Recently I purchased this book (Metasploit - the penetration tester's guide) and i am only on chapter 3. I am using Backtrack 5r2 64bit and i tried to run the command:

# /etc/init.d/postgresql-8.3 start

and the command was not found, so i looked in the init.d directory in case the version number was different and there is no sign of postgresql at all.

this part seems fundamental for the success of the book because it opens the "msf>".

Can i have some of your input please of a reference for a place to learn with up to date material?
