Question

我有多个服务器具有相同的配置。我试图从每个服务器ping localhost 127.0.0.1。我得到了一个服务器的不同响应。我主要关注除了一个服务器之外的所有服务器的结果。

--- 127.0.0.1 ping statistics ---
19 packets transmitted, 19 received, 0% packet loss, time 18000ms
rtt min/avg/max/mdev = 0.003/0.004/0.011/0.002 ms

问题是，从服务器之一我得到以下结果。

我的/ etc / hosts文件有以下行 127.0.0.1 localhost.localdomain localhost

你能告诉我这里有什么问题吗？

[更新自纪念：]

我担心每包的平均时间，在第二种情况下太高了。

Answer 1

没有错。在这两种情况下，所有数据包仍然可以通过（“0％丢包”）。你只是在第二种情况下获得更详细的输出，每个数据包只有一行（除非你在第一种情况下也得到了它，你只是省略了它。）你的设置或操作只是略有不同系统版本。
