Restoring the Kerio Operator default configuration using a USB flash-drive

Kerio Technologies provides a set of tools for solutions for situations in which it is not possible to connect to Kerio Operator on a network and administer it through the Kerio Operator Administration web interface.

These tools are designed to run from a USB flash-drive.

For complete system recovery a USB flash-drive with capacity of at least 1 GB is required. For restoring the default configuration, a capacity of 256 MB is needed.

Should any issues arise (for example, if Kerio Operator fails to work even after you perform a complete system recovery) please contact our technical support.

Restoring default configuration

The factory settings of Kerio Operator can be recovered with the file kerio-operator-factory-reset.

Factory settings recovery includes removal of all configuration data including activation and the statistics database.

This USB tools is designed for a single use so that an 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 file can be removed from the flash-drive.

  1. Insert a USB flash-drive to your computer (256 MB or larger) into a USB port on your computer.
  2. Make sure that only one partition with file system FAT16 or FAT32 (VFAT ) is created on the flash-drive. The USB drive must not be formatted by file system NTFS or ext2, ext3, or ext4.
  3. Save the kerio-operator-factory-reset file to the flash-drive.
  4. Switch off Kerio Operator.
  5. Plug the USB flash-drive into one of the USB ports of your Kerio Operator.
  6. Switch on Kerio Operator.
  7. For factory settings recovery to take effect, Kerio Operator is restarted automatically.
  8. To connect to Kerio Operator, set the following TCP/IP parameters on your computer:
  • IP address: 10.10.10.2
  • Subnet mask: 255.255.255.0
  1. Use the web browser of the connected computer to enter the following address: https://10.10.10.1:4021/admin
  2. Set the administrator password, login to the product administration and configure Kerio Operator Box as needed.

WARNING

If the steps above do not work, try another flash-drive. Different Kerio Operator Box models require different USB drive formats:

Complete system recovery

Kerio Operator can be completely recovered with the kerio-operator-rescue file. Within the system recovery, all configuration data including activation and the statistics database will be completely rewritten. Therefore the device will have to be reactivated and reconfigured for further use.

Before applying complete system recovery, it is highly recommended to retest connection to Kerio Operator after attempting for restore of the factory settings.

Preparing flash-drive for system recovery

For complete system recovery, Kerio Operator Box first needs to introduce operating system from USB drive. File kerio-operator-rescue is an image of an installation drive 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.

  4. Use command sudo fdisk -l to detect the USB flash-drive name (e.g. /dev/sdb).
  5. Save the kerio-operator-rescue file to the USB flash-drive using command: sudo dd if=rescue.img of=/dev/sdx bs=1M and replace rescue.img with the real file name and /dev/diskX with the real appliance. It is necessary to enter the physical device (e.g. /dev/sdx), not only a partition (e.g. /dev/sdx1).
  6. Use command sudo sync to guarantee finishing of all drive operations.
