### Configuration File: ha.cf

The ha.cf file is the HeartBeat main configuration file consisting of a configuration parameters list. A sample follows:

    bcast eth1

    keepalive 2

    warntime 10

    deadtime 30

    initdead 120

    udpport 694

    nice_failback on

    node EY-FTP1         ##  This is your server 1

    node EY-FTP2         ##  This is your server 2

    ping 192.168.38.1    ##  This is a pingable address

The “node” definitions allow HeartBeat to identify the two servers that form the High Availability cluster. The last entry is how HeartBeat confirms its network connectivity. If the “ping” fails to operate correctly, HeartBeat assumes that although it is functioning correctly, it has lost connectivity to the network. In this case, HeartBeat proceeds to interchange to the other node/server.
