Do you have any recommendations for a self hosted network analyzer that can visualize all the device connected to a network, different subnets, etc, and perhaps show the flow of data for each network device?
I’m probably asking for too much but sometimes there are cool projects out there that aren’t easy to find.
ntopng has all of that. I’m currently hosting it on my home router.
+1 for this.
You need to see all the data flowing through a sensor to be able to map it, so a router / firewall is often the central point.
I run it as an addon for pfSense and it’ll show me all sorts of info.
If you setup the GeoIP you can see which countries your network’s connecting too… interesting for torrents…
