PostGreSQL: доступ из сети

При установке PGSQL сервера столкнулся с проблемой доступа из локальной сети. Кто может подсказать в чем проблема???

pg_hba.conf

Код:

# Database administrative login by UNIX sockets
local   all         postgres                          ident

# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD

# "local" is for Unix domain socket connections only
local   all         all                               ident
# IPv4 local connections:

# -----------------------------
# PostgreSQL configuration file
# -----------------------------
#
# This file consists of lines of the form:
#
#   name = value
#
# (The "=" is optional.)  Whitespace may be used.  Comments are introduced with
# "#" anywhere on a line.  The complete list of parameter names and allowed
# values can be found in the PostgreSQL documentation.
#
# The commented-out settings shown in this file represent the default values.
# Re-commenting a setting is NOT sufficient to revert it to the default value;
# you need to reload the server.
#
# This file is read on server startup and when the server receives a SIGHUP
# signal.  If you edit the file on a running system, you have to SIGHUP the
# server for the changes to take effect, or use "pg_ctl reload".  Some
# parameters, which are marked below, require a server shutdown and restart to
# take effect.
#
# Any parameter can also be given as a command-line option to the server, e.g.,
# "postgres -c log_connections=on".  Some parameters can be changed at run time
# with the "SET" SQL command.
#
# Memory units:  kB = kilobytes        Time units:  ms  = milliseconds

#                                                   h   = hours

Вроде все правильно, но на клиент машинах пишет:

Не удалось подсоединиться к серверу: Connection refused
Работает ли сервер на хосте "ип_хоста" и принимает ли TCP/IP соединения по порту 5432?

з.ы. Фаерволов нет. Сервер стоит на Ubuntu 9.10

Renegade · 16.02.2010

Connection refused явно намекает на то что надобы посмотреть что пишется в логах.

Я дусаю что для начала не мешало бы отключить md5

Shaaarnir · 17.02.2010

я бы подредактировал pg_hba.conf для начала так (если заработает, изменить нужно будет):
local all all trust
host all all 0.0.0.0/0 trust

Все остальное или закаментить или удалить.

F.a.T.a.L. · 17.02.2010

Вопрос решен. Проблема как всегда оказалась "гениальной". В файле Postgresql.conf строка listen_addresses была закоментированна. Удалил лишний диез и все прекрасно заработало!!!

з.ы. C md5 там как раз все в порядке)

з.ы.ы. Всем спасибо за советы
