Using nmap should work to see if the port is open (or more notably, if
you can nmap the IP you configure for IPMI.

It should simply be enabling IPMI (via Lan_Channel), configuring a
proper IP, MAC, subnet, gateway, etc.  If you're configuring an
identical IP address as the host machine, it may be worth configuring a
different one just to try.

I've witnessed some motherboards not "take" a configuration until you
hard-reset the node.  Hard-reset meaning hitting the power button
physically.  Or you can cold-reset the BMC by running

bmc-device --cold-reset

to get the same affect. (I believe this is the equivalent of mc reset
cold below)

It's also possible there could be something in your BIOS affecting
things.  I've seen some motherboards have BIOS options for putting the
ethernet card into certain modes which allow/not-allow IPMI.

Some motherboards have factory reset capabilities, but they are
manufacturer/OEM specific.  I haven't come across one for Intel
motherboards yet, so there aren't any in ipmi-oem yet.

FreeIPMI doesn't have something that high level/specific at the moment
(I've been thinking of writing one, but haven't had the time to).
FreeIPMI currently has libraries/tools that are more for others to build
upon for that feature.
