5 days agoThis can be done by querying the “Hidden Service Descriptor”.
By default, Onion Services publish a “Hidden Service Descriptor” to the Tor network’s distributed Hidden Service Directory (HDir) every 3 hours.
The Hidden Service Descriptor returned by the HDir contains the metadata necessary for a client to connect to the Onion Service.
If a given Onion Service’s Hidden Service Descriptor cannot be found, then the Onion Service is likely dead.
Script
Here’s a simple python script that queries the HDir for a list of onions
from stem.control import Controller
