dht-crawler

Minimal BitTorrent crawler and scheduler with RethinkDB backend to collect, analyse and store peers.

This crawler searches for peers of one or more torrents you define. Its core, forked from Trrnts, searches for peers via the DHT-Protocol and sends ~4000 UDP packages per second. After, the crawler looks up the origin in a GeoIP-database, and stores it after.

The crawler

The DHT protocol implementation

The BitTorrent DHT protocol is based on UDP, which is a connection-less, low-level protocol. The team from Trrnts made a pretty, straight-forward implementation of the protocol, however more abstract ways of DHT-crawling exist.
