Hi:

I am testing krack-test-clint.py but it doesnt work fo me :(.

I have TL-WN722NN v1. I have Kali 2017.1. I follow the instructions with the same order without succeful and of course I execute disable-hwcrypto.sh.

This is my currectly error, any idea?:

Thanks a lot Best Regards Perico

Today, I have another error. Please, anyone know a completly and good guide? I am trying test the app for the university but it is impossible that it works for me, always I have errors and I don't know why.

Thanks a lot

[ptdropper]

Hi PericoMele I found that I could disable the network manager by issueing the follwoing at the command line on my kali linux host: ifconfig wlan0mon down ifconfig wlan0 down nmcli networking off then proceed with the command ./krack-test-client.py You should end up with two devices listed by the ifconfig command: wlan0 wlan0mon

[DaniLuMa]

Thanks a lot ptdropper. It works very fine now. When I finish the test I will put a simple manual here for the rest of the people.

Best regards Dani

Hi:

This is a small guide to test your client wifi. I bought TL-WN722N v1 device but I will test it with anothers... I used Kali 2017.1.

1.- Install kali.

2.- Execute:

$ apt-get update $ apt-get install libnl-3-dev libnl-genl-3-dev pkg-config libssl-dev net-tools git sysfsutils python-scapy python-pycryptodome

3.- Clone krack-attack scripts

$ git clone https://github.com/vanhoefm/krackattacks-scripts.git

4.- Compile hostapd:

$ cd krackattacks-scripts/krackattack --> We are in "krackattacks-scripts/krackattack" directory $ pwd /root/krackattacks-scripts/krackattack $ cd ../hostapd $ cp defconfig .config $ make -j 2

5.- Disable hardware network

$ cd ../krackattack/ $ chmod 777 disable-hwcrypto.sh $ ./disable-hwcrypto.sh $ rfkill unblock wifi $ ifconfig wlan0mon down $ ifconfig wlan0 down $ nmcli networking off $ reboot

6.- Test client:

$ python2 krack-test-client.py

--> It will be waiting for connections to his own ESSID. It is "testnetwork" and psk is "abcdefgh". When you connect (with other device, not with this machine Kali 2017.1) the client you will see if your client has or hasnt the vulnerability in both, normal or group.

Best regards Perico

Could you show the output of these command right before running krack-test-client.py $ nmcli raio $ nmcli networking $ rfkill list wifi

What is the driver of your wifi card (check airmon-ng) ?. I have the same problem with you while using Intel wifi card.

[imoulas]

I have followed all proposed instructions. Netrwork card is TL-WN722N. Kali is updated. Kali is installed as a base OS on a MacAir laptop.

disable-hwcrypto.sh rfkill unblock wifi ifconfig wlan0 down ifconfig wlan1 down nmcli networking off reboot
