The arp solution merely looks for the thing trying to get on the network by testing that is has a unique MAC address. Which is fine, but it requires additional software, vs. iptables which is definitely going to be there on a router.<div class=""><br class=""><div class=""><div><blockquote type="cite" class=""><div class="">On Jul 24, 2016, at 9:43 AM, Rodney Radford <<a href="mailto:ncgadgetry@gmail.com" class="">ncgadgetry@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">Perhaps I am missing something, but how is the arpalert and the scapy solution different - aren't both looking for and reacting to the ARP requests as the dash button comes on?<div class=""><br class=""></div></div><div class="gmail_extra"><br class=""><div class="gmail_quote">On Sun, Jul 24, 2016 at 8:58 AM, Alex Davis via TriEmbed <span dir="ltr" class=""><<a href="mailto:triembed@triembed.org" target="_blank" class="">triembed@triembed.org</a>></span> wrote:<br class=""><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><br class="">

good call on avoiding scapy and arp request sniffing. How about just blocking it with iptables and logging something, then having a daemon process watch the log for the entry, at which point you can run whatever you want. I really don’t like the idea of the buttons phoning home to Amazon anyway.<br class="">
