NAME

       ocf_heartbeat_dnsupdate - IP take-over via dynamic DNS update

SYNOPSIS

       dnsupdate [start | stop | status | monitor | meta-data | validate-all]

DESCRIPTION

       This resource agent manages IP take-over via dynamic DNS updates.

SUPPORTED PARAMETERS

       hostname
           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)
