Mtr网络节点诊断工具

一般判断网络连通性用ping 和tracert.
ping的话可以来判断丢包率,tracert可以用来跟踪路由.

在Linux中有一个更好的网络连通性判断工具,它可以结合ping nslookup tracert 来判断网络的相关特性,这个命令就是mtr

官方说明

mtr combines the functionality of the 'traceroute' and 'ping' programs in a single network diagnostic tool.

As mtr starts, it investigates the network connection between the host mtr runs on and a user-specified destination host.  
After it determines the address of each network hop between the machines, 
it sends a sequence of ICMP ECHO requests to each one to determine the quality of the link to each machine.  
As it does this, it prints running statistics about each machine.
