NAMEocf_heartbeat_dnsupdate − IP take−over via dynamic DNS update

DESCRIPTIONThis resource agent manages IP take−over via dynamic DNS updates.

SUPPORTED PARAMETERShostname The hostname whose IP address will need to be updated. (unique, required, string, no default) ip IP address to set. (required, string, no default) ttl Time to live, in seconds, for the DNS record. This affects how soon DNS updates propagate. It should be a reasonable compromise between update speed and DNS server load. If using booth, the ticket timeout is a good start. (optional, integer, default 300) keyfile The file containing the shared secret needed to update the DNS record. Please see the nsupdate man page for the exact syntax. (optional, string, no default) server Which DNS server to send these updates for. When no server is provided, this defaults to the master server for the correct zone. (optional, string, no default) serverport Port number on the DNS server. Note: due to a limitation in the nsupdate command, this option will only take effect if you also specify the DNS server! (optional, integer, default 53) nsupdate_opts Additional options to be passed to nsupdate. (optional, string, no default) unregister_on_stop Whether or not to actively remove records on stop. This is not needed for normal operation, since the site taking over the IP address will delete all previous records. (optional, boolean, default false)

SUPPORTED ACTIONSThis resource agent supports the following actions (operations): start Starts the resource. Suggested minimum timeout: 30s. stop Stops the resource.
