How to Install Ntopng on Debian 11 | Debian 10

This is the most efficient and secure way to install Ntopng. Also, you can download it from the APT by adding it to the repository if it is updated.

Then, load a DEB package that adds and configures the Ntopng repository.

cd /tmp

Then start installing GPG to add the tank properly:

sudo apt install gpg

In this step, install the downloaded package to add the tank:

sudo dpkg -i apt-ntop.deb

Now, with the repository already added, we need to refresh the APT packet source:

sudo apt update

Finally, install ntopng and some of its modules with the following command:

sudo apt install pfring-dkms nprobe ntopng n2disk cento

To use the web interface, you need to make some previous configurations. For example, specify the runtime port. To do this, just edit the application configuration file:

sudo nano /etc/ntopng/ntopng.conf



According to the image above, the -w value specifies the port used in the web interface. You can customize it, but remember to open it in the firewall.Also, by creating a new file, you specify the range of your network IP addresses. Also the default or active network interface.

sudo nano /etc/ntopng/ntopng.start/

Then, by restarting the service, the necessary changes are applied:

sudo systemctl restart ntopng

Now, open your web browser and go to HTTP://your-server:[port], you will see the login page.
