Обсуждение: Configure foreign host for PostgreSQL 8.0.3 on WindowsXP
Installed PostgreSQL 8.0.3 on WindowsXP. Have not been able to configure so that a client program running on a different WindowsXP box can connect to the PostgreSQL database.
As I understand the documentation, at least one of the following configurations should work, but none do. What have I done wrong and how can I configure so that a connection can be successfully made?
1) The postgresql.conf file has (with everything else being the installation default values):
listen_addresses = '*'
2) None of the following configurations of the pg_hba.conf file worked (the program runs on 192.168.2.120):
# IPv4 local connections:
#host all all 127.0.0.1/32 md5
host all all 192.168.2.120/24 md5
# IPv4 local connections:
#host all all 127.0.0.1/32 md5
host all all 192.168.2.120 255.255.255.255 md5
# IPv4 local connections:
host all all 127.0.0.1/32 md5
host all all 192.168.2.120/24 md5
# IPv4 local connections:
host all all 127.0.0.1/32 md5
host all all 192.168.2.120 255.255.255.255 md5
I have a Symantec personal firewall installed which I turned off during testing.
The program runs fine on localhost.
Am using the Npgsql .NET library. The Npgsql.Npgsql.Open() call throws an exception, the error text of which is "System.Net.Sockets.SocketException: NO connection could be made because the target machine actively refused it."

Check: 1) the listen_address='*' didn't "take". Make sure you remembered to remove the comment sign (yup, i've seen that mistake manu times). Also, you need to restart the service after you've changed that, perhaps you forgot it? 2) Is there any chance that the postmaster is running on a non-default port? Or that the client is connecting on a non-standard port? 3) Verify that the IP Npgsql connects to is correct. If you're using a DNS name, make sure it resolves right. If all those look right, run a "netstat -na" on the commandline and see if there is a listener to port 5432 and what IP that one is bound to. //Magnus

host all all 192.168.2.120/24 md5
----------------
makes no sense to me, and probably neither to postgresql, it should be:
192.168.2.120/32 # if 192.168.2.120 is your client, this should be
enough
or
192.168.2.0/24 # if you wanted to allow all host in subnet to
validate thru md5, use this
long life, little spam and prosper.

TIP 6: explain analyze is your friend
Try disabling firewall. Because it may prevent any connections to your machine.

The program runs fine on localhost.
Am using the Npgsql .NET library. The Npgsql.Npgsql.Open() call throws an exception, the error text of which is "System.Net.Sockets.SocketException: NO connection could be made because the target machine actively refused it."
Thanks to all who responded. I'm a bit strapped for time now so I won't publish a detailed analysis of what was wrong. Several of the suggestions provided were helpful and more than one thing was wrong with my setup. The program is working now on the client machine.
Thanks again for the help.
