# Boot email notification by Charlton Trezevant 
# Version 3.0

###SETUP:
# Just paste it right in to /etc/rc.local
# Note that this depends on having mailx and postfix installed.
# See below for more info.

###DEPENDENCIES
# This script requires mailx and postfix to be installed. 
# Install mailx like so: sudo apt-get install bsd-mailx 
# You can then create an email address for your pi and send outgoing mail through that 
# (see https://www.linode.com/docs/email/postfix/postfix-smtp-debian7), Or, if you prefer, 
# you could also use your own mailserver at your domain.

###CONFIGURATION
# At the top of the script are 3 different variables. 
# --
# The first is EMAIL. This should contain the email address to which messages should be sent. If you like, you can add multiple
#  addresses, separated by commas. This can either be your email, or your phone's SMS email (http://goo.gl/hhAABm for SMS-to-email info)
# --
# The second is HOST. This automatically gets the machines hostname and requires no configuration on the part of the user.
# --
# The third is the LAN interface that the LAN IP should be pulled from. Usually, this is eth0, but it could also be em0. 
#  run ifconfig to see the list of available interfaces. Change this if you want to get the IP of a different network interface than
#  the default.

# Also, on some systems, /sbin/ifconfig is not installed. This command is usually replaced with /sbin/ip, with addresses shown using
# The command "ip addr". 
# Should this be the case, try using the following command:
# /bin/ip addr | /bin/grep inet | /usr/bin/tail -n 2 | /usr/bin/head -n 1
# Which should produce somethinf along the lines of:
# inet 192.168.0.12/24 brd 10.0.1.255 scope global eth0

EMAIL='<your_email>@example.com'
HOST="$(cat /etc/hostname)"
LANIFACE='eth0'
