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: FATAL: no pg_hba.conf entry for host "127.0.0.1", user "b rakesh", database "testing123", SSL off at org.postgresql.jdbc1.AbstractJdbc1Connection.openConnectionV3(Abstrac tJdbc1Connection.java:337) at org.postgresql.jdbc1.AbstractJdbc1Connection.openConnection(AbstractJ dbc1Connection.java:214) at org.postgresql.Driver.connect(Driver.java:139) at java.sql.DriverManager.getConnection(DriverManager.java:559) at java.sql.DriverManager.getConnection(DriverManager.java:189) at db_connect_pgsql.main(db_connect_pgsql.java:25) Here is my pg_.conf file # 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.
