Diagnostic tool for Kerio Operator Box V series

Kerio Technologies provides a tool for diagnosing hardware problems with the Kerio Operator Box NG series. This tool collects crucial information for the Kerio Technologies technical support. It is designed to be run from a USB flash drive.

You need a USB flash drive with a capacity of at least 256 MB.

The diagnostic tool is designed for a single use so that the operation will not repeat if you restart with the flash drive still in the USB port. Once you perform the operation, the content cannot be reused, so the files can be removed from the flash drive.

Creating the diagnostic flash drive

The diagnostic tool is an image of an installation disk and must be saved directly on the physical device. Follow the instructions for your client system below.

Microsoft Windows

1. Insert the flash drive to your computer (256 MB or larger) into a USB port on your computer.

2. Download and unpack Image Writer (it does not require installation).
3. Download the diagnostic tool 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.

2. Download the diagnostic tool 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 diagnostic tool file on the flash drive using this command: sudo dd if=usbdiag.img of=/dev/sdx bs=1M (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.

2. Download the diagnostic tool 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).

5. Use the command sudo diskutil unmountDisk /dev/diskX to eject the flash drive.
6. Save the diagnostic tool file on the USB flash drive using this command: sudo dd if=usbdiag.img of=/dev/disk1 bs=1m (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 Operator Box.
2. Plug the USB flash drive into one of the USB ports of your Kerio Operator Box.
3. Switch on Kerio Operator Box to run the diagnostic test. The diagnostic test may take some time (approximately 60 minutes).
4. Switch off Kerio Operator Box and eject the USB flash drive.

Test results processing

Reinsert the flash drive into the USB port.

Find the partition called KerioDiag on the flash drive. It contains the file with test results.

Send this file to Kerio Technologies technical support, and optionally provide a description of the nonstandard behavior of your Kerio Operator Box.

Recovering USB flash drive for further use

To reuse your flash drive, you will need to reformat it to remove the partitions. For more information refer to Restoring the Kerio Operator Box V series default configuration using a USB flash drive.
