- nirvdrum 11y agoI have no idea if the the trackers are doing this or not, but you could use TCP/IP stack fingerprinting. It's a bit costly, so I doubt it's in use. But it could be one way to achieve it. It's certainly not 100% accurate, but my experience with nmap is the detection works surprisingly well: https://nmap.org/book/man-os-detection.html https://nmap.org/book/man-os-detection.html
- djrogers 11y agoThat requires the server to be able to make network requests to the host - not gonna happen for most users busting your site.
- deno 11y agoOnly if you use nmap as-is. Also majority of torrent software uses UPnP IGD to open TCP port (which is then advertised to the tracker). I’m not sure but I think µTorrent on Windows also listens on the Toredo provided IPv6 address.
