I2P support

[ghost]

libtorrent version: 1.1.1.0 platform/architecture: Ubuntu 17.10

Hey, i am just curious what is the status of the I2P support. The documentation about this feature is a little bit light right now. In particular i am not sure where i do mistake in the following python code:

import libtorrent as lt session = lt.session(flags=0) h = session.add_torrent({'ti': lt.torrent_info('/tmp/Downloads/test.torrent'), 'save_path': '/tmp/Downloads'})

session.listen_on(6881, 6881)

proxy_settings = lt.proxy_settings() proxy_settings.hostname = '127.0.0.1' proxy_settings.port = 7656 session.set_i2p_proxy(proxy_settings)

The program doesnot download anything and cannot find peers(the i2pshark do it very fast). Please help me to figure out what is going on. Am i right that libtorrent use SAM interface, so i should use port 7656?

[arvidn]

Yes, libtorrent use the SAM protocol. The main problem with libtorrent's i2p support is that it does not have any regression tests, so it's possible that it has broken at some point.

Do you have a log of the alerts you get? please enable all alerts in the alert_mask in the settings_pack.

[ghost]

As you suggested i added to the code

session.set_alert_mask(lt.alert.category_t.all_categories) and

in the end time.sleep(4) alerts = session.pop_alerts() for alert in alerts: print(type(alert).name, alert.message())

And get the following:

add_torrent_alert added torrent: test listen_succeeded_alert successfully listening on [TCP] [::]:6861 listen_succeeded_alert successfully listening on [TCP] 0.0.0.0:6861 listen_succeeded_alert successfully listening on [UDP] 0.0.0.0:6861 state_changed_alert : state changed to: downloading torrent_checked_alert checked

Everything looks fine for me.

The torrent is from tracker2.postman.i2p. I read that previously the tracker was not supported by the libtorrent, because the program did not support base32 names. Am i correct that now base32 names are supproted?

[arvidn]

there must be more alerts than that, right? things like announces to the trackers for instance.

[ghost]

Indeed, it is strange. i do not see any other alerts

[arvidn]

oh, you're probably setting the mask after everything already happened. set the mask as part of the settings_pack and pass that into the session constructor

[ghost]

Ok, i put session = lt.session(alert_mask=lt.alert.category_t.all_categories,flags=0) and get that the host not found. The full alert is

after few seconds in the end i get Segmentation fault (core dumped)

[ghost]

The program looks like this:

import libtorrent as lt import time

session = lt.session(alert_mask=lt.alert.category_t.all_categories,flags=0) print('Session started: ', lt.version)

h = session.add_torrent({'ti': lt.torrent_info('/tmp/Downloads/test.torrent'), 'save_path': '/tmp/Downloads/'})

h.auto_managed(False)

session.listen_on(6861, 6861) proxy_settings = lt.proxy_settings() proxy_settings.type=lt.proxy_type.i2p_proxy proxy_settings.hostname = '127.0.0.1' proxy_settings.port = 7656 session.set_i2p_proxy(proxy_settings) s = h.status() s.num_peers time.sleep(4) alerts = session.pop_alerts() for alert in alerts: print(type(alert).name, alert.message())

Without h.auto_managed(False) i get the alerts above but the program crashes.

With h.auto_managed(False) the program doesnot crash and i get only this:

listen_succeeded_alert successfully listening on [TCP] [::]:6881 listen_succeeded_alert successfully listening on [TCP] 0.0.0.0:6881 listen_succeeded_alert successfully listening on [UDP] 0.0.0.0:6881 add_torrent_alert added torrent: test torrent_added_alert added listen_succeeded_alert successfully listening on [TCP] [::]:6861 listen_succeeded_alert successfully listening on [TCP] 0.0.0.0:6861 listen_succeeded_alert successfully listening on [UDP] 0.0.0.0:6861 state_changed_alert : state changed to: downloading torrent_checked_alert checked

[ghost]

I am still trying to find my mistake. I rewrote c++

{
  using namespace libtorrent;
  namespace lt = libtorrent;

  settings_pack sett;
  sett.set_str(settings_pack::listen_interfaces, "0.0.0.0:6881");
  sett.set_int(settings_pack::proxy_type, settings_pack::i2p_proxy);
  sett.set_int(settings_pack::i2p_port, 7656);
  sett.set_str(settings_pack::i2p_hostname, "0.0.0.0");
  sett.set_bool(settings_pack::force_proxy, true);
  sett.set_bool(settings_pack::enable_upnp, false);
  sett.set_bool(settings_pack::enable_natpmp, false);
  sett.set_bool(settings_pack::enable_dht, false);

  lt::session s(sett);
  s.set_alert_mask(lt::alert::all_categories);
  std::vector<libtorrent::alert*> alerts;
  add_torrent_params p;
  p.save_path = "./";
  error_code ec;
  p.ti = boost::make_shared<torrent_info>(std::string(argv[1]), boost::ref(ec), 0);
  if (ec)
  {
    fprintf(stderr, "%s\n", ec.message().c_str());
    return 1;
  }
  s.add_torrent(p, ec);
 if (ec)
  {
    fprintf(stderr, "%s\n", ec.message().c_str());
    return 1;
  }

usleep(60000000);
 s.pop_alerts(&alerts);
 for(libtorrent::alert const *a : alerts) {
            std::cout << a->message();
        printf("\n");
 }

