连PING都会丢包 SSH TELNET连接也会有问题
其他机子没问题 就一台机子有问题的话
考虑下 换个IP 或者 好好检查下问题机器

下面是我在同一个机房下其它可以ssh服务器通过tcpdump host 218.93.210.239，
然后用ssh连接218.93.210.239抓到的包
包中好像有大量的arp who-has 218.93.210.80 tell 218.93.210.239
是什么原因呢？ftpidc112# tcpdump host 218.93.210.239

通过ping该服务器的ip时而Request timed out.时而可以ping通。
通过cmd窗口telnet ip 22 端口，有时可以连接得上，有时连接不了。

你觉得这是什么原因呢？

只是广播而已。

arp who-has 218.93.210.80 tell 218.93.210.239
会不会有arp病毒啊
