# description: ipmi_port reserves the IPMI RMCP port 623 from portmap
#		which prevents portmap from trying to use port 623.
# 		This script also applies any saved IPMI thresholds, and
#		copies the bmclanpet.mib to where SNMP can find it.
#		It is recommended that this service be started for
#		all systems with ipmiutil that also have portmap.
