Hello,

when I start the script, and a client connects I immediately get the following error: [14:21:34] 50:eb:71:f8:e8:eb: 4-way handshake completed (RSN) Traceback (most recent call last): File "./krackattacks-scripts/krackattack/krack-test-client.py", line 625, in <module> attack.run(options=options) File "./krackattacks-scripts/krackattack/krack-test-client.py", line 485, in run if self.sock_mon in sel[0]: self.handle_mon_rx() File "./krackattacks-scripts/krackattack/krack-test-client.py", line 354, in handle_mon_rx iv = dot11_get_iv(p) File "/home/zsolt/krackattacks-scripts/krackattack/libwifi.py", line 154, in dot11_get_iv payload = str(p[Dot11Encrypted]) File "/usr/local/lib/python2.7/dist-packages/scapy/packet.py", line 1171, in __getitem__ raise IndexError("Layer [%s] not found" % lname) IndexError: Layer [Dot11Encrypted] not found [14:21:34] Closing hostapd and cleaning up ...

Does anyone has any idea how to solve this? I'm stuck here, and found no solution anywhere. I am using Kali Linux 2020.2.

Thanks in advance!

Never mind, figured it out.

Hi kampi85, glad that you figured it out. Can you post what went wrong, in case others face the same issue?

mugiwara85 commented 4 years ago

Hi, of course. I did the almost the same thing as Gabba90 described here: https://github.com/vanhoefm/krackattacks-scripts/issues/71#issuecomment-533591576 I replaced scapy 2.4.3 with an older version 2.4.0. The only difference was, that I didn't use the command apt-get install python-pip but rather pip uninstall python-pip Now everything is working fine.

@mugiwara85 Hi Can you mention the WiFi Adapter and driver version that you used with krackattack script.
