Dudes, resizing your /tmp is only until you reboot, so /opt problem solved. Wanna hack, get 31MB free, you still would have to. vi_, '%TMPDIR' is believe what is in wifite.py, so your command might not work, no idea. You seem to be mighty linux guy, can/could you pinpoint the part in wifitie.py that dumps ivs there and deletes on exit? It always uses wep01.ivs filename, and with -p0841 attack it would be really great if it dumped it and not delete after unsuccessful crack. Sometimes running twice/thrice is required.
