Although the Stem script "exit_used.py" runs for a while, eventually it hits "Exception in thread Event Notifier" and stops. Traceback reports that the failing call is:
File "/usr/local/lib/python2.7/dist-packages/stem/control.py", line 2196, in get_circuit
raise exc
ValueError: Tor presently does not have a circuit with the id of 'None'
If I knew Python, I would just trap all "circuit ID = None" errors, and move along. But I don't.
How might I accomplish that?
Background: I'd like to use the Stem script "exit_used.py" to log Tor exits being used while testing load times for various websites (torsocks midori -s https://foo.com). I got the idea from grarpamp's post "Craigslist now giving Tor the slows, lol" in tor-talk.
Edit
I've added a timestamp, and reformatted the output for easy spreadsheet entry.
#!/usr/bin/python
import functools
import time
from stem import StreamStatus
from stem.control import EventType, Controller
def main():
print "Tracking requests for tor exits. Press 'enter' to end."
print
with Controller.from_port() as controller:
controller.authenticate()
stream_listener = functools.partial(stream_event, controller)
controller.add_event_listener(stream_listener, EventType.STREAM)
raw_input() # wait for user to press enter
def stream_event(controller, event):
if event.status == StreamStatus.SUCCEEDED and event.circ_id:
circ = controller.get_circuit(event.circ_id)
exit_fingerprint = circ.path[-1][0]
exit_relay = controller.get_network_status(exit_fingerprint)
t = time.localtime()
print "datetime|%d-%02d-%02d %02d:%02d:%02d % (t.tm_year, t.tm_mon, t.tm_mday, t.tm_hour, t.tm_min, t.tm_sec)
print "website|%s" % (event.target)
print "exitip|%s" % (exit_relay.address)
print "exitport|%i" % (exit_relay.or_port)
print "fingerprint|%s" % exit_relay.fingerprint
print "nickname|%s" % exit_relay.nickname
print "locale|%s" % controller.get_info("ip-to-country/%s" % exit_relay.address, 'unknown')
print
