Crash while running brute force

I attempted to run a brute force and got the following error:

root@wopr:/opt/ikeforce# ./ikeforce.py 1.2.3.4 -b -k ******** -i DefaultRAGroup -u cisco -w 500-worst-passwords.txt '

Thanks for reporting this. I'll see if I can track it down over the weekend, is the crash reproduced every time you run it?

I tried various ways of running it and it kept crashing. Based on the debug looks like it wasn't parsing the packets right. Perhaps there is a variance in the structure.
I'll do my best to get you some pcaps but it's a client device so I'll have to sanatize a bit
