Postgresql – no pg_hba.conf entry for host

database-permissionsperlpostgresql

I get following error when I try to connect using DBI

DBI connect('database=chaosLRdb;host=192.168.0.1;port=5433','postgres',...) 
failed: FATAL:  no pg_hba.conf entry for host "192.168.0.1", user "postgres", database "chaosLRdb", SSL off

Here is my pg_hba.conf file:

# "local" is for Unix domain socket connections only
local   all         all                               md5
# IPv4 local connections:
host    all         all         127.0.0.1/32          md5
# IPv6 local connections:
host    all         all         ::1/128               md5

host    all         postgres    127.0.0.1/32          trust

host    all        postgres     192.168.0.1/32        trust

host    all        all         192.168.0.1/32        trust

host    all        all         192.168.0.1/128        trust

host    all        all         192.168.0.1/32        md5

host    chaosLRdb    postgres         192.168.0.1/32      md5
local    all        all         192.168.0.1/32        trust

My perl code is 

#!/usr/bin/perl-w
use DBI;
use FileHandle;

print "Start connecting to the DB...\n";

@ary = DBI->available_drivers(true);
%drivers = DBI->installed_drivers();
my $dbh = DBI->connect("DBI:PgPP:database=chaosLRdb;host=192.168.0.1;port=5433", "postgres", "chaos123");

May I know what i miss here?

Best Answer

If you can change this line:

host    all        all         192.168.0.1/32        md5

With this:

host    all        all         all                   md5

You can see if this solves the problem.

But another consideration is your postgresql port(5432) is very open to password attacks with hackers (maybe they can brute force the password). You can change your postgresql port 5432 to '33333' or another value, so they can't know this configuration.
