Postgresql – can’t connect to remote postgresql database

postgresqlremote

I'm trying to connect to a remote psql database. Before I added the pg_hba.conf entry with the client's IP address, I was getting an error message :

xdev@xdevbox:~$ psql -U postgres testdb -h 10.1.1.47
psql: FATAL:  no pg_hba.conf entry for host "10.201.50.71", user "postgres", database "testdb", SSL off

I added the client's IP with trust settings. I also changed the listen address in postgres.conf on the server to listen to "*".
Then I restarted the database server using /etc/init.d/postgresql restart command.

Now when I try to connect, I get the following error message: 

psql: could not connect to server: Connection refused
    Is the server running on host "10.1.1.47" and accepting
    TCP/IP connections on port 5432?

in postgresql.conf, the port is set to 5432.
I'm not sure what else to check.

Thanks

You have to configure the following two files

pg_hba.conf

host all all 0.0.0.0/0 md5

postgresql.conf

listen_addresses='*'

You have to check if the port 5432 is open: http://www.yougetsignal.com/tools/open-ports/

If it's not then add a rule to your iptables:

iptables -A INPUT -s 0/0 -p tcp --dport 5432 -j ACCEPT

0/0: If you want anybody to access it. You can change it to a specific IP address or range of IP addresses.
