From 645bbf2e0f6be1f9f4cc116dfc39939456b771e3 Mon Sep 17 00:00:00 2001 From: Stefan Knoblich Date: Sat, 17 Sep 2011 00:06:00 +0200 Subject: Parse broadcast arp responses via arping (iputils) properly ARP replies may/do contain two MAC addresses when using iputils's arping so we have to use the first one because it's always the "From" address - which is what we want. Thanks to Stefan Knoblich for the fixed pattern.
