A Squid proxy server traffic monitoring program created in Perl. The method of monitoring is URL filtering. There are three filters: green, yellow, and red. You simply create wildcard words for each filter. For example, under the green filter you might have generic words like "software", under yellow more specific words like "downloadz", and under the red the most specific words such as "warez". The Perl script then finds sites that have been visited with those separate filters and makes an HTML report. In addition, the script can send a winpopup message (through Samba) to either the offender warning them of their possible violation or the administrator.
