My curiosity on cracking WEP lead me to this handy tutorial on Tom's Networking: Part 1:http://www.tomsnetworking.com/Sections-article118.php

However, when I get to the step of using Void11 Part 2: Step 4 http://www.tomsnetworking.com/Sections-article120-page4.php, I receive some errors that didn't allow me to create the deauth attack. I was wondering if the Tom's faithful encountered any of these, and if so, what were the remedies?

Commands for setting up a void11 deauth attack
#####
switch-to-hostap
cardctl eject
cardctl insert
iwconfig [interface] channel [thechannelnumber]
iwpriv [interface] hostapd 1
** I receive error that HOSTAPD is not a known command
iwconfig [interface] mode master
void11_penetration -D -s [macOfStation] -B [macOfAp] [interface]
** I receive the following errors:
ioctl(SIOCGIFINDEX): No Such Device
ioctl[PRISM2_IOCTL_HOSTAPD]: Operation Not Supported
ioctl[SIOCGIFFLAGS]: No Such Device
Bye!
ioctl[PRISM2_IOCTL_HOSTAPD]: Bad file description
ioctl[SIOCGIFFLAGS]: Bad file description
#####
I would say I'm relatively new to linux, and definately unfamiliar with KNOPPIX. Searches on these errors didn't produce much.

Any help is greatly appreciated. Thanks

What Wireless card / chipset are you using?

I ran into this same issue a while ago using Auditor, turned out that the card I was using didn't have a chipset supported by void11

A line of the error code you posted:

* ioctl[PRISM2_IOCTL_HOSTAPD]: Operation Not Supported *

From my understanding, that means that your wireless NIC is receiving a command that it doesn't understand / support. Its basically saying "You want me to do WHAT? Sorry, dunno how to do it. Piss off."

Problem may be solved by installing a card with a prism2 chipset.

Or, you could hang tight and wait it out. I understand that an updated distro of Auditor is being released soon, and its supposed to incorporate several features from Whax as well.

Good Luck.

Thanks for the quick reply.

I am using a Intel PRO/Wireless 2100 3B Mini PCI Adapter that comes OEM in a IBM Thinkpad R40.

I found some documentation on this wireless adapter with respect to Linux.
http://www.thinkwiki.org/wiki/Ipw2100

Unfortunately, I see no mention of prism2 on there. However, I cannot find a definitive list of cards using this chipset so I cannot confirm whther this card is or isn't Prism2. Any suggestions, or ideas on finding a definitive list.

Thanks again

Yup, I figured as much.

Your chipset, for the record, IS IntelPro Wireless 2100 (also known as ipw2100) and you pretty much can't do crap with it. It, and the ipw2200 chipet that I was originally using, are designed as part of Intel Centrino **insert copyrighted Intel noise** technology.

Over all, its a pretty good card in my opinion, aside from its blatant "anti-hacker" mindset with deproves us of the ability to do a lot of things with it. Hell, until recently there werent even any Linuxdrivers for the damned thing, unless you could manage to get NDISwrapper functioning.

Head out to BestBuy and get yourself a Cisco or prism2 based wifi card and you'll have better luck.

Thanks for the reply again.

When purchasing a card, do you see any mention of prism2 on the box? I've purchased a fair share of cards for corporate clients and never noticed anything about Prism until I stumbled onto this gem of a project.

I tried a DLink PCMCIA card and that didn't even load into Knoppix.

When you say Cisco, are you including their Linksys brand?

Do you have any resources on Prism2 that you could send my way? I feel very unknowledgable on this topic...

Thanks again.

Here is alink to a web site that tells you what chip sets are used with which cards.

Hope this will help you.
