Cfengine is a free software package for automating the configuration and maintenance of networked computers. Its purpose is to implement policy-based configuration management. A System Engineer's Guide to Host Configuration and Maintenance Using Cfengine describes all aspects of using Cfengine 2. Beginning with the fundamentals of Cfengine itself, the booklet takes you though the policies, shows you how to build an infrastructure. It then covers host monitoring and anomaly detection, as well as the management process. Finally, the booklet provides case studies and sample policies and a section on extending Cfengine through additional modules and methods.
