knoppix? for Dell laptop

gg-in-nj · 12-06-2004

I've got a Dell 5150 Inspiron with a Broadcom (4306KFB chip).
I tried using aeosol, but it says the card won't go into
promiscuous, so looks like windows is out (of luck that is).

Since I need to keep windows installed, and I don't have
much room on the Harddrive for a dual boot.

What is the best way to setup knoppix to using a linux
program to sniff. I'm trying to find the boundries around
my house, and just how long it will take to crack the WEP
encryption (I'm not running WPA yet, as all my PC's aren't
WPA compliant yet).

I'm look also for some file reconstruction to see how secure my
connections are as well.

What is the best live-cd / wifi sniff program combo to use for this?
and how much MB space on my windows HD should I allocate for
storage? (least amount). I have a 256mb USB drive I can clear out
and dedicate for this as well.

Thanks

A couple things come to mind here...

You do not need "promiscuous" mode to check the boundries around your house. Use NS with your current card.

As for how long it takes to break WEP, anywhere from 30 seconds to 30 days or longer (depending on luck and what kind of hardware / software you are using).

The broadcom card will not go into monitor mode no mater what you do to it.

Dutch · 12-06-2004

The broadcom card is not good under Linux, as Broadcom haven't released info or drivers for Linux. Knoppix 3.6 has the NdisWrapper driver installed, which allows you to use the Windows Ndis driver under Linux to connect to a WLAN, but that won't work for sniffing or wardriving.

Invest in a PCMCIA WLAN card based on either the Hermes chipset, if you want the best compatibility with Netstumbler, and good compatibility with almos any wireless app under Linux, or go for an Atheros based PCMCIA card, if 802.11g compatibility is necessary. Both of those cards are supported out of the box with the Knoppix Live CD, and in Netstumbler under Windows 2K/XP.

I'm currently using the miniPCI card, it was an inexpensive
ebay purchase...so it won't go to waste.

I only have a 802.11b PCMCIA card now, so I'll need to
invest in a g card. I'll have to see what's on ebay

NS will only show traffic to my machine from the router
I believe, but I wanted to see what can be picked up
from the PC's themselves outside the house. I have
the wifi AP pretty centralized in the house, with the
PC edging a circle around it.

is D-Link AirPlus G DWL-G630 802.11g 54Mbps Wireless LAN PCMCIA Card Bus Laptop Notebook Adapter an OK card.

Thanks

No, actually NS will show NO traffic on any system! NS is NOT a sniffer, it is used for AP detection. Are all your PC's wireless? You need a "G" card because your AP is "G"? A "B" card will detect "G" AP's.

What is NetStumbler?

Dutch · 12-07-2004

Further to Wrzwaldo's post.. Have you read the Readme that was included with the Netstumbler software ?

If you only see your own AP and you know for a fact there are other AP's in the vincinity that you should be able to see, my guess is you haven't read the part of the Readme file, that explains how Netstumbler should be used..

Hint (festive season mode still in effect, you lucky bastard

) : Do NOT use Netstumbler while associated to an AP.

I wanted to a G card to sniff the G traffic.

I did a search on ebay for pcmcia cards and hermes, which came up
zilch. as well as the Atheros.

Waldo, was that "No" in regards to the NS statement, or the question
regarding the usability of the cheapo PCMCIA card on Ebay I mentioned?

wrzwaldo · 12-07-2004

The NS statement... NS does not sniff traffic. It will however detect "B" and "G" AP's with just a "B" card. Of course now that I read your original post again (with my head removed from my arse) I see you are planning on using Knoppix!

Define "sniff the G traffic"...
If you are using Netstumbler, you CAN'T sniff traffic, as Netstumbler isn't a sniffer.

If you are talking about Ethereal, Kismet, etc under *nix, then get a card supported by those programs. Read the documentation for the programs, decide which card that covers the usage you are interested in, and is supported by the programs you want to use, then purchase such a card.

I.E. Define the task, then purchase the tools that best solve that task.

To cut it out in cardboard: If you have a task such as driving a nail into the wall, you won't go out and buy a screwdriver, would you ? If you had any brains, you'd purchase a hammer..

Same thing applies here.. Define the task, read the information about how to solve that task, then purchase the correct tools within your budget, to solve the task according to the information you aquired.

I googled the DWL-G630 with linux, and it wasn't promising, looked like there
aren't any drivers yet.

OK, so what is a MFG of a PCMCIA G card I can buy locally,
say at Bestbuy or CompUSA that is good for knoppix to use
on a laptop for sniffing traffic.

or a good online site that ships fairly quickly.
