"Psql:could not connect to Server:connection refused" Error while connecting to remote database

Problem:

I am trying to connect to a Postgres database installed in a remote server using the following command: Psql-h- host_ip U- db_username Ddb_name This error is occurs: Psql:could not connect to Server:connection refused are the server running on host "" and accepting TCP/IP connections on Port 5432? Postgres installed version is 9.4. Host operating System:ubuntu 15.04 Client Operating System:centos 7 I already tried the following but the issue remains unresolved: Edited pg_hba.conf file to include Host All 0.0.0.0/0 MD5 Edited ' postgresql.conf ' and changed the listen parameter to Listen_addresses= ' * ' Restarted Postgres service. Disabled Firewall and Iptables on host and client. I checked by running the Psql command locally and it worked. I tried the second solution given in this question. Running nmap gave me the following output: Starting Nmap 6.47 ( http://nmap.org ) at 2015-09-07 18:08 IST Nmap scan report for 10.17.250.250 Host is up (0.0000040s latency). Not shown: 997 closed ports PORT STATE SERVICE 22/tcp open ssh 25/tcp open smtp 80/tcp open http Am I missing something. Hope someone can help.

Firewall is still blocking port 5432. Check your configs for iptables. –dmitry Savinkov Sep 7 ' at 17:03 @Dmitry I disabled iptables by running sudo ufw disable , but I ' m still getting the same Error.–poonam Anthony Sep 8 ' 10:2 5 Can you try a ' netstat-na|grep 5432 ' and see if PostgreSQL binds to all interfaces? –kometen Dec ' at

----------------------------------------------------------------------------

cd /etc/postgresql/9.x/main/

Open file namedpostgresql.conf

sudo vi postgresql.conf

Add this line to the file

listen_addresses = ‘*‘

Then open file namedpg_hba.conf

sudo vi pg_hba.conf

and add this line to the file

host  all  all 0.0.0.0/0 md5

It allows access to all databases for all users with an encrypted password

Restart your server

sudo /etc/init.d/postgresql restart
