I'm getting this following error wlan0

[Hovak]

using: airmon-ng start wlan0
Above iwconfig shows that there exists wlan0
I have kali installed on termux shell

Did you run /usr/sbin/airmon-ng w/o any arguments to see the available devices the tool sees? I do see that you have wlan0 in your devices, but it's not seeing them.

Also, did you sudo up to root or are you logged in as root?

If you want root to use its env variables, you would want to 'sudo su -' from a normal user.

Sudo su in termux shell or kali bash?
Sudo is invalid in kali so should I install tsudo in termux?

 

[Hovak]

I have wlan0 see, now I don't know how sudo works in kali with termux

 

[Drizzit89]

Sudo won't work because you are root. sudo requests root to perform an elevated task on behalf of a lesser privileged user.
What phone did you install NetHunter on? Was it one of the officially supported devices?
Please list what is at /sys/class/net and provide listed devices.
