I am new to ubuntu os.I have installed aircrack successfully and trying to execute the command sudo airodump-ng mon0
but its not working.How to fix this issue ?
Error:
ubuntu@ubuntu:~$ sudo airmon-ng start waln0
Found 4 processes that could cause trouble.
If airodump-ng, aireplay-ng or airtun-ng stops working after
a short period of time, you may want to kill (some of) them!
