macchanger command question

[Nixguy]

when i change the mac for wlan 0 it works
i use the command
macchanger -r wlan0

however when i run airmon-ng start wlan0

the mon0 still has the correct mac address

iwconfig shows the fake address for wlan0, but during the injection using grimwepa i see the correct mac for mon0
if i try to change the mac by putting mon0 instead of wlan0 i get the following message
"ERROR: Can't change MAC: interface up or not permission: Device or resource busy"

and if i stop mon0 then run the command
macchanger -r mon0

i get an error "set device name: No such device"

is there a way to change the mac on wlan0 so when we start monitoring all the mon# have the fake mac address ??

Thanks

Nix

hey are you saying it changes the wlan0 but not the mon0?

are you making sure to put the mon0 down before you try to change the mac?

[WiReIs]

macchanger --mac fa:ke:ma:c1:22:33 wlan0

konsle will return with exisiting mac address & faked mac below

hope this helps

I belive your "real" interface is wlan0, and monX is virtual one. Try ifconfig wlan0 down and then change mac of wlan0. After that get it up and create monX interface with airmon-ng.

Instead of using airmon-ng to put your interface into monitor mode, try the following commands:

ifconfig wlan0 down
iwconfig wlan0 mode monitor
macchanger -r wlan0
ifconfig wlan0 up

Thanks Snayler
by doing your suggestion it worked however i created new problems

once wlan0 is on monitor i can no longer see any wireless networks on wicd network manager
so i have to change it back to managed for me to see them again

but because i changed the mac address i can no longer connect to my network, even thou i don't have mac filtering,...i'm not sure why on this one.
i logged in to my router to make sure my mac filter is off, and it was, so for it not to let me connect is a bit bizarre.

how does airmon-ng start a new vertual adapter (mon0), is it possible to do so with the fake mac?
i did a man on iwconfig and can't seem to find it, but airmon must be using

i did some search and found a thread from the old site address remote exploit where user "TheAnonymous" was having the same issue as me, however the thread was never completed

i'm assuming i can't put a link here, so the thread title was "Airmon-ng: Wlan0 Vs Mon0, Hmmm?"

my goal is to keep wlan0 as managed for my wicd network manager, and to have mon0 as my monitor adapter but with the fake mac

again thanks in advance

Never mind please ignore my second post
i figured it out

once the mon0 has been started you can stop it with ifconfig and change the mac with macchanger

so once i started the virtual adapter using airmon-ng start wlan0
i then did the following

ifconfig mon0 down
macchanger -a mon0
ifconfig mon0 up

now i have a fake mac for my wlan0 using your suggestion, and also for my virtual adapter mon0

when i was googleing this i was originaly searching on how to change mac for wlan0 and that's why i did not find it
but once i typed how to change mac for mon0 i found it in the faq for aircrack-ng

again thanks for your answer, it actually helped direct my train of thought, i never thought of using ifconfig to bring wlan0 down

Wow, i just saw everyone else’s answer

i guess it's the delay in post for the new comers, that's why i did not acknowledge your answers earlier

but thanks everyone for your feedback, much appreciated

the solution was:

ifconfig wlan0 down
macchanger -r wlan0
ifconfig wlan0 up

now that I have a fake mac for my wlan0 I started a vertual adapter in monitor mode by doing

airmon-ng start wlan0

then I put the fake mac to mon0 by doing the following

ifconfig mon0 down
macchanger –r mon0
or you can use the same fake mac on wlan0 by doing
macchanger –m <fake mac> mon0
ifconfig mon0 up


again thanks everyone for the feedback much appreciated

Cheers
