PostgreSQL 8.3.7 Clint to Server Connection Problem! - Mailing list pgsql-novice

Hello:

Note: English 2nd language, so forgive errors in English.
====

CentOS 5.2

-------------------------
PostgreSQL Server (eth1: 10.43.48.101). The following modules are
installed:

postghresql-libs-8.3.7, postgresql-8.3.7, postgresql-server-8.3.7,
pgAdmin3-1.8.4

"postgresql.conf":
     listen_addresses    =    '*
"pg_hba.conf"
    host   all   all   10.43.48.0/16

"/etc/services"
    postgresql         5432/tcp
    postgresql         5432/udp
-------------------------

PostgreSQL Client (eth1: 10.43.48.1). The following modules are installed:

postghresql-libs-8.3.7, postgresql-8.3.7 & pgAdmin3-1.8.4

"postgresql.conf" & "pg_hba.conf" has no entry in the PostgreSQL Client.

-------------------------

On the PostgreSQL Server (IP: 10.43.48.101), I can connect to the
PostgreSQL & create a "Server" listening on port "5432" using "pgAdmin3".

PROBLEM:

When trying to connect to the PostgreSQL Server from PostgreSQL Client,
get an error message:

"Could not connect to the server: No route to the host Is the server
running
on host "10.43.48.101" and accepting TCP/IP connections on 5432?"

First of all, I can ping the PostgreSQL server from the Client machine.
I have researched the Internet and found lots of reference to this error
but nothing helped.

1. Am I installing all the necessary modules/files on the PostgreSQL
Client machine?
2. Any suggestion, help?
