Ok, I guess I'll just disable the timeout and not reassociate every 30s.

This is a n-ary tree search, so fast bruteforcing can only be done efficiently on the last 1 or 2 keybytes (note that the votes depend on the last chosen keybytes, so you can't just bruteforce, for example, keybyte 0 -- thus the whole fudge factor thingy). You can disable bruteforcing with -x, but in my experience bruteforcing the last keybytes leads to higher success rates.

This is probably not a major problem, attacks 0 and 1 don't require rtc anyway.

Some people reported it, but I couldn't reproduce :/. Could you start:

gdb --args ./aircrack [options] my_dump.cap

Then type run, and when it segfaults type "where". Also have a look at variables and such.

Thanks!
