1. Introduction

1.1 Why I wrote this HOWTO

I work Real Networks, and we needed VPN service. This was my first real project, and I truly learned more about Linux with this than with any other task. I ended up using my experience with that project to write this document, to share with others what I learned, so that they can do ultra-nifty things with Linux too!

1.2 Acknowledgements and Thanks

I want to first and foremost thank my wife Julie, without her, I wouldn't be where I am today. I also want to thank Arpad Magosanyi, the author of the first VPN mini-howto and pty-redir, the utility that makes all of this possible. Jerry, Rod, Glen, Mark V., Mark W., and David, You guys rock! Thanks for all your help.

1.5 Document History

The original VPN mini-HOWTO was written by Arpad Magosanyi in 1997. He has since allowed me to take up the document and extend it into a full HOWTO. All of this would not be possible without his original document. Thanks again Arpad. :)

Version 1.0 of this HOWTO was completed on December 10, 1999.
