traceroute

traceroute is a tool to trace the path of an IP packet as it traverses routers, and it is a great utility for checking the route from a source to a destination. The traceroute command is one of the simplest yet most effective ways to troubleshoot network problems.

NOTE:

• Different platforms offer traceroute as a tool, such as TRACERT on Windows or TRACEROUTE on Linux and Mac.
• Installation steps on both platforms are pretty simple, since we will be talking about Linux (Ubuntu). Below are the steps to get this utility installed.
• If you are on RHEL family, you can get this installed by yum.

$ apt-get update -y 
$ apt get install traceroute -y

Here are some examples of how to use the traceroute command in Linux:

To perform a traceroute with a maximum wait time of 2 seconds per hop:
