phuslu / ddns Goto Github PK

I want to run ddns as a daemon, in systemd so my DNS can be updated in real time.

You can implemente this feature by add a option --daemon and run your check & update code once in a while.

When I use ddns to update namesilo, I get an error. The ip address has not been successfully updated.

The reason is that namesilo must set ttl to more than 3600.So I modified the code of ddns and changed rrttl from namesile from 600 to 7207. The run ddns again, it was successful.

Sometimes we really need to visit a Internet service to get our IP address such as when we are in a LAN in a LAN in a LAN... But the other times when our server is exposed to the Internet we can get our IP address directly from ifconfig (or sudo ifconfig on fucking Debian). So additional Internet bandwith cost could be reduced.

There's some solution for getting local IP from command line: https://askubuntu.com/a/488916. However you can add an option to let users provide their command of getting IP.
