How to list all tor circuits that have ever been established

Question

I can get the current with this stem code.

#!/bin/python
from stem import CircStatus
from stem.control import Controller


with Controller.from_port(port = 9051) as controller:
    controller.authenticate()

    for circ in sorted(controller.get_circuits()):
        if circ.status != CircStatus.BUILT:
            continue
    print("Circuit %s" % (circ.id))

How would you list all tor circuits that have ever been established from the moment that tor has been started?

To make things clear, instead of listing the current circuit only (say number 7) I want to list all c

Answer 1

There's no log for this kind of information - and for a good reason: it can hurt the privacy and anonymity of Tor. You can - technically - poll Tor regulary through Stem and keep the log for yourself, but anyway - it's a bad idea IMHO.

Can you please put some more details about what do you need it for? Maybe this task can be solved in another way?
