The Internet Filter

The Internet Filter If2k system for Macintosh OS X 10.4 is an easy to use and effective way to control access to web content on any web browser available for Mac OS X. 

• It can block known bad websites, websites with links to bad websites, and can block every website except those in a 'good' list if you want.
• It includes a database of 750,000 known pornography urls and sophisticated phrase filtering to block most other pornography websites.
• It can censor web page content and off-site images. 
• It allows you to customize the bad site lists, good site lists, and bad phrases list.
• It allows you to fully customize the message that appears when a website or image is blocked.
• It can read its settings and database from a remote website automatically on a timed schedule, allowing easy administration of multiple computers.

System Requirements

The filter was designed for Mac-OS X v10.4.1  Newer versions of OS X 10.4 should work fine, but OS X 10.5 will probably require a new version of the filter.

The filter, once installed, requires about 90 megabytes of hard disk space which includes the bad url databases which are expanded for very fast lookup.

The filter typically uses 20 megabytes of ram when running and very minimal cpu overhead.

The filter listens on 127.0.0.1 port 8000.  If you have any other software which uses port 8000, you will have to change the settings in that software.

The filter bypasses any HTTP proxy that is set in your computer's "System Preferences"->"Network"->"Proxies" settings.  If your network installation requires access via an external proxy, you must set the proxy and port in the "If2k Settings" application in the "Remote Settings" window.
