It sounds like HA may be the wrong tool for what you want. You might be better off with some type of monitoring/notification tool such as Nagios. Those tools can do more than just ping, they can connect to the web server and verify that it is operating properly. While it might be possible to make the cluster software work over a WAN, it was never really designed to operate that way. Ideally you need more than one connection between nodes and a way for one node to fence the other (STONITH) in order for the cluster software to work properly. --Greg _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
