toxcrawler is a Tox DHT network crawler. See it in action at https://toxstats.com/.
The crawler crawls the DHT network with multiple concurrent instances, allowing for a steady stream of up-to-date data on the number of active DHT notes on the network at any given time. When a crawler instance completes its mission, a log file containing all space separated IP addresses that it found is created in the crawler_logs/{currentdate}/ directory, with the name {timestamp}.cwl.
Compile and install the DHT-addon branch of toxcore using the given instructions.
Clone this repo to the same base directory as toxcore, then run the command make in the crawler directory.
