BuildStatus PyPiVersion Documentation Status Python versions Coveralls CodeClimate Codacy Badge


  • native RMCP interface

  • legacy RMCP interface (using ipmitool as backend)

  • RMCP+ interface (using ipmitool as backend)

  • system (KCS) interface (using ipmitool as backend)

  • IPMB interface using the Total Phase Aardvark

  • IPMB interface using ipmb-dev driver on Linux

Tested Devices

  • Kontron mTCA Carrier Manager

  • Kontron CompactPCI boards

  • Pigeon Point Shelf Manager

  • HPE iLO3/iLO4

  • N.A.T. NAT-MCH



For IPMB interface a Total Phase Aardvark is needed. Another option is to use ipmb-dev driver on Linux with an I2C bus, driver of which supports slave mode:

For legacy RMCP, RMCP+ and system interface (KCS) the installtion of ipmitool is required.


Using pip

The recommended installation method is using pip:

pip install python-ipmi

Manual installation

Download the source distribution package for the library. Extract the the package to a temporary location and install:

python install

Below is an example that shows how to setup the interface and the connection using the ipmitool as backend with both network and serial interfaces.

Example with lan interface:

import pyipmi
import pyipmi.interfaces

# Supported interface_types for ipmitool are: 'lan' , 'lanplus', and 'serial-terminal'
interface = pyipmi.interfaces.create_interface('ipmitool', interface_type='lan')

connection = pyipmi.create_connection(interface) = pyipmi.Target(0x82)[(0x81,0x20,0),(0x20,0x82,7)])

connection.session.set_session_type_rmcp('', port=623)
connection.session.set_auth_type_user('admin', 'admin')


ipmitool command:

ipmitool -I lan -H -p 623 -U "admin" -P "admin" -t 0x82 -b 0 -l 0 raw 0x06 0x01

Example with serial interface:

import pyipmi
import pyipmi.interfaces

interface = pyipmi.interfaces.create_interface('ipmitool', interface_type='serial-terminal')

connection = pyipmi.create_connection(interface) = pyipmi.Target(0xb2)

# set_session_type_serial(port, baudrate)
connection.session.set_session_type_serial('/dev/tty2', 115200)


ipmitool command:

ipmitool -I serial-terminal -D /dev/tty2:115200 -t 0xb2 -l 0 raw 0x06 0x01


Python > 3.6 is currently supported. Python 2.x is deprecated.
