Diagnostic tool for Kerio Operator Box

Kerio Technologies provides diagnostic tool for diagnose hardware problems with the Kerio Operator Box, which elicits crucial information for the Kerio Technologies technical support. The tool is designed for use from a USB flashdisk.

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

The diagnostics tool is designed for a single use to avoid unexpected repetition of the operation upon the next restart in case that the flashdisk has not been dismounted. This implies that once you perform the operation, the disk content cannot be used again and the files can be removed.

Using a diagnostic USB tool

If you need the USB diagnostic tool, download and use the diagnostic tool.

Creating diagnostic flashdisk

The diagnostic tool is an image of an installation disk and must be saved directly on the physical device (similarly as in case of burning ISO images on CD). Please follow the instructions according to your client system.

Microsoft Windows

1. Mount the USB flashdisk to your computer. If necessary, back up files saved on the disk. The flashdisk data will be rewritten completely!
2. Download and unpack Image Writer (it does not require installation).
3. Download file the diagnostic tool file.
4. In application Image Writer, look up this file, select your flashdisk and click on Write.
5. Remove the disk securely and unplug it from your computer.

Linux

1. Mount the USB flashdisk to your computer. If necessary, back up files saved on the disk. The flashdisk data will be rewritten completely!
2. Download the diagnostic tool file.
3. Run the terminal (console).
4. Use command sudo fdisk -l to detect the USB flashdisk name (e.g. /dev/sdb).
5. Save the diagnostic tool file on this device by using the following command:

sudo dd if=usbdiag.img of=/dev/sdx bs=1M

Replace string with:

usbdiag.img by the real file name and /dev/sdx by the real device. It is necessary to enter the physical device (e.g. /dev/sdx), not only a fragment (for example, /dev/sdx1).

6. Use command sudo sync to guarantee finishing of all disk operations.
7. Unplug the USB disk from your computer.

Mac OS X

1. Mount the USB flashdisk to your computer. If necessary, back up files saved on the disk. The flashdisk data will be rewritten completely!
2. Download the diagnostic tool file.
3. Run the terminal (Applications > Utilities > Terminal).
4. Use command sudo diskutil list to detect the USB flashdisk name (e.g. /dev/diskX or /dev/DiskY — watch the letter case).
5. Use command sudo diskutil unmountDisk /dev/diskX to unmount the disk.
6. Save the diagnostic tool file on the USB disk by using the following command:

sudo dd if=usbdiag.img of=/dev/disk1 bs=1m

Replace string with:

usbdiag.img by the real file name and /dev/diskX by the real device.

7. Unplug the USB disk from your computer.

Using diagnostic flashdisk

1. Switch off Kerio Operator Box.
2. Plug the USB flashdisk into one of the USB ports of your Kerio Operator Box.
3. Switch on Kerio Operator Box.
4. Approximately after two minutes Kerio Operator Box beeps three times. This means that the operating system has been introduced and the diagnostic test has just been started. If the device does not beep within the following 10 minutes, the test has failed. In such case switch off the device, unplug the USB flashdisk and send diagnostic information the

   Kerio Technologies

   technical support (see below).
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 Operator Box and unplug the USB flashdisk.

Test results processing

Plug the USB flashdisk to your computer again. There is a partition called

KerioDiag

on the disk. This partition includes the file with test results.

Please send this file to the Kerio Technologies technical support and possibly provide a description of the non-standard behavior of your Kerio Operator Box.
