Changing Network Settings in a Single NIC Configuration

The following procedure describes how to change the basic network information for the node if there is only one NIC configured on the VM. If you are using multiple NICs, see Configuring Multiple NICs on an Existing KeyControl Node.

Before You Begin 

If you need to change the KeyControl node's hostname or IP address and the node is part of a cluster, you need to remove the node from the cluster first.

Procedure 

  1. Use your hypervisor to access one of the VMs in which KeyControl is running, then log into the KeyControl VM console as htadmin .

    KeyControl displays the HyTrust KeyControl System Console TUI (Text-based User Interface).

  2. From the HyTrust KeyControl System Console, select Manage Network Settings.

  3. If you want to view the current settings, select Show Current Network Configuration.

    Note: While it appears that you can change the information on this page, KeyControl does not save your changes when you select OK. Therefore you do not need to worry about unintentional changes.

  4. If you want to change the settings, select Change Current Network Configuration.
  5. KeyControl warns you that you may need to reauthenticate this node if you change the IP address or hostname. Press Enter to acknowledge this message.

  6. On the HyTrust SecureOS Network Configuration page, select the type of network you want to use for communication between the KeyControl nodes in the cluster and between the KeyControl nodes and the Policy Agents. You can select:

    • Use DHCP — Communication uses Dynamic Host Configuration Protocol, but you must still specify a static IP address for the KeyControl node. When you select this option, KeyControl displays a message with the current IP address and reminds you again that changes to the IP address may require authentication. Select OK and press Enter to acknowledge this message and continue.
    • Custom Configuration — KeyControl gathers the current network settings and displays them on the Network Configuration page.

    • VLAN Configuration — Communication uses a virtual LAN. Type the VLAN ID at the prompt, then select OK and press Enter.

  7. On the Network Configuration screen, review any network information the wizard automatically gathered and make any required additions or modifications. While you do so, keep in mind:

    • If this node is part of a cluster, you should not change the hostname or IP address for the node.
    • To enter multiple DNS addresses, separate them with a comma. For example, you could enter 192.168.162.2,192.168.162.3.
    • For all network types, the NTP Servers configuration defaults to a set of pooled servers provided by ntp.org.  This default is set by the operating system.
  8. When you are finished, select OK and press Enter.
