I've found it's not just the words in the dictionary.  Given a fixed
length of time, anyone can make a list with more words than they could
check.  It's the order of the words in the dictionary - getting the most
likely ones in there first.  This is especially true when you're doing
authentication attacks such as privilege escalation or openrowset in SQL
injection, and you're only going to get to try 1-5 passwords per second.
Comprehensive is great, well-ordered is critical.

The real key to passwd crackers is the dictionaries they use 
for the bruting. then better, bigger, more inclusive the 
dict, the more likely you are to get results.

Hi all

I am tryning to crack cisco md5 password.
Currently I am using a Athlon XP2500barton at 2300mhz, after 17days 
john
continue to crack at 3800c/s (it started at 4500c/s).
I am asking myself and all of you what is the best system 
(hardware) to 
crack md5 password.
I am thinking that the best way Is the powerfull (mhz) i386 
in commerce.
I've tried OpenMosix with 4 p500 nodes with john and cisilia, but 
without lucky results.
The sun 280 (dual 64bits cpu at 900mhz) go to a poor 900c/s

which is you reference system to use john on md5 password ?
