When I nmap the CentOS box, I can’t see that port open. I’ve turned off SELinux, so I’m not sure why I can’t see the open port 5432.
What am I missing? It has to be something I’ve overlooked.
In postgresql.conf change the listen_address to be
listen_address = '*'
by default it only listens on localhost. It's documented in the file and is easily googleable.
Use 'netstat -nlt' (or whatever the modern equivalent is) to see what's listening on which address.
P.
