BackTrack 5 Gnome x64 : I can't launch airmon-ng !

Hello !

I have Backtrack 5 Gnome x64, and when I write "airmon-ng" in my Terminal to launch it, it's not ok ! Some programs keep running, like "dhclient3", and after, airmon-ng, it's not ok, yeah !

In the reality, I see this :

"Found 3 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
10681 dhclient3
10683 dhclient3
14167 dhclient
Process with PID 10683 (dhclient3) is running on interface wlan0"


Help me please !

Thanks in advance,

HLFH

I get this too. In BT RC2, you could turn the Network Service on and off to allow this to work. As I am fairly new to Linux, I am guessing this problem is due to the fact the Network Service is running but am not certain.

Could someone advise how to disable the Network Service as it is not in the services menu in BT5.

Thanks.

Hello !

Finally, you can try with the Terminal and "kill" or "killall" (and PIDs or names)...

But, at the end, it wasn't always ok for me on BackTrack 5 Gnome.

So, I will try BackTrack 5 KDE Version and I think it would be better.

Because, in BackTrack 4-R2, with KDE, it was great and wonderful for me ! ;)

Have you try killing the processes?

Yes, I tried ! And with success, I killed all the asked processes !

But finally, it wasn't efficient.

With Gnome, it's very difficult to launch easily Aircrack-ng&Co...

So, I try with success BackTrack 5 KDE x64 ;)

Hi to all,

I'm having same problem here, when I try to put my wlan0 to monitoring mode, I get message that there are processes that uses my wi-fi. I tried what airmon sugested, I tried to kill process dhclient, all but one can be killed, one is allways up and running. I have BT5 x64 with Gnome.

same here!bt5r2 gnome 64 and i cant succed to kill the last dhclient ..it always pops back up i tryed upstart-udev-bridge stop but still doesnt work.killall -9 just pops it back up and airmon-ng check kill same

Well kill the 3 processes, do it forcing it:

killall -9 dhclient3
killall -9 dhclient

or

kill -9 10681
kill -9 10683
kill -9 14167

Then bring down the interface (eth1, wlan0, etc): ifconfig "your iface" down
Change mac if needed: macchanger --mac 00:11:22:33:44:55 "your iface"
Change the mode to "monitor": iwconfig "your iface" monitor mode (if connecting to a network or using dhclient, need to change to managed mode)
then bring your iface back up: ifconfig "your iface" up

Now check if everything is ready: iwconfig

See info in your interface and check mode (should say "monitor")..Then just run airodump-ng "your iface"

Luck!!!

Following all steps above, airmon-ng is still asking to stop "dhclient" process which I'm not able to kill. Any suggestion?
