The command $> wepattack -? shows help message with the typo in line: ... -m mode run wepattack in diffente (<-- typo I think) .. Reproducible: Always Steps to Reproduce: 1. 2. 3.
Thanks for your report. I've confirmed that the typo still exists in the current CVS sources (http://cvs.sourceforge.net/viewcvs.py/wepattack/src/misc.c?rev=1.2&view=markup), but I don't think it's worth patching at the distribution level. The upstream developers (Dominik Blunk and Alain Girardet) have been notified by email (since they don't seem to use the sourceforge bugtracker), so the typo should be corrected in a future version of the program.
