Thread: jdbc pg_hba.conf error
Hi,
I'm a newbee to postgreSQL. Does anyone know what this error means.
I'm trying to run the following java program. I have also included the
java program and the pg_hba.conf file.
java db_connect_pgsql.class
Checking if Driver is registered with DriverManager
Registered the driver ok, making DB connection now
Couldn't connect: print out a stack trace and exit.
org.postgresql.util.PSQLException: A connection error has occurred:
org.postgres ql.util.PSQLException:

# 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 seven forms:
#
# local DATABASE USER METHOD [OPTION]
# host DATABASE USER IP-ADDRESS IP-MASK METHOD [OPTION]
# hostssl DATABASE USER IP-ADDRESS IP-MASK METHOD [OPTION]
# hostnossl DATABASE USER IP-ADDRESS IP-MASK METHOD [OPTION]
# host DATABASE USER IP-ADDRESS/CIDR-MASK METHOD [OPTION]
# hostssl DATABASE USER IP-ADDRESS/CIDR-MASK METHOD [OPTION]
# hostnossl DATABASE USER IP-ADDRESS/CIDR-MASK METHOD [OPTION]
#
# (The uppercase quantities should 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), or a file name prefixed with "@".
# USER can be "all", an actual user name or a group name prefixed with
# "+" or a list containing either. IP-ADDRESS and IP-MASK specify the
# set of hosts the record matches. CIDR-MASK is an integer between 0
# and 32 (IPv4) or 128 (IPv6) inclusive, that specifies the number of
# significant bits in the mask, so an IPv4 CIDR-MASK of 8 is equivalent
# to an IP-MASK of 255.0.0.0, and an IPv6 CIDR-MASK of 64 is equivalent
# to an IP-MASK of ffff:ffff:ffff:ffff::. METHOD can be "trust", "reject",
# "md5", "crypt", "password", "krb4", "krb5", "ident", or "pam". Note
# that "password" uses clear-text passwords; "md5" is preferred for
# encrypted passwords. OPTION is the ident map or the name of the PAM
# service.
#
# 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, or use
# "pg_ctl reload".
# Put your actual configuration here
# ----------------------------------
#
# CAUTION: The default configuration allows any local user to connect
# using any PostgreSQL user name, including the superuser, over either
# Unix-domain sockets or TCP/IP. If you are on a multiple-user
# machine, the default configuration is probably too liberal for you.
# Change it to use something other than "trust" authentication.
#
# If you want to allow non-local connections, you need to add more
# "host" records. Also, remember TCP/IP connections are only enabled
# if you enable "tcpip_socket" in postgresql.conf.
# TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD
# IPv4-style local connections:
#host all all 127.0.0.1 255.255.255.255 trust
# IPv6-style local connections:
#host all all ::1
ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff trust
# Using sockets credentials for improved security. Not available everywhere,
# but works on Linux, *BSD (and probably some others)

No, only when you want to change network access permissions for the installation as a whole. See the manuals for full details. Of course, if you have different rules for each database you'll need to make more changes than if you have two or three rules that apply to a whole installation. With 8.2 you can control access to databases via ROLEs as well as access to schemas,tables etc. -- Richard Huxton Archonet Ltd

Since you aren't specifying a host (with -h), that command uses a Unix socket connection and only looks at lines in pg_hba.conf that begin with "local".

(Seeing that that error message specifies that SSL is off.) Please remember to SIGHUP or restart the postmaster after changing it.

As super-user (postgres) you have to create the user in Postgres, then Grant access. In other words, if the pg_hba.conf file specifies a user who does not exist, "user brakesh does not exist" will cause a failure to connect as well. Every connection to a database, has to have a user associated with the session. So the fact that he has connected to at least one database, means he's gotten far enough to connect and create the proper ID/Authentication. Actually, I wonder if 'after' he's changed the pg_hba.conf file if he's been restarting the postgres process? Which is 'session' associated. Everytime you change the pg_hba.conf file, you have to restart postgres, don't you?

