Hello, Monique,


well, you have to have a user account on the server, there is the
question of the postgresql username and md5 encrypted password. it is an
ssh connection. the port is redirected via the nat whatever it is in
the router to that server.

Should I shut it down quick? I am not too (at all) hot on security
across the net since this is first time that I have ever done this.

Seriously, what would you suggest as my next step to improve security?
