Ntopng (ntop) – web-based network traffic monitoring system – Linux – Debian.

Ntopng is the next generation version of the original ntop, a network traffic probe that shows the network usage, similar to what the popular top Unix command does. ntopng is based on libpcap and it has been written in a portable way in order to virtually run on every Unix platform, MacOSX and on Win32 as well.


1. Install some needed dependencies.

sudo apt-get install autoconf automake autogen libsqlite3-dev libhiredis-dev libtool rrdtool libpcap-dev libglib2.0 libglib2.0-dev libgeoip-dev redis-server wget libxml2-dev build-essential libcurl-dev libmysqlclient-dev checkinstall

2. Download and install ntopng.

sudo mkdir -p install
cd install
sudo wget --trust-server-names http://sourceforge.net/projects/ntop/files/ntopng/ntopng-1.2.1.tgz/download


3. Compiling ntopng from Source Code (with geoip database).

sudo tar -xf ntopng-1.2.1.tgz
cd ntopng-1.2.1
sudo ./autogen.sh
sudo ./configure
sudo make geoip
sudo make

After this command  the installation and creating new package ntopng_1.2.1-1_amd64.deb will begin.

sudo checkinstall

 Done. The new package has been installed and saved to


 You can remove it from your system anytime using:

      dpkg -r ntopng


The new package should be located in install folder e.g:



To remove ntopng use command below:

sudo dpkg -r ntopng


4. Configure init script ntopng.


Create ntopng configfile in /etc/default folder and create new folder for logs:

sudo mkdir /var/log/ntopng
sudo touch /var/log/ntopng/startup.log
sudo wget http://terminal28.com/wp-content/uploads/2014/08/ntopng-init-script-deb.tar.gz
sudo tar xvzf ntopng-init-script-deb.tar.gz -C /
sudo chmod +x /etc/default/ntopng 
sudo chmod +x /etc/init.d/ntopng


Configure  ntopng /etc/default/ntopng:

sudo nano /etc/default/ntopng



Configure network interfaces e.g:.

INTERFACES="eth0 eth1 wlan0"

Port on which ntopng will listen for the web-UI – default port 3000.


Additional command-line arguments for ntopng, more: ntopng –help.


5. First run.

sudo /etc/init.d/redis-server restart
sudo /etc/init.d/ntopng start


6. Accesss to Ntopng:


Username/password: admin/admin.


7. Configure Apache2 server as a proxy with SSL.

Install Apache2 server using this tutorial:


Edit configfile e.g: httpd.conf:

Create 2 virtualhosts:

Configure virtualhost to listen on port 80 and redirect to port 443 (SSL).

sudo nano /etc/appache2/httpd.conf


<VirtualHost *:80>
ServerName ntopng.domain.com
ServerAlias *.ntopng.domain.com
ErrorLog /var/log/apache2/error.log
CustomLog /var/log/apache2/access.log combined
RewriteCond %{SERVER_PORT} !^443$
RedirectMatch ^/$ https://ntopng.domain.com


Configure virtualhost to listen on port 443 and proxy.

<VirtualHost *:443>
ServerName ntopng.domain.com
ServerAlias *.ntopng.domain.com
ErrorLog /var/log/apache2/error.log
CustomLog /var/log/apache2/access.log combined
ProxyPass / http://localhost:3000/
SSLEngine on
SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown
SSLCertificateFile /etc/apache2/ssl/ntopng.domain.com.crt
SSLCertificateKeyFile /etc/apache2/ssl/ntopng.domain.com.key



8. Activate proxy modul and restart Apache2 server.

sudo a2enmod proxy
sudo a2enmod proxy_http
sudo /etc/init.d/apache2 restart


9. Access to ntop through Apache2 server with SSL:


Username/password: admin/admin.
