I am trying to connect a device (on the same network) to my server so that it
can access the PostgreSQL database. When it tries to connect I get this
error at catalina.out:
org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create
PoolableConnectionFactory (Connection refused. Check that the hostname and
port are correct and that the postmaster is accepting TCP/IP connections.)
at
org.apache.tomcat.dbcp.dbcp.BasicDataSource.createDataSource(BasicDataSource.java:1225)
Caused by: org.postgresql.util.PSQLException: Connection refused. Check that
the hostname and port are correct and that the postmaster is accepting
TCP/IP connections.

org.postgresql.core.v3.ConnectionFactoryImpl.openConnectionImpl(ConnectionFactoryImpl.java:136)
Here is my network info:
* Server (where apache-tomcast resides) 192.168.5.5
* Device (unix based) 192.168.5.127
Software versions:
* Server - Debian 5
* Postgres - 8.4
* Java (on server) - 1.6.0_17
* Apache-tomcat - 6.0.20
1) I ran netstat on client and server.

2) I checked pg_hba and the connections are set:
# IPv4 local connections:
host all all 127.0.0.1/32 trust
host all all 192.168.5.5/24 trust
host all all 192.168.5.127/24 trust
# IPv6 local connections:
host all all ::1/128 trust
3) postgres.conf is configured to listen on to all connections.
# - Connection Settings -
listen_addresses = '*'
port = 5432
What else can I check to get to the bottom of this bug?
