Siocsifflags error : Name not unique on network problem

Hi everyone,

I've installed Arch successfully, and i am trying to learn about network security. I used aircrack-ng to hack my own WEP and WPA2 router.
I managed to use airmon-ng, airodump-ng and wifite without any problem on Kali Linux booted as Live USB.
This what it returns when I run 

airmon-ng
 Interface       Chipset         Driver

wlp5s0          Intel AC        iwlwifi - [phy0]
wlp0s26u1u2             Unknown         rtl8192cu - [phy1]

However, when I run

 airmon-ng start wlp0s26u1u2

it will returns 

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

351     wpa_supplicant

                                (monitor mode enabled on mon0)

and when I run 

 airodump-ng mon0

it will returns

 ioctl(SIOCSIFFLAGS) failed: Name not unique on network

I've tried method suggested in this thread but it still doesn't work.


The output of 

hostname

is 

divingpigeon

My /etc/hosts looks like this:

#<ip-address>   <hostname.domain.org>   <hostname>
127.0.0.1       divingpigeon
::1             localhost.localdomain   localhost

i have also tried 

#<ip-address>   <hostname.domain.org>   <hostname>
127.0.0.1       localhost.localdomain      divingpigeon
::1             localhost.localdomain   localhost

but still it doesn't work.

iwconfig returns:

lo        no wireless extensions.

And when I try using wifite, it will looped at 'choose wireless interface to put on monitor mode', in which it will keep adding monitor interface(mon0,mon1,mon2,mon3 and so on).

I have also tried to manually set the interface to monitor mode using

ifconfig wlp0s26u1u2 down
iwconfig wlp0s26u1u2 mode monitor
ifconfig wlp0s26u1u2 up

That particular interface will turn to monitor mode, but when i issue airodump-ng it returns:

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 mon0

Can someone please guide me to something that I read about or suggest something that I can do?
Thank you so much!! smile

Re: Siocsifflags error : Name not unique on network problem

Hey, same issue here. I wish that I could get this working as I was looking forward to using my archlinux box for wireless security audits. Unfortunately I have had to switch to a Kali live boot for this. sad

Any work on this would be greatly appreciated!
Thanks!

Re: Siocsifflags error : Name not unique on network problem

I can get monitor mode to work using iwconfig:

First, take the wireless interface down:

sudo ifconfig wlan0 down

Then, change your wireless card to monitor mode:

sudo iwconfig wlan0 mode monitor

Next, bring your wireless interface up:

sudo ifconfig wlan0 up

Then, you can run airodump-ng:

sudo airodump-ng wlan0

But using airmon-ng is much faster and easier to use, and I would love a fix for this.

Thanks.

Re: Siocsifflags error : Name not unique on network problem

I'm having the exact same issue as OP.  If anybody found a solution let me know.

I am running airodump-ng on the mon0 device with this error:

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 mon0

Does airmon/aircrack work with the intel card? (I am confused about the unknown chipset)

Hm, have you tried killing NM and the rest, and running airmon-ng against an unassociated interface?

but still it doesn't work.

You should alias "localhost" to 127.0.0.1, like for example

127.0.0.1 localhost.localdomain localhost divingpigeon
::1 localhost.localdomain localhost
192.168.0.20 host1
...

lo        no wireless extensions.

So, mon0 isn't created... why do you want to run anything else?
