Hi @ZombieBlue - this is just for testing purposes, it's a simulator that works with ipmitool. I'm not sure about ipmipower utility. cc @DaanHoogland

[DaanHoogland]

@ZombieBlue can you try installing and running with python3?

[ZombieBlue]

thanks @rhtyd @DaanHoogland I will try python3 first .

[ZombieBlue]

running with python36 have this issue too .

[rohityadavcloud]

@ZombieBlue can you try with ipmitool?

[ZombieBlue]

@rhtyd ipmitool can get the power status, but ipmipower can not. [root@localhost venv]# ipmitool -I lanplus -H 192.168.140.128 -U admin -P password chassis power status Chassis Power is off

[ZombieBlue]

send cmd 'ipmipower ...' and debug with pycharm

[DaanHoogland]

14 == 1110 so 14 & bin(10000000) is 0 indeed. ipmipower is sending a different format it seems. Can you give us the complete data structure? Do you know if we can recognise what tool is doing the request?

[ZombieBlue]

we can do the request by using ipmipower which can be installed with 'yum install freeipmi' and the command could be ipmipower -h 10.0.41.101 -u admin -p password --stat the data of request is b'\x06\x00\xff\x07\x00\x00\x00\x00\x00\x00\x00\x00\x00\t \x18\xc8\x818\x0e\x03\xd6'` it is a pity I don't know how to identify which tool is doing request , but I try with ipmi_sim, it can be operated by both ipmitool and ipmipower.

[rohityadavcloud]

We're historically only used ipmitool, so any PR is welcome to add support for freeipmi too.
