dhtNodes Always 0

[lqh995204185]

It was good before. The code hasn't changed. I can't get it recently。dhtNodes Always 0

Please try new jlibtorrent 1.2.16.0 https://github.com/frostwire/frostwire-jlibtorrent/releases/tag/release%2F1.2.16.0

[qyzhaojinxi]

Hi, I test 1.2.16.0.jar. And it didn't work on all my test devices including android11 and android12. No speed, no peers, no dht contacts.

[gubatron]

I've just confirmed the same, I'll be deleting those android jars and uploading new ones, I believe there was a patch missing in the build.

Once I test and they work for me I'll upload the new binaries and will provide MD5 hashes for you to check you have the new ones.

Thank you

[gubatron]

@qyzhaojinxi please try again, just uploaded new android jars

@gubatron Thank you. I will try the new ones.

[qyzhaojinxi]

@gubatron Hi, thak for your fix. I have tested the new jar files and they worked well on my devices. But they still don't work on the OPPO Reno 4 pro. It's just like the last version and no speed, no peers, no dht contacts.

[igor-rif-shevchenko]

@gubatron @qyzhaojinxi @lqh995204185 I think I have the same issue (1.2.16.0). Some users reported that nothing downloads. I can't reproduce it on my devices. Several users had Samsung Galaxy but I've tried about 10 devices in Samsung Remote Test Lab and coudn't reproduce that issue. I got logs from one of the users and I've noticed that there is no ListenSucceededAlert, ListenFailedAlert, ExternalIpAlert, LsdPeerAlert, PeerConnectAlert, DhtBootstrapAlert alerts.

[igor-rif-shevchenko]

This seems to be related https://github.com/frostwire/frostwire-jlibtorrent/issues/271

[qyzhaojinxi]

@igor-rif-shevchenko Yes, I think it's the same problem. I can reproduce it on my friend's OPPO Reno 4 pro. It didn't get any alerts. I try to change target 30 to 29 and then worked well. So I think it's about netlink socket and ifaddr sockets. Some devices's kernel are different with others.

[qyzhaojinxi]

Hi, is there any solution for this problem ? There was quit a lot of users meeting this problem. The dhtNodes is always 0.

[igor-rif-shevchenko]

I can confirm, still getting reports that nothing downloads...

[ivan1986]

can confrm too new lib, md5 same, sdk 29 not download

[igor-rif-shevchenko]

Hi @gubatron , I see that the ticket mentioned above (https://github.com/popcorn-time-ru/popcorn-android/pull/1) says that it's working fine in libtorrent4j, maybe there is some clue how it was fixed there?

[qyzhaojinxi]

@igor-rif-shevchenko I'm not sure if it's the same problem.

I can reproduce it on my friend's OPPO Reno 4 pro. It didn't get any alerts and any speed. I try to change target 30 to 29 and then worked well. So I think it's about netlink socket and ifaddr sockets. Some devices's kernel are different with others.

And I test liretorrent app with libtorrent4j on the same device. It works well.

[igor-rif-shevchenko]

That's the point, if it works with libtorrent4j then we can see how it is different from frostwire-jlibtorrent.

try adding this to bootstrap your connection to the DHT on your SettingsPack object before creating the SessionParams object

sp.setString(settings_pack.string_types.dht_bootstrap_nodes.swigValue(), "router.silotis.us:6881");
sp.setString(settings_pack.string_types.dht_bootstrap_nodes.swigValue(), "router.bittorrent.com:6881");
sp.setString(settings_pack.string_types.dht_bootstrap_nodes.swigValue(), "dht.transmissionbt.com:6881");

[igor-rif-shevchenko]

@gubatron but those are already added inside SessionManager, am I mising something? I don't use custom settings pack.

    private static String dhtBootstrapNodes() {
        StringBuilder sb = new StringBuilder();

        sb.append("dht.libtorrent.org:25401").append(",");
        sb.append("router.bittorrent.com:6881").append(",");
        sb.append("router.utorrent.com:6881").append(",");
        sb.append("dht.transmissionbt.com:6881").append(",");
        // for DHT IPv6
        sb.append("router.silotis.us:6881");

        return sb.toString();
    }

and @qyzhaojinxi said it works on his device when he changes target 29, that wouldn't work if it was something wrong with settings pack, right?

sp.setString(settings_pack.string_types.dht_bootstrap_nodes.swigValue(), "dht.transmissionbt.com:6881");

If this code is necessary? Which one is correct comparing with the code in dhtBootstrapNodes?

[igor-rif-shevchenko]

@gubatron do you have any idea what's going on? I keep getting feedback that nothing downloads and just can't do anything about it...

[gubatron]

will look at this on the next update, which could be as soon as this week. I'm on the road now, will be back home by Wednesday.

My guess is that the patch we did for ifnet sockets doesn't work with some android kernels that the maintainers decided to not do as it was dictated by the android project, so the patch ends up breaking connectivity as it tries to use the wrong type of socket

[igor-rif-shevchenko]

@gubatron any news? Does new 1.2.17.0 version have some changes related?

[gubatron]

@igor-rif-shevchenko please give it a try and see if it works now

[igor-rif-shevchenko]

@qyzhaojinxi can you test? I don't have a device with that issue

[qyzhaojinxi]

@igor-rif-shevchenko Sorry about that I can't find the device either. But I will use the latest verison sdk and see the difference about user feedback.

[lyxxman]

There are still such problems
