OpenVPN_2.0.9
The VPN topic will be of interest to all on the VUC so we’re inviting Markus Feilner, author of “Beginning OpenVPN 2.0.9“.

Two copies of this book to give away today

The following is from the preface of the book, co-authored by Norbert Graf:
OpenVPN is an outstanding piece of software that was invented by James Yonan in the year 2001 and has steadily been improved since then. No other VPN solution offers a comparable mixture of enterprise-level security, usability, and feature richness. We have been working with OpenVPN for many years now, and it has always proven to be the best solution. This book is intended to introduce OpenVPN software to network specialists and VPN newbies alike. OpenVPN works where most other solutions fail and exists on almost any platform. Thus, it is an ideal solution for problematic setups and an easy approach for the inexperienced.
On the other hand, the complexity of classic VPN solutions, especially IPsec, gives the impression that VPN technology in general is difficult and a topic only for very experienced (network and security) specialists. OpenVPN proves that this can be different, and this book aims to document that.
I want to provide both a concise description of OpenVPN’s features and an easy-to-understand introduction for the inexperienced. Though there may be many other possible ways to success in the scenarios described, the ones presented have been tested in many setups and have been selected for simplicity reasons.

IRC Transcript 2009-03-27

SIP hacking has escalated and there was a wave of it in recent times. John Todd published a simple common sense set of rules that are worth reading. One of the main risk areas is using user names and secrets that are too easy to guess (such as extension 200, username=2000,password=wakeme).

More on SIP for Skype etc. That looks like it will be an ongiung discussion. See the session with Michael Robertson above.

We briefly reviewed a new book called Asterisk Gateway Interface 1.4 and 1.6 Programming. John Todd and /me have both been looking at it and we both think it looks good. Since the discussion, I’ve read more of it and I will talk more about it in a future session.

We also mentioned AMOOCON where we can meet up for those of you who will be in Europe or are already there. I will be presenting two papers, one on VoicePHP and one on the VoIP community and various social networking tools.
