Ok, now you’ve gotten everything you need to mount a NetFlow probe with Raspberry. Follow the installation procedure as follows

You have to download and install the nfdump packet ( ), it comes compressed in. Previously we’ll download some required tools: Each of these components has a specific function that we’ll take a look at shortly. Next, install the necessary components to enable NetFlow probe: nfdump, a packet which includes fprobe, nfcapd y nfdump. Once Raspberry’s installed and online it’s time to download updated packets and file repositories here: We’re using Raspbian PIXEL, the most recent desktop iteration. Later we’ll look in more detail how to configure your network in order to work with these conditions. Your device’s IP can be automatically designated by DCHP, either by cable or WiFi your router will automatically provide a free IP.

When you boot up Raspberry with the microSD, a wizard will guide you through the installation process, and soon the OS and your device will both be good to go. If you have the card with the NOOBS image you can install the OS directly from there, otherwise download it from the official website and set up your own microSD card. Raspberry comes with a dock for a microSD card, which you can use to install the Raspbian OS. And let’s bring it all in at under €100! Installing and preparing Raspberry Let’s take a look at configuring something similar, with the intention of monitoring NetFlow, using a Raspberry device as a netflow probe, and a Pandora FMS server to store and analyze the NetFlow information. A NetFlow collector this receives the packets generated by one of the above devices (whichever it may be), and stores and processes them usually a dedicated server, or similar network tool.A NetFlow-compatible device usually network hardware such as a router or switch, which generate packets or alternatively, a NetFlow probe.It enables monitoring and analysis of any traffic generated by a specific IP, protocol or software, through allowing filters to be applied based on a source and destination IP address, and a source port and destination port. NetFlow is a web protocol designed and created by Cisco to collect metrics on IP traffic and currently constitutes an industry standard in the world of network monitoring.
