# Script for sending user defined updates using DO API
|
|
# 2015 Artem Yakimenko <code at temik dot me>
|
|
#
|
|
# activated inside /etc/config/ddns by setting
|
|
#
|
|
# option update_script '/usr/lib/ddns/update_do.sh'
|
|
#
|
|
# the script is parsed (not executed) inside send_update() function
|
|
# of /usr/lib/ddns/dynamic_dns_functions.sh
|
|
# so you can use all available functions and global variables inside this script
|
|
# already defined in dynamic_dns_updater.sh and dynamic_dns_functions.sh
|
|
#
|
|
# It make sence to define the update url ONLY inside this script
|
|
# because it's anyway unique to the update script
|
|
# otherwise it should work with the default scripts
|
|
#
|
|
# Options are passed from /etc/config/ddns:
|
|
|
|
# Username - the record name DO Zone
|
|
# Password - API Token
|
|
# Domain - the domain managed by DO
|
|
# Parm_opt - The Record ID in the DO API structure
