Barracuda Spam Firewall

Troubleshooting

Basic Troubleshooting Tools

The ADVANCED > Troubleshooting page provides a suite of tools that help troubleshoot network connectivity issues that may be impacting the performance of your Barracuda Spam Firewall.

For example, you can test your Barracuda Spam Firewall’s connection to the Barracuda Networks update servers to make sure that it can successfully download the latest Energize Update definitions. You can also ping or telnet to other devices from the Barracuda Spam Firewall, perform dig/NS-lookup, TCP dump and perform a trace route from the Barracuda Spam Firewall to any another system.

Connect to Barracuda Support Servers

In the Support Diagnostics section of the ADVANCED > Troubleshooting page, you can initiate a connection between your Barracuda Spam Firewall and the Barracuda Networks Technical Support Center which will allow technical support engineers to troubleshoot any issues you may be experiencing.

Rebooting the System in Recovery Mode

If your Barracuda Spam Firewall experiences a serious issue that impacts its core functionality, you can use diagnostic and recovery tools that are available from the reboot menu (see below) to return your system to an operational state.

Before you use the diagnostic and recovery tools, do the following:

  • Use the built-in troubleshooting tools on the ADVANCED > Troubleshooting page to help diagnose the problem.
  • Perform a system restore from the last known good backup file.
  • Contact Barracuda Networks Technical Support for additional troubleshooting tips.

As a last resort, you can reboot your Barracuda Spam Firewall and run a memory test or perform a complete system recovery, as described below.

To perform a system recovery or hardware test:

  1. Connect a monitor and keyboard directly to your Barracuda Spam Firewall.
  2. Reboot the system by doing one of the following:
    - In the web interface: Go to the BASIC > Administration page, navigate to the System Management section, and click Restart.
    - At the front panel of the Barracuda Spam Firewall: Press the Power button on the front panel to turn off the system, and then press the Power button again to turn the system on.

    The splash screen displays with the following three boot options:

    Barracuda
    Recovery
    Hardware_Test
  3. Use your keyboard to select the desired boot option, and press the Enter key. You must select the boot option within three seconds after the splash screen appears. If you do not select an option within three seconds, the Barracuda Spam Firewall starts up in Normal mode (first option). For a description of each boot option, refer to Reboot Options below.

 To stop a hardware test, reboot your Barracuda Spam Firewall by pressing the Ctrl-Alt-Del keys.
