The sample2.py code I sent in the previous email should show how to do this.

Hence my original question > to this list if OpenIPMI is too powerful a tool for my simple needs :) There is no GUI code entangled in the OpenIPMI python interface, nor in the sample.py script. It is fairly entangled with the openipmi GUI, obviously, perhaps you were looking there. OpenIPMI was intended to be able to do simple things, too, but it's a huge interface and there's not much documentation help for writing simple things. > > I was hoping someone had some simple sample code that took a > username/password/ip for the bmc, and i could hard-code the hex > queries into the code and adapt it to the rest of my needs. The "sample2.py" program I sent you will work for lan interfaces, too. Run it as: sample2.py lan -U <userid> -P <password> <ipaddress> You can obviously hard-code those values in the program, if you like. -corey > > On Wed, 12 Oct 2011 10:02:16 -0500, Corey Minyard wrote: >> On 10/11/2011 04:02 PM, [email protected] wrote: >>> So I have some ipmitool raw commands i run remotely against a host's >>> bmc, and wanted to code them via the python bindings (so i can more >>> frequent polling and then do further processing w/o forking ipmitool >>> over and over). >>> >>> However the documentation is a bit sparse and i can't honestly see >>> how >>> do i construct some code to do this? >>> >>> So i have to ask, is emulating raw requests something viable via >>> OpenIPMI?
