OpenVPN configuration on Ubuntu 8.04 Server

I am trying to install OpenVPN (configure, really) on Ubuntu 8.04 server, and am having problems with the initial configuration. I have read several howtos about the initial process, but they all seem to be outdated. For example, the easy-rsa directory has a 1.0 and 2.0 subdirectory, now, which is not indicated in the current instructions.

Can anyone provide some up-to-date guidance on how to initially configure OpenVPN? Some specific questions I have:

Where are the commands supposed to be issued from? /etc/openvpn/easy-rsa/ or /etc/openvpn/easy-rsa/2.0/
Why does the ". ./vars" command not seem to do anything?
What does the "export EASY_RSA="`pwd`"" line do? (or what is it SUPPOSED to do?)
How can I ensure the vars file is sourced appropriately?

I'm reasonably new to linux/ubuntu, but I have come a long way in the last 6 months. I'd appreciate step-by-step thoughts, but a "big picture" might also be helpful.

BTW, ultimately, I want to be able to access my home network files while on travel (samba shares), AND be able to use my home server as a web proxy while on the road. Walk then run, though... any thoughts on getting OpenVPN working?

I figured most of this out, but I still have a lot of questions about bridging.

Just to close the loop on this... First, I copied all the files from the /2.0 subdirectory into the /easy-rsa directory. I also created a /keys subdirectory (KEY_DIR) inside of /easy-rsa.

I edited the vars file to include all my parameters, and edited the EASY_RSA value from `pwd` to

export EASY_RSA="/etc/openvpn/easy-rsa"

Then, for every script I wanted/needed to execute, I added

. ./vars

to the beginning of the script, and executed the scripts from within the /easy-rsa directory. This addition to the scripts ensured that each script included all the appropriate defaults for the key generation scripts. Keys were then created inside the /keys directory.

From there, each step in the OpenVPN HOWTO worked great for me. I'm still not sure why my terminal command . ./vars didn't work quite right.
