Ubuntu10.10網卡配置文件重啟失效

   環境:ubuntu 10.10

  目標:配置網卡啟動時加載iptables規則

  網絡上搜到的各種操作:

  sh -c "iptables-save > /etc/iptables.rules"

  vi /etc/network/interfaces

  ## 目標網卡下增加一條命令

  ## pre-up iptables-restore < /etc/iptables.rules

  但是,經測試發現。重啟後這些配置會丟失,查看這個文件頭會發現。

  # This configuration file is auto-generated.

  # WARNING: Do not edit this file, your changes will be lost.

  # Please create/edit /etc/network/interfaces.head and /etc/network/interfaces.tail instead,

  # their contents will be inserted at the beginning and at the end

  # of this file, respectively.

  #

  # NOTE: it is NOT guaranteed that the contents of /etc/network/interfaces.tail

  # will be at the very end of this file.

  文件寫得很明確,/etc/network/interfaces是自動生成的。如果我們需要自定義配置,那就創建/etc/network/interfaces.head或/etc/network/interfaces.tail。其中/etc/network/interfaces.tail並不推薦。

  以下是一個示例:

  auto venet0:0

  iface venet0:0 inet static

  address 184.22.224.125

  netmask 255.255.255.0

  pre-up iptables-restore < /etc/iptables.rules
