Olvidenlo era un error tonto...

Estimados.
Tengo un problema al Ejecutar medusa.

El error en particular es el siguiente:

PC# medusa -h localhost -P password.lst -u root -M ssh -n 2222
Medusa v1.1 [http://www.foofus.net] (C) JoMo-Kun / Foofus Networks <jmk@foofus.net>

Viendo en los logs...
efectivamente se lanza el ataque, pero el problema es que se detiene a los pocos segundos...
Alguna sugerencia?
