Hello All, It seems to me that a solution for this specific problem (Man-in-the-middle) can be found via SSH Tunneling...;-) Using OpenSSH of course...;-) If you are using (redhat) linux, I believe there is a great book online found at http://www.openna.com called Securing and Optimizing Redhat Linux. There are a bunch of other ways that you can do... But as for the original thread... I think you can encrypt passwords in postgres...;-) But what do I know..;-) > I was referring to a different aspect of security.
