Muy brevemente el problema es el siguiente. Trato de utilizar
HessianPy (RPC ;o).
Cuando trato de efectuar una llamada a un procedimiento remoto desde una PC
(especie de servidor de prueba ;o) con Windows XP, me lanza un error
URLError 11001

Por tanto traté de ejecutar la «suite de pruebas» (hessian.test.test)
desde la línea de comandos y obtengo errores muy parecidos

Habilité logging en el servidor y la llamada (i.e. la petición) no
llega (i.e. HessianPy no está enviando nada). Hasta ahora nbo he
detectado la causa pero estoy 90% convencido que se trata del cliente
de HessianPy
Q:
- Alguien ha tenido errores semejantes anteriormente ?
- Qué es lo que pudiera estar mal ?
- Cómo arreglarlo ?
Cualquier ayuda será muy bienvenida .
Gracias por adelantado.
PS: Aquí les envío el código del cliente de HessianPy [1]_ (más bien
del transporte HTTP ;o) para ver si les ayuda a generar alguna idea
.. [1] hessian.client.HessianProxy
