Title: aireplay invalid destination MAC address
Post by: eapolsniper on November 29, 2016, 05:16:48 pm
Howdy,

I'm trying to de-authenticate a wireless client but I'm running into an issue. Every time I try, I receive the message "Invalid destination MAC address". I've verified that the MAC is correct from inside the Access Point and through beacon requests from the device itself.

Syntax used:

aireplay-ng --deauth 10 -c 2 -a 34:97:F6:07:35:28 -c 18:B4:30:5A:DB:21 wlan0mon
Invalid destination MAC address.
"aireplay-ng --help" for help.

I've verified:

* Card is supported (Alfa AWUS051NH2) Also tried 2 other Alfa cards of varying models and received the same error
* -9 test works as expected
* I'm at the latest version of Aircrack (and Kali)
* I've tried both -c and -h, though I believe -c is the syntax I should be using.
* I've tried turning it off and back on again
* I ran airmon-ng check kill before setting the device into monitor mode.
* I tried -0 and --deauth
* I tried setting deauth attempts to 0, 10, 100, 1000, etc

I'm using the following syntax, anyone see my mistake or have ideas on how I can run the deauth?

The -c 2 in your command line is the issue.
Code: [Select]
-c dmac   : set Destination  MAC address i guess you want to use channel 2, aireplay-ng will be set in the channel you are sniffing with airodump-ng, you don't have to use anything for that.
