Thanks Robin. What u said is right! But my problem is i am not trying connecting from any remote client. In my ConnectionInfo if i mention the host as, host=localhost.The connection is successful. But the same if i give my localsystem IP where my server is running.. host = 10.0.2.56(my localhost IP). The Connection is failed. Why is this so?Whether i need to give only localhost in my application (or) why it is not accepting when i gave IP of the same system(When the entry of this IP is already present in pg_hba.conf file)? ----- Original Message ----- From: "Robin Iddon" <robin@xxxxxxxxxx> To: "sandhya" <sandhyar@xxxxxxxxxxxxxx> Cc: "Postgres" <pgsql-admin@xxxxxxxxxxxxxx> Sent: Monday, March 20, 2006 2:28 PM Subject: Re: [ADMIN] reg:conninfo > Try looking at the manual for the postmaster process ... > > A simple way of achieving what you want is adding the -i option to the > postmaster command line which allows TCP/IP connections.
