• ⁨Comment⁩ on ⁨How to check if Tor Onion Service is alive?⁩ ⁨⁨1⁩ ⁨day⁩ ago⁩:

  This 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
  from stem.descriptor.hidden_service import HiddenServiceDescriptorV3
   
  onions = ['2n3tvihf4n27pqyqdtcqywl33kbjuv2kj3eeq6qvbtud57jwiaextmid.onion', '32qywqnlnqzbry42nmotr47ebts3k6lhiwfob6xniosmepz2tsnsx7ad.onion', '4colmnerbjz3xtsjmqogehtpbt5upjzef57huilibbq3wfgpsylub7yd.onion', '6voaf7iamjpufgwoulypzwwecsm2nu7j5jpgadav2rfqixmpl4d65kid.onion', '6w5iasklrbr2kw53zqrsjktgjapvjebxodoki3gjnmvb4dvcbmz7n3qd.onion', '7drfpncjeom3svqkyjitif26ezb3xvmtgyhgplcvqa7wwbb4qdbsjead.onion', 'ae3w7fkzr3elfwsk6mhittjj7e7whme2tumdrhw3dfumy2hsiwomc3yd.onion', 'chillingguw3yu2rmrkqsog4554egiry6fmy264l5wblyadds3c2lnyd.onion', 'fzdx522fvinbaqgwxdet45wryluchpplrkkzkry33um5tufkjd3wdaqd.onion', 'gku6irp4e65ikfkbrdx576zz6biapv37vv2cmklo2qyrtobugwz5iaad.onion', 'gois4b6fahhrlsieupl56xd6ya226m33abzuv26vgfpuvv44wf6vbdad.onion', 'j4dhkkxfcsvzvh3p5djkmuehhgd6t6l7wmzih6b4ss744hegwkiae7ad.onion', 'jabjabdea2eewo3gzfurscj2sjqgddptwumlxi3wur57rzf5itje2rid.onion', 'jaswtrycaot3jzkr7znje4ebazzvbxtzkyyox67frgvgemwfbzzi6uqd.onion', 'jeirlvruhz22jqduzixi6li4xyoweytqglwjons4mbuif76fgslg5uad.onion', 'jukrlvyhgguiedqswc5lehrag2fjunfktouuhi4wozxhb6heyzvshuyd.onion', 'mrbenqxl345o4u7yaln25ayzz5ut6ab3kteulzqusinjdx6oh7obdlad.onion', 'nixnet54icmeh25qsmcsereuoareofzevjqjnw3kki6oxxey3jonwwyd.onion', 'qawb5xl3mxiixobjsw2d45dffngyyacp4yd3wjpmhdrazwvt4ytxvayd.onion', 'qwikoouqore6hxczat3gwbe2ixjpllh3yuhaecixyenprbn6r54mglqd.onion', 'qwikxxeiw4kgmml6vjw2bsxtviuwjce735dunai2djhu6q7qbacq73id.onion', 'razpihro3mgydaiykvxwa44l57opvktqeqfrsg3vvwtmvr2srbkcihyd.onion', 'rurcblzhmdk22kttfkel2zduhyu3r6to7knyc7wiorzrx5gw4c3lftad.onion', 'szd7r26dbcrrrn4jthercrdypxfdmzzrysusyjohn4mpv2zbwcgmeqqd.onion', 'xdkriz6cn2avvcr2vks5lvvtmfojz2ohjzj4fhyuka55mvljeso2ztqd.onion', 'xiynxwxxpw7olq76uhrbvx2ts3i7jagqnqix7arfbknmleuoiwsmt5yd.onion', 'xmppccwrohw3lmfap6e3quep2yzx3thewkfhw4vptb5gwgnkttlq2vyd.onion', 'ynnuxkbbiy5gicdydekpihmpbqd4frruax2mqhpc35xqjxp5ayvrjuqd.onion', 'yxkc2uu3rlwzzhxf2thtnzd7obsdd76vtv7n34zwald76g5ogbvjbbqd.onion']
   
  controller = Controller.from_port(port=9051)
  controller.authenticate()
  if controller.is_alive():
    print( "INFO: Confirmed that Tor is working." )
   
  print( "INFO: Trying get_hidden_service_descriptor()" )
  for onion in onions:
  	print( onion )
  	try:
  		desc = controller.get_hidden_service_descriptor(onion)
  		print( "\tOK" )
  	except Exception as e:
  		print( "\tNo Descriptor Found" )
  

  Example

  And an example execution of the above script follows
