Could firewall be a factor?

Also 10.2.1.4 looks like a local address, but you said "remote machine"... Perhaps having more details on your environment/configuration would be helpful.

Hi Michael,

its the other machine, not the same.

Here is my hba_conf file.

# PostgreSQL Client Authentication Configuration File
# ================================================== =
# Refer to the PostgreSQL Administrator's Guide, chapter "Client
# Authentication" for a complete description. A short synopsis
# follows.
# This file controls: which hosts are allowed to connect, how clients
# are authenticated, which PostgreSQL user names they can use, which
# databases they can access. Records take one of these forms:

# local DATABASE USER METHOD [OPTION]
# host DATABASE USER CIDR-ADDRESS METHOD [OPTION]
# hostssl DATABASE USER CIDR-ADDRESS METHOD [OPTION]
# hostnossl DATABASE USER CIDR-ADDRESS METHOD [OPTION]

# (The uppercase items must be replaced by actual values.)

# The first field is the connection type: "local" is a Unix-domain socket,
# "host" is either a plain or SSL-encrypted TCP/IP socket, "hostssl" is an
# SSL-encrypted TCP/IP socket, and "hostnossl" is a plain TCP/IP socket.

# DATABASE can be "all", "sameuser", "samegroup", a database name, or
# a comma-separated list thereof.

# USER can be "all", a user name, a group name prefixed with "+", or
# a comma-separated list thereof. In both the DATABASE and USER fields
# you can also write a file name prefixed with "@" to include names from
# a separate file.

# CIDR-ADDRESS specifies the set of hosts the record matches.
# It is made up of an IP address and a CIDR mask that is an integer
# (between 0 and 32 (IPv6) or 128(IPv6) inclusive) that specifies
# the number of significant bits in the mask. Alternatively, you can write
# an IP address and netmask in separate columns to specify the set of hosts.

# METHOD can be "trust", "reject", "md5", "crypt", "password",
# "krb4", "krb5", "ident", or "pam". Note that "password" sends passwords
# in clear text; "md5" is preferred since it sends encrypted passwords.

# OPTION is the ident map or the name of the PAM service, depending on METHOD.
# Database and user names containing spaces, commas, quotes and other special
# characters must be quoted. Quoting one of the keywords "all", "sameuser" or
# "samegroup" makes the name lose its special character, and just match a
# database or username with that name.

# This file is read on server startup and when the postmaster receives
# a SIGHUP signal. If you edit the file on a running system, you have
# to SIGHUP the postmaster for the changes to take effect. You can use
# "pg_ctl reload" to do that.

# Put your actual configuration here
# ----------------------------------
# If you want to allow non-local connections, you need to add more
# "host" records. In that case you will also need to make PostgreSQL listen
# on a non-local interface via the listen_addresses configuration parameter,
# or via the -i or -h command line switches.

# TYPE DATABASE USER CIDR-ADDRESS METHOD

# IPv4 local connections:
host all all 127.0.0.1/32 md5
host Admin all 10.2.1.4/32 md5

host Admin all 10.2.1.4/32 md5
# Queries & Admin for development over VPN GMG 20060613
host all all 10.2.1.4/32 md5

# IPv6 local connections:
#host all all ::1/128 md5


Iam connecting to the server 10.2.1.4 using odbc_connect(). It is gives me the same error “unable to connect to the server.

This is my code.
[PHP]<?php

$connection_string = 'DRIVER={PostgreSQL};SERVER=10.2.1.4:5432;DATABASE =Admin';
$user = 'postgres';
$pass = 'post2007!';

$connection = odbc_connect( $connection_string, $user, $pass );

if($connection)
{
echo "connected successfully...!";
}
else
{
echo "unable to connect to the server..!";
}
?> [/PHP]

It is gives me the same error “unable to connect to the server...!.
