Updating a Linux Actor's Network Settings

If your network changes after installing your Actor, you can update the Actor's networking using the vsetnet command. If you're managing multiple interfaces on the same subnet for a Network Actor, see Using Multiple Interfaces on the same Subnet before running vsetnet.

When you run vsetnet on an Actor installed using the OVA appliance, you decide whether you want to manually manage the Actor's network configuration files or have the Validation Platform manage the files. When deciding which option is best, Items to consider include:

• The Security Validation Platform managing the network configuration improves network reliability and stability.
• This setting can be modified by rerunning vsetnet for the Actor.
• When enabled, this setting overwrites any changes that you've made to the Actor's network configuration files.

Actors on Linux systems cannot be completely managed by Security Validation. However, you can use the platform to update the network configuration files for those Actors. The Validation Platform cannot manage or update the network configuration files for any endpoint Actor or Actors on Linux systems.

1. Log into the Actor from the command line.

2. Run the following command to select the interfaces (all) and update the network configuration. If you did not update the PATH, use the first command, updating the path if necessary.

   $ sudo /opt/apps/verodin/node/node/scripts/vsetnet

   or

   sudo vsetnet

   This step walks you through configuring the networking. If you choose to set it up manually, note the following:

   • RHEL version earlier than 8: For each interface you use you need its IP address, netmask, gateway, and DNS information.
   • RHEL or CentOS versions 8 - 9: You only select the interface and you’re responsible for configuring the networking.
     If you're managing multiple interfaces on the same subnet, see Using Multiple Interfaces on the same Subnet before running vsetnet. If you’re rerunning vsetnet and are prompted "Will Verodin control the network configuration files?", saying yes means that the platform manages the networking and overwrites any changes you previously made to the network configuration files.

3. After completing configuration, confirm that the IP settings have been changed.

   ifconfig

4. Launch the Director.

5. Select Environment > Actors.
6. Locate the Actor that you want to configure, open its Action menu, and click Edit.
7. Click Refresh Actor Info.
