装了Red Hat Enterprise 5.3 但是ping不通网关和其他机器，具体见贴内。

lo ....

peth0 ....

vif0.0....  

virbr0....

已经确认网线和网络设备没有问题。
（用一张能自启动的ubantu linux启动后，配置同样的ip和网关可以Ping通网关和其他机器）

请问会是什么问题？

------解决方案--------------------
试试先将不需要的接口 down...

Perl code

# ifconfig vif0.0 down
# ifconfig virbr0 down

------解决方案--------------------

貌似没有通过 eth0 发送嘛...
