在终端中输入
sudo pppoeconf
设置完宽带上网后——
问 题：系统启动的时候网卡都没自动激活，每次都要到 系统－－联网 —－激活eth0...
解决方案：看看/etc/network/interfaces是不是像这样的:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# This is a list of hotpluggable network interfaces.
# They will be activated automatically by the hotplug subsystem.
mapping hotplug
script grep
map eth0
# The primary network interface
iface eth0 inet dhcp
--
把/etc/network/interfaces文件末尾多的一条命令那行去掉，我的是多了这么一行：
pre-up /sbin/ifconfig eth0 up
# line maintained by pppoeconf
删掉之后系统就能自动激活eth0了。
然后再在终端里输入:
sudo ln -s /etc/ppp/pppoe_on_boot /etc/ppp/ppp_on_boot
pppoeconf也能自动拨号了。
