Linux ip 隧道 用了几天 ping 就变高了，但是直接 ping 没事，是主机商干的吗

[syjsq]

PING 10.10.1.2 (10.10.1.2) 56(84) bytes of data.
64 bytes from 10.10.1.2: icmp_seq=1 ttl=64 time=78.7 ms

64 bytes from 10.10.1.2: icmp_seq=3 ttl=64 time=78.5 ms



PING 103.52.153.169 (103.52.153.169) 56(84) bytes of data.

就 tm 离谱啊

TCP/UDP 路由是不是变了

[fvladlpa]

很多主机商会优化 ICMP 的路由，看起来 ping 好看，不代表 TCP/UDP 走相同的路由，遇到这种商家还是绕路，选大厂把。

[v2tudnew]

@fvladlpa 这不叫优化，这叫骗

[trepwq]

qos 而已，非 tcp 的 qos 等级都很低

我倒是不会看 tcp 路由，但是用 tcping 测了一下，主机商是真的狗啊，买的前两天正常，等不能退款了就给你改了。

我能爆出来这主机商吗！！

[julyclyde]

爆吧

@syjsq
mtr --tcp

[my2492]

移动也会优化 icmp，但也没这么夸张的差距，这估计是商家小动作

学习了各位，感谢

[ChristianSwift]

@v2tudnew 偷袭？

[v2tudnew]

@ChristianSwift 啥？

@v2tudnew 65 岁老同志

@syjsq 你们是不是号被盗了？
