网卡问题？？？求助

hfcmit

安装完testing后，本人网卡设置如下
# 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

# The primary network interface
auto eth0
iface eth0 inet static
        address 192.168.0.13
        netmask 255.255.255.0
        network 192.168.0.0
        broadcast 192.168.0.255
        gateway 192.168.0.13
        # dns-* options are implemented by the resolvconf package, if installed
        dns-nameservers 192.168.0.13
        dns-search Debian
用pppoeconf配adsl后

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
        address 192.168.0.13
        netmask 255.255.255.0
        network 192.168.0.0
        broadcast 192.168.0.255
        gateway 192.168.0.13
        # dns-* options are implemented by the resolvconf package, if installed

iface dsl-provider inet ppp
provider dsl-provider

auto eth0

    iface eth0 inet manual

重启网卡/etc/init.d/networking restart，出现如下错误
* /etc/network/options is deprecated.
Reconfiguring network interfaces.../etc/network/interfaces:23: interface eth0 declared allow-auto twice
ifdown: couldn't read interfaces file "/etc/network/interfaces"
/etc/network/interfaces:23: interface eth0 declared allow-auto twice
ifup: couldn't read interfaces file "/etc/network/interfaces"
failed.
删除最后两行，错误信息不会在出现，但pon dsl-provider后无反映，无法上网，请问是什么问题？

eth0网卡重复申明。
