Regulus is a real-time monitoring / accounting / billing software package. It allows you to track your user acceses, maintain logs and can restrict user acceses according to any policy you have defined. User acceses are constantly monitored by the second (frame level), by the daemon (rulers) component in the software that operates on your central system 24 hours a day. Regulus is composed of two (2) programs: the rulers component and one or more regent components. Combined in one easy to use software package. The two (2) components work together to control and keep track of user  accesses on your systems. Regulus is intended to be as portable as possible in the UNIX world by complying with the POSIX-1003.1 standard. Please contact us if you need to have Regulus ported to another UNIX flavor.Regulus can work side by side, RADIUS is a very good standard to do user authentication, egulus' purpose is to make sure the  customer is entitled to be on your network. If RADIUS lets a user enter the system and Regulus does not have the necessary information to bill the user, Regulus will leave the user online but will send a "squatter alarm" to the operator.
