问题仍未解决，等候你的帮助！（为节省时间新来的朋友请从26楼往下看，但请不要无声无息地离开哟
）我上星期安装了最新版ubundu，开始一个星期用得好好的，后来因为闲得无聊，东搞搞西搞搞的（也记得弄了什么），还装了个叫firestarter的防火墙！结果只能在管理员用户上网了，
我决心把它修好，
我试过的方法：
1于是把防火墙卸掉了，现在彻底不能上网了
2 sudo gedit /etc/network/interfaces
修改文件/etc/network/interfaces如下文
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
$ sudo /etc/init.d/networking restart
结果：
vicin@vicin-Compaq-Presario-CQ40-Notebook-PC:~$ sudo /etc/init.d/networking restart
