Working with intel (TM) motherboards using the Intel Gb chips,
and talking to the intel reps last year (for my previous employer) I was
led to believe that
these chips supported IPMI by giving the BMC a back door into the same
NIC that the
OS was using.
(using an I2c (SMB) interface)
On the machines I used, I am pretty sure the bios gave the same MAC
address to the BMC
side of things as the OS side of theings by default, and we had is set
up so that we used the
same IP address also.
well, i'm not positive about the MAC thing, but I am quite sure that on
IBM xSeries systems you assigned a different IP address to the BMC,
this was done in the BIOS. And, when I think about that, if it did have
a seperate IP address then it musta had a seperate MAC too...
Course, that was IBM hardware. I'll have to check up on this more
at work tomorrow.
So Julian, are you saying that you have seen this kind of functionality
work on FreeBSD??
yes, though as I said, I'd have to break intop my old emplyer's
custommer's premmisses to
absolutly confirm that they has teh same MAC address.. :-)
It's my memory though that they did.. they definitly has the same IP
address.
and yes, it did work.
the OS got a copy of incoming packets for the BMC but a firewall rule
fixed that quick enough.
Cheers,
Jack
