pppd

  • linkup時に /lib/netifd/ppp-up が実行される
    • /etc/ppp/ip-up と同じような使い方が可能？
    • Debian ppp-2.4.5/pppd/ipcp.c 
          /*
     * Execute the ip-up script, like this:
     *  /etc/ppp/ip-up interface tty speed local-IP remote-IP
     */
    • 引数の具体例 
      pppoe-wan eth1 0 114.159.68.126 118.23.8.36 wan
  • ONUの再起動(下記)などでpppdが終了してしまった場合、「/etc/init.d/network start」により全てのインタフェースがリセットされ再接続される
