Creating Virtual Network Interface for HA-OSCAR Primary Server
First select Detection channel configuration shown in Figure 10, and navigate
into the corresponding screen shown in Figure 11. Initially, there should be
three network interfaces:
lo, all created during OSCAR and
HA-OSCAR installation. Add virtual network interfaces for
clicking on the Add a new interface button in Figure 12. Sample screens
(Figures 13 and 14) show how to add virtual network interfaces for

Building Detection Channel Information
After you create the virtual network interfaces, the next step is to define the previously created network interfaces for HA-OSCAR (health) detection channels. Access the detection channel configuration from the HA-OSCAR Webmin screen shown in Figure 15. When you've made your selection, enter the network interface information in the form shown in Figure 15.

Optional Steps for Managing Services Configuration
HA-OSCAR provides a useful default set of monitoring policies. However, users can add new services and change monitoring parameters. We do recommend this option for advanced users.
