1. im a great newbie on linux, i use the backtrack 2 livecd with a netgear 511T cardbus, it works very well, i catched IVs with airodump but i don't know where is the saved file for use with aircrack?

2. I'd like save the captured file.ivs on a external hard drive while airodump is running but i don't know which linux commands i have to do?

thanks for your help
