Thanks for the reply and sorry I was so late. I just checked it.
Everything sounds right, I have the latest version of kismac installed but can't run in active/passive mode because I am running Leopard. And yes, you do need to reinject packets to create more traffic in order to crack the WEP faster. Otherwise, as you said, it would take a very long time.
I found a program that is completely CD bootable and Linux based that I have been messing with for a while. It has all the tools included in it for WPA/WEP cracking. Also all kinds of other stuff for network administration and monitoring. it is really an awesome program and can be booted from your Mac, at least I could from my MBP just by holding option at startup it gave me the option.
It is called BackTrack 2. You can click
here to download it. You have to burn it to CD and boot from it.
You will need to read instruction on how to use it and all the functions of it. Click
here to view how to boot from the CD and an over view of all the tools.
Here is a walkthrough to crack WEP using backtrack.
It is a great piece of software for network security evaluation. Once you learn the proper way to use it, the possibilities are endless.
