Package: hyve-pyipmi
Hyve PyIPMIPure Python-based IPMI client developed by Hyve Design Solutions.The original purpose of this package is to provide a pure python-based IPMI client library for developing Python test scripts for the IPMI service.  It provides two categories: one is for IPMI raw commands and the other is for PyIPMI commands, which are similar to the famous ipmitool commands like "ipmitool mc info" or "ipmitool sdr list".By this pure Python library, several console programs are provided for BMC developers' convenience.Samples are included in the package to show how to write test scripts.  The performance of using this pure Python library is significantly faster than using a hybrid method of shell scripts + system calls to ipmitool to develop your test scripts.FeaturesSupported IPMI channelsRMCPRMCP+KCSMessage bridging from LAN/KCS to IPMBConsole programspyipmi - a Python program similar to ipmitoolpyipmr - a Python program supports "ipmitool raw" and has message bridging capabilitypyping - an RMCP clientpysh - an interactive shell for the PyIPMI commands, with auto completion and up/down keys to show previous commandsAuto test interfaceIPMI raw command support (see samples 1-3 below)PyIPMI command support (see samples 4-6 below)InstallationThe following steps were tested on Ubuntu desktop 16.04 LTS, 18.04 LTS, and 20.04 LTS.1) Prerequisite$ sudo apt -y install git python3-pip2) Download the source$ git clone https://github.com/hyvedesignsolutions/hyve-pyipmi
$ cd hyve-pyipmi3) Install the Hyve PyIPMI package and the console programs$ pip3 install .Test Hyve PyIPMIBy default, pip3 will install the Hyve PyIPMI package in $HOME/.local/lib/python3.x/site-packages and its console programs in $HOME/.local/bin.  Generally speaking, the site-packages directory has been included in sys.path and you need to add the bin directory in PATH by yourself.  For example, execute$ export PATH=~/.local/bin:$PATHThen, you are able to execute your first PyIPMI command.  For example, we execute something very similar to ipmitool as follows:$ pyipmi -H 192.168.0.169 -I lanplus -U root -P root123 raw 6 1Note that by default, if you choose to use "-I kcs" that goes through the Linux OpenIPMI driver, you will need root privilege to execute the program.During the first time when the package is used, it automatically generates a user config file in $HOME/.config/pyipmi/pyipmi.conf with default settings.  Then, the options supported will overwrite some of the settings.  In the above example, it specifies four options and issues a raw IPMI command.After the config file is created, you can choose to either use all the settings in the config file or continue to overwrite some of the options as the previous example.  The program will automatically record the latest overwritten values in the config file.$ pyipmi sdr list   # Just use the settings in the config file
$ pyipmi -C 2 user list  # Use RMCP+ Cipher Suite 2
$ pyipmi -U hyve -P hyve456 lan print 1  # User credential hyve/hyve456Type -h to show all the command options and use "help" command to list the available commands.$ pyipmi -h
$ pyipmi helpAdvanced UsageThe program pyipmr is equal to "pyipmi raw" + additional features.  It supportsIPMI response LUN other than 0IPMI message bridging from LAN to IPMB$ pyipmr 6 1   # Get Device ID (NetFn=App, CMD=01h)
$ pyipmr -L 1 6 1  # LUN = 1
$ pyipmr -b 6 -t 0x2c raw 6 1  # Bridge Get Device ID to destination 0x2c via channel 6Test scripts examplesSample 1#!/usr/bin/env python3
