Jeff Starr’s broad-spectrum, server-level weapon against malicious activity, the Perishable Press 3G Blacklist is comprised of a large block of code which ideally should be added to your site’s http.conf file, although if you don’t have that capability (I don’t), the code may be added to your site’s root .htaccess file.
First, ensure these requirements are met:
- Linux server running Apache ((I’m not sure if this will work on Mac or Windows running Apache, but you’re welcome to try it out.))
- Apache module
mod_aliasenabled - Apache module
mod_rewriteenabled - Ability to edit either your Apache server configuration file (
http.conf) or your site’s root.htaccessfile.
If either mod_alias or mod_rewrite are not available, the sections of the blacklist which require them will simply be skipped. Of course, if you want to be sure about any of the requirements, check with your host. They should be able to tell you all you need to know.
Ready for the blacklist? Paste this large chunk of code into the appropriate place. In an .htaccess, you’ll probably have the best luck by placing this code at the start of the file, prior to any other code.
