sudo iftop
  1. nload: nload displays real-time graphs of incoming and outgoing traffic.
  • Installation:
sudo apt update

  1. vnStat: vnStat doesn’t exactly show in real-time, but it logs bandwidth usage over time and can show statistics by hours, days, and months.
  • Installation:
sudo apt update
sudo apt install vnstat
  • Configuration and Usage:
    • To initialize vnStat’s database on an interface (e.g., eth0):
sudo vnstat -u -i eth0

vnstat -i eth0
  1. bmon: bmon is another tool that displays real-time network traffic, offering various views and details about network activity.
  • Installation:
sudo apt update
sudo apt install bmon
