Hello,
Thank you for your reply. I'm using a centos 5 will that make a
difference? Also, is there a way I can set my yum up to access your
repo from the server? I'm also interested in your php packages.
Thanks.
Dave.

Weblabyrinth is another offensive countermeasure that no one had mentioned

It basically creates a bunch of bogus pages that traps scripts that are
trying to crawl your website. It also logs anything that gets trapped so
you can tie this to
