kdht

kdht is an erlang DHT implementation. You can use this library to join a DHT network, and search torrent info-hash in the network.

Usage

• Download this library source code

• Compile it by erl in the library root directory:

    erl -make
  

• Start erl and specify the module beam path:

    erl -pa ebin
  

• Run test

    testdht:start().
  

Example

-module(testdht).
-include("vlog.hrl").
-export([start/0, stop/1, handle_event/2]).
-export([tell_more_nodes/1]).

start() ->
    vlog:start_link("kdht.txt", ?TRACE),
    random:seed(now()),
    kdht_sup:start_link("dhtstate.dat", 6882, ?MODULE, dht_id:random()).

stop(Pid) ->
    kdht_sup:stop(Pid).

handle_event(announce_peer, {InfoHash, _IP, _BTPort}) ->
    MagHash = dht_id:tohex(InfoHash),
    {ok, FP} = file:open("magnet-link.txt", [append]),
    io:format(FP, "~s~n", [MagHash]),
    file:close(FP);

handle_event(startup, {MyID}) ->
    spawn_link(?MODULE, tell_more_nodes, [MyID]).

tell_more_nodes(MyID) ->
    [search:get_peers(MyID, dht_id:random()) || _ <- lists:seq(1, 10)],
    ?I("tell more nodes done").
