BitTorrent: la descarga no comienza

Question

Estoy tratando de implementar un rastreador de bittorrent en Laravel . Sin embargo, estoy atascado en este momento ya que la descarga no comenzará. Hay un par que parece estar sembrando y estoy 100% seguro de que es conectable. Pero, cuando ejecuto un segundo cliente en una máquina diferente, la descarga no se iniciará. Está atascado en "Conectando a compañeros" (uTorrent).

Desde el rastreador estoy enviando la siguiente respuesta cuando el cliente hace un anuncio:

d8:intervali1000e12:min intervali300e5:peers18:�ؤ�i�ؑ�XÚJU�6e

En el cliente de descarga tengo los siguientes datos:

No estoy muy seguro de qué me estoy perdiendo aquí.

Answer 1

   $port = $_SERVER[''REMOTE_PORT''];

Creo que el problema es que el rastreador en lugar de registrar el puerto que el par de conexión envía en la cadena de anuncio, el rastreador registra el puerto remoto desde el que se conecta el par.
Es casi seguro que es el puerto incorrecto para usar.

Answer 2

Tal vez es porque estableces constantemente

->header(''Content-Type'', $value);

sin configurar nunca el valor de $value ? ¿Entonces la "Anunciar-Respuesta" está malformada?
