Sandhya, You have mentioned 3 different IP addresses for your server in this topic so far. Your pg_hba.conf entry says "10.0.3.67/32" - which means only that IP can connect - the IP address/range in pg_hba.conf should be your client IP (if this is on the same server as PGSQL, the best way is to use 127.0.0.1 (the system default localhost IP)). Your application appears to be trying to connect to 10.0.0.205, which is different to the one you've just said your server is 10.0.2.56. Do an "ifconfig" on the console and find out what network adapters there are in your server, and what IPs they're bound to - then in your postgresql.conf bind PostgreSQL to one of them (if you have multiple adapters) (using the listen_address=... option - then you can use that IP to specify as the connection IP in your application. But you need to get some consistency in the IPs your server is listening on, and your application is trying to connect to.

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.
