How to get it onto your Raspberry Pi 3 B+​

On a Linux desktop and Windows desktop:

  1. Insert your MicroSD to your PC
  2. Use BalenaEtcher software to write the img file to your MicroSD card's. [https://www.balena.io/etcher/]
  3. Insert the SD Card into your RasPi and wait for it to boot - it will show up as kali

Note: Make sure that the MicroSD (once flashed by Etcher) has an empty file called ssh on it - this will enable the SSH remote access. I ran into the problem that the root access did not work for me. So I had to use the kali user.

Login​

Default Logins:

UsernamePassword
roottoor
kalikali

After using the kali login I can change the default root login and re-login with that:

ssh kali@192.168.2.48
kali@192.168.2.48's password: kali
sudo su
passwd root

And allow the root login:

nano /etc/ssh/sshd_config

by adding the following line:

#PermitRootLogin prohibit-password
PermitRootLogin yes

After restarting the SSH service you will now be able to remotely login using the root user with your personal password:

/etc/init.d/ssh restart

Change the IP Address​

sudo nano /etc/network/interfaces

Deactivate the DHCP service and add your static IP configuration:

auto lo
iface lo inet loopback

auto eth0
allow-hotplug eth0
# iface eth0 inet dhcp
iface eth0 inet static
  address 192.168.2.113
  netmask 255.255.255.0
  gateway 192.168.2.1
  dns-nameservers 192.168.2.1

Restart the networking service and login again on your new IP address:

systemctl restart networking.service

Change the Hostname​

Set new hostname:

hostnamectl set-hostname server1

Edit the hostfile to resolve your new hostname to localhost:

nano /etc/hosts

127.0.0.1       server1    localhost

And verify that the hostname was set successfully:

hostnamectl

Static hostname: server1
         Icon name: computer
        Machine ID: 068a7d772bd446b79607eb8f3fe0ac6b
           Boot ID: db0592c1953f4c9489312c7caa3e38f4
  Operating System: Kali GNU/Linux Rolling
            Kernel: Linux 5.4.83-Re4son-v7+
      Architecture: arm

Trying Airmon-NG​

I was having some difficulties getting the Broadcom WiFi into monitoring mode. I tried several things and one of them - or a combination of them - finally enabled me to capture WiFi packages:

Trying Airmon-NG

Here is a list of steps that I took:

Activating Monitoring Mode for the main WiFi Board​

ifconfig wlan0 down
iwconfig wlan0 mode monitor
ifconfig wlan0 up

The second step above failed with the following error message:

Error for wireless request "Set Mode" (8B06) :
    SET failed on device wlan0 ; Device or resource busy.

The following command helps you to kill all processes that might be using wlan0:

airmon-ng check kill

This killed the wpa_supplicant service and I continued masking this service and rebooted the pi:

systemctl mask wpa_supplicant.service
reboot

Starting the monitoring service​

airmon-ng start wlan0

This gave me an error message:

ERROR adding monitor mode interface: command failed: Operation not supported (-95)

This is a bug can be solved by reloading the Broadcom driver:

rmmod brcmfmac
modprobe brcmfmac

Afterward I was able to start the service:

airmon-ng start wlan0

And the monitoring interface was now listed:

airmon-ng

PHY     Interface       Driver          Chipset

phy1    wlan0           brcmfmac        Broadcom 43430
phy1    wlan0mon        brcmfmac        Broadcom 43430

Starting airodump-ng to display the captured packages​

This command lead me to the screenshot above:

airodump-ng wlan0mon

Verify that it is working​

To make sure this wasn't a fluke I rebooted my Pi and ran the following commands:

airmon-ng start wlan0
airodump-ng wlan0mon

And it worked - this time without any complaints!
