The Raspberry Pi has its own version of Nagios, the specially configured NagiosPi which is available from this Google Drive share. Scroll down and set the necessary delays (don't make them too short) and click Submit, then in the menu find Generate Nagios Config. The Highly Optimized Radio Scanning Tool (HORST) is a lightweight IEEE802.11 WLAN analyzer. To connect to the network use the same port in advance options setting of the wifi network and then connect 5. But the major advantage is: if you ever want to remove the Raspberry Pi network monitor, just plug the WiFi router directly in to the switch. Raspberry Pi to the rescue. By default this will be something like 192.168.0.x if you use a DHCP router. It turns out one of our other users decided to take the leap into building such capability using a Raspberry Pi. The Raspberry Pi is the perfect tool to get you started, as shown in these DIY projects. Code. The Raspberry Pi is an amazing little inexpensive Linux-based computer. When the image – which is around 1.5 Gb in size – should be extracted following download and written to a spare SD card (over 4 Gb capacity) using ImageWriter (or if you're on Windows, use Win32 Disk Imager; Mac OS X users can employ Pi Filler). It's back..... and it's faster than before. The dnsmasq config file that comes preinstalled contains a lot of functionalities that we don’t require at all so we delete it and create a new one using and paste the contents of dnsmasq.conf into it: Now we need to enable packet forwarding. 4 Reasons Why You Don't Need a Laptop Anymore, How to Batch Rename & Mass Delete Files in Windows, Defeat Planned Obsolescence and Embrace the Right to Repair, 7 Underground Torrent Sites for Getting Uncensored Content. After I have added the LXDE Desktop environment, Firefox, Yay, Pulseaudio, Gimp, Samba and NetworkManager the system increased a lot. Googleing I found a couple of build guides for more inspiration - A complete network analysis tool for the Pi (NetPi) and a spectrum analyzer from Adafruit NetPi - Raspberry Pi Network Analyzer - Blame The Network RF remote sniffer and sender for the Raspberry Pi. All the relevant files can be found on my GitHub repo. Open up the default configuration file with, and find the line #DAEMON_CONF=”“ and replace it with DAEMON_CONF=”/etc/hostapd/hostapd.conf” and this would do the job.

With the image written, pop the SD card into your Raspberry Pi and boot it up. Here, set the Add additional services to host menu to check_ping and click Add. master. Begin by opening your web browser and entering the IP address for your Raspberry Pi in the address bar. It runs on cheap hardware (the raspberry pi platform), and provides a large range of tools for network professionals and those new to the field. The project is open source, released under the GNU GPLv3 license. By drilling down into each you discover more information about the device, and potentially get to the bottom of why it has gone offline. Your Raspberry Pi will need to be connected to your network, preferably by Ethernet cable to start with (you can configure Wi-Fi later) so that you can use it as a headless device via SSH, which is activated by default on NagiosPi. Just plug in the micro USB power supply and this would turn on and boot your Raspberry Pi, Now after the Pi has completed the boot process, a login will appear where you can use the default settings for login into the Pi: Username - pi, Password - raspberry, When you have succeessfully logged in, you will see the command line prompt pi@raspberrypi~$, If you have an ethernet cable plugged in into your Pi, you can start the web browser and see if the internet is working or not, Now type ifconfig in the terminal and note the IP address of your Pi in the eth0 interface(this would be the IP address of the Pi), You now want to create a wifi-hotspot using the wifi-card on the Pi. now we need dhcpcd to run this and we do this by opening: and adding this to the file and saving it: now we are just one step behind sharing our internet through the Pi, just do: and reboot the Pi for rechecking everything worked correctly using: Now you would be able to connect to the internet through the Pi’s network! It got us thinking - what are some other ways you could build a useful network probe? Join our newsletter for tech tips, reviews, free ebooks, and exclusive deals! ZEEK AND YE SHALL FIND. With this tool, it is easy to monitor the state of a server or switch; it's also very easy to find yourself falling down a rabbit warren of options, potentially setting too many checks (which may be counter-productive). I testet already ntop for the raspi (not free). NetPi Plus is a Raspberry Pi 3 B+ project building on an earlier release attempting to build a network analyzer with comparable features to commercial solutions which can range over $1500. Yes, Nagios from source is the best way to monitor your network on Raspberry Pi. A network sniffer (also known as network analyzer or packet analyzer) is a software or hardware that can intercept and log traffic on a network. Here you'll see the device you added is being monitored alongside the others on your network. RaspControl gives you a good idea of what information can be gained from your Pi and other devices, although remote Linux hardware will need the NRPE (Nagios Remote Plugin Executor) installed on them individually so that NagiosPi can communicate with them. Want to know more about online security? Download, Follow the instructions on the software and using a USB Micro SD card reader or an adapter, format the SD card using your laptop or PC. During setup, it’s best to connect your Raspberry Pi running NEMS to your local network using a wired ethernet connection. PiTap: Automated packet capture on a Raspberry Pi #piday #raspberrypi @Raspberry_Pi William Knowles published this great project on his blog . It was built for troubleshooting WLAN networks, and although it’s not as advanced as other tools (Kismet, Wireshark, tcpdump) it’s very easy to use, free, and can run very efficiently even on a Raspberry Pi. But, who would have thought a Raspberry Pi would be powerful enough to act as a real-time 24×7 sniffer?
