dyndnscd is the dyndns client daemon. It is a daemon that continually polls for IP address changes an in the event of a change, triggers an IP address update. It is somewhat configurable.
You can find the latest version and the git repository of dyndnscd under the following URL: http://github.com/akrennmair/dyndnscd/
Run go get github.com/akrennmair/dyndnscd, then run it like this: dyndnscd -f configfile.yaml
The configuration is a YAML file, consisting of a list of configuration
sections. Every section defines the IP polling mechanism with a type
(allowed values: device, ipbouncer). The device type regularly polls the
IPv4 address of a network device (specified by the configuration key device),
while the ipbouncer regularly polls the IPv4 address by calling a bouncer
URL. A bouncer URL returns the client's IP address as the only content of the
response body, and is configured with the configuration key bouncer_url.
The URL update is configured with the configuraton key update_url. Simply
write <ip> (no quotes) where the client IP shall be inserted. dyndnscd will
replace it with the IP and will do a GET request on the resulting URL.
To configure the polling interval, use the configuration key interval (defines
the minimum amount of time between two polling attempts). If no interval is specified,
it defaults to 60 seconds.
