dyndnsd-client

Client for the dyndnsd daemon. Set up dyndnsd first, otherwise this is useless.

Use

Set up a cron entry to run the program periodically, or manually call it when your IP address changes. The program accepts a single argument, -config, pointing to a config.json file that handles everything. A sample config.json is provided in the form of config-sample.json.

Configuration Options

• username: daemon username
• password: daemon password
• protocol: http or https, preferably the latter
• host: IP or hostname of dnydnsd instance
• port: port dyndnsd is listening on
• path: path to dnydnsd daemon, typically nic/update
• dns_hostname: the nsd zone to update
• ipv4_endpoint: GET-accessible endpoint that returns an IPv4 IP address as a string; when in doubt, use http://whatismyip.akamai.com/
• ipv6_endpoint: GET-accessible endpoint that returns an IPv6 IP address as a string; when in doubt, use http://ipv6.whatismyip.akamai.com/
• ipv6_use_prefix: if running multiple instances on the same network, use only the IPv6 prefix, omitting the instance portion of the address; this greatly reduces unnecessary nsd updates

Proxying via nginx

dnydnsd doesn't support HTTPS, so using nginx as an HTTPS proxy is recommended. Sending a username and password over an unsecured connection should be avoided if possible.
