Airdrop-ng Problems.

Recommended Posts


I am having two problems configuring airdrop-ng.

I am using an Atheros AR928X chipset on wlan0.

Here are the commands that I issued:

airmon-ng start wlan0

airodump-ng mon0 -w filename --output-format csv

airdrop-ng -b -l -i mon0 -t filename-01.csv -r rules.conf

Problem I:

Error Message from lorcon:

Failed to set channel 143 22:Invalid argument

Unable to set channel card does not seem to support it

Skipping packet

I checked the output from airodump-ng and sure enough there were various strange channels such as 143, 158, -1, and suchlike.

So I tried to set the channels in airodump-ng using:

airodump-ng -c 11

airodump-ng --channel 11

airodump-ng -c 1-11

airodump-ng --channel 1-11

airodump-ng --channels 1-11

Nothing worked - I still received strange channels.

So I tried:

airmon-ng start wlan0 11

airmon-ng start wlan0 1-11

Nothing worked.

And so I tried a combination of using channels with both.

Nothing worked.

Question I:

How can I set the channels in airodump-ng?

Problem II:

Another error message was:

Error Message from lorcon:

Failed to set channel 8 16:Device or resource busy

Unable to set channel card does not seem to support it

Skipping packet

Obviously channel 8 does exist.

Question II:

How can I correct this error?

Question III - not an error but curious:

The deauth requests that are sent: are they sent to the clients or to the clients and the AP? In other words: will the AP be able to log the MAC address of mon0 (to the best of my knowledge you cannot spoof the MAC for mon0 even through you can for wlan0).

Many thanks!

This isn't a jasager related question.

Channel 8 does exist; read the error it says the device is busy and can't change it.

Make sure your card supports injection. aireplay-ng -9 mon0

Read here for more information http://www.aircrack-ng.org/doku.php?id=airdrop-ng

I assumed it was the appropriate forum because of the episode when Darren combined Jasager and airdrop: http://hak5.org/episodes/episode-705

The card does support injection.

I have read that link - it tells you how to create a rules file but I was interested in understanding the errors (which the page does not mention).
