ipmitool

CLI to manage IPMI systems

Quoting IPMItool homepage: "IPMItool is a utility for managing and configuring devices that support the Intelligent Platform Management Interface (IPMI) version 1.5 and version 2.0 specifications. IPMI is an open standard for monitoring, logging, recovery, inventory, and control of hardware that is implemented independent of the main CPU, BIOS, and OS." FreeBSD has OpenIPMI-compatible ipmi(4) driver for in-band IPMI operations in the base system starting from 6.2 release. On older systems sysutils/ipmi-kmod port is available.
