airmon-ng error

When i type:

Code:

---

airmon-ng start wlan0 6

---

i get this error:

Code:

---

wlan0 iwl3945 - [phy0]/usr/local/sbin/airmon-ng: line 338: /sys/class/ieee80211/phy0/add_iface: Permission denied
mon0: ERROR while getting interface flags: No such device

(Monitor mode enabled on mon0)

---

Why i get this error?

Thanks

Try:

Code:

---

iwconfig

---

Then show us what you get from that.

if wlan0 .... that means you have not start ipwraw-ng driver

the driver you are currently using is not capable of monitor mode

so unload it / load the right one....

don't use airmon-ng at all with this card

you will get 2 interface wifi0 on wich you change channel & rate

and rtap0 on wich you monitor

Actually, the file /sys/class/ieee80211/phy0/add_iface does not exist.
I mean, if i type ifconfig, i get my wifi mac adress and i can see wlan0 exists, i know i have a wifi interface working.
