![]() We’re going to be adding a second USB WiFi dongle to our Raspberry Pi since the BCM43438 WiFi chipset on the Raspberry Pi 3 does not currently support monitoring mode. Optionally Adding a Second Wireless Adaptor However, don’t worry as it’s not anywhere near as hard as SMD soldering and there are several good guides to help you out. These boards use castellated mounting holes, which can be tricky to solder if you’re more used to through hole components. The only soldering needed for the project is attaching the controller boards to the seven-segment displays. It can also be put together with minimal soldering. Most of the hardware for this project is fairly easy to get a hold of and, apart from the giant seven-segment displays and the controller boards for them, you may well have most (or even all) of the bits and pieces you need kicking around your workshop already. So instead, our network scanner is going to be plenty visible. We’re more the glowing red 6-inch tall seven-segment display sort of people. If you did that, you’d end up with a Pi that could sit quietly in a corner and monitor your home or office wireless network, squirreling away information about what hosts are connecting to without anyone taking much notice of it at all. And as we’re going to make use of ARP scans to do it, which are moderately stealthy unless you heavily hammer the network, it would be easy to make something that is pretty much invisible to most people. In short, iNet Network Scanner gives you good guidance into every device on your network.We’re going to make use of a Raspberry Pi to build a network scanner to keep track of the hosts connecting to our local network. You can also scan ports on every device in your network to see if some device has ports open you weren’t expecting it to or doesn’t have ports open you were expecting it to. Want to know how many of the computers on your network are offering some kind of Bonjour print service? Use the app’s Bonjour scanner to see what devices are offering up the Internet Printing Protocol. In addition to scanning for network devices, iNet Network Scanner will scan for Bonjour services being offered on the next work and allows you to view those services by device. This file can also be used to gather inventory information and verify that there are no unauthorized devices on your network. Once iNet Network Scanner has gathered information on all your network devices you can rename those devices and then export a CSV file that can then be imported into Profile Manager. Series on Profile Manager that it was possible to import devices into Profile Manager as placeholders for devices once they’re enrolled in the service. And for those connected devices you can see what the signal and noise level for a selected device, which can give you guidance on the placement of AirPort hardware in your home or office. Regarding AirPorts, if you have any model older than the current 2013 version or an AirPort Express, iNet Network Scanner can provide information about the AirPort, the kind of traffic it’s passing and the number and names of the devices connected to it.
