cowpatty4.6+patch buffer overflow

[skor78]

hi

I'm searching for hours for an answer for this problem, but had no results, i've applied the cowpatty-4.6-fixup16.patch and searched for different solutions, but i keep getting this error:

# cowpatty -r *.cap -d /wpa_psk-h1kari_renderman/wpa_tables.tar.lzma.md5sum -s ZON3OT
cowpatty 4.6 - WPA-PSK dictionary attack. <jwright@hasborg.com>

I see in other posts that they start testing passwords and the error is later on, i can't even get started.

please help.

If you patched the one in Backtrack you probably just reversed our patch since it was already working fine. That fix up patch is really old.

but i was having exactly the same error, before trying to patch. I've noticed in the system messages, saying it was already patched, but i just stating that i've searched, without results. can u please help me with this?
