I have seen you postgresql.conf and pg_hba.conf.
Your postgresql.conf file is fine.
Now see your pg_hba.conf. There are two lines in it
host    all         all         127.0.0.1/32          md5 
host     all        all        192.168.3.0/24          trust

Remove the line
host    all         all         127.0.0.1/32          md5 

or alternatively remove both the lines and replace with 
host     all        all        0.0.0.0/0          trust

Restart your postgresql service. That's it!!!

i have the same problem.
i'm currently using version 3.0.3 update 4.
i tried to do the above instruction but it didn't work.

Close all Application
1. I am assuming that you have made necessary editing of pg_hba.conf and postgresql.conf
2. Note the IP Address of the server. Say for example: 192.168.1.4
3. Open C:/NewGenLibFiles/HibernateConfig/dbConnection.xml using wordpad. You will have one line looking like this jdbc:postgresql://localhost:5432/newgenlib
Change it to
jdbc:postgresql://192.168.1.4:5432/JSS
Means, you are replacing localhost with IP address of the server
4. Start Apache Tomcat Server
5. Follow this step as it is: Open NewGenLib Application. Go to  Utilities -> Reports. And click on Launch Desktop

Can you attach your pg_hba.conf and postgresql.conf files?
We can examine and send you back the updated ones

here they are:

pg_hba.conf
postgresql.conf

[Verus Open Source Support]

Hi,
Your postgresql.conf is fine. It does not need any editing
However please see pg_hba.conf. It needs editing. I edited it for you. I am attaching the same
1. Please download it and replace your old pg_hba.conf
2. Restart postgresql service (Control Panel->Administration tools->Services)
3. Start Apache Server. Launch Application and also Launch Desktop as mentioned in previous email

i replaced my pg_hba.conf with the one you edited but it didn't work.
i'm still getting unable to open application from a client computer but i can open the ngl desktop within the server.
when i edit the dbconnection and replace localhost with IP address, i get "Data base is not connecting properly" message.

Check if you have a firewall running on your server. If yes, add exception for TCP/UDP(both) port 5432 and try again

the firewall is turned off.

[Verus Open Source Support]

Did you restart the Postgresql service after making the changes in pg_hba.conf
Pls check line 67 of pg_hba.conf file, it must be similar to the one shown below

host    all         all         0.0.0.0/0          trust

Can you send your Teamviewer ID and password to support<attherate>verussolutions.biz
Please give Teamviewer access for both the server and the client(from where the NGL Desktop is not running)
So that this issue can be examined
