Introduction
Ntopng is a free, open-source network monitoring tool with a web interface for real-time network traffic monitoring. Ntopng is the latest version of the original Ntop.
Prerequisites
- A fully-updated Ubuntu Linux 20.04 server.
1. Install Ntopng
You must add the official Ntopng repository to install the latest version of Ntopng. The default Ubuntu repository has older versions.
Add the necessary dependencies.
$ sudo apt install wget gnupg software-properties-common
Download and install the Ntopng repository package.
$ wget https://packages.ntop.org/apt/20.04/all/apt-ntop.deb $ sudo dpkg -i apt-ntop.deb
Update the repository.
$ sudo apt update
Install Ntopng.
$ sudo apt install pfring-dkms nprobe ntopng n2disk cento
2. Configure Ntopng
Find your server's network interfaces.
# ntopng -h
Ntopng shows your available interfaces at the end of the page.
Available interfaces (-i <interface index>): 1. lo 2. enp1s0
Open the Ntopng configuration file.
$ sudo nano /etc/ntopng/ntopng.conf
Add these lines to the end of the file. The
-i=2
parameter instructs Ntopng to use the second interface, enp1s0. Change2
to the interface you want to monitor. Leave3000
as the web server port unless you require a different port.# Network adapter name -i=2 # HTTP port of the embedded web server. -w=3000
Restart the
ntopng
service and set it to run at boot.$ sudo systemctl start ntopng $ sudo systemctl enable ntopng
If you use a firewall like
ufw
, open the web server port.$ sudo ufw allow 3000
3. Test Ntopng
Navigate to your web interface at port 3000. Substitute your server's IP address in this example:
http://192.0.2.123:3000
Log in as username admin
and password admin
.
