Обсуждение: Access PostgreSQL server via SSL/Internet
Is anybody considering this? So that people can write program which access a database via the Internet. What I'm getting at is that we have applications which run on our Intranet. They query and update databases. There is interest in a work at home solution. Since the company has multiple T1 Internet connections, they are interested in allowing people to use their home ISP to connect. We are looking at a VPN solution as well, but they all seem to have a "per seat" or "concurrent use" restriction. The more users, the higher the cost. Also, some ISPs have stated that using a VPN over their facility is forbidden and will result in termination of the service. Another possibility is to simply use a secure Web server and rewrite the applications as CGI's or something similiar. More of a curiousity question at present, John

It is trivial to connect clients and servers across an ssh-piped
connection. I'm not sure of the details as far as getting things set up
to be automated for turnkey installations.

That's something that isn't necessarily a good idea. Also, ssh-piped connections are decent to setup, but you must always ssh in before you want to do anything else.

I just found something called "stunnel" which may do the trick. John

Actually I'm pretty sure you can get around this problem with host keys, but I haven't tried that. -- -Alfred Perlstein - [bright@wintelcom.net|alfred@freebsd.org] "I have the heart of a child; I keep it in a jar on my desk."

I have a very rough outline so far, but I don't want to put down too much work into it until I know I am documenting the right thing (the version that will eventually go in, that is). But it's on it's way. //Magnus

Here is a patch against the same cvs tree as the SSL patch (Aug 20). I hope I didn't mess the SGML up too bad, but somebody should definitly look that over. I tried to steal as much as I could from around :-) This patch updates: * Installation instructions (paragraph on how to compile with openssl) * Documentation of pg_hba.conf (added "hostssl" record docs) * Libpq documentation (added connection option, documentation of PQgetssl() function) * Add section on SSL to "Server Runtime Environment" If you beleive any particular area needs more attention, please let me know. //Magnus

Applied. Thanks. I always love doc patches.
