问题：掉电后net.eth0出错。

inness2006

睡觉前打开了aMule和Azureus下载东东，醒来的时候发现桌面上所有的窗口都不见了（估计是系统自动重启了，GDM默认设置是自动登录FVWM的）。当时没在意，以为只是普通的软件crash。
再检查才发现网络不通，重启DSL Modem/Router也无济于事。lsmod检查网卡驱动模块也在，ifconfig没有任何信息输出就结束了。

用root运行/etc/init.d/net.eth0得到以下错误信息：

1. 
   
2. localhost init.d # ./net.eth0 restart
   
3. * Starting service net.eth0

重新编译了内核，用knoppix启动系统fsck了root分区，到gentoo英文forum里搜索了老半天，还是没有解决问题：（
我只能猜测系统掉电后丢失了某个重要的文件，可惜distfiles目录早就删空，没法重新emerge dhcp/dhcpcd之类的东东：（

请问哪位知道这到底是怎么了。

尝试重新编译net-tools，如果硬盘上没有的话，需要从liveCD和别的linux里chroot进去来emerge。编译完成后用qpkg -l net-tools 查看安装的文件是否完整。

我去下载了dhcp，dhcpcd，还有net－tools，重新编译了一遍，可惜状况依旧。唉。再试试别的办法吧。。。。

不会如此脆弱吧。硬件的可能性排除了吗？

我也出这个错了，怎么办呢？

我也碰上类似的问题，但要奇怪些
但我的情况是：
1、本机ping自己不通却可以ping通外网，网内其它机器可以ping通这台机器，由此本机访问apache服务不行，网内其他机器可以正常访问，本机也可以正常访问外网。
2、gnome启动后(还没出现启动界面)就没有了响应。

搞了半天都没找到原因所在，真是晕死人了！

就是这样的，我用的是fvwm其他都正常，起的嗯nautilus之类的就没戏了。一下子死掉了／。

我的问题已解决，详见：

原来是sys-apps/baselayout的问题
emerge一下，然后etc-update
/etc/init.d/net.lo start就可以了
