To verify the script is working correctly, try it out against a virtualized Wi-Fi network as follows: apt-get install vtun bridge-utils hostapd ./initradios.sh ./hostap0.sh # Start fist access point in window 1 ./hostap1.sh # Start second access point in window 2 Now read the documentation in `krack-ft-test.py`. Go to step 3 and start the tool using: sudo su source ../venv/bin/activate ../krack-ft-test.py wpa_supplicant -D nl80211 -i wlan2 -c supplicant.conf Follow the next steps. To generate traffic in step 5 use `./gen-traffic.py`.
