How To Install traceroute on CentOS 8
Introduction
In this tutorial we learn how to install traceroute on CentOS 8.
What is traceroute
The traceroute utility displays the route used by IP packets on their way to a specified network (or Internet) host. Traceroute displays the IP number and host name (if possible) of the machines along the route taken by the packets. Traceroute is used as a network debugging tool. If you’re having network connectivity problems, traceroute will show you where the trouble is coming from along the route.
