Method Detail

getManufacturer

public String getManufacturer()

Get the computer system manufacturer.

Specified by:

getManufacturer in interface ComputerSystem

Returns:

The manufacturer.

getModel

public String getModel()

Get the computer system model.

Specified by:

getModel in interface ComputerSystem

Returns:

The model.

getSerialNumber

public 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.

Specified by:

getSerialNumber in interface ComputerSystem

Returns:

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