  • Method Summary

    Modifier and Type Method Description
    Baseboard getBaseboard()
    Get the computer system baseboard/motherboard.
    Firmware getFirmware()
    Get the computer system firmware/BIOS.
    java.lang.String getManufacturer()
    Get the computer system manufacturer.
    java.lang.String getModel()
    Get the computer system model.
    java.lang.String getSerialNumber()
    Get the computer system serial number, if available.

  • Method Details

    • getManufacturer

      java.lang.String getManufacturer()
      Get the computer system manufacturer.
      Returns:
      The manufacturer.

    • getModel

      java.lang.String getModel()
      Get the computer system model.
      Returns:
      The model.

    • getSerialNumber

      java.lang.String getSerialNumber()
      Get the computer system serial number, if available.

      Performs a best-effort attempt to retrieve a unique serial number from the computer system. This may originate from the baseboard, BIOS, processor, hardware UUID, etc.

      This value is provided for information only. Caution should be exercised if using this result to "fingerprint" a system for licensing or other purposes, as the result may change based on program permissions or installation of software packages. Specifically, on Linux and FreeBSD, this requires either root permissions, or installation of the (deprecated) HAL library (lshal command). Linux also attempts to read the dmi/id serial number files in sysfs, which are read-only root by default but may have permissions altered by the user.

      Returns:
      the System Serial Number, if available, otherwise returns "unknown"

    • getFirmware

      Firmware getFirmware()
      Get the computer system firmware/BIOS.
      Returns:
      A Firmware object for this system

    • getBaseboard

      Baseboard getBaseboard()
      Get the computer system baseboard/motherboard.
      Returns:
      A Baseboard object for this system
