PLUG's August topics will be CLI packet forensics and Blender.
Topic: CLI packet forensics
As Information Security evolves, more tools are being released that allow us investigate incidents quicker and easier, conversely making many analyst lazier. The sacrifice we have made to this idol of convenience is increasing layers of abstraction from the 'truth' of raw data, placing trust in tools we did not write using methods we do not know. While these high level tools are good to have, the ability to use simple, low-level tools is essential for security professionals.
This workshop will focus on using 'low-level' tools for network forensics. We will be using Wireshark's CLI tools, tcpdump, and Linux CLI tools to look at PCAPs to find and extract interesting information. A laptop with an Ubuntu VM is recommended, as all the tools we will be using should be 'apt-get'able. Please install these tools before the workshop if at all possible.
Topic: Basic Modelling Tools in Blender 3D
Basic introduction to Blender, focusing on the modelling tools. The basic geometric techniques (extrusion, knife cut, radial cutting tool etc) along with the sculpting tools (and the dynamic topology sculpting tools). Then an example of how to use the boolean tools to create geometry as well. Finally a quick demonstration of what "UV unwrapping" is about, and how to utilize it.
Various hobbies include leatherwork, blacksmithing, wood work , archery (belongs to the Society for Creative Anachronism) and lately SCUBA. Was happily surprised to find out the Linux based software for his dive computer was written partly by Linus.

The inaugural Sierra Vista Ubuntu Hour was held from 1730-1830 on 24 July 2014 at the Sierra Vista Public Library foyer. There were four Arizona Loco team members in attendance, three of which drove from the Phoenix area to ensure the success of this inaugural event. Two people stopped by and expressed an interest in having Ubuntu installed on their computer. I will accomodate them this next week. A good time was had by all present before, during, and after the Ubuntu Hour.
