How To Install Ntopng on Ubuntu 20.04

Before you start to install Ntopng, you need to log in to your server as a non-root user with sudo privileges and set up a basic firewall. To do this, you can follow our article the Initial Server Setup with Ubuntu 20.04.

Set up Ntopng on Ubuntu 20.04

First, you need to update your local package index with the following command:

sudo apt update

$ cd /tmp
$ wget http://apt.ntop.org/20.04/all/apt-ntop.deb

The -w value specifies the port used in the web interface. You can customize it, but remember to open it in the firewall.

Then, restart your Ntopng service on Ubuntu 20.04 to apply the changes:

sudo systemctl restart ntopng
