Complete the following steps to configure the network of the Virtual Appliance.

Prerequisites

Make sure that you have:

  • Network IP addresses, netmask, and gateway IP addresses for the virtual host.
  • Network names for all virtual hosts, if you are creating a cluster.
  • DNS or host information.

Note: As soon as you log on, a script runs that asks you for the Security Analytics Server (SA Server) Host IP address. Press Enter, with no IP address, or Ctrl-C to break out of this script. After you complete the current host setup and the SA Server Host is online and ready to accept hosts, enter the Security Analytics IP address at this prompt by logging off and logging back on.

Procedure

Perform the following steps for all virtual hosts to get them on your network.

To configure the network:

  1. Edit the /etc/sysconfig/network-scripts/ifcfg-eth0 configuration file with the appropriate IP address, netmask, and gateway.

    Note: You need to configure the network manually because the Security Analytics OVF automatic network configuration option does not successfully set all network settings at this time. You should set BOOTPROTO to NONE or STATIC to avoid automatically defaulting to DHCP.

  2. Edit the /etc/sysconfig/network file and set the host Hostname.

  3. (Optional) Edit the /etc/resolv.conf file and set the preferred DNS servers that you want the host to use.

  4. If you:

    • Configured the DNS server entries so that the DNS server can resolve the Security Analytics hosts, you can skip this step.
    • Have not configured the DNS server entries so that the DNS server can resolve the Security Analytics hosts, complete the following steps to configure the /etc/hosts file.

      1. Change all references to the default host hostname to match your chosen hostname.
      2. Add the line:

        your-host-ip-address>your-host-hostname

        where your-host-ip-address is the IP address of your machine, where your-host-hostname is the name of your host.

      3. Add the line:

        your-SA-server-host-ip-address>your-SA-server-host-hostname

        where your-SA-server-host-ip-address is the IP address
        and your-SA-server-host-hostname is the name of your Security Analytics server host.

  5. Restart the network adapter and type the following command:

    service network restart

    Progress messages are displayed as the adapter restarts.
