# findilos - Search a local network segment for iLOs
#            The iLO is the Integrated Lights-Out management processor
#            used on HP ProLiant and BladeSystem servers
#
scriptversion="1.0"
#
# Author: i...@nachotech.com
#
# Website: http://blog.nachotech.com
#
# Requires: tr sed expr curl nmap
#
# Tested with: Nmap 4.20, curl 7.17.1, RHEL4
#
# Note: Discovery of an iLO is dependent upon the Virtual Media port
#       being set to the default of 17988.  If this has been changed
#       by the iLO administrator, then this script will NOT find it.
#
#       Also, if the iLO XML Reply Data Return has been Disabled by
#       the iLO administrator, this script will not be able to
#       gather any information about the server.  It will still be
#       discovered, but all you will see is its IP address.
