I'm recently setting up and running a Windows 2008 r2 server with VMware Workstation 8.
I'm running a Centos 6.2 virtual linux box with Postgresql 9.1. Everything seems ok locally and I can connect to the CentOS box via a bridged network connection.
I have followed David Ghedini's walkthrough for setting up Postgresql 9.1. So I am able to start a putty session window, log in as root and start psql shell and issue statements as postgres user. My problem is that I cannot connect using pgAdmin III from my Windows 7 client. I have updated the /var/lib/pgsql/9.1/data/postgresql.conf to enable listen_addresses '*', etc.
Could anyone give me any tips on finding my fault. Have ensured Windows Firewall is disabled on the Windows server, too.
The pgAdmin III client reports;
'Server doesn't listen'
The server doesn't accept connections: the connection library reports
could not connect to server: Connection timed out (0x0000274C/10060) Is the server running on host "192.168.1.26" and accepting TCP/IP connections on port 5432?
This is the pg_hba.conf file entry added:
#TYPE DATABASE USER ADDRESS METHOD
host all all 192.168.1.0/24 trust
And the iptables file entries added:
-A INPUT -p tcp -s 0/0 --sport 1024:65535 -d 192.168.1.26 --dport 5432 -m state --state NEW,ESTABLISHED -j ACCEPT
-A OUTPUT -p tcp -s 192.168.1.26 --sport 5432 -d 0/0 --dport 1024:65535 -m state --state ESTABLISHED -j ACCEPT
You need to adjust pg_hba.conf:

Once you add your own host and corresponding user, restart postgresql server so hopefully you can connect.
Also you might need to enable it's port on the network: http://www.cyberciti.biz/tips/postgres-allow-remote-access-tcp-connection.html
Make sure PostgreSQL Server is allowed through the firewall:
On the server machine, go to
Control Panel > System and Security > Windows Firewall > Allow an app through Windows Firewall
Scroll through Allowed apps and features, make sure 'PostgreSQL Server' is checked.
Probably a firewall issue, check it by
systemctl status firewalld.service
you could simply disable it by:
systemctl stop firewalld.service
systemctl disable firewalld.service
Is the server running on host "192.168.1.26" and accepting TCP/IP connections on port 5432?
Check that the server has that IP address. Check that there are postgres processes running. Use netstat to confirm that the server is listening on port 5432.
i have the same problem. I disabled all my third party antiviruses and firewalls and reinstall PostgreSQL again and its now working fine... :)
