Re: Connecting Postgres using other network

Just to check, you are using a non-standard port (6432 - the standard is
5432)?

Hello Everyone

I have installed Postgres server in a network and i am trying
to use the database using
Java code from other network.

I have set the tcp_ip=true in postgresql.conf file.
I have also add the follwing line in the pg_hba.conf

host all all 127.0.0.0
255.255.255.255 trust

Then i start the server in port 6432.

After that i want to access the application using the following
javacode.

import java.sql.*; // All we need for JDBC
import java.text.*;
import java.io.*;
public class HelloPost
{
Connection db; // A connection to the database
Statement sql; // Our statement to run queries
with
DatabaseMetaData dbmd; // This is basically info the
driver delivers
// about the DB it just connected
to. I use
// it to get the DB version to
confirm the
// connection in this example.
public HelloPost()
throws ClassNotFoundException, SQLException
{
String database = "test";
String username = "abc";
String password = "xyz";
try{
Class.forName("org.postgresql.Driver"); file://load the
driver
db =
DriverManager.getConnection("jdbc:postgresql://abc.csse.uts.edu:6432:tes
t",
username,
password); file://connect
to the db
dbmd = db.getMetaData(); file://get MetaData to confirm
connection
System.out.println("Connection to
"+dbmd.getDatabaseProductName()+" "+
dbmd.getDatabaseProductVersion()+"
successful.\n");
sql = db.createStatement(); file://create a statement that
we can use later
}catch (ClassNotFoundException e) {
System.err.println( "Driver not found: " + e + "\n"
+ e.getMessage() );
}
db.close();
}
public static void main (String args[])
{
try
{
HelloPost demo = new HelloPost();
}
catch (Exception ex)
{
System.out.println("***Exception:\n"+ex);
ex.printStackTrace();
}
}
}

But this give me the following error

Exception: org.postgresql.util.PSQLException: Connection
refused. Check that the hostname and port are correct and that the post
accepting TCP/IP connections.
Connection refused. Check that the hostname and port are correct
and that the postmaster is accepting TCP/IP connections.

Can anyone please tell me where is the error. what should i doo
..

regards

Shayer