In the result i get

Ok, i build libtorrent with the debug option. It seems it is some kind of bug in the libtorrent. gdb shows the following

[arvidn]

yeah, it seems like there's an issue with the i2p support in the http_connection or http_tracker_connection. The proper fix for this includes implementing a simple mock SAM server in the simulator, to be able to have tests. The reason I haven't done that yet is that I haven't really considered i2p support a critical (or particularly popular) feature.

[arvidn]

this error message: "*** tracker error: (161) Waiting for i2p acceptor from SAM bridge" suggests that the SAM connection isn't being established correctly. That's no excuse to assert or crash obviously, but it might be worth looking at what might be going on with the bridge if you want to get it to work.

specifically, it means the local i2p endpoint has not been looked up yet (which is done by the SAM name lookup of "ME"). It either means we haven't even connected yet, or the name lookup hasn't returned (which presumably means something is wrong)

[arvidn]

does this help any? https://github.com/arvidn/libtorrent/pull/2564

[arvidn]

@reichKV do you think you will have a chance to try that patch?

[ghost]

Sure i will try to do it

[ghost]

Sorry for the delay. I understand that i am probably the only one in the world who uses libtorrent in i2p. I need this for educational purposes. And I appreciate your help.

i used your pathes and with the test program, which i described above, i get the following

1. No crashes.
2. However the program starts and almost immediately stops. The alerts are:

[ghost]

Previously i got the errors with the standard java i2p and c++ i2p. Right now i used c++ i2p. I can do the same with java i2p if you think the problem can be with the router

[gitbugged]

@ReichKV you're certainly not the only one, I just encountered the same bug. This is also a blocker for qBittorrent implementing it. With the death of Net Neutrality and more ISPs throttling/blocking torrents, I think this issue will begin to see more popularity. Hopefully it will get resolved soon so that we can get libtorrent-based torrent clients back on the network.

[gitbugged]

Possibly related:

I2P developers told me that the implementation of SAM control protocol in the official libtorrent is not complete. The b32 announce protocol was not implemented, and only b64 announce protocol was implemented, but it is not supported by postman.i2p tracker.

• Additional Specs

[proninyaroslav]

Is I2P ready for real use? I'm interested in the implementation of this functionality in my app, but as far as I understand this feature is still buggy.

[arvidn]

there's a bit of a chicken and egg-problem. i2p has definitely worked. Last time I looked at it I made some fixes and got it to work. The problem is that there are no unit tests to ensure that it keeps working, and nobody really seems to care (enough at least).

If you would want this to get into a reliable shape (for all I know it is in a good shape, just not reliable because there are no regression tests), please test it out and report errors. Or better yet, write some tests to demonstrate problems!

[ghost]

I would love to see libtorrent get fuller support for i2p, if possible. And, further, it would be nice if some standard could be drawn up to help humans know whether torrents are bridged between i2p and clearnet. For example, trackers might support a flag to indicate whether they have peers on either network, and a DHT node might return a flag to show they're bridging i2p and clearnet also. That might allow clearnet torrent trackers to start marking torrents as being "darknet enabled", helping to encourage more secure and private torrenting.

[master255]

@arvidn If there is no i2p proxy support, why is it in the instructions and can be selected in the library? And even in Wikipedia? Or if there is support for i2p, where are the instructions, how to configure that it would work?

[absolutep]

Is there any update on this?

[master255]

@absolutep The main problem with i2p is the low data transfer rate. Have they fixed that problem there yet?

[master255]

And don't use gestures. If you have something to say, do it like civilized people - with words.

[TomasGlgg]

@absolutep The main problem with i2p is the low data transfer rate. Have they fixed that problem there yet?

Using I2Pd + BiglyBT, you can get a speed of almost 2 MB/s. I think this is an acceptable speed.

[master255]

@TomasGlgg No. I don't think so. An acceptable speed is at least 100 Megabits. If it can be achieved, then torrents in i2p make sense.

[proninyaroslav]

@master255 In many countries of the world, this is an unattainable value, especially if you use mobile Internet.

[ivan1986]

@master255 it's better that nothing, torrent client works on backgroud, if need download film need just wait some hours, some torrents may download week - speed not a issue.

[master255]

@proninyaroslav Of course the speed of the Internet should be 100 Megabits +. This goes without saying.

