Skyeye1.2.8运行Linux2.6.14正常，但是ping不通主机
Skyeye1.2.8运行Linux2.6.14正常，但是ping不通主机，CS8900网卡安装也正常，Ifconfig 显示都很正常，在Skyeye环境中，eth0的IP地址为：10.0.0.2，在宿主机的一端，eth0的IP地址为：10.0.0.9,出现的TAP0,IP地址为：10.0.0.1，一切似乎都很正常，skyeye也能ping通自己：10.0.0.2，但就是ping不通10.0.0.1，请各位分析一下原因，谢谢:oops:以下是Skyeye的配置文件

可以ping通自己，为什么就是不能Ping通主机，主机也不能ping通skyeye？请各位给分析一下原因，先行谢过！在skyeye端ping 10.0.0.1时，宿主机有反应，详情如下：

宿主机似乎收到了来自skyeye的ping的数据包
同时也回复了skyeye的数据包，不知为什么skyeye不能收到？晕倒，多执行几次ifconfig eth0 down up就可以，实在不能想通
:twisted:总结一下，skyeye运行起来后，
最好把宿主机的网卡重新down和up一下，这样，就肯定可以ping通双方了呵呵
:-D :-D :-D 自问自答呀，呵呵 :roll:传说中的 RPWT ？ 原帖由 jiangtao9999 于 2009-8-31 16:42 发表 http://www.linuxfans.org/bbs/images/common/back.gif
:roll:
传说中的 RPWT ？
可见细节非常关键！
RPWT?是什么意思？:roll: 恩，应该cs8900网卡模拟可能还有一些小的bug。
