Diagnostic Tool for Kerio Control Legacy boxes

Overview

GFI/Kerio provide a tool for diagnosing hardware problems with the Kerio Control Box. This tool collects crucial information for technical support. It is designed to run from a USB flash drive. You need a USB flash drive with a capacity of at least 256 MB.

Note: for the detailed legacy hardware list, please refer to EOL for Legacy Hardware Support in Kerio Control.

The diagnostic tool is designed for a single-use. An operation does not repeat if you restart with the flash drive still in the USB port. Once you perform the operation unplug the flash drive.

Solution

 

Creating the diagnostic flash drive

Microsoft Windows
  1. Insert the flash drive into a USB port on your computer. All data on the flash drive will be completely overwritten, so be sure to save any files you need elsewhere.
  2. Download and unpack Image Writer (it does not require installation).
  3. Download the kerio-control-usbdiag file.
  4. In Image Writer, find the file, select your flash drive and click Write.
  5. Eject the flash drive securely and remove it from your computer.
Linux
  1. Insert the flash drive into a USB port on your computer. All data on the flash drive will be completely overwritten, so be sure to save any files you need elsewhere.
  2. Download the kerio-control-usbdiag file.
  3. Run the terminal (console).
  4. Use the command sudo fdisk -l to detect the USB flash drive name (e.g. /dev/sdx).
  5. Save the kerio-control-usbdiag file on the flash drive using this command: sudo dd if=usbdiag.img of=/dev/sdx bs=1M where you replace usbdiag.img with the real file name and /dev/sdx with the actual device name. You must enter the physical device (e.g. /dev/sdx), not the partition (e.g. /dev/sdx1).
  6. Use the command sudo sync to ensure that all disk operations finish.
  7. Eject the flash drive securely and remove it from your computer.
Mac OS X
  1. Insert the flash drive into a USB port on your computer. All data on the flash drive will be completely overwritten, so be sure to save any files you need elsewhere.
  2. Download the kerio-control-usbdiag file.
  3. Run the terminal: Applications > Utilities > Terminal.
  4. Use the command sudo diskutil list to detect the USB flash drive name (e.g. /dev/diskX or /dev/DiskY). Note that this is case sensitive.
  5. Use the command sudo diskutil unmountDisk /dev/diskX to eject the flash drive.
  6. Save the kerio-control-usbdiag file on the USB flash drive using this command: sudo dd if=usbdiag.img of=/dev/disk1 bs=1m where you replace string usbdiag.img with the real file name and /dev/diskX with the real device.
  7. Eject the flash drive securely and remove it from your computer.

 

Using the diagnostic flash drive

  1. Switch off Kerio Control Box.
  2. Plug the USB flash drive into one of the USB ports of your Kerio Control Box.
  3. Switch on Kerio Control Box.
  4. After approximately 2 minutes Kerio Control Box beeps three times with different frequencies (1000, 5000, 1500). This means that the operating system has been introduced and the diagnostic test has started. If the device does not beep within the following 10 minutes, the test has failed. In that case switch off the device, eject the USB flash drive, and send the diagnostic information to Kerio Technologies technical support.

    Note: Kerio Control uses standard beep Linux library.

  5. The test starts with 10 beeps and runs for about 60 minutes — a 40-minute memory test and a diagnostic test. If you want to skip the memory test, press any key during the ten-beep interval. Once the test is finished, Kerio Control Box starts beeping every 30 seconds.
  6. Switch off Kerio Control Box and eject the USB flash drive.

Test results processing

  1. Reinsert the flash drive into the USB port.
  2. Find the partition called KerioDiag on the flash drive. It contains the file with the test results.
  3. Send this file to Kerio Technologies technical support and optionally describe the problem of your Kerio Control Box.
