Two airdrop-ng problems.

[ringer]

Hello,

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 16evice 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?

Many thanks!

Answer I:
To set the channel in airodump-ng you have to add -c. For example: "airdrop-ng -c 11 wlan0"

Answer II:
To run airodunp-ng you have to:
airmon-ng stop wlan0
airmon-ng start wlan0
airodump-ng mon0

To fix the resource busy problem you have to run "airmon-ng stop mon0", then "airmon-ng stop wlan0"
(stopping mon0 is necessary, but I do anyway.)


I hope this fixes it. If not, just let me know.
