# asuswrt (https://github.com/RMerl/asuswrt-merlin) project
# It updates the ddns name from freedns.afraid.org

# the base64 key part from the update url  you get from freedns.afraid.org
# don't forget to copy/paste the "=" if it exists at the end.

# use openssl instead of `wget` since we need https connections
# support https connections... and the `sleep 5` prevents
# openssl from closing the connection due to eof on stdin from
# just using `echo`