[master255]

@ivan1986 There is an alternative to i2p which is https url seeds. There is no speed limit and traffic is reliably encrypted.

[TomasGlgg]

@ivan1986 There is an alternative to i2p which is https url seeds. There is no speed limit and traffic is reliably encrypted.

Https url seeds is not an alternative to I2P. I2P is used for anonymity. You can read about how I2P works on http://geti2p.net/en/

[ivan1986]

@master255 it's not alternative, it's one more support protocol i2p is perfect to hide users from lawers - it's a main issue of torrent protocol now - lawyers do not distinguish ubuntu torrent from a movie it's a most popular torrent library - if it will support i2p i2p net is grow very well

[master255]

@TomasGlgg I know how i2p works. But how can anyone trace that you download a file if you download a torrent file over https protocol and then the file itself over https protocol? And url seeds can be obtained by a normal request in DHT or tracker.

[TomasGlgg]

I know how i2p works. But how can anyone trace that you download a file if you download a torrent file over https protocol and then the file itself over https protocol? And url seeds can be obtained by a normal request in DHT or tracker.

As far as I understand, the download comes directly from seeds and everyone will know your IP address.

[master255]

@TomasGlgg But we can also know the ip address of those who spy on you. And block them. For example using country blocking.

[ivan1986]

@master255 now lawers may connect to dht network and get ip adresses of users - url seeds not help to hide ip adress of user - in the current situation, an anonymous protocol is needed that would not reveal the participants in the exchange, since we have malicious participants - existing solutions at the moment are i2p or tor. We need a protocol with which you can safely distribute and download torrents in countries with very inadequate legislation in this matter - the usa, england, germany. Block ip will not help, this can be you ISP

[TomasGlgg]

But we can also know the ip address of those who spy on you. And block them. For example using country blocking.

This is no longer anonymity :D. How do we know who's spying on us?

[master255]

@TomasGlgg To give you an example. You live in England. Block England and they won't know what you're downloading in England because you won't be downloading from England peers. And your ip will not be recorded anywhere, because downloading from Web seeds is not related to torrent protocol and all methods of distribution of peers. You get complete anonymity.

[TomasGlgg]

@master255 It won't help. Read the post by @ivan1986.

[master255]

@ivan1986 There are no fines for requesting and receiving data in DHT. Fines come for downloading data. If fines came for requests, you could make 10,000 requests per second and get billions of fines. That, of course, is not the case. Blocking ip addresses includes blocking the internet provider as well.

There are no fines for requesting and receiving data in DHT.

We are not talking about fines now, but about anonymity.

Blocking ip addresses includes blocking the internet provider as well.

How do you block an ISP if it works from any IP address?

Anonymity for what?

How do you block an ISP if it works from any IP address?

How could it be? White ip addresses are tied to the country. No one can have an ip address from another country. And how will the ISP even know you're using torrents? To him it will look like you are downloading 2 encrypted files via https protocol.

I can get an IP from another country pretty easily, actually... Quite a few, in fact

[master255]

@cathalgarvey 1. How?

2. And can you have many ip addresses at once?
3. And how do you know which countries I will block?

You can ask this question to the developers of I2P and its community, but not here.

How could it be?

This is not the place to explain how internet work.

There are no fines for requesting and receiving data in DHT. Fines come for downloading data.

And what for we need dht requests without the download data? We still show our ip to other peer, which may seed torrent for log ip's of peers and use it for send fines.

It may be from another country, blocking any range will not help, you just need your own address that cannot be associated with you personally and your location.

This is how it usually happens now - copyright holders download the file, record all IP addresses in the swarm and then send notifications to providers. From this protection option is only vpn at the moment.

At the moment, torrent users use mostly paid vpn to avoid this, we are asked to support a free anonymous network.

Also, ISP can easily just offer a webseed for any torrent in the world. Just 404 when someone connects to the URL (no need to have the file), after logging their IP and correlating with the peer you gave the webseed to. Pretty simple attack, I reckon.

I2P isn't complex and slow because its developers are too dumb to use HTTPS. It's complex and slow because that's a requirement for meaningful anonymity and security.

It would be cool if libtorrent supported torrents through i2p because it would make it easier and safer for people to seed rare torrents that could act as reliable reseeds for clearnet torrenters.

This isn't about being as fast as clearnet - it's about keeping valuable torrents alive, safely. Think investigative journalism archives or insurance files or large leaks from somewhere like Saudi, or Russia. Webseeds are not the answer to keeping this stuff safely online. i2p torrents could be.

@oleg - VPNs, or VPSes running daemonised torrent clients. This is not complicated, it's pretty routine, esoecially for bittorrent. Serious bittorrent users rarely use their own IP address - they use a VPN for their own machine, or they rent or set up a seedbox (a VPS with bittorrent on it).

IP addresses are not rare, or magic, or hard to get. You can trivially avoid geoblocks if you're an attacker.
