Airmon-ng start
To place our wlan0 wireless interface in monitor mode,
let’s execute Airmon-ng with the start option,
and the interface name.
Airmon-ng creates a new monitor mode interface named “wlan0mon”.
It appends “mon” to the interface name whenever possible;
some drivers don’t allow changing the interface name,
so it is important to take note of the resulting
monitor mode interface.
