# This script launches `eaphammer` tool by s0lst1c3, available from:
# https://github.com/s0lst1c3/eaphammer.git
#
# The tool is a great way to manage hostapd-wpe server as well as perform
# additional attacks around the concept. Although when used in penetration
# testing assignments, the tool may not be as reliable as believed due to
# various nuances with WLAN interface being blocked, not reloaded,
# DHCP-forced and so on. This is where this script comes in - it tries to
# automatize those steps before launching the tool and after.
#
# Especially handy when used with companion script called:
# `initDHCPServer.sh`
