my aircrack-ng suite was working correctly until i updated to 15.04 i unsintal evrything and intsaled again form repositories to discard weird stuff and the problem is stil there:
sudo airmon-ng
Interface Chipset Driver
wlan0 Atheros AR9565 ath9k - [phy0]
kcdtv@profezorapplestruff:~$ sudo airmon-ng start wlan0
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
595 avahi-daemon
599 NetworkManager
678 avahi-daemon
749 wpa_supplicant
795 dhclient
Interface Chipset Driver
wlan0 Atheros AR9565 ath9k - [phy0]SIOCSIFFLAGS: Le nom n'est pas unique sur le réseau
(monitor mode enabled on mon0)
kcdtv@profezorapplestruff:~$ sudo airodump-ng mon0
ioctl(SIOCSIFFLAGS) failed: Name not unique on network
I tryed to habilitate and deshabilitate network manger etc...
the only walk around i found is to bring down the interface and activate mode monitor with iwconfig Which does not satisfy me. if i install aircrack-ng svn version i get the same fail but a more details in the shell:
kcdtv@profezorapplestruff:~$ sudo airodump-ng wlan0mon
[sudo] password for kcdtv:
ioctl(SIOCSIWMODE) failed: Device or resource busy
ARP linktype is set to 1 (Ethernet) - expected ARPHRD_IEEE80211,
ARPHRD_IEEE80211_FULL or ARPHRD_IEEE80211_PRISM instead. Make
sure RFMON is enabled: run 'airmon-ng start wlan0mon <#>'
Sysfs injection support was not found either.
My host file look like that
127.0.0.1 localhost
127.0.1.1 profezorapplestruff
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
and efectivly the device is til in managed mode:
/sbin/iw dev
phy#0
Interface wlan0mon
ifindex 4
wdev 0x2
addr 4c:bb:58:0f:ba:aa
type managed
Does anyone have a clue? thank you
edit solved with this trick! : Edit NewtorkManager.conf to prevent conflicts with airmon-ng (no check kill)
