# Horrible bodge for when ESP82xx devices are not responding to ARP requests any more.
# This script can run anywhere on the subnet. It listens for ARP requests and responds
# with the MAC address in macDict based on the IP address.
#
# Note that it will ONLY respond if the IP address is found in macDict below.
#
# Please be careful with this tool. If wrongly configured, network breakage could occur.
#
# Requires scapy (pip install scapy) and tcpdump. Running tcpdump usually requires root
# so this script will need to be run as root.
