The freeipmi package provides command-line tools for interacting with Intelligent Platform Management Interface (IPMI) controllers.
IPMI is a standardized hardware management interface that allows system administrators to monitor and manage server hardware remotely, regardless of the operating system's state.

The freeipmi suite includes tools for tasks such as power control (powering on, off, and resetting servers), sensor monitoring (reading temperature, voltage, and fan speeds), event logging, and remote console access.
These tools enable administrators to perform essential system management functions, like diagnostics and remote troubleshooting. By leveraging the IPMI interface, administrators can manage server hardware in situations where the operating system is unresponsive or even when there is no operating system installed.
The suite supports various IPMI transport protocols, offering flexibility in how the tools communicate with the IPMI controller.
freeipmi is valuable for system administrators in data centers, server rooms, and other environments where remote hardware management is critical.

ipmi-sensors -H -U -P
This command displays sensor readings from the specified IPMI controller.

ipmi-chassis -H -U -P power status
This command checks the power state of the managed server.

freeipmi has been under active development for many years and is widely used in various Linux distributions. It provides a free and open-source alternative to proprietary IPMI management tools. The project has evolved to support newer IPMI specifications and hardware platforms.
