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

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?


In your pg_hba.conf file, I see some incorrect and confusing lines:

# fine, this allows all dbs, all users, to be trusted from 192.168.0.1/32
# not recommend because of the lax permissions
host    all        all         192.168.0.1/32        trust

# wrong, /128 is an invalid netmask for ipv4, this line should be removed
host    all        all         192.168.0.1/128       trust

# this conflicts with the first line
# it says that that the password should be md5 and not plaintext
# I think the first line should be removed
host    all        all         192.168.0.1/32        md5

# this is fine except is it unnecessary because of the previous line
# which allows any user and any database to connect with md5 password
host    chaosLRdb  postgres    192.168.0.1/32        md5

# wrong, on local lines, an IP cannot be specified
# remove the 4th column
local   all        all         192.168.0.1/32        trust

I suspect that if you md5'd the password, this might work if you trim the lines. To get the md5 you can use perl or the following shell script:

 echo -n 'chaos123' | md5sum
 > d6766c33ba6cf0bb249b37151b068f10  -

So then your connect line would like something like:

my $dbh = DBI->connect("DBI:PgPP:database=chaosLRdb;host=192.168.0.1;port=5433",
    "chaosuser", "d6766c33ba6cf0bb249b37151b068f10");

For more information, here's the documentation of postgres 8.X's pg_hba.conf file.

Documentation: 9.3: The pg_hba.conf File, In your pg_hba.conf file, I see some incorrect and confusing lines: # fine, this allows all dbs, all users, to be trusted from 192.168.0.1/32 # not  This below worked for me: (pg_hba.conf) # TYPE DATABASE USER ADDRESS METHOD # "local" is for Unix domain socket connections only local all all md5 # IPv4 local connections: host all all 127.0.0.1/32 trust host all all 0.0.0.0/0 trust # IPv6 local connections: host all all ::1/128 trust host all all 0.0.0.0/0 trust


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.

6.1 Modifying the postgresql.conf File, Add or edit the following line in your postgresql.conf : listen_addresses = '*'. Add the following line as the first line of pg_hba.conf . It allows access to all  Error Connecting to database FATAL : no pg_hba.conf entry for host"x.x.x.x", user"jiradbuser", database"jiradb", SSL off Cause Client authentication is controlled by a configuration file, which traditionally is named pg_hba.conf and is stored in the database cluster's data directory.


Your postgres server configuration seems correct

host    all         all         127.0.0.1/32          md5
host    all         all         192.168.0.1/32        trust
That should grant access from the client to the postgres server. So that leads me to believe the username / password is whats failing.

Test this by creating a specific user for that database

createuser -a -d -W -U postgres chaosuser

Then adjust your perl script to use the newly created user

my $dbh = DBI->connect("DBI:PgPP:database=chaosLRdb;host=192.168.0.1;port=5433", "chaosuser", "chaos123");

This document describes how to resolve 'FATAL: no pg_hba.conf entry for host' error when you connect through PGAdmin tool. At the last line make a new entry as shown below host all all 0.0.0.0/0 md5 Save and exit the file and restart the postgresql service


To resolved this problem, you can try this.

first you have find out your pg_hba.conf and write :

local all all md5

after that restart pg server:

postgresql restart

or

sudo /etc/init.d/postgresql restart

conf entry for host "127.0. 0.1", user "ambari", database "ambari", SSL off. In addition to @Jon Maestas workaround, add the IP address of the host (on which PostgreSQL server is running) to the pg_hba. conf file and make sure that the method is set to "trust". Can someone help me why this is happening when I'm trying to connect to database or rails s?. In my pg_hba.conf file I have this: # TYPE DATABASE USER ADDRESS METHOD # "local" is for Unix domain socket connections only local all all trust # IPv4 local connections: host all all 127.0.0.1/32 trust # IPv6 local connections: host all all ::1/128 trust # Allow replication connections from localhost


For those who have the similar problem trying to connect to local db and trying like con = psycopg2.connect(database="my_db", user="my_name", password="admin"), try to pass the additional parameter, so the following saved me a day: con = psycopg2.connect(database="my_db", user="my_name", password="admin", host="localhost")

conf entry for host, … SSL off¶. Cause¶. This error means that your PostgreSQL client is configured to connect to without SSL, but PostgreSQL  modifying pg_hba.conf. Within postgresql.conf there is an entry commented out, tcpip_socket = false, uncomment that line and change it to equal true. Now you can modify the pg_hba.conf. Add a new line to that reads the following: host all all XXX 255.255.255.255 trust
