ipmiyuck-pullinfo.yaml

# 
# quick hack
# 
# this playbook will check ipmitool for the ipmi mac address
# and create a line formatted for dnsmasq's /etc/ethers file
# ipmi address will be in the ipmi subnet, but last octet
# will mirror the primary network interface on the host
#
# see DNSMASQ(8) for additional information on dnsmasq
# 
# example :
# host A's primary IP is 10.10.10.99 on eth0
# the ipmi mac address is 34:17:eb:e5:00:1B
# the ipmi subnet is 10.11.12.0/24
# 
# ipmimac-etc-ethers is populated with :
# 34:17:eb:e5:00:1B 10.11.12.99
# 
# This script gathers additional info for CMDB cross referencing as well
