# autoscan - automatic fingerprint of visited networks
# XXX IN PROGRESS 20130721 laurent
# 2013, Laurent Ghigonis <laurent@gouloum.fr>
# Usage: autoscan.py [interfaces]
# by default, monitor all network interfaces
# Each time network connectivity become available after a cut-off,
# run some tests and store results in a file db
# * ifconfig
# * if WIFI, iwconfig
# * route -n
# * traceroute
# * local net IP scan
# * public IP (curl ifconfig.me)
# * ping 8.8.8.8
