Now the file has been opened, you have to add the same configurations, as shown in the screenshot image below. For that purpose, we need to open its configuration file that has been located at /etc/ntopng folder, via the GNU Nano editor. Now the Ntopng has been successfully installed on our system, it’s time to configure it properly. The last lines for the installation completion process would be as given in the image below. You have to wait and sit back while it completes its installation. If you want to install it, you have to hit “Y”, otherwise, press “n”. Meanwhile, within the installation process, the system will pause the installation and ask you to authorize the installation. $ sudo dpkg -i bĪs an alternative to downloading the latest version as shown above, you can install an older release with apt like this: $ sudo apt-get install ntopng Hit the “Enter” key from your keyboard to run this instruction. Now, we can install the downloaded “deb” file using the below command. You can see the package will be downloaded quickly and saved into the system. Hence, use the below query in the shell to do so. Now use the “wget” package to download the “ntop” file package on the system. Hence, install them first, using the below apt-get query. The Ntopng has some dependencies on different packages to be installed on our system. Upon requirement, add your password for the sudo account to continue. For that, execute the stated command in the shell. Now the terminal is opened, we must first update our system and apt packages. If you want to install the software on a server, you can connect e.g. To get started, you need to launch the console application named “terminal” from your system via the Activity area or using “Ctrl+Alt+T” for quick launch to install Ntopng locally. In this guide, I will show you how to install and configure the Ntopng community edition on Ubuntu 20.04. Ntopng comes in professional and corporate editions with license restrictions, as well as a free open source community version. It works with a variety of computer systems, including Windows, Linux, Mac OS, and BSD. It’s an improved kind of innovative Ntop that displays network use, statistics, and analytical data. Any help you can offer would be appreciated.Ntopng is a web-based application for true network traffic flow monitoring that is available as open freeware. Does your setup exhibit this behaviour or is there something wrong with my configuration? Are you able to suggest any settings I can change to correct this? I’ve spent a full day trying without success. It appears traffic is been incorrectly reported twice. Upon further inspection NTOPNG reports 80mbs is to my desktop carrying out the speedtest and another 80mbs by the Raspberry PI running NTOPNG. However with my NTOPNG Pi setup when carrying out a speed test NTOPNG reports around 160mb/s total bandwidth i.e. For example I have an 80Mb/s bandwidth service that figures confirm. Once working I have noticed though that NTOPNG reports roughly twice the actual bandwidth traffic on my home network. I did have to disable DHCP on my router as well as set a static IP address on the Pi too. I’ve purchased a Pi 3B+ and followed your guide and managed to get NTOPNG working. I have only really just scratched the surface of using it. You should now be able view your netowrk traffic via: Ntopng really gives you loads of info. _forward = 1Īdd an appropriate rule to your IP tables script and restart IP tables. This will be temporary so edit /etc/nf and add or un-comment the line below to make the change permanent. Assuming your pi’s address is 192.168.0.2 edit /etc/f as follows # Remote DNS serverĮnable routing/IP forwarding : sysctl -w _forward=1 Installing dnsmasq: sudo apt-get install dnsmasqĬonfigure dnsmasq. Local traffic will not be affected (or monitored) as it is on the same subnet and will not route via the PiĪpt-key add ntop.keyRaspbian Stretch (9.x) echo "deb armhf/" > /etc/apt//ntop.listĮcho "deb all/" > /etc/apt//ntop.list If that were the case I would suggest a different SoC board with true GbE rather than the Pi. Bear in mind that if you have superfast broadband ie over 150Mbs this is going to create a bottleneck and slow down your connection to the internet. This works for both wired and wifi clients. The pi then forwards on the traffic to you broadband router. Raspberry Pi 3B+ (Lower specs work but ntopng is quite CPU intensive)Įssential what we are going to do is use dnsmasq to set the default gateway on client devices so that all traffic is routed via the pi. The main difference here is that we are using ntop rather than his script for network analysis and dnsmasq to handle DNS and DHCP. This guide takes some inspiration from Ronem Baram’s solution. As most broadband routers don’t actually give you a lot of information about your network traffic I thought I would try and see what I could do with my Raspberry pi.
