Connection à distant postgresql

Bonjour,
J'ai un petit problème j'arrive pas à me connecter à ma base de donnée postgresql et je ne parviens pas à trouver la  solution...

Bon voilà, j'ai un postgresql installé sur mon ordinateur (ordinateur  A) sur un serveur linux. Je voudrais me connecter à cette base depuis un post windows 7(ordinateur B) ,qui se trouve sur le même réseau que l'ordinateur A.

Pour ça, j'ai commencé par modifier les dossiers (sur ordinateur  A) postgresql.conf: listen_address = ' * '
pg_hba.conf: host all postgres 192.168.10.(ip  de l'ordinateur B)/0 trust
Pour me connecter à cette base j'utilise un logiciel TALEND qui permet d'extraire les données des la base postgreql vers une base qui se trouve sur l'ordinateur B?

Pour me connecter dans le talend,les paramètres de connexion est la suivante: 
user:postgres
mot de passe:*****
server:192.168.10.(ip computerA)
port:5432
DB:db_name

Et j'ai cet erreur:Echec de la connexion Vous devez modifier les paramètres de la base de données.
  java.lang.RuntimeException: org.postgresql.util.PSQLException: Connexion refusée. Vérifiez que le nom de machine et le port sont corrects et que postmaster accepte les connexions TCP/IP.

Merci d'avance.

Re : Connection à distant postgresql

Vérifiez que vos firewall (ordinateur a et b) ne sont pas actifs.

Si vous pouvez, vérifiez que les processus postgres sur ordinateur a sont bien présents.
Dans le postgresql.conf d'ordinateur a, que vaut le parametre "port" ?

Cordialement,

Sébastien.

Re : Connection à distant postgresql

les pare-feu sont désactivé
Comme l'ordinateur est un serveur il tourne tout les jours et il y a des application qui l'utilisent
le port est 5432 mais il est commenté

Re : Connection à distant postgresql

pouvez vous nous copier le contenu du pg_hba.conf entier du serveur ?
(le pg_hba.conf qui correspond à la requête : select  name , setting from pg_settings where  name like '%hba%';)
et pouvez vous me donner le résultat de la requête suivante :
select  name , setting from pg_settings where  name like '%listen_%';

# PostgreSQL Client Authentication Configuration File
# ===================================================
#
# Refer to the "Client Authentication" section in the
# PostgreSQL documentation for a complete description
# of this file.  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", "samerole", 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 (IPv4) 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",
# "krb5", "ident", "pam" or "ldap".  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
# "samerole" 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

# On autorise le user local postgres a faire tout ce qu'il veut (socket unix uniquement)
# sans aucune saisie de mot de passe
local   all         postgres                               ident sameuser

# On autorise les connections locales des autres users via la saisie d'un mot de passe
local   all         all                                    md5
host    all         all         127.0.0.1/32               md5

Re : Connection à distant postgresql

remplacez la derniere ligne :
host    all         all         127.0.0.1/32               md5
par celle ci :
host    all         all         0.0.0.0         0.0.0.0          md5

Re : Connection à distant postgresql

dans le postgresql.conf, il faut mettre le paramètre listen_addresses='*' puis relancer l'instance pour que ce soit pris en compte.
Une fois que c'est fait pouvez vous refaire la requête : select  name , setting from pg_settings where  name like '%listen_%';

Re : Connection à distant postgresql

vérifiez si dans votre postgresql.conf vous n'auriez pas listen_addresses plusieurs fois.
Et vérifiez aussi qu'il s'agit  du bon postgresql.conf que vous modifiez : select  name , setting from pg_settings where  name like '%config_%';

#
# This file consists of lines of the form:
#
#   name = value
#
# (The '=' is optional.)  White space may be used.  Comments are introduced
# with '#' anywhere on a line.  The complete list of option names and
# allowed values can be found in the PostgreSQL documentation.  The
# commented-out settings shown in this file represent the default values.
#
# Please note that re-commenting a setting is NOT sufficient to revert it
# to the default value, unless you restart the server.
#
# Any option can also be given as a command line switch to the server,
# e.g., 'postgres -c log_connections=on'.  Some options can be changed at
# run-time with the 'SET' SQL command.
#
# This file is read on server startup and when the server receives a
# SIGHUP.  If you edit the file on a running system, you have to SIGHUP the

Re : Connection à distant postgresql

Si vous êtes en 9.4 ou plus, il s'agit peut être d'une commande ALTER SYSTEM qui aurait été effectuée. Vous pouvez vérifier dans le fichier postgresql.auto.conf
