What is LightSquid?

LightSquid provides an easy and free method of monitoring internet usage on your network. LightSquid is a Squid log analyzer that runs on Linux. By parsing through the proxy access logs, the package is able to produce web-based reports that detail the URLs accessed by each user on the network.

This package works well for both small and large networks. The reports have some useful features that allow you to see bandwidth usage, URL access by date and time, and top site reports.

Since LightSquid runs directly on your Linux machine using the cron, it is both centralized and stealthy. Users on the network have no way of knowing their traffic is being logged and analyzed using this method.

Key features:

• fast and simple install
• fast log parser generatesmall per user data file
• perl based cgi script for dynamic generated report pages
• html template for design
• no database required
• no additional perl module
• various reports
• user groups support
• graphics report (v 1.6+)
• real name (v 1.6+)
• multilangual interface
