当我安装macchanger软件包时，我将其设置为每次接口关闭时更改 mac 地址。但我注意到我的 IP 地址没有改变。所以我检查了我的mac地址。
连接到路由器时
ip addr
1: wlo1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
link/ether ab:cd:ef:01:23:45 brd ff:ff:ff:ff:ff:ff
inet 192.168.0.7/24 brd 192.168.0.255 scope global dynamic noprefixroute wlo1
valid_lft 7175sec preferred_lft 7175sec
当 Wi-Fi 被禁用时
ip addr
1: wlo1: <BROADCAST,MULTICAST> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
link/ether 67:89:ab:cd:ef:01 brd ff:ff:ff:ff:ff:ff permaddr ab:cd:ef:01:23:45
altname wlp0s20f3
重新启用 Wi-Fi 时
ip addr
1: wlo1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
link/ether ab:cd:ef:01:23:45 brd ff:ff:ff:ff:ff:ff
altname wlp0s20f3
重新连接到路由器时
ip addr
1: wlo1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
link/ether ab:cd:ef:01:23:45 brd ff:ff:ff:ff:ff:ff
inet 192.168.0.7/24 brd 192.168.0.255 scope global dynamic noprefixroute wlo1
valid_lft 7160sec preferred_lft 7160sec
当我在 Wi-Fi 禁用时尝试更改 Mac 地址时
macchanger -r wlo1
Current MAC: 67:89:ab:cd:ef:01 (unknown)
Permanent MAC: ab:cd:ef:01:23:45 (unknown)
New MAC: 23:45:67:89:ab:cd (unknown)
当我在 Wi-Fi 已打开但未连接时尝试手动更改 Mac 地址时
macchanger -r wlo1
Current MAC: 67:89:ab:cd:ef:01 (unknown)
Permanent MAC: ab:cd:ef:01:23:45 (unknown)
[ERROR] Could not change MAC: interface up or insufficient permissions: Device or resource busy
当我尝试在连接到 Wi-Fi 时手动更改 MAC 地址时
macchanger -r wlo1
Current MAC: ab:cd:ef:01:23:45 (unknown)
Permanent MAC: ab:cd:ef:01:23:45 (unknown)
[ERROR] Could not change MAC: interface up or insufficient permissions: Device or resource busy
如您所见，每当我重新连接到 Wi-Fi 时，更改就会恢复。我怎样才能让它坚持下去？
