Re: Problems connecting to postgres using JDBC Driver.

Hi Neil.

On postgresql.conf I changed the listen_address to *.
Then commented the first host entry on pg_hba.conf
then restarted the server.

I wasnt able to log to the client on the command line (psql) because or missing or erroneos pg_hba.conf.  So I added again the first host entry and restarted the server again.  This time I was able to log using the client.

So I tried again the java application and I have the same error message!...


BUT  I JUST RECEIVED THE ANSWERED FROM A FEDORA FORUM!!!  I wouldn't have guessed it never!!

It turns out that the pg_hba.conf does not accept names to identify a host, only IPs  and i have the name of one of my computers.  I removed that host line and it works!!!

The person who posted refers to this URL:  http://www.postgresql.org/docs/8.0/interactive/client-authentication.html#AUTH-PG-HBA-CONF

Thanks alot for your help!!

Check the parameter  listen_addresses in the postgresql.conf file to set the correct value for you (may be '*' to test).

Remove or comment the first host entry. I guess it is not a valid CIDR-ADDRESS value ;-)

Restart your server and try again your java application.

Hello.  I need your help.

I have a box running Fedora Core 6. I installed the Postgres Server using yum, so i have the distributing software.

Ever since i installed it im having problems connecting my java applications to the database.

But first thing first:

This is the error message i get when connecting to the database:
Checking if Driver is registered with DriverManager.
Registered the driver ok, so let's make a connection.
Couldn't connect: print out a stack trace and exit.
org.postgresql.util.PSQLException: FATAL: missing or erroneous pg_hba.conf file

        at Connect.main(Connect.java:26)


the pg_hba.conf file is located in:  /var/lib/pgsql/data    and it looks like this:

# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD

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


somewhere I read that i should live a blank line at the very bottom of the file, so i have...  Also, i have checked that each value is separated by a tab.  Also, i read that the PATH and the LD_LIBRARY_PATH should include the path to the postgres configuration.  So on /etc/bashrc i have the following:

export LD_LIBRARY_PATH=$JMFHOME/lib:/var/lib/pgsql/data/:$LD_LIBRARY_PATH
export PATH=/var/lib/pgsql/data/:$PATH


Now, this is the weird thing...  I can connect using the psql client.

psql -t template1 -U damunoz
and then entering the password....

So I have no idea what is going on...  I tested with different drivers with the same results.  My guess is that maybe this has something to do with the Fedora's distribution.  I will post this same message to them as well.

Thanks in advance for your help!
