Hey, by 'off the server' I assume you mean you want a script you can install and track yourself ?
I'm looking for the same thing, I found a few nice looking ones, but there's too many to choose from.
Do a search on hotscripts.com, or even google for "free php traffic analisys" or something similar, there are hundreds.
Please, if you find a good one, tell me so I can use it :classic2:
