路由表
路由表
提问于 2012-09-13 13:34:41
我的mac路由表通常很简单。
我知道它是基于bsd的，但是它在做什么或者试图做什么。
我的路由表通常很简单
然而，第二个，默认是指向link5？
这是正常的，还是IPV6在工作中的疯狂？
有人能帮我理解OSX/BSD在做什么吗？

我觉得你找错地方了。在查看原始路由表之前，请检查系统首选项中的“网络首选项”窗格中的基本网络设置。我非常肯定您将看到的是您的en1端口有一个自分配的IP地址为169.254.174.250，并且没有路由器地址。UI并不总是显式地指示它处于自分配模式，但是地址上的169.254前缀是一个死赠品。这意味着DHCP失败了，您的服务器没有被分配到适当的IP地址，因此它组成了一个IP地址(自分配)，而且由于它没有办法组成一个路由器地址，所以它处于链路本地模式，没有路由器，也不知道如何离开本地网络。
路由表看起来如此怪异的原因是，由于它没有配置路由器，所以它试图访问本地网络上的所有内容(也就是说，它为它试图到达的每个IP地址发送ARP请求)。本地网络上的某些内容( MAC地址0:50:7f:5e:92:e2)正在响应这些ARP请求；它可能是一个执行各种ARP代理的路由器。因为OS上的netstat -r将ARP表显示为路由表的一部分，所以您看到的是服务器试图访问的每个IP地址的ARP条目。
第一个解决方案:找出DHCP的问题所在并修复它。
第二个解决方案:服务器在DHCP上做什么？服务器几乎总是静态配置的，所以给它分配一个静态地址(在窗格中，而不是在ifconfig中)。
