wlan0/eth0/network/dhcp Fail Fail Fail

[DavidOfLondon]

Hi guys,

I've now installed BT 4 and 3 on computers that have happily run 7 linux distros with wifi/networking access without any problems but all 3 comps refuse to allow networking to configure correctly on any of them when using BT. I've read the How To's and they don't answer my problem.

The weirdest thing is that I got my Acer AspireOne to start detecting wifi networks from my wlan0 without any problems...almost by accident. Whatever I typed was from an online tutorial somewhere and, hey presto, Wicd was detecting all the wifis around me.

Then I had to logout to check something online (no internet access by that stage) and when I logged back on to BT the settings were gone and I had absolutely no idea how to reconfigure the AP or card to start again.

Below is a ton of info for you.

I'm now on day 3 of trying to get this going again and I keep seeing people all over the internet having the exact same problem. I get messages from "no leases on persistent device" to "device not supported". Whatever I did last time enabled me to open Wicd and see dozens of networks and it was not a painful process.

It certainly wasn't just a question of using "start wicd" or anything that basic. I've downed wlan0, upped it again, set essids, set APs by chaging the key, you name it.

I eventually found, ironically, a very good Backtrack networking pdf online written by two Microsoft men but it's so out of date it didn't really help.

I would really really appreciate your help on this.

Here ya go, and feel free to ask me any questions/make suggestions:

Well out of sheer curiosity I decided to use several BT4 apps on my Ubuntu 10.04 OS and guess what? That's right, like every other person who has tried it, it worked perfectly. Same laptop, same setup, and every element of the networking was running just fine.

I STILL want to use Backtrack 4 to it's full functionality though. It's a fantastic system.

But it just won't let me access wireless networking in any way that I can fathom, and I am seeing this time and again with BT and thus I find it sad that this hasn't been fully addressed.

...and it hasn't.

Unless you pay for a course.

Ahem.

Cough.

Could you post the commands you are using from when you login? Such as the ones below...
/etc/init.d/networking start
/etc/init.d/NetworkManager start

Being in monitor mode won't help when you try to make a connection to your AP..

Again that's because you won't read and learn what you are trying to do. You just want someone to spoonfeed you everything. Well sweetheart this ain't your grand-pa's linux and we don't spoon feed the basics here. I mean really it's covered in many places. Further BT uses the Ubuntu base, that does not mean it is the same thing, or that we hold their philosophies on everything.

and I am seeing this time and again with BT and thus I find it sad that this hasn't been fully addressed.
...and it hasn't.

This has been addressed, see above, in the first quote, see the links below my signature, and the posts below as well.

Unless you pay for a course.
Ahem.
Cough.

And now your really pissing me off. See not only have you decided to run your mouth but you don't even know what you are talking about.
Ask any student of the offensive security classes or read the offensive-security faq in regards, entry number 6 clearly states: A solid understanding of TCP/IP, networking and reasonable Linux skills. My emphasis added to ensure you understand it this time.
Also in regards to your other worthless thread, see your PM box.
