I think I've found a bug. When You use john to decrypt WPA cap (I used it with both letters and numbers, but I doesn't think it matter), then You manually close xterm window, where decryption is going, aircrack-ng is *still* running - without any window You can open/close/whatever. It's also consuming 80-90% of Your CPU time, on 900 mhz Have to kill it via xterm using PID.

It happened to me some time ago, but then. I got no clue why. Yesterday, it happened with fully charged battery (I was planning a long train trip today), and by evening, I got only 20% left of dual-scud ;p, with quite warm phone. That was the moment I decided to investigate further. No big deal, but can be quite irritating, if You do not except it and it will drain Your battery in few hours (normal batter can be drain in even 120-150 minutes, from full)

I'm not sure, if it is pure fAircrack bug, or one in maemo aircrack-ng - but seems to happen only, when I use fAircrack john decryption. So I decided to post here.
