ubuntu7.04下pppoe不能自动拨号问题的解决

PART 1解决failed to write cache的问题

最近发神经把linux给格了，重装，装完中文支持，问题就来了，系统干什么都变得奇慢，并且在APT－GET的时候出现了如下的显示

Updating fontconfig cache…
/usr/share/fonts/X11: failed to write cache
/usr/share/fonts/X11/100dpi: failed to write cache
/usr/share/fonts/X11/75dpi: failed to write cache
/usr/share/fonts/X11/Type1: failed to write cache
/usr/share/fonts/X11/encodings: failed to write cache
。。

如果你的系统在APT的过程中也出现了这种情况，请继续往下看。
我在网上搜到了个脚本，用来解决这个问题，把下面的做成脚本运行或者直接复制到终端中运行，然后就搞定了。

#!/bin/bash

PART 2启动系统后无法自动进行pppoe拨号 解决的问题
一般情况下，在使用sudo pppoeconf中选择自动拨号就应该好用，但偶这回就不好用了。。。
解决方法如下
在终端执行

sudo gedit /etc/network/interfaces

对配置文件进行编辑
然后把下面的文字添加到这个配置文件的结尾。

# 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
