Ntopng is an open source tool used to monitor different network protocols on your servers. It is the next generation version of the original Ntop. Ntopng provides a user friendly web interface to get traffic information and the system network status.
In this tutorial, you will learn how to install Ntopng on Ubuntu 16.04.
Before starting, update the system to the latest stable status using the following commands:
sudo apt-get update -y sudo apt-get upgrade -y sudo shutdown -r now
After the reboot, use the sudo user to log in.
ntopng package is available in the Ubuntu 16.04 repository. You can easily install it by running the following command:
sudo apt-get install ntopng
The configuration file is located at
sudo nano /etc/ntopng.conf
Change the settings in the file as needed:
# DO NOT REMOVE the following option, required for daemonization. -e= # * Interfaces to sniff on: one interface per line, prefix with -i= # If none is specified, ntopng will try to auto-detect the best interface. -i=eth0 # * Port on which ntopng will listen for the web-UI. -w=3000
Save the file when you are finished. Then, restart the
sudo systemctl restart ntopng
To see all available interfaces and options, use the
ntopng -h option:
sudo ntopng -h
If you're running a firewall such as ufw, you'll need to open port 3000 for Ntopng.
sudo ufw allow 3000
It's time to test Ntopng. Open your favorite web browser and type the URL

admin and password
admin to log into Ntopng.
Your Ntopng application is ready for use.
