我正在尝试设置 cron 以在夜间(从 23:00 到 8:00)关闭 Raspberry Pi 上的网络。
问题是这些命令都不能完成这项工作:
$ sudo service networking stop
$ sudo ifconfig eth0 down
$ sudo ifdown eth0
从输出来看,该命令似乎有效,但接口仍然有效(我可以ping 8.8.8.8
并且它存在于ifconfig
)。
这是内容/etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
allow-hotplug eth0
iface eth0 inet manual
auto wlan0
allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
auto wlan1
allow-hotplug wlan1
iface wlan1 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
ifconfig
(屏蔽 MAC)的输出

有什么帮助吗?
