Non-interactive mode opens up a new session per command, but the interactive shell maintains the same session until exited. In this example, we used the select command in interactive mode. To change the default controller, we use the bluetoothctl select command, passing the MAC address of the controller we want to connect to: # select 34:02:86:03:7C:F2Ĭontroller 34:02:86:03:7C:F2 pc-m Ĭontroller 34:02:86:03:7C:F2 pc-m #2

The default controller is the controller that will be operated on when we run a command. This command outputs information about the connected Bluetooth controllers, including their MAC addresses and what the default controller is. This would match any MAC address where the OUI, or first three bytes, are “aa:bb:cc”.Let’s use the bluetoothctl list command to get a list of connected Bluetooth controllers: $ bluetoothctl listĬontroller 00:1A:7D:DA:71:15 pc-m On queries and filters affecting MAC addresses, Kismet supports complete addresses or partial addresses with masking.Ī masked address resembles the syntax typically used for IP network masking: /.įor instance, to match only the OUI, a masked MAC of: "aa:bb:cc:00:00:00/ff:ff:ff:00:00:00" Typically, the the IEEE assigns each manufacturer a block of addresses with a common header (the OUI) and the manufacturer is responsible for creating unique identifiers within that block.įor datasources without a defined MAC address, Kismet will attempt to synthesize a MAC address from the unique data available. It is used to identify the device uniquely on a network.

The MAC address is a (theoretically) unique identifier given to each device at manufacture time. This allows multiple devices to have the same MAC under different PHY types this can be particularly important when using non-traditional PHY types like those derived from SDR captures, when the devices do not have an actual MAC address. The key is derived from the MAC address, but contains additional information about the PHY type. Devices are indexed two primary ways in Kismet:Ī key is unique for each device.
