<br>
<br>
nmap desde el cliente, aca parece haber algo raro porque ve otros puertos pero no el 5432<br>
<br>
[usuario@cliente ~]# nmap 192.168.1.43<br>
<br>

------------------------------------<br>
<br>
No entiendo porque no lo ve si el nmap lo muestra abierto<br>
Podra ser porque esta con 0.0.0.0 y no especificamente con 192.168.1.43 ???<br>
<br>
Desde ya muchas gracias<br>
