The default interface type (-I parameter) is lan, or in IPMI language, 
RMCP 1/1.5 connection. OpenBMC does not support this type of connection 
because it is terribly insecure. Make sure you choose RMCP+ (-I lanplus) 
as your interface type and cipher suite 17 (-C 17).

On newer versions of ipmitool, it will automatically negotiate the best 
cipher suite, but on older versions, it is best to choose 17.
