This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Ntopng Network Monitoring on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

Install Ntopng on Ubuntu 20.04 LTS Focal Fossa

Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.

sudo apt update
sudo apt upgrade
sudo apt install software-properties-common wget
add-apt-repository universe

Step 2. Installing Ntopng on Ubuntu 20.04.

Before installing Ntopng packages, you need to add the official Ntopng repository to your system:

wget https://packages.ntop.org/apt-stable/20.04/all/apt-ntop-stable.deb

Once the package is downloaded, install it using the following command below:

sudo apt install ./apt-ntop-stable.deb

After that, install the Ntopng and other required packages:

sudo apt install pfring-dkms nprobe ntopng n2disk cento

Step 3. Configure Ntopng.

Now edit the Ntopng configuration file and define your Network Interface, Port, and Location of the PID:

sudo nano /etc/ntopng/ntopng.conf

Change the following lines per your requirements:

-G=/var/run/ntopng.pid
-i=eth0
-w=3000

Save and close the file when you are finished. Next, create a new configuration file and define your Network IP range:

sudo nano /etc/ntopng/ntopng.start

Add the following lines:

--local-networks "0.0.0.0/24" ## gives your local IP Ranges here.
--interface 1

Finally, we must restart the Ntopng service and enable it to start on boot time:

sudo systemctl start ntopng
sudo systemctl enable ntopng

Step 4. Accessing Ntopng Interface.

Once successfully installed, open your web browser and access the Ntopng interface using the URL http://your-server-ip-address:3000. Provide the default username and password as admin/admin and click on the Login button. You should see the following screen:
