Linux-改變網卡的Mac Address

00 前置

• 檢視網卡正在使用的Mac Address: $ iw dev
• 主要會動到的部分
  1. 修改NetworkManager設定檔: /etc/NetworkManager/conf.d/mac.conf
  2. 修改完成後，請重啟NetworkManager，使設定生效: $ sudo systemctl restart NetworkManager

01 使用隨機產生Mac Address

[device]
wifi.scan-rand-mac-address=yes
ethernet.scan-rand-mac-address=yes

[connection]
ethernet.cloned-mac-address=random
wifi.cloned-mac-address=random

02 使用特定Mac Address

[device]
wifi.scan-rand-mac-address=no
ethernet.scan-rand-mac-address=no

[connection]
ethernet.cloned-mac-address=[NEW_MAC1]
wifi.cloned-mac-address=[NEW_MAC2]

03 不修改+使用原機的Mac Address

[device]
wifi.scan-rand-mac-address=no
ethernet.scan-rand-mac-address=no
