3x WLAN in 1 laptop?

[wehugheog]

Hi everyone

Ok, I am, for the first time, experimenting with LINUX.
I downloaded: KNOPPIX STD, AUDITOR and Back|Track 2.0 for, I guess, the obvious reasons...

After testing a little bit I did notice that Auditor does recognize my internal Atheros a/b/g card and does recognize my 2 PCMCIA Netgear WG511t's. That looks promising.

Now for the question:

Can I use i.e.:
internal card -> internet connection (regular)
1 PCMCIA card -> monitor mode
1 PCMCIA card -> injection mode

at the same time?

The LINUX versions I use are all running from CD.

I am new to the forum so please bear with me

[censored], you're really climbing a steep hill.

If you are really serious about _using_ Linux, I would recomend you trying ubuntu or something, first.

So you can practise commandline usage and just general tinkering.

But to _start_ with backtrack and packet injection, now that's a challenge.

Well, back to the subject. To answer your question, yes, you can use all of the NIC's at the same time.

The Atheros chipsets even supports packet-injection while in monitor mode. So you can use only one NIC for both monitor and injection if you like.

The WG511t's are also atheros based I think.

anyways, to use the internal nic for connectivity do this:


become root. (I'm assuming ath0 is your primary, internal nic)

#iwconfig ath0 essid "your-accesspoint" key "yourwepkey-ifyouhaveone"

#dhclient ath0

or

#ifconfig ath0 up 192.168.0.33 (or whatever you wish)
#route add default gw 192.168.0.1 (or whatever your routers ip is)

#nano /etc/resolv.conf

add:

nameserver <dns-server-ip>

close and save.

try to ping.

#ping ftp.sunet.se

wash.rinse.repeat.

and about aireplay, I don't really remember the syntax, but it's well documented on their site.

But be careful, wardriving/sniffing/using unprotected APs is one thing (and is legal/semi-legal), actively braking into and cracking a wepkey or WPA key is however a serious crime

seneca:

Thanks for the help.

I got the internal Atheros working. sniffing AND injecting (of course on my own wifi router).

The netgears are indeed Atheros (that is why I bought them)

Also, I already hacked my own wep-key. very very easy, I have to work on that to make it more secure (hence the testing).

As for the steep climb: I guess so, but since I am (even pre-) DOS-generation (started with a Acorn Electron, remember that?) I am still kind of used to command lines and figuring out the options etc. etc. Not easy though beginning to part-time learn a new OS.

Next projects:
-learning more LINUX
-cracking my wifi without a client attached
-securing my wifi router much much better

As for you final comment: Yes, I do sometimes use unprotected wifi, since I am travelling so very much (sometimes no other option).
As for cracking someone else's wifi, not really my game, there usually is some paid-as-you-go network in the air BUT it is good to know all this to secure my own wifi gear.

Well... I sort of guessed you would be quite experienced to try something like that

Never used an Acorn before, it was release a few years before I was born

Good work on getting the setup to work as you wanted.

I guess you will be trying to de-auth/brute-force wpa now huh?

And btw, you have to try running kismet with your 3 nics, it's excellent. And probably a prequisite if you're gonna look for 11a APs since there's so many channels.

Good luck with your tinkering

[seneca]

And another thing... About you cracking wep on an AP with no wireless client....

Some cheap APs "leak" arp--requests from lan to wlan, so if you discover a wired client on that ap, you can use that to generate arp-requests and wep-encrypted traffic.

Seneca,

I have been travelling a LOT the last weeks, so....

Thanks for the input, I will take a few days trying some stuff out!!

I will let you know the results.

Seneca,

Can't seem to inject with Auditor nor Backtrack 2.0

Or should we take this pm?
