FreeIPMI provides in-band and out-of-band IPMI software based on the IPMI v1.5/2.0 specification. The IPMI specification defines a set of interfaces for platform management and is implemented by a number vendors for system management. The features of IPMI that most users will be interested in are sensor monitoring, system event monitoring, power control, and serial-over-LAN (SOL). The FreeIPMI tools and libraries listed below should provide users with the ability to access and utilize these and many other features. A number of useful features for large HPC or cluster environments have also been implemented into FreeIPMI.
