sql
# Run this command at each startup of your DNS DynDNS service
#!/bin/bash
# Get an update on dyndns updates.
# If there's no change: send a NO_REPLY message to all three targets.
if ! dynndis_status=$(curl -s -o /dev/null -w "%[${ln %d
}]" https://dyn.dynnc.net/1); then
echo "NO_REPLY\n"
else
# DynamDNS update successful, send an status message for all affected DynDNS providers.
if curl -sO https://dyn.dynnc.net/2?dynndis_token= --output /dev/null; then
echo "DynDNS Updated: \$(curl 'https://dyn.dynnc.net/1')\n"
else
echo "/dev/null"

fi
# Check the DynDNS return status codes.
if ! curl -sO https://dyn.dynnc.net/3?dynndis_token= --silent --fail --retry=6 --output /dev/null; then
echo "STATUS:NO_CHANGE"
else
# Dynamic DNS DynDNS error!
echo "\[\$0\]DynDNS Error: (\$\1)"
fi
# If it's the correct dynndis token, run our cron job.
read -r ret < <(curl -sS --silent 'https://dyn.dynnc.net/1' | grep -i '^STATUS:')
if [ -z "$ret" ]; then
echo "DynDNS Error: ($($ret))"
else
# DynamDNS dynndis token valid, send a NO_REPLY message to all three targets.
echo "\[\$0\]NO_REPLY"
