ifconfig -a

route

两命令的结果。

ifconfig -a
可以看到网卡，因为是服务器，可以看到很多网卡，其中一个eth0有类似10.0.0.5的IP地址，255.255.255.0的boardcast（这个就是网关地址吧），这个结果表明网卡工作正常么？

route
看到的类似
10.0.0.0  255.255.255.0     eth0
169.1x.x.x  255.255.255.0    ifxx
192.168.x.x   255.0.0.0   eth0

对不起，你这么说我不清楚。
要命令结果就是命令结果。不能打折扣的，否则判断不了问题。

ifconfig -a:

你配置了缺省网关了吗。

设了 是10.0.0.255
我也奇怪route似乎没列出这一项

第一，你的windows能否ping过来？
第二，10.0.0.255是什么？怎么能是网关呢？
第三，你有没有插错线啊？

按照你的说法，两台机器是直连的，那么你的网线是交叉线么？

或者你的网卡是否支持自适应呢？

如果你的网卡不是自适应的，并且你使用的是普通网线，那么即使你两台机器的配置都正确，
应该也是ping不通的

iptables-save

或者关闭IPTABLES
