Hey guys, I'm trying to get a VB program to make a client connection to my PostgreSQL server running on an
Ubuntu 10.10 server. Here's what I've done: Client side - installed and registered the OLE DB .dll's from the PostgreSQL OLE DB Provider project. server side - the configuration described here: https://help.ubuntu.com/10.10/serverguide/C/postgresql.html --------------- Have added this line to postgresql.conf: listen_addresses = '*, 144.96.80.35, localhost' I've also tried this as simply: listen_addresses = '144.96.80.35, localhost' also, port = 5432 -------------- I have added the following to pg_hba.conf: # IPv4 local connections: host all all 144.96.80.35 255.255.255.0 md5 local all postgres md5 -------------- I've got the following code going in VB: Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Const connString As String = "Provider=PostgreSQL; Server=144.96.80.35; User Id=postgres;Password=postgres;" Dim theOleDBconnection As New OleDb.OleDbConnection theOleDBconnection.ConnectionString = connString theOleDBconnection.Open() End Sub End Class So when the project opens up, it should make the connection and display the form. What happens is that I get an error... OleDbException was unhandled could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "" and accepting TCP/IP connections on port 5432? --------------------------- So, obviously I've got something configured incorrectly. I'm troubled that the VB error seems to show a null value for the host. Shouldn't that be the Server value in the connection string? Thanks to all for any help.
