Linux Devices Share a UUID

Linux devices are showing as duplicates or share a UUID

Cause

When Automox generates a UUID for a device, if more than 40% of the device variables match another known device, Automox will then assign both devices the same UUID, which can (and often does) cause problems.

Automox generally uses these variables when generating a UUID for a device:

const HARDWARE_ID_UUID = 'uuid'; // windows
    const HARDWARE_ID_MACHINE_ID = 'machine-id'; // non-windows
    const PROCESSOR_HASH = 'processor-hash';
    const MEMORY_HASH = 'memory-hash';
    const BIOS_HASH = 'bios-hash';
    const SYSTEM_HASH = 'system-hash';
    const HOSTNAME_INFO = "hostname-info";
    const IP_ADDRESS_ID = 'ipaddress-info';
    const MAC_ADDR_INFO = 'macaddr-info';
    const DISK_INFO = 'disk-info';
    const MINIMUM_MATCH_PERCENT = 40;

So, each device needs to be under a 40% match for those variables, with any other known device.

Answer

• Running these commands can reset the machine-id:

  • sudo rm /etc/machine-id

  • sudo systemd-machine-id-setup
