Hello,
From Windows NT, I have a problem to connect to my PostgreSQL 6.5.2 server
running on an i386-based Linux, Red Hat 6.1, using JDBC. The java class I
used for testing was from the src/interfaces/jdbc/example/basic.java.
First of all, I know postmater runs with -i turned on. The standard
port number was used.
Secondly, I have $PGDAT/pg_hba.conf set up to allow everyone from my subnet
to connect to the server.
# pg_hba.conf
host all 192.168.50.158 255.255.255.255 trust
host all 192.168.50.0 255.255.255.0 trust
Everything runs okay on Linux machine using JDK1.1.8.
I copied the jdbc6.5-1.2.jar to my NT machine. While I run the "basic",
it failed. Jdk1.2 was used on the NT.
What's the problem?

When I ran the same thing from the MS NT machine with the IP
