This topic provides instructions on how 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 appliance.
  • Network names for all virtual appliances, if you are creating a cluster.
  • DNS or host information.

Note: A script will run immediately upon logging on, asking for the Security Analytics server IP address. Press Enter, with no IP address, or Ctrl-C to break out of this script. Once the current appliance is completely setup and the Security Analytics server is online and ready to accept appliances, enter the Security Analytics IP address at this prompt by logging off and logging back on.

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

To configure the network:

  1. Edit the /etc/sysconfig/network-scripts/ifcfg-eth0 configuration file as shown below with the appropriate IP address, netmask and gateway. (The reason for manual network configuration is that the Security Analytics OVF automatic network configuration option does not successfully set all network settings at this time.) BOOTPROTO should be set to NONE or STATIC to avoid automatically defaulting to DHCP.

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

  3. (Optional) Edit the /etc/resolv.conf file and set the preferred DNS servers the appliance should use.

  4. Configure the hostname. If you configured the DNS server entries so that the DNS server can resolve the Security Analytics appliances, you can skip this step. Otherwise, configure the /etc/hosts file as follows:

    1. Change all references to the default appliance hostname to match your chosen hostname.
    2.  Add the line:    <your-appliance-ip-address> <your-appliance-hostname>

      where <your-appliance-ip-address> is the IP address of your machine, and where <your-appliance-hostname> is the name of your appliance.

    3. Add the line:

      <your-Security-Analytics-Server-ip-address> <your-Security-Analytics-appliance-hostname>

      where <your-Security-Analytics-Server-ip-address> is the IP address and <your-Security-Analytics-appliance-hostname> is the name of your Security Analytics appliance.

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

    service network restart

  6. Progress messages are displayed as the adapter restarts.
