Abstract
Abstract A system for the management of computer programs in a computer network environment is presented. A network license server comprises a license server daemon which provides access to a computer program based on information stored in user and license databases. To track software usage, the daemon also maintains a log file which can be accessed by and interfaced with a network administration station. The network license server protects software vendors from unauthorized use of their software while permitting software programs and users to reside anywhere on the network.
