有没有一个简单的（linux cli）工具，我可以连续运行一段时间，看看在两个特定的networking端点之间是否有连接问题？
一个远程站点正在经历减速/下降，我正在找出o找出networking的哪一侧出现故障。

接受的答案build议' mtr '; 为了将来的参考， mtr接受以下相关选项：
--report This option puts mtr into report mode. When in this mode, mtr will run for the number of cycles specified by the -c option, and then print statistics and exit. This mode is useful for generating statistics about network quality. Note that each running instance of mtr generates a significant amount of network traffic. Using mtr to measure the quality of your network may result in decreased network performance. --report-cycles COUNT Use this option to set the number of pings sent to determine both the machines on the network and the reliability of those machines. Each cycle lasts one second. 看看mtr 。 它将traceroute和ping合并为一个工具，并不断监视两台主机之间的path。 你得到如下的输出。 它可以作为Ubuntu的mtr-tiny包和CentOS的mtr包。

我会用这样一个小的shell脚本来做到这一点：
#!/bin/bash while true; do date >> mylogfile.txt ping -c 5 sometestnode >> mylogfile.txt sleep 5 done
像这样运行脚本，使其在注销后继续运行：
nohup scriptname.sh &
一旦你等了一段时间，你只需要杀死进程并查看你的日志文件。 当然这可以调整任何你想要的方式。
