Hi, on server Gigabyte R163-Z30-AAB2-000 this code:

import logging
logging.basicConfig(level=logging.DEBUG)

interface = create_interface(
    'rmcp',
    keep_alive_interval=0
)
ipmi: Ipmi = create_connection(interface)
ipmi.session.set_session_type_rmcp(host=ipmi_addr, port=623)
ipmi.session.set_auth_type_user(username=ipmi_login, password=ipmi_passw)

ipmi.target = Target()
ipmi.session.establish()

print(ipmi.get_chassis_status())

throws error:

Hi,

what I see is that you try to use the native RMCP interface of this lib. But with ipmitool you are using lanplus (rmcp+). This is not compatilbe.

So the lib has the following support

• RMCP as native create_interface(interface='rmcp')
• RMCP with ipmitool as backend create_interface(interface='ipmitool', interface_type='lan')
• RMCP+ with ipmitool as backend create_interface(interface='ipmitool', interface_type='lanplus')

Hope that helps

[hthiery]

Hi, I did some work in supporting rmcp+. It is currently available for testing purposes in https://github.com/kontron/python-ipmi/tree/feature/rmcp%2B branch. You can give it a try and come with feedback.
