setting up remote rails

I've got a remote machine on my network which has Ubuntu as the OS. I
run my testserver on it with all my current PHP sites. All I have to
type on my main Vista Machine as the URL is "http://testserver" and it
takes me to the index page i've created with links to all my sites on
that remote Ubuntu machine.

My question is:
I've setup RoR on that machine, but when I type testserver:3000 it
wont access that page. On the machine itself, I am able to see my RoR
project, but not on my main machine. I'm even able to SSH into the
testserver to work on the project files. How do I go about setting
that up?

My second Question is, Where are the config files to tell RoR to use
the MySQL database I currently have setup on the testserver that
phpmyadmin is also using? I have edited the database.yml file to
include the correct login information and the mysql adapter but it's
still not connecting properly to the database. Is there a certain file
I can setup the paths in for my MySQL db?

use) to forward your mongrel on port 3000.

as long as your database.yml is configured correctly you only need to
make sure that you have sufficient rights to access that database. run
  mysql -uroot -ppassword
and adjust settings (e.g. create database, grant access for chosen
