万能的CFC：上网困难求助

[mianfei]

近来很多网站无法访问，Traffic都被cogentco的两个核心路由器给贪污了：
te4-1.mag01.sjc03.atlas.cogentco.com [154.54.82.90]
te0-0-0-3.ccr21.sjc03.atlas.cogentco.com [154.54.82.89]
各位有何解决问题的高见？

ISP 是ACANAC

 

[mianfei]

有谁可以去San Jose找到这家公司把这两个路由器给关了，给他们发邮件，没人理啊。

 

[mianfei]

劫持我的数据包，吃果果的流氓行为啊。

 

[uglyducking]

Traceroute问题，hops超30个了。

 

[mianfei]

30个HOP都找不到，30以下更不灵了。
事实是Traffic 在两个
te4-1.mag01.sjc03.atlas.cogentco.com [154.54.82.90]
te0-0-0-3.ccr21.sjc03.atlas.cogentco.com [154.54.82.89]
之间来回循环， TTl 11与30没区别，打到最高255也一样，他们的路由有死循环。

不懂。

俗称踢皮球

 

[mianfei]

cogentco是美国的大运营商了，竟然干这事儿！

 

[uglyducking]

I:

'Sometimes you might see a route start �looping� back and forth between two routers, until the 30-hop limit is reached. This is a routing loop. This usually means that one router has lost communication (BGP) with another, and thus has dropped that route. Since the router has lost the route it needs, it sends the packet back where it came from, thinking maybe that is the best route. That router knows better and sends it back to the other one, over and over.'

[mianfei]

Loop detection 是个基本的古老t功能，他们没花钱买吗？

 

[mianfei]

te4-1， te0-0-0-3赫赫，想省钱，玩TE，害死我了，没有文学城，就等同于吃饱喝足才发现没有抽水马桶啊。

 

[whitegret]

太专业了，为了上文学城，isp的loop都被找出来了。这谁能帮你？以后有问题得找你帮忙。

 

[ModemOutlet]

换上网公司

先找个 FREE 的 VPN 暂时用用。
