agujero de seguridad??

[Carlos Alarcon <kfre@telefonica.net>]

pues estaba yo mirando logs del samba y veo un fichero llamativo 
"log.gustavo" (yo no tengo ninguna maquina llamada así) y esto es lo que 
me aparece:


[2003/07/22 02:16:26, 0] smbd/service.c:make_connection(249)
  gustavo (199.35.225.187) couldn't find service c
[2003/07/22 02:31:24, 0] smbd/service.c:make_connection(249)
  gustavo (64.91.29.65) couldn't find service c
[2003/07/22 02:42:17, 0] smbd/service.c:make_connection(249)
  gustavo (61.6.102.221) couldn't find service c


bueno resulta que tengo la maquina detrás de un router que solo mapea 
los puertos 80,22 a la maquina debian y a la windows los del e-mule que 
no me acuerdo ahora.

Como es posible que puedan acceder desde esa ip a mi recursos compartidos.

os ajunto el samba.conf

Además me gustaria saber xq los ficheros que tengo como ejecutables no 
se pueden ver desde una maquina windows (al menos desde la mia 
Windows-ME), y cómo se solucionaría eso si se puede.

Gracias de antemano.
