[Solved] rPi 4 wlan0 monitor mode does not output any packets
Hi All,
Running Kali on rPi 4.
I have configured my rPi 4 wlan0 interface to be in monitor mode:
└─$ sudo iw dev
phy#0
Unnamed/non-netdev interface
wdev 0x2
addr xx:xx:xx:xx:xx:xx
type P2P-device
txpower 31.00 dBm
Interface wlan0
ifindex 3
wdev 0x1
addr xx:xx:xx:xx:xx:xx
type monitor
channel 1 (2412 MHz), width: 20 MHz, center1: 2412 MHz
txpower 31.00 dBm
In the Wireshark GUI, I select wlan0 but get no packets showing.
Likewise, running tcpdump shows nothing.
└─$ sudo tcpdump -i wlan0 -v
tcpdump: listening on wlan0, link-type EN10MB (Ethernet), snapshot length 262144 bytes
Any ideas as to why this is?
Additional details:
- I am connected to the rPi over VNC via Ethernet as I am running a headless system.
- Is it possible that I cannot run eth0 and wlan0 at the same time?
Thanks, Randy
Strange ...
Notice that the wlan0 state is DOWN. However, I forced it up with before running the ip command:
Maybe you can't have both eth0 and wlan0 active at the same time.
EDIT: My rPi is not connected to any AP via WiFi, so ...(more)
