Thanks Giles. The host already runs linux heartbeat, and is in an active-passive ha cluster running bind, ldap and dhcpd. I wanted to add nagios to the mix. When setting this up it is usual to give each app a VIP address, and configure that on the active host. As I have configured nrpe clients to only allow checks from one IP - the nrpe checks needs to come from that IP address.
