I agree Rainbow Tables can greatly speed up the process.
However, it might take you a long time to generate them. I spend 68 days
generating mine and then I found out about http://www.rainbowtables.net
These guys have the tables for sale, at the price they sell them, it was not
worth spending 68 days processing mine.
Rainbow tables are very fast, really worth a try.

An effective method to get passwords is to pass them trough specific
generated rainbow tables with a tool like CAIN.
Is this hash encrypted with md5 or another known hashing algorithm ?
Cheers

I am doing an assesment for passwords on a network, after getting the
password file I piped the output to a text file, tried to run that
against John and can't get any luck with the program. Do anyone here
uses any other password programs, and is there a better format than a
text file to store the out of the etc/shadow when trying to get the
passes.
