How to change the numbers of the glands of the computer in Ubuntu?

Question

linux

Tell me, is there any software for replacing MAC, HWID, SID, and other system identifiers for Ubuntu?

Answer 1

Mac changes just in the network settings

Answer 2

Hardware-sewn numbers do not change, except for those sewn into the firmware (for example, for mothers). Softovo can change the MAC network card and blue-toothed devices.

Answer 3

It is not entirely clear why to change, but the poppy address of the network card is changed regularly with the ifconfig and ip commands, read man on them.
And the serial number of your motherboard is a simple user and cannot read it, let alone transfer it somewhere:
dmidecode
# dmidecode 3.0
/sys/firmware/dmi/tables/smbios_entry_point: Permission denied
Scanning /dev/mem for entry point.
