是否有一个简单的(
linux cli)工具,我可以连续运行一段时间,以查看wan上两个特定网络端点之间是否存在任何连接问题？
一个远程站点正在经历减速/下降,我正在寻找网络哪一侧出错.

接受的答案建议’mtr’;为了将来参考,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.
解决方法
看一下
mtr.它的traceroute和ping合并到一个工具中,并持续监视两个主机之间的路径.你得到如下输出.它可用作Ubuntu的mtr-tiny软件包和CentOS的mtr软件包.
