# Dongled version

The Master library is encrypted and requires a dongle to execute. The following dongles are supported:

- USB dongle
- ASIC dongle
- Virtual dongle using a WibuCmRaU file

## Licensing using a virtual WibuCmRaU File on Linux

To create a virtual dongle using a WibuCmRaU file on a Linux machine, the following steps are required:

- Download the codemeter package from Wibu website and install it on the linux machine:
- Import the LIF file provided by acontis
  : ```batch
    cmu --import --file *.WibuCmLIF
    ```
- List the Wibu licenses, to get the serial number
  : ```batch
    cmu --list
    ```
- Use the serial number to generate a WibuCmRaC file
  : ```batch
    cmu --serial your_serial_number --context 6001978 --file *.WibuCmRaC
    ```
- Send the WibuCmRaC to acontis and acontis will provide a WibuCmRaU file.
- Import the WibuCmRaU file
  : ```batch
    cmu --import --file *.WibuCmRaU
    ```

## Maintain the license after a linux image update

In case of a complete Linux image update, the following steps are required:

- Make a backup of the WibuCmRaU file and the following folder /var/lib/Codemeter/CmAct from the old image.
- On the new image install Codemeter
- Restore the 6001978_\* files from /var/lib/Codemeter/CmAct
- Change the user rights of the 4 files to daemon
  : ```batch
    sudo chown daemon:daemon 6001978_*
    ```
- Import the WibuCmRaU backup file
  : ```batch
    cmu --import --file *.WibuCmRaU
    ```
