設定

鍵盤設定 keyboard layout

  • 將鍵盤設定為 us layout 配置,否則「|」、「#」、「"」會打不出來。
    sudo vim.tiny /etc/default/keyboard
    更改
    XKBLAYOUT="us"
    

無線網路設定

  • WPA 密碼設定:
    • 設定檔:/etc/network/interfaces
      # allow-hotplug wlan0
      iface wlan0 inet manual
      wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
      iface default inet static
          address 10.1.2.20
          netmask 255.255.255.0
          network 10.1.2.0
          gateway 10.1.2.1
      
  • 使用 DHCP 設定 IP:
    # allow-hotplug wlan0
    iface wlan0 inet manual
    wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
    iface default inet dhcp
    
  • 手動設定 IP 設定檔:/etc/wpa_supplicant/wpa_supplicant.conf
    ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
    update_config=1
    
    network={
        ssid="Your SSID Here"
        proto=RSN
        key_mgmt=WPA-PSK
        pairwise=CCMP TKIP
        group=CCMP TKIP
        psk="YourPresharedKeyHere"
    }
    
  • 重新啟動無線網路。
    # sudo ifdown wlan0
    # sudo ifup wlan0
    ioctl[SIOCSIWAP]: Operation not permitted
    ioctl[SIOCSIWENCODEEXT]: Invalid argument
