My third Book: Beginning OpenVPN 2.0.9

May 29, 2010

It’s been already some months since Packt published my newest “oeuvre”! During the last year, despite some minor organ transplantation :-),  I managed to update my OpenVPN book – and together with Norbert Graf I added lots of information about new features, setups and details of the recent releases of the world’s best open source VPN software.

Beginning OpenVPN 2.0.9

The book covers all the cool features of the latest OpenVPN versions, including 2.1, 2.1.1 and all older versions, too. Topics like high availability, mobility, management interfaces and more are included now.

The book starts off with a in-deep introduction to VPNs, OpenVPN and its various installations on different platforms. A long, detailed section deals with the numeruous configuration options, followed by many examples for advanced setups. X.509 certificates and PKI key management make another big part of the book, followed by mobility, troubleshooting and firewalling.

Update: I found some minor mistakes in the book, mostly typos. Please read it and send any enhancement or hint, however small to my email address. Thanks a lot for any feedback that makes this book even better, and thanks a lot to all those thousands who bought the first edition during the last three years!
