This script allows to process racadm command on a set of remote dell server idracs without
have shared the public key of the server (i.e.: ssh login by password).

Use of --email-alert[1-3] enable all email alerts.

Idrac version 7 and later

usage: ./remote_racadm.sh -b | --base-plage-ip XXX.XXX.XXX. -i | --interval XX[-XX]
		# Setters configuration
		[ -a | --alert-enable ]
		[ -c | --dns-address2 ] address			 
		[ -d | --dns-address1 ] address
		[ -e | --test-alert-email ]

		[ -h | --help ]
		[ -j | --disable-email-alert1 ]

		[ -l | --disable-email-alert3 ]
		[ -m | --gw-address ] address
		[ -n | --ntp-server-address ] address
		[ -o | --web-server-time-out ] min
		[ -p | --idrac-password ]              # Deprecated, the password is requested to the prompt
		[ -q | --set-prefix-racname ]
		[ -r | --set-racname ]
		[ -s | --smtp-address ] address
		[ -t | --timezone ] Country/City
		[ -u | --idrac-user ]                  # Asked at the prompt if not informed

		# Server action
		[ --graceshutdown | --hardreset | --powercycle | --powerdown | --powerup | --powerstatus ] # Hardreset means reboot

Examples: 
	On a single server:

		# Set some parameters
		./remote_racadm.sh -u root -b 192.168.255. -i 254 --set-racname NAME_SERVER --webserver-title-bar
		
		# Set some parameters without any interaction
		./remote_racadm.sh -u root -p calvin -b 192.168.255. -i 254 --set-racname NAME_SERVER --webserver-title-bar

		# Get some information
		./remote_racadm.sh -u root -b 192.168.255. -i 254 --get-alert-enable --get-dns-address1 --getractime --get-gw-address --get-ntp-server-address --get-web-server-time-out --get-racname --get-smtp-address  --get-timezone  --get-dns-domain-name --get-email-alert1

	On a set of server:

		# Configuration
		./remote_racadm.sh -u root -b 192.168.255. -i 10-100 --gw-address 192.168.255.254 -a -d 8.8.8.8 --smtp-address smtp.example.com --set-prefix-racname NODE_ --LCD-display-racname -x bob@example.com --ntp-server-address 192.168.255.254 --timezone Europe/Paris
		# Idrac name will be NODE_10,NODE_11,...,NODE_100
		
		# Test email alert
		./remote_racadm.sh -u root -b 192.168.255. -i 10-100 --gw-address 192.168.255.254 --test-alert-email

		# Server action
		./remote_racadm.sh -u root -b 192.168.255. -i 10-100 --hardreset

Bugs known:
	The sending of a test email sometimes requires a latency between the time when we configure the idrac and the time when we do the test of sending mail.
	It's sometimes necessary to go through the web interface of the idrac to make the first test of sending email by hand ...
