我想弄清楚为什么我无法从Mac OSX Yosemite到达特定网站。服务提供商建议我运行一个traceroute
,当我这样做时,无论目的地如何,我都会得到这样的结果:

请注意步骤6中的三个星号(*
),当这些是打印时,它非常慢,每个星号需要大约四秒钟才会出现。根据手册页:
如果在5秒内没有响应。超时间隔(使用-w标志更改),为该探测器打印“*”。
为什么在第6行没有探测器的名称,或者只是第7行?我注意到另一个康卡斯特服务提供位置的类似结果。我应该和Comcast谈谈,如果是的话,我会要求他们解决什么?此问题是否表明访问特定网站无法正常工作?除了定期问题到达顶部提到的网站之外,我还定期遇到VNC
与完全不相关的系统的会话,该系统具有3到4秒的超时,其中屏幕没有被刷新。运行a traceroute
,我发现了该目的地的类似问题。几个月来我一直在看这些问题,但traceroute
一直在给出超时。
