Package: aircrack-ng
Version: 1:1.2-0~beta3-4
Severity: important

Dear maintainer,

When I use airmon-ng I get the following error:

viktor@jessie$ sudo airmon-ng start wlan1

Found 5 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!

PID     Name
693     NetworkManager
705     avahi-daemon
736     avahi-daemon
782     wpa_supplicant
794     dhclient
Process with PID 794 (dhclient) is running on interface wlan0

Interface       Chipset         Driver

wlan0           Broadcom        wl - [phy0]
wlan1           Atheros AR9271  ath9k - [phy2]SIOCSIFFLAGS: Name not unique on

                                (monitor mode enabled on mon0)

Then when I want to do airodump-ng this happens:

viktor@jessie:~$ sudo airodump-ng mon0
ioctl(SIOCSIFFLAGS) failed: Name not unique on network

I have found a workaround here:

First, you have to bring the interface down
sudo ifconfig wlan1 down

Then put it into monitor mode:
sudo iwconfig wlan1 mode monitor

Then bring it up:
sudo ifconfig wlan1 up

You can use airodump-ng now:
sudo airodump-ng start wlan1


The usb adapter is OK, i tested it on another computer which has Kali Linux
and it worked without problems.