I've seen similar problems resolved by discovering that (1) the DBA
was editing the wrong copy of the pg_hba.conf file, or (2) there was
actually more than one postmaster running on the machine.
Check "ps" for multiple postmasters. Put a deliberate error in the
pg_hba.conf file and verify that the postmaster fails to restart.

Ok,
I confirmed that I'm editing the right pg_hba.conf file. I made sure that there are no other postmasters running. I made sure that there is a user called 'brakesh'. I restart the postmaster everytime I make any changes to pg_hba.conf file. But still same results!

Hi,
Here's what happens when I specify the port number
[brakesh@lnx383 ~]$ psql -U brakesh -p 5000 -h 127.0.0.1 -d testing123
psql: could not connect to server: Connection refused
Is the server running on host "127.0.0.1" and accepting
TCP/IP connections on port 5000?
I have the listen_address in
postgresql.conf
file set as follows:
#---------------------------------------------------------------------------
# CONNECTIONS AND AUTHENTICATION
#---------------------------------------------------------------------------
# - Connection Settings -
listen_addresses = '*' # what IP address(es) to listen on;
# comma-separated list of addresses;
# defaults to 'localhost', '*' = all
# (change requires restart)
#port = 5432 # (change requires restart)
max_connections = 100 # (change requires restart)

Since that command without "-h 127.0.0.1" does work, the clear implication is that somehow there is a postmaster listening on port 5000 to Unix sockets and a different postmaster, presumably with a different pg_hba.conf, listening on port 5432 on 127.0.0.1. -- Oliver Elphick olly@lfix.co.uk Isle of Wight http://www.lfix.co.uk/oliver GPG: 1024D/A54310EA 92C8 39E7 280E 3631 3F0E 1EC0 5664 7A2F A543 10EA ======================================== Do you want to know God? http://www.lfix.co.uk/knowing_god.html

W/out specifying a -h switch, postgres defaults to using a UNIX domain socket, meaning AF_UNIX and not AF_INET. There is a big difference. Using -h 127.0.0.1 is the localhost not necessarily 'local' from the context of postgres. W/out looking into the details, I think 'local' is referring to AF_UNIX. In other words, without specyfing the -h switch, when you have connected, do a "netstat -an" you'll see there are no TCP/IP(AF_INET) sockets connected, but rather there is a AF_UNIX socket connected which will be somewhere in /tmp/blah.s.psostgres.5000 or something similar.

5000 being a nonstandard port number, it's certainly possible that the
kernel is filtering this connection attempt. "Connection refused" might
mean either that there's no process listening to TCP port 5000, or that
the kernel rejected the connection before looking for a listening process.
In any case it seems highly probable that you do have two postmasters
running on this machine, one at port 5000 and one at port 5432. The
psql calls without an explicit -p switch would have defaulted to port
5432 unless you've done something strange to your installation.

Starting the postmaster with a "-i" option did the trick.
-i Allows clients to connect via TCP/IP (Internet domain) connections. Without this
option, only local Unix domain socket connections are accepted. This option corre-
sponds to setting tcpip_socket=true in postgresql.conf.
--tcpip-socket=false has the opposite effect of this option.
However, this still does not solve my problem of having a java application connect to the postgres DB server. I get the following error:
Couldn't connect: print out a stack trace and exit.

-i Allows clients to connect via TCP/IP (Internet domain) connections. Without this
option, only local Unix domain socket connections are accepted. This option corre-
sponds to setting tcpip_socket=true in postgresql.conf.
--tcpip-socket=false has the opposite effect of this option.

"Connection refused" might mean either that there's no process listening to TCP port 5000, or that the kernel rejected the connection before looking for a listening process. In any case it seems highly probable that you do have two postmasters running on this machine, one at port 5000 and one at port 5432. The psql calls without an explicit -p switch would have defaulted to port 5432 unless you've done something strange to your installation. regards, tom lane
