by Andrew Pam 07 Jan '16

07 Jan '16

We don't normally have a Beginners Meeting in January, but we've had an offer from an interstate presenter who wanted to practice his tutorial before presenting it again at the Linux Conference. Therefore we're delighted to be able to offer a bonus meeting which will make a great follow up to our last Beginners Meeting in November on nmap: Tutorial: Packets don't lie: how can you use tcpdump/tshark (wireshark) to prove your point. Start: Jan 30 2016 12:30 End: Jan 30 2016 16:30 Location: Infoxchange, 33 Elizabeth St. Richmond Link: http://luv.asn.au/meetings/map *Please note the new location for Beginners Meetings.* Sergey Guzenkov will look into: * differences between tshark and tcpdump, * tools that come with wireshark: dumpcap, capinfos, mergecap, tshark, * how to work with the capture files, * how to select the interface we want to capture on, * caveats in capturing (like vlans not being displayed), * capture and display filters, the difference between them, * statistics capabilities - this will be a big focus, * graphing, * decyphering SSL/TLS connection without access to server certificate. Most of the tutorial will be done on the command line without a GUI. Sergey is a full-type Linux sysadmin currently working in the Onegov of NSW Government. In the past he managed largest Australian Websites at News Limited, consulted big enterprises through Ecetera and Babel Consulting, and taught Red Hat Linux courses in Netherlands, London and Sweden.

LUV Main December 2015 Meeting: Maxima / holiday gifts
by Andrew Pam 26 Nov '15

26 Nov '15

Note: Suggestions and recommendations for Linux related holiday gifts are welcome, either via email or at the meeting. Start: Dec 1 2015 18:30 End: Dec 1 2015 20:30 Location: 6th Floor, 200 Victoria St. Carlton VIC 3053 Link: http://luv.asn.au/meetings/map Speakers: • Chelton Evans, Maxima • Andrew Pam, Holiday gift suggestions for Linux lovers Chelton Evans, Maxima Maxima is a popular copyleft CAS (Computer Algebra System) which can be used for both symbolic and numerical calculation. Chelton Evans will present a series of examples on Maxima's programming language from a pragmatic view (cheat sheet provided) to show how Maxima can be used: For example as a calculator, graph plotting, and solving a quadratic equation. He will offer an introduction to solving an equation f(x)=0 and why this is important. e.g. if a cannon fires - where does it hit? He will also provide an introduction to Newton's method for calculating the square root of two and a more complex solver, Newton's method with third order convergence, with an elementary discussion on numerical solvers and their merit. Chelton D. Evans is a teacher of systems administration (particularly Linux) and programming at RMIT's School of Life and Physical Sciences (SLAPS). His research interests have for the last five years been building a higher dimensional calculus of which the standard calculus is a projection, and a theory of sum and integral convergence at a point at infinity. Andrew Pam, Holiday gift suggestions for Linux lovers This seems like a good time of year to take a look at all the latest cool devices that run Linux. Andrew will also mention some of the latest games that run on Linux. Andrew Pam first discovered an interest in boolean logic when his mother carried him in her arms at just the right height to reach light switches as they passed through doorways. He was lucky enough to go to a school with an obsolete PDP/8e: switches, lights, core memory, paper tape, punched cards and all. He first started programming on a TRS-80 model 1 level I and the first computer he owned was a Commodore VIC-20. He has run the gaming Miniconference at linux.conf.au in the past and enjoys playing computer games on Linux systems. He is the current president of Linux Users of Victoria. 200 Victoria St. Carlton VIC 3053 (formerly the EPA building) Late arrivals, please call (0490) 049 589 for access to the venue. Before and/or after each meeting those who are interested are welcome to join other members for dinner. We are open to suggestions for a good place to eat near our venue. Maria's on Peel Street in North Melbourne is currently the most popular place to eat after meetings. LUV would like to acknowledge Red Hat for their help in obtaining the venue and VPAC for hosting.

LUV Beginners November Meeting: Security scanning with Nmap
by Andrew Pam 19 Nov '15

19 Nov '15

Start: Nov 21 2015 12:30 End: Nov 21 2015 16:30 Location: RMIT Building 91, 110 Victoria Street, Carlton South Link: http://luv.asn.au/meetings/map Scott Junner will offer a basic run through of the main functions of Nmap with some explanations of the background of what Nmap is doing and why it gets some of the results it gets. He will talk about why you would want to use Nmap and give an example of a few scans he did on his own network to show the kind of information that others could collect. Or you could collect on others - depending on which way you lean. Scott used to live in a world where Free and Open didn't really mean much more than being naked and promiscuous at festivals. Then he decided to try a little programming and his world changed forever. He loaded the Fedora OS onto his Macbook and hasn't looked back. But feeling the guilt of taking advantage of everyone else's hard work in the world of free software got to him, so he thought he should find a way to give back even though he's not really competent at writing useful software yet. Scott is now the Vice President of Free Software Melbourne and does his best to help other people who'd like freedom or just any old help with computers in general. He hopes one day to be a Network Admin, and perhaps write some code that some one else thinks is cool. He's helping his son build his first computer too. There will also be the usual casual hands-on workshop, Linux installation, configuration and assistance and advice. Bring your laptop if you need help with a particular issue.

