AttributeError: 'NoneType' object has no attribute 'routing'

Hello Guys, anyone would know what am I doing wrong?

Here's one of my servers:

$ ipmitool -H 10.8.1.18 -U root -P pass -I lanplus fru print 0
     Board Mfg Date        : Wed Oct 24 05:37:00 2018
     Board Mfg             : MYMFG
     Board Product         : MYBPD
     Board Serial          : MYBSN
     Board Part Number     : MYBPN
     Product Manufacturer  : MYMFG
     Product Name          : MYPPN
     Product Version       : 01
     Product Serial        : MYSER
     Product Asset Tag     : MYAST

Trying to deal with FRU in a script:

#!/bin/env python
    import pyipmi
    import pyipmi.interfaces
    def main():
        interface = pyipmi.interfaces.create_interface('ipmitool',
                                        interface_type='lanplus')
        ipmi = pyipmi.create_connection(interface)
        ipmi.session.set_session_type_rmcp('10.8.1.18', port=623)
        ipmi.session.set_auth_type_user('root', 'pass')
        ipmi.session.establish()
        fru = ipmi.get_fru_inventory(0)
        ipmi.session.close()
    if __name__ == "__main__":
        main()

but I get this error:

    if target.routing is not None:

Ideas? Thanks!

Hi,

take a look into the example https://github.com/kontron/python-ipmi/blob/master/examples/dcmi.py.

You have to set a proper target.

Thanks, I added the target, now I'm getting something different:

#!/bin/env python
    import pyipmi
    import pyipmi.interfaces
    def main():
        interface = pyipmi.interfaces.create_interface('ipmitool',
                                        interface_type='lanplus')
        ipmi = pyipmi.create_connection(interface)
        ipmi.session.set_session_type_rmcp('10.8.1.18', port=623)
        ipmi.session.set_auth_type_user('root', 'pass')
        ipmi.session.establish()
        ipmi.target = pyipmi.Target(ipmb_address=0x20)
        fru = ipmi.get_fru_inventory(0)
        ipmi.session.close()
    if __name__ == "__main__":
        main()

Error:

I literally copy&pasted the script you referenced, and I get the same rc=127, on centos7/py2.7&py3.6 and centos8stream/py3.8, ubuntu2004/py3.8. Thanks.

What version of python-ipmi are you using?
