Re: [Ipmitool-devel] Accessing ipmitools over network

[Isabelle, F. <Fra...@ca...>]

The other question is : does iLO on DL180 really speaks IPMI ? I though this was proprietary.

I'm not sure how the IPMI cards are presented to the system, but can you
query them locally, i.e. ipmitool -I open sdr or ipmitool -I imb and
create nagios plugins locally, that way you don't need to fiddle around
a proxy.

However, all this takes away one major pro of a dedicated port, you will
not be able to query/power cycle the box remotely if the box is down
already.

My advise would be, buy a cheap switch and connect the dedicated ports
to it. A working 48 port switch costs less than $300 and is far less
hassle - provided the boxes are not too far away from each other.
