如何在Mac OSX中获取默认网关 [英] How to get default gateway in Mac OSX

问题描述

我需要在Mac机器上检索默认网关.我知道在Linux中，路由-n将给出输出，我可以从中轻松检索此信息.但是，这在Mac OSX(Snow Leopard)中不起作用.

I need to retrieve the default gateway on a Mac machine. I know that in Linux route -n will give an output from which I can easily retrieve this information. However this is not working in Mac OSX(Snow Leopard).

我也尝试过netstat -nr | grep 'default'，但是我希望获得更干净的输出，例如Linux/Unix中route -n产生的输出. netstat -nr列出所有接口和它们的默认网关.

I also tried netstat -nr | grep 'default', but I was hoping for a cleaner output like that produced by route -n in Linux/Unix. netstat -nr lists all the interfaces and the default gateway for them.

任何向正确方向提出的建议或提示，将不胜感激.

Any kind of suggestion or a hint in the right direction will be appreciated.

推荐答案

您可以尝试:

route -n get default

它与GNU/Linux的route -n(甚至是ip route show)不同，但是对于检查默认路由信息很有用. 另外，您可以检查软件包将到达特定主机的路由.例如

It is not the same as GNU/Linux's route -n (or even ip route show) but is useful for checking the default route information. Also, you can check the route that packages will take to a particular host. E.g.

route -n get www.yahoo.com

输出将类似于:

   route to: 98.137.149.56
destination: default
       mask: 128.0.0.0
    gateway: 5.5.0.1
  interface: tun0
      flags: <UP,GATEWAY,DONE,STATIC,PRCLONING>
 recvpipe  sendpipe  ssthresh  rtt,msec    rttvar  hopcount      mtu     expire
       0         0         0         0         0         0      1500         0

恕我直言netstat -nr是您所需要的.甚至MacOSX的Network Utility应用程序(*)都使用netstat的输出来显示路由信息.

IMHO netstat -nr is what you need. Even MacOSX's Network utility app(*) uses the output of netstat to show routing information.

我希望这会有所帮助:)

I hope this helps :)

(*)您可以使用open /Applications/Utilities/Network\ Utility.app
