About "host ping file"

[Manuel Cardeñas]

	Hello!	(and excuse my poor english)

	I'm building a firewall with 2 nodes in HA. I saw in that url:

Set up a "host ping file" on each node, containing IP addresses or 
resolvable names of other machines in the network. If a IP subsystem 
failure is suspected, the machines mentioned in this file will be pinged. 
If answers are received, the local IP subsystem is fine, if not, it is 
down. Especially when the nodes have only one network adapter (this makes 
only sense for rotating resource groups) this is the only way to tell a 
network failure from an adapter or node failure.

	I use a interface for inbound traffic and other interface for outbound 
traffic. I'm using vlan tagging.

	Now, if I disconnect the wire of an interface, heartbeat don't realize.

	I'm using "heartbeat-0.4.9.2-1" rpm package on RedHat 7.2. Is "ipfail" 
included?

	Another question... Is possible switch _ONLY_ one service from node 1 to 
node 2.

	Thanks in advanced.

	ciao.
