On SuperMicro motherboards you will sometimes get the following error when using certain functionality of the the IPMI config utility:

./IPMICFG-Linux.x86_64 -dhcp

[kcs] kcs_error:

[kcs] kcs_error_exit:

This is due to a missing kernel module that is required. On CentOS you can install the kernel module with the following (note that the package name may be different depending on the operating system):

# yum install OpenIPMI

# modprobe ipmi_devintf

./IPMICFG-Linux.x86_64 -dhcp

DHCP is currently disabled.
