After perfiorming some research, I noticed that the apache worm that is
plaguing FreeBSD machines uses the following settings (please correct me
if I'm wrong):

FreeBSD 4.5 x86 / Apache/1.3.20 (Unix):
D=-146,
B= 0xbfbfde00,
R= 6
Z= 36

FreeBSD 4.5 x86 / Apache/1.3.22-24 (Unix)
D=-134
B= 0xbfbfdb00
R= 3
Z=36
After viewing the source code for the apache worm, I did some playing around 
with the offsets, and I found that the following offsets seemed to work on 
FreeBSD 4.5 w/apache 1.3.23 quite effectively.
 -b 0xbfbfdc00
 -d -134
 -r 3 
 -z 36

Hope this helps,
