Which stem python code would you suggest to determine whether tor is operational (bootstrapped at 100%) or not?

  • As a client or as a relay?

You need to query the client bootstrap status. It's done - as it's said in control protocol spec like this:

telnet 9051
Connected to
Escape character is '^]'.
AUTHENTICATE "cleartextpassword"
250 OK
GETINFO status/bootstrap-phase
250-status/bootstrap-phase=NOTICE BOOTSTRAP PROGRESS=100 TAG=done SUMMARY="Done"
250 OK
250 closing connection
Connection closed by foreign host.

You need - if using Stem - a Controller class, and the python code doing exactly this will be:

import stem
import stem.connection
from stem.control import Controller

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

if(response.find('SUMMARY="Done"') > 0):
    print "bootstrapped OK"
    print "Bootstrap not finished: " + response

Have a good day!
