I am about to configure two Nagios servers with one being a hot-standbye or failover unit. It will periodically check the active Nagios server and will need to steal its IP addresses in the case of failure.
My first instinct it to just script this using bash and cron, which should be fairly trivial. Is there a better utility for taking over another servers IPs? Perhaps one that would allow the previously active server to steal it's IPs back when it comes back online.
