Aircrack - Fast Wep Cracking Tool, got it built, need to start testing Options

[speculatrix]

wep as everyone knows should only be used where either you're just stopping casual drive-by intrusion, or where you don't care TOO much about someone breaking in.

aircrack is a latest generation tool set for capturing, analysing and breaking wep keys.

I've made it build on zaurus, am going to be trying to test it, and I was wondering if anyone else would be interested in giving it a go; I am wondering if my Zonet/Mercury card will be 100% suitable.

I am getting an error "malloc 60MB" when trying to run the aircrack from ELSI. It's on a C860 with Sharp ROM and the file (.dump) was generated by Kismet. Is it just a matter of adding swap space (how much) or something else?

Thanks,

Felipe

Did you get this figured? I am also getting this error using a Wellenreiter packet dump file with the following message:

malloc(80 MB) failed

The packet dump file is pretty small - the test one I am using is only 200k.

This is on an C860 with Cacko 1.22a and a DLink660. Aircrack is from ELSI v 2.1.1. Interested to know how to get this working! Have any of you guys had success?

Same here. I'm getting the 80MB version of the error running the Sharp ROM on my 6000.

I have a sharp rom C3000 with same aircrack error.

To solve the issue I have created a swap file (128 MB) as following on my hardisk ( for c6000 or other, I think same can be done one a CF memory card) :

open a terminal as supervisor and then type following commands :

dd if=/dev/zero of=/hdd3/swapfile bs=1048576 count=128
mkswap /hdd3/swapfile
swapon /hdd3/swapfile

to check swap is activated type : cat /proc/swaps

error on aircrack should have now disappeared.

Ummmm.

You could just use the Zaurus to create the capture files, then use aircrack on a normal desktop machine/laptop to actually break the wep key.

You'll need a fairly large chunk of data to get the WEP key broken, for a 128bit key then something like a gig of data may need to have passed over the WLAN in order for enough IV's to be captured to break the WEP key.

Also, using airodump and setting it to just store IV's will greatly reduce the data stored, you can then easily transfer this back to a desktop machine to run aircrack on it, etc

HTH.
