Question: Failing UDP trackers: Failed to receive response from the tracker about bt

[atomashpolskiy]

Hi @Raudius ! Thanks for sharing! Yeah, it does seem like the tracker itself is not responding. Considering that bt.tracker.MultiTracker is involved in the stack, there should be an announce-list property in the torrent file. Bt should try announcing to all trackers in this list. Is this the only tracker-related exception in out.log?

[Raudius]

OK so I just realised that HTTP trackers don't work with this library (as they havent been implemented yet(?)). I was able to get those to work through ttorrent.

But with when starting the client I also get this line of output:

1124 [bt.net.pool.incoming-acceptor] INFO bt.net.PeerConnectionPool - Opening server channel for incoming connections @ /192.168.1.40:6891

Which sugggests that it is listening only for connections locally? Shouldnt that be my public address instead?

Then after that line and after the tracker connection times out I get the error in the first post, and it repeats it after each timeout preceded by the error:

151120 [bt.peer.peer-collector] ERROR bt.peer.PeerRegistry - Error when querying peer source: bt.peer.TrackerPeerSource@2456c2b9

HTTP trackers are supported, but for the sake of keeping the core with minimum number of 3-rd party dependencies it's shipped as a separate module.

Include this in your pom.xml:

<dependency>
    <groupId>com.github.atomashpolskiy</groupId>
    <artifactId>bt-core</artifactId>
    <version>1.0-SNAPSHOT</version>
</dependency>
<dependency>
    <groupId>com.github.atomashpolskiy</groupId>
    <artifactId>bt-http-tracker-client</artifactId>
    <version>1.0-SNAPSHOT</version>
</dependency>

Then create your client in the following way:

BtRuntime runtime = BtRuntime.builder().module(new HttpTrackerModule()).build();

Or

BtRuntime runtime = BtRuntime.builder().module(new HttpTrackerModule()).module(new PeerExchangeModule()).build();

if you also want to make use of peer exchange.

You might also want to look through the brief explanation of basic concepts, it should help build a better picture of the main API:

Nope, it's listening on a local port. Peers will be able to contact you via your external address, which will be communicated to them by the tracker, that you are working with.

If you'd like to listen on a different interface/port, use Config [1]:

Config config = new Config();
config.setAcceptorAddress(/* network address */);
config.setAcceptorPort(/* network port */);
// tweak other parameters

BtRuntime runtime = BtRuntime.builder(config).build();
