(192.168.0.34 is my IP) I rectified this by editing the /var/lib/pgsql/pg_hba.conf to add host all 192.168.0.0 255.255.255.0 trust at the end of the file.... I know this is not ideal, with no security, but then , i can connect using ip... But i am still not able to connect thru ODBC on Win95... any solutions ? venu
That worked for me... I made the change in my hba file for the host that needs to connect and it works. I wish I had enough experience in that matter to help you out, but I don't...

Here is a check list.
ODBC Driver Data Source Checks
1.Valid and resolvable hostname.
2.Valid port number. (default is 5432)
3.Valid and existing database name.
4.Valid user name.
5.Valid password for the specified user. (Required iff pg_hba.config is set
to password authenticate your client.)
PostgreSQL Server Checks
1.Postmaster must be running.
2.Postmaster must run with the -i option to allow remote connections.
3.The pg_hba.conf file in $PGPATH/data directory must be configured to allow
your remote host to connect.
The following line pg_hba.conf will allow all external systems pasworded access to
your all databases.
host all 0.0.0.0 0.0.0.0 password
You may want to mask the IP.
I assume your version of the driver is something greater than. 6.30.0036
