用XP的启动管理来搞定Vista、XP双系统

（1）免输入密码：

每次pppoeconf都需要输密码，可以修改：/etc/ppp/peers/dsl-provider文件，在其中增加密码，就可以省略输入密码了：
password 拨号密码

（2）自动拨号
编辑 /etc/network/interfaces
将 pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf
这一行移到 auto dsl-provider 上面

# added by pppoeconf

auto eth0

iface eth0 inet manual

pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf

auto dsl-provider

iface dsl-provider inet ppp

provider dsl-provider

我的系统有两个无线网卡，一个有线网卡，通过无线网卡与路由器进行连接：
interfaces：

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet manual

pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf

auto dsl-provider
iface dsl-provider inet ppp
#pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf
provider dsl-provider

#auto eth0
#iface eth0 inet manual

auto wlan0
iface wlan0 inet manual

auto wlan1
iface wlan1 inet manual

我的一个拨号脚本：

#!/bin/sh

echo "Please Select:"
echo "\t1\tAuto pppoe config and dial up!"
echo "\t2\tpppoe on"
echo "\t3\tpppoe off"
