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)
