Descobrir o endereço do iLO para o servidor na rede

Question

Existe uma maneira de descobrir o endereço IP do iLO para um servidor na minha rede? Tenho um servidor em execução que só posso acessar via iLO (nenhum outro acesso está disponível), mas não sei o IP em que o iLO está sendo executado.

Existe uma maneira de descobrir o IP do iLO do servidor a partir da rede observando o tráfego?

O servidor é um HP proliant que executa o HP iLO

    

Answer 1

Procure portas exclusivas do ILO, como 17988: nmap -sT -p 17988 iprange ... por exemplo:

nmap -sT -p 17988 192.168.20.* | grep -A2 -B3 open

    

Answer 2

Eu usei este script em um trabalho anterior e ele funcionou muito bem, encontrando ilos que eu não sabia que existiam.

O script depende do tr expr curl e do nmap

#!/bin/bash
#
# 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: [email protected]
#
# 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.
