Few days ago the OISF development team has announced the Suricata 1.0.4 release, a large number of (potential) issues have been fixed along with the update of LibHTP to version 0.2.6.

Fixes

- LibHTP updated to 0.2.6

On Wednesday, me and my wife we climbed to Medvednica mountain to attend the longest lunar eclipse in more than a decade. After a short ride we reach what we thought was the perfect spot to see the eclipse, several other folks had the same idea and the place was crowded. Luckily the sky was clear and we could see the wonderful spectacle of the full covered “bloody red moon”. After a while I decided to take a few shots of Zagreb city with the mysterious moon on top of it, shooting outside in the  dark  isn’t that easy, after dealing with the correct exposure and focus a few pictures come out good. As soon as we got back home, I decided to send the photo of the “city with the moon” to space.com, they were so kind to publish it on the dedicate Total Lunar Eclipse of June 15, 2011 photo album.

Croatian newspapers covered the publication of my photo on space.com, I was really surprised about and didn’t expect it at all. Looking forward to the next cosmic event.

Recently I’ve been contacted by Packt publishing about to review their new published OpenVPN 2 Cookbook. I was particularly pleased to be chosen by my previous contributions on OpenVPN, this made me feel confident to review  this book. OpenVPN is a Virtual Private Networking (VPN) software. Is one of the best Cross-platform examples in term of deployment variety, usually installed on Unix/Linux as server can inter-operate with many different operating system such Mac OS, Windows and Linux. OpenVPN come handy when you have to deploy VPN solutions in a heterogeneous environment, you will save a lot of headache.

OpenVPN 2 Cookbook is divided into twelve chapters that contains around 100 recipes to deploy and configure your optimal vpn solution, from Point-to-Point, Client-server IP-only and  Two-factor Authentication with hardware token. Covering most of the uses of OpenVPN this book is an invaluable resource for who want to evaluate and develop a VPN solution from a simple home network to a secure and redundant corporate  infrastructure.

I really enjoyed reading this book, because goes straight to the point of building stuff, skipping long and sometime useless introductions.

Table of contents

Chapter 2: Client-server IP-only Networks
Chapter 3: Client-server Ethernet-style Networks
Chapter 4: PKI, Certificates, and OpenSSL
Chapter 5: Two-factor Authentication with PKCS#11
Chapter 6: Scripting and Plugins
Chapter 7: Troubleshooting OpenVPN: Configurations
Chapter 8: Troubleshooting OpenVPN: Routing

Chapter 10: OS Integration
Chapter 11: Advanced Configuration
Chapter 12: New Features of OpenVPN 2.1 and 2.2

For me, it still remain unknown why spontaneous and unpredictable things work better than the ones long time planned, this is why a good pizza and a fresh beer along with great people can make the day. Hopefully this will be the first of many “Eat with awesome People” gatherings, if you want to join us for the next round, stay tuned!
