pattern_offset

[ricardo.teixas at gmail.com (Ricardo F. Teixeira)]

Hi list,
I'm trying to port an exploit, I'm  sucede to crash the aplication
with rand_text_alpha_upper(220) of garbage and after of segmentation fault,
eip register is filled with 0x6f344400.

When I try to find the exact offset needed to overflow the process, with
pattern_offset.rb, it tells me nil (null), why?

$ ruby /opt/local/msf/tools/pattern_offset.rb 6F344400 72 nil

Can someone point me what I'm actually doing wrong?

Thanks,

Ricardo F. Teixeira
