Free ipmi software for linux

OpenIPMI project is an effort to create a full-function IPMI system to allow full access to all IPMI information on a server and to abstract it to a level that will make it easy to use.
OpenIPMI consists of two main parts: A device driver that goes into the Linux kernel, and a user-level library that provides a higher-level abstraction of IPMI and generic services that can be used on any operation system.
Main features:
- Allows multiple users.
- Allows multiple interfaces.
- Allows both kernel and userland things to use the interface.
- Fully supports the watchdog timer.
- It works like IPMI drivers are supposed to. It tracks outgoing messages and matches up their responses automatically. It automatically fetches events, received messages, etc.
- It supports interrupts (I have tested them now).
- It has backwards-compatability modules for supporting the Radisys IPMI driver and the Intel IMB driver.
- Its modular. You dont have to have the standard userland interface. You dont have to have the watchdog. Etc.
- It supports generating an event on a panic.
The OpenIPMI Library
Raw access to IPMI is rather difficult to use. Parsing SDRs, scanning for devices on the IPMB bus, scanning for events, and handling all the pieces is rather complicated. The OpenIPMI library provides a higher-level abstraction of this, the user of the OpenIPMI library deals directly with sensors and entities and does not have to worry about the lower-level details of IPMI.
Note that the OpenIPMI library is not Linux-specific. It was written with an os-layer so it could be ported to other operating systems. Of course, it works by default on Linux, but I would like to see it running on other operating systems. It includes an IPMI LAN interface, an interface for the OpenIPMI driver, but interfaces for other drivers and connections could be written.
The OpenIPMI library also includes the ipmicmd program, a small program that lets you inject and receive messages. You can register for incoming commands, set your source IPMB address, and other nifty things, too.
Enhancements:
- SDR writing now works.
- Assorted build fixes were made.

OpenHPI is an open source project created with the intent of providing an implementation of the SA Forums Hardware Platform Interface (HPI). HPI provides an abstracted interface to managing computer hardware, typically for chassis and rack based servers.
OpenHPI project includes resource modeling; access to and control over sensor, control, watchdog, and inventory data associated with resources; abstracted System Event Log interfaces; hardware events and alerts; and a managed hotswap interface.
OpenHPI provides a modular mechanism for adding new hardware and device support easily. Many plugins exist in the OpenHPI source tree to provide access to various types of hardware. This includes, but is not limited to, IPMI based servers, Blade Center, and machines which export data via sysfs.
Enhancements:
- This release is the first to contain and use the new HPI B.02.01 header file.
- It contains the following new APIs: saHpiResourceLoadIdGet, saHpiResourceLoadIdSet, saHpiGetIdByEntityPath, saHpiGetChildEntityPath, saHpiResourceFailedRemove, saHpiEventLogCapabilitiesGet, saHpiIdrFieldAddById, and saHpiIdrAreaAddById.
- Users can now configure the default domain by using domain id 0 in the config file.
- The new APIs are still in beta and only available in non-daemon mode (--disable-daemon during configure).

ConMan is a serial console management program designed to support a large number of console devices and simultaneous users. The project supports local serial devices, remote terminal servers (via the telnet protocol), and external processes (e.g., using Expect to control connections over telnet, ssh, or IPMI Serial-Over-LAN).
Its features include logging (and optionally timestamping) console device output to file, connecting to consoles in monitor (R/O) or interactive (R/W) mode, allowing clients to share or steal console write privileges, and broadcasting client output to multiple consoles.
Main features:
- logging (and optionally timestamping) console device output to file
- connecting to consoles in monitor (R/O) or interactive (R/W) mode
- allowing clients to share or steal console write privileges
- broadcasting client output to multiple consoles
Enhancements:
- A console script was added for Sun ILOM.
- Minor fixes were made to the existing console scripts.
