Wifi
使用 NetworkManager 在連接到乙太網時禁用 Wifi
當我通過乙太網(有線)連接到網路時,如何禁用我的 Wifi 無線電,但如果我沒有有線連接,則啟用 Wifi 連接?本質上,我想要我的有線/無線連接狀態的 XOR 開關。
我找到了一個由 Ilija Matoski 編寫的腳本來完成這個任務,它屬於
/etc/NetworkManager/dispatcher.d/70-wifi-wired-exclusive.sh
.#!/bin/sh name_tag="wifi-wired-exclusive" syslog_tag="$name_tag" skip_filename="/etc/NetworkManager/.$name_tag" if [ -f "$skip_filename" ]; then exit 0 fi interface="$1" iface_mode="$2" iface_type=$(nmcli dev | grep "$interface" | tr -s ' ' | cut -d' ' -f2) iface_state=$(nmcli dev | grep "$interface" | tr -s ' ' | cut -d' ' -f3) logger -i -t "$syslog_tag" "Interface: $interface = $iface_state ($iface_type) is $iface_mode" enable_wifi() { logger -i -t "$syslog_tag" "Interface $interface ($iface_type) is down, enabling wifi ..." nmcli radio wifi on } disable_wifi() { logger -i -t "$syslog_tag" "Disabling wifi, ethernet connection detected." nmcli radio wifi off } if [ "$iface_type" = "ethernet" ] && [ "$iface_mode" = "down" ]; then enable_wifi elif [ "$iface_type" = "ethernet" ] && [ "$iface_mode" = "up" ] && [ "$iface_state" = "connected" ]; then disable_wifi fi
此外,要禁用此切換操作,您可以創建文件
/etc/NetworkManager/.wifi-wired-exclusive
(例如 viatouch
)。
