How To Install mtr on CentOS 8
Introduction
In this tutorial we learn how to install mtr on CentOS 8.
What is mtr
MTR combines the functionality of the ’traceroute’ and ‘ping’ programs in a single network diagnostic tool. When MTR is started, it investigates the network connection between the host MTR runs on and the user-specified destination host. Afterwards it determines the address of each network hop between the machines and sends a sequence of ICMP echo requests to each one to determine the quality of the link to each machine. While doing this, it prints running statistics about each machine. MTR provides two user interfaces command line, e.g. for SSH sessions; and a GTK+ interface for X (provided in the mtr-gtk package).
