setting up PostgreSQL on Linux RHL9 to allow ODBC connections from Windows

There's nothing on the server side that needs to be configured for
Windows clients to access Postgres via ODBC. As long as TCP/IP is turned
on. Just add a data source and configure the server
ip/name/port/database/etc.

Hi,

All you need is the Windows ODBC driver, which you install on the
client machine, and then configure it to talk to the Linux server on
port 5432 (set by default).

--Ray.

Most of the documentation is talking about setting up Unix to Unix odbc, or
Windows to Windows, not Windows to Unix/Linux.

Some documentation talks about installing the "full" distribution on
Windows, but I just want to allow some Windows software that "speaks" ODBC
(SilkTest) to be able to connect to an existing database.

In the document
http://gborg.postgresql.org/project/psqlodbc/genpage.php?howto-redhat, it
says to download rpms and install them, but I don't really see any rpms for
this. I see source distributions at
http://www.postgresql.org/ftp/odbc/versions/src/, but nothing for version
7.4, just 7.3 and 8.0. I am reluctant to upgrade to 8.0, as I am not sure
it is stable yet, and my installation is running so well.

The howto-redhat document also talks about running:

psql -d template1 -f /usr/share/pgsql/odbc.sql

to modify template1, but what about existing databases?

I'm somewhat nervous about doing anything to potentially mess up anything
on my Linux server, as this is a production database.

Then, you have to set up the iodbc driver manager, etc. On this server, I
have had some issues with using rpm's in the past, and have often had to
resort to building things myself (configure, make, etc.)

I'm also not sure about how to specify a DSN to do the connection from the
Windows side (I'm primarily a Unix/Linux person).

Does anyone have any specific advice/experiences to offer on setting this
up as simply as possible?

Thanks,
Susan

Not quite correct. TCP needs to be turned on AND an according entry in
pg_hba.conf needs to be set up - otherwise the server will just decline to
talk to the client.
Also - if you're on XP you might want to check the "firewall" settings - which
if configured wrong could potentially block connections on port 5432. If you
have a default setup of XP it should be fine though.

hi, if the client machine is another linux , what is the correct way to
configure ODBC

thanks
