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..;-)
