Error connecting to BMC

[Ryan]

Thanks for the feedback! I do have amttool working, at least getting the
version string back with the 404 error. I was also able to successfully
query/change power states from the MAAS dashboard. However this didn't last
long, as I had MAAS assigning IPs on the same subnet that the AMT static
addresses were set to. It sounds like that's where I messed up.

Like J/Gary are suggesting, I will make sure I have static IPs for AMT and
then I will exclude those IPs from MAAS, ensuring that I have separate IPs
for the BMC and the node.

Thanks for the clarification!
