# IMPORTANT CONFIG BELOW
#
# if BULK_REG is 1 (set in script which includes this file, e.g. /usr/bin/connectd_control) 
# then you need to define expressions for variables hardware_id and registration_key.
# By default, this script uses the wlan0 adapter MAC address as the hardware_id 
# and the eth0 MAC address as the registration_key.
# This is likely not what you want on your system.  
# hardware_id must be unique on the remote.it system, and your device will be rejected 
# when you upload the CSV for a Bulk Registration if hardware_id is not unique.
#
# Good hardware_ids are MAC+Random, UUID, IMEI etc.  You may want to pre or postpend
# a static string onto IMEI or MAC addresses to know that you are unique on your 
# product line, as we are not sure that you can trust MAC addresses to be unique.
#
# Registration keys should be unique per Hardware ID, though it is not required. 
# Predictable registration keys are prone to cause problems if the hardware ID's
# are also predictable.  Registration keys can be a different value than the 
# hardware_id, preprogrammed random value, hash of hardware_id+secret, or any
# other value you wish to use.   remote.it does not care as long as you provide
# us the unique hardware_id and registration key in the CSV file for registration.
#
# registration key hash example:
# company secret = "xyzzy"
# registration_key=sha256(hardware_id,"xyzzy")
#
# For testing you can create a hardware_id.txt and a registration_key.txt in your
# /etc/connectd directory and this script will use these values to override
# the programmatic methods used below. Just make sure these files do not exist
# in production unless you are using them to write unique values at production
# time.
