我使用的某些服务器traceroute距离我们有30多跳。如何traceroute跟踪超过30个跃点？
Answers:
来自man 1 traceroute：
-m max_ttl
Specifies the maximum number of hops (max time-to-live value)
traceroute will probe. The default is 30.
如果某个位置的距离超过30跳，则可能仅意味着TTL超过时，最后一跳不会回复。
除非，这是一个故事：
$ traceroute -m100 216.81.59.173
traceroute to 216.81.59.173 (216.81.59.173), 100 hops max, 52 byte packets
