[问题求助]关于一些特定的IP经常"Net Unreachable"的问题 [复制链接]

操作系统为CentOS，iptabl.e未开启。虚拟主机
运行期.间发现有一下Ip无法达到，ping如下:            杀毒

ping 221..210.231.113外贸
PING 221.210.231.11.3 (221.210.231.113) 56(84.) bytes of data.(广告)
From 221.210.231.113 icmp_se.q=0 .Destination Net Unreachable域名
From 221.210.231.113 icmp_seq=1 .Destination Net Un.reachable电脑
...

每几百个就出现一两个(但偶尔就又可以ping通)，有些IP还会出现“No route to host”的情况，http://upload.bbs.csuboy.com/Mon_1004/126_7065_893987e7a18c182.gif[/img]请教，这个问题应该从哪里入手？             汽车
系统配置？还是网络网关？还.是硬件route？--------------彩票

任何建议，谢谢!

好的。。。 线路本身受潮/被老鼠咬过，交换机的性能/负载，路由器的性能负载。。。以及去2端网卡上看看有没overruns 的包~~~

我已经记录下来所有发现有问题的ip地址，等我分析一下贴上来

谢谢 skylove

物理上的问题是指网卡？路由？对方网络？还是都有可能？
我发现这个问题以后，在我们公司的其他机房（同样的软件环境）测试，对于同样的ip也有同样的问题，但是从我们的办公室网络就没问题， ...


为什么问题只对某些ip出现?

如果可以知道这些ip的分布规律可能就可以找到问题

关于丢包的问题，可以是由传输介质的质量问题，交换机性能，路由器性能 几者 决定的，当然对方/己方网卡也有可能导致该情形的出现。

您可以把有问题的ip取出来，然后看看他们经过的物理/逻辑路线？？

谢谢 skylove

还有，出现这个case是说明软件或硬件肯定有问题？还是说，是正常的网络的确有可能对一些IP出现Net Unreachable现象，属于正常现象？

再次感谢。

丢包了。。。 网络传输过程中的问题，一般而言有可能是物理上的问题
