Get information about WiFi networks around you using Aircrack on Ubuntu or Kali Linux.


Getting information about wireless networks on Linux using Aircrack is very easy. This is a way to listen for Wi-Fi Access Points around you with a Wi-Fi USB adapter.

Firstly, run this command as root to put the Wi-Fi interface into monitor mode.

┏jcartwright@jcartwright-System-Version╼╸╸╸╸╸╸╾
┗━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━◉:~$ sudo airmon-ng start wlx90de80d9ed01
sudo airmon-ng start wlx90de80d9ed01
 
Found 4 processes that could cause trouble.
Kill them using 'airmon-ng check kill' before putting
the card in monitor mode, they will interfere by changing channels
and sometimes putting the interface back in managed mode
 
    PID Name
   1636 avahi-daemon
   2093 avahi-daemon
   2330 NetworkManager
   2333 wpa_supplicant
 
PHY	Interface	Driver		Chipset
 
phy0	wlx90de80d9ed01	rtw_8822bu	Realtek Semiconductor Corp. 802.11ac NIC
		(monitor mode enabled)

Then, run this command to listen for all Wi-Fi networks around you, this will show any SSID instances that do not have names as well as hidden SSID instances.

┏jcartwright@jcartwright-System-Version╼╸╸╸╸╸╸╾ ┗━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━◉:~$ sudo airodump-ng wlx90de80d9ed01

Running airodump-ng like this to get any client BSSID addresses.

sudo airodump-ng --bssid AC:B6:87:D3:CB:2B wlx90de80d9ed01

This was successful and I managed to see one client on the Wi-Fi network.
