp/dhcp packet of an configured (it's better to not have an product selected) DASH-Button and sending it a configuration so it can't connect home to amazon. The DNS and Gateway will be set to its own IP.

Keep in mind that the Button can't connect to the internet. The timeout seems to be around 40 seconds before you can use the button again!

Compiling

$ gcc main.c -Wall

or if you want to see the raw bootp packages with debug

$ gcc main.c -Wall -DDEBUG

requirements

Nothing but gcc

using

$ sudo ./a.out

Output

Without debug

$ sudo ./a.out
