He creado un cliente de servicio de eventos CORBA con omniOrb y Python. Tuve el mismo problema con un cliente Java. Estoy muy seguro de que estoy experimentando lo mismo que esta publicación porque mi versión se ve muy similar, pero no explica exactamente cómo la arregló:El 'tnameserv' de Java tarda más de 3 minutos en estar "Listo", ¿por qué?

La conclusión es que mi cliente se inicia pero nunca recibe los eventos del servidor debido al error ETIMEDOUT en ambos lados. Cualquier orientación es muy apreciada!

¡Gracias por adelantado!

EDITAR

Desafortunadamente, actualizar ip6tables (ni iptables) no funcionó.

Parece que puedo tener datos de devolución de una llamada remota, pero tan pronto como TI quiere iniciar la respuesta (evento), causa este problema (vea el comienzo del registro a continuación)

Aquí está mi registro de strace ...
