All meetings are cancelled until May

PLUG - Fri, 2020/03/13 - 04:54
We had already decided to cancel meetings for the rest of the month when we were informed that the room was going to be off limits until May because to the risk of public gatherings due to COVID-19.  That's a little longer that we had discussed cancelling things, but it's better to be safe than sorry, so until May there will be no meetings unless things change.

We will be back in May with some really good presentations that we already had lined up.

See you at the next meeting.   Stay healthy.

PLUG Topic for March 12th Space Night 2

PLUG - Sat, 2020/03/07 - 14:31
This month we'll be treated to PLUG's second Space themed night.

Space Night 2

Join PLUG for a space panel featuring members of the MASTCAM-Z team discussing the roles of Free Software and open standards in their projects and the open science they're investigating as part of their missions.

Based at ASU, the panel members have worked on projects such as the MASTCAM-Z and MASTCAM projects for Mars rovers, Lunar Reconnaissance Orbiter and the Psyche Mission.
Video from previous Space Night panel:


Ernest Cisneros

Ernest received a Bachelor's of Science in Geology, from the University of Texas at El Paso (1989). After a stint in graduate school at Northern Arizona University, studying the metamorphic history of the Old Woman Mountains, he began a 27 year career combining his love of geology and computers. Ernest has worked at the USGS in Flagstaff, Duke University, Northwestern University and most recently at Arizona State University. Ernest has supported science and data processing for Clementine, MSI on NEAR, CRISM on MRO, MDIS on MESSENGER, Pancam on MER. His most recent work was developing the Science Operations Center for the Lunar Reconnaissance Orbiter, supporting multispectral data processing of MASTCAM images from MSL, developing the ground data system for MASTCAM-Z instrument on the Mars 2020 rover, and developing the Science Data Center for the Psyche Mission. During his career, Ernest has seen Linux grow from "just something we are playing with for SysAdmin stuff" into a mainstay in server rooms, desktops and at home, tackling a wide-variety of roles. He has used a variety of Linux flavors: Slackware (installed from floppies), Redhat, Debian, CentOS, SuSE, and Ubuntu (most recently), installed on everything from SBC (Raspberry Pi and Tinkerboards), Intel/AMD PC's, PowerPC, RISC and a variety of other architectures.

Kristen Paris

Kristen is the Down-link Operations Lead for the Mastcam-Z camera for the Mars2020 rover mission and previously worked with the Lunar Reconnaissance Orbiter Camera also at ASU. Kristen has been using Linux-based systems for NASA Instrument Operations for over 10 years. Usually she uses her Linux-y powers for good, but sometimes her powers have other (unintended) consequences. Kristen automated myself out of a job and enjoyed it! She has also brought a 200+node computing cluster to a screeching halt (know if 3rd-party software is secretly trying to be "helpful" and know how to disable these "helpful" features). Kristen loves Space, enjoys computers (when they do what she intends for them to do), and considers herself a Danger Linux Power User.

Corrine Rojas

Corrine is a NASA Mars 2020 Rover Mastcam-Z Instrument Operations Engineer based at Arizona State University (ASU). She is a science team collaborator for the Mars Science Laboratory, formerly at the Lunar Reconnaissance Orbiter Camera. Her specialty is spacecraft operations (orbiters and rovers), research in planetary geology, and creating all kinds of maps, particularly 3D terrain maps that are out of this world. She has a BSc in Geography and Geographic Information Science from ASU. She was born and raised in Phoenix, AZ to loving immigrant parents from Durango, Mexico. In college, she was a Shirley G. Schmitz Foundation Scholar for entrepreneurs; participated in an ASU-funded start-up DemocraSeed in which she mentored high school-aged kids in a rural AZ town about creative problem solving issues in their community using design thinking; and interned at Jet Propulsion Laboratory for the Curiosity rover mission operations team. She is currently on the board of the Society of Women in Space Exploration, and on the leadership council of Latinas in Earth and Planetary Sciences (Geolatinas). She does not consider herself a technical computer science person, though she is slowly coming to terms that her job is 80% bash scripting to manipulate a ton of data, and you kinda have to have a good idea of what you’re doing in order to spare your perfectly obedient hardware from being smashed by a 2x4.

Nathan Cluff

Nathan is the Lead Systems Administrator for the Mastcam and Mastcam-Z cameras on the Mars Science Laboratory and Mars 2020 rovers in addition to supporting operations for various other missions such as the Luna Polar Hydrogen Mapper (LunaH-map) mission. Nathan has been involved in various Linux administrative positions for the last 18 years and has been in the School of Earth and Space Exploration at ASU for the last 4 years.

Topic for Security meeting on Feb 20th

PLUG - Tue, 2020/02/18 - 14:46

Donald ‘Mac’ McCarthy: Firewall Fundamentals and Network Segmentation with pfSense

This presentation will cover two fundamental steps in properly securing networks.

Firewalls are one of the most basic and universal network and security controls in a security engineer’s tool bag. We will cover some basic setup and rule creation with pfSense.

Network segmentation is critical for maximizing the effectiveness of security controls. We will discuss some strategies for segmenting networks, practical segmentation, segmentation challenges, and how to best deploy network controls within network segments.

About Mac:
Mac is a 17 year veteran of the IT industry. He has experience worked for organization ranging in size from 10 to 200,000+ employees. Mac has been involved in information security for the past 9 years with organizations in the academic, healthcare and financial, and public sectors. Mac is a linux enthusiast with a passion for using large compute clusters to help solve the most challenging problems in security analytics. He has given presentations globally on business email compromise and credentials stuffing. Mac currently serves as the Director of Field Operations for Open Source Context.

PLUG's 2019, End of the Year, Party

PLUG - Mon, 2019/12/09 - 12:18
It's December and time for our annual end of year pot luck.

Bring friends and family!!

It's a pot luck, so bring some food or drinks to share if you can. It's a holiday party, meaning we'll likely have tons of snacks and deserts. This presents an opportunity to bring a main course, salad or veggie side dish. Or, cupcakes or pie if you prefer :).

If you can't bring food, please still show up.

The meeting is in out regular location at The Desert Breeze Substation.

Since we're eating for the party, we will not go out to a restaurant afterwards.

No alcohol.

As always, we're on the 2nd Thursday of the month.

Also join us at our Linux/Free Software Stammtisch on the following Tuesday (Dec 17th) at 7pm. If you're looking for help with your resume; at next month's Stammtisch we will have a resume review night starting at 6pm.

The PLUG Security Meeting that would normally occur the week after the Holiday Party is canceled due to it happening too close to Christmas, but join us in January for a fresh new security meeting.
