Squid-Based Traffic Control and Management System

When Web traffic became a major use of the organization's network, this university put in a control system to track and limit access, using the open-source Squid caching system.
Conclusion

In this article, we considered the state of the art in the Internet access control problem. We proposed several methods for its solution and considered the variant based on the Squid proxy server, which has been implemented in the LAN of BSPU. Our solution is not the panacea and possibly has several drawbacks, but it is rather simple, flexible and absolutely free.

We also should say that our Web-programmer, Elmir Mirdiev, is now finishing the implementation of a small PHP-based Web site designed for system management and user statistics reporting. The user-detailed statistics are generated from the Squid logs using the Sarg system.

Other information can be obtained from the source code of the system. You can get the whole modified source code of Squid version 2.5STABLE7 tarball on our site or only the patch file. We will be glad to answer your questions by e-mail.
