How to install iftop on Rocky Linux 9.3

To Install Iftop On Rocky Linux 9.3

Introduction:

iftop is a command line tool that shows a list of active network connections between the local host and any remote host, sorted by their bandwidth usage. The list of top-ranking network connections (in terms of bandwidth usage) is periodically refreshed in a ncurses-based user interface. Using iftop, you can visually check the bidirectional bandwidth usage of different network connections in real-time.

Installation Steps:

Step 1: Check the OS version by using the below Command.

[root@linuxhelp ~]# cat /etc/os-release

Many EPEL packages require the CodeReady Builder (CRB) repository.
It is recommended that you run /usr/bin/crb enable to enable the CRB repository.
