Personal DDNS client with Digital Ocean Networking DNS as backend.
We have services like DynDNS, No-IP to access PCs remotely. But do we need them? This project is your own DDNS solution and will work for free (thanks to Digital Ocean Networking DNS).
From Wikipedia
Dynamic DNS (DDNS or DynDNS) is a method of automatically updating a name server in the Domain Name System (DNS), often in real time, with the active DDNS configuration of its configured hostnames, addresses or other information.
Put binary in /usr/local/bin.
And start it as:
ddnsOr you can start ddns in background:
ddns > /dev/null 2>&1 &You can download binary for your OS from releases page.
ATTENTION! Currently tested on Linux and macOS.
Run ddns -h, to see help. It will output:
Usage of ddns:
-check-period duration
Check if IP has been changed period (default 5m0s)
-conf-file string
Location of the configuration file (default "$HOME/.ddns.yml")
-req-timeout duration
Request timeout to external resources (default 10s)
Configuration should be supplied. By default it is read from $HOME/.ddns.yml.
You need to setup your domain in Digital Ocean Networks panel.
