I've not said anything earlier, but I guess I probably should. If you want to pull things at a fairly fast rate (probably more than once a minute), it may be better to use a solution that says connected to the BMC continuously instead of doing a connection each time. That way, there's no setup overhead and the performance will be better. The downside of this is that you can't make very many connections to most BMCs, so if you have more than, say, 2 or 3 machines that need to connect to the BMC, it probably won't work. However, you will run into problems polling, too. In that case, it may be best to have a single server that connects to the BMC and provides services to the clients. OpenIPMI (the software that I mostly wrote) will stay connected continuously, and you can use perl and python as well as C. But it will be more work to program it. -corey > Andy > > -----Original Message----- > From: Detweiler, Dick [mailto:dick.detwei...@avocent.com] > Sent: Tuesday, December 15, 2009 1:19 PM > To: Detweiler, Dick; ipmitool-devel@lists.sourceforge.net > Subject: Re: [Ipmitool-devel] RAKP Insufficient Resources response > fromaniDRACm610 blade... > > Having dug a little deeper into the IPMI spec, I note that the resource > problem is generated at the very beginning of ipmitool establishing a > session as the managed system sends the error in its RAKP message 2 > response.
