是什麽网卡？内核没有支持或者模块未加载？还是无线网卡没驱动？

信天游

网卡：Silicon Intergrated System [SiS] sis900 PCI Fast Ethernet
估计是内核未加载，by the way,我在哪里看内核的配置？

知道了，我在/mnt/lfs/var/log/kern.logz中查找sis900,没找到，
那就是内核没有把网卡驱动编译进内核。
呵呵。

sis900 is a common network device and is supported by linux kernel ages ago.

You should ensure your .config to include such support.

CONFIG_SIS900=m (or y)

It should be located at somewhere in network device support.

I have recomplied the kernel,and this is my .config file digest:
CONFIG_SIS900=y
# CONFIG_EPIC100 is not set
# CONFIG_SUNDANCE is not set
# CONFIG_TLAN is not set
# CONFIG_VIA_RHINE is not set
# CONFIG_NET_POCKET is not set
so this means that my net have configged right.

有eth0，谁说没有呢。？

看我这样解释合理不合理：
系统检测到了网卡，我自己也配置了网络，但是没有把网卡驱动编译进内核，所以网络失败。

这种情况似乎不大可能
我怀疑是你设置的IP地址不对,所以网络不通.
