Example use case to use packetfu to get basic iface information.

iface_summary.rb

require 'packetfu'

# iface becomes the default routeable interface
iface = PacketFu::Utils.default_int

# config will determine the ifconfig data for iface
config = PacketFu::Utils.ifconfig(iface)

# print out some of the relevant information
puts "      iface: " + config[:iface]
puts "mac address: " + config[:eth_saddr]
puts "   local ip: " + config[:ip_saddr]

# => example output ...
#       iface: en0
# mac address: t0:0s:1l:ly:4y:0u
#    local ip: 10.0.0.10