He will also cover some of the history of SE Linux in terms of algorithms and design principles. This talk is about OS design and systems programming. There will be very little content about using SE Linux as that has been covered in other lectures. *Russell Coker* has been working on SE Linux since 2001. He writes most of the policy for Debian. He has done lots of other Linux development over the years, mostly involved with Debian development. ------------------------------------------------------------------------ Lev Lafayette, Parallel Programming Parallel programming is the implementation of simultaneous computation typically applied through either tasks or data. In this introduction the need, core concepts, potential problems, and implementations will be described and illustrated with multiple examples in R, Python, C, and Fortran. *Lev Lafayette* is a systems administrator at the Victorian Partnership for Advanced Computing. He has been a member of the Linux Users of Victoria committee for a very long time, collects postgraduate degrees, plays simulation and roleplaying games, and is known to annoy politicians with regularity. ------------------------------------------------------------------------ 200 Victoria St. Carlton VIC 3053 <https://www.google.com/maps/place/200+Victoria+St,+Carlton+VIC+3053,+Austra…> (formerly the EPA building) Before and/or after each meeting those who are interested are welcome to join other members for dinner.

LUV Beginners October Meeting: Mail server installation training
by Andrew Pam 11 Oct '15

11 Oct '15

Start: Oct 17 2015 12:30 End: Oct 17 2015 16:30 Location: RMIT Building 91, 110 Victoria Street, Carlton South Link: http://luv.asn.au/meetings/map This event is a hands-on lesson in installing a MTA (Mail Transfer Agent). It would be best to have a laptop, tablet, or phone with MUA (Mail User Agent) software installed. A basic knowledge of system administration is required. The work will probably be done in groups as it's likely that the number of people attending will exceed the number of virtual machines. Russell Coker has done lots of Linux development over the years, mostly involved with Debian. There will also be the usual casual hands-on workshop, Linux installation, configuration and assistance and advice. Bring your laptop if you need help with a particular issue.

LUV Main October 2015 Meeting: Networking Fundamentals / High Performance Open Source Storage
by Andrew Pam 23 Sep '15

23 Sep '15

http://luv.asn.au/2015/10/06 Start: Oct 6 2015 18:30 End: Oct 6 2015 20:30 Location: 6th Floor, 200 Victoria St. Carlton VIC 3053 Link: http://luv.asn.au/meetings/map Speakers: • Fraser McGlinn, Networking Fundamentals, Troubleshooting and Packet Analysis • Sam McLeod, High Performance, Open Source Storage Fraser McGlinn, Networking Fundamentals, Troubleshooting and Packet Analysis Let's be honest, the concept of networking seems like it is pretty simple and most of the time it "just works". But what is actually happening under the hood? How can we troubleshoot and identify the problem when things go wrong without feeling like we are working on some alien lifeform? This talk will focus on the basics of networking, the absolute fundamentals to any sort of connectivity. It will get deep into packet analysis using tools such as tcpdump and wireshark, help understand the underlying protocols and use this as a tool to troubleshoot some real life networking issues. Fraser McGlinn is a Network Engineer who has been working in the ISP industry for just shy of five years. Day to day, his role has varied from running a core MPLS network and provisioning new services to building and maintaining services such as Radius, DNS and NMS Monitoring. Fraser has been a Linux fan since a young age, and built his first Linux PC in 2007 running on old parts that he scraped together from the junk pile at the local computer recycler. It ran for a few years hosting web servers etc from under his bed. Sam McLeod, High Performance, Open Source Storage Sam McLeod has designed and implemented a purely solid-state, high performance modular storage system - that is completely configured and provisioned in code. Ops lead at InfoXchange and active DevOps community member, originally from Christchurch, New Zealand and now a Melbournite for four years Sam is driven by the idea of improving both the technology sector and the product delivery journey or as Larry Wall said "Easy things should be easy, and hard things should be possible". You can find him ranting on twitter under the user @s_mcleod or on his neglected blog: https://smcleod.net. He has also recently started an online DevOps community: https://zendevops.com. 200 Victoria St. Carlton VIC 3053 (formerly the EPA building) Before and/or after each meeting those who are interested are welcome to join other members for dinner.

Adjourned 2015 LUV Annual General Meeting
by Andrew Pam 12 Sep '15

12 Sep '15

Start: Sep 19 2015 15:30 End: Sep 19 2015 16:15 Location: Boardroom, Electron Workshop, 31 Arden Street, North Melbourne Link: http://www.electronworkshop.com.au/ Confirmation of adjourned LUV 2015 AGM This notice is to confirm that Linux Users of Victoria Inc. will be holding the adjournment of its Annual General Meeting, on Saturday 19th September 2015. The meeting will be held in the Boardroom of Electron Workshop at 3.30pm. The only business to be conducted at this adjourned meeting is that on the notice of the original AGM (to which you should refer), namely committee and financial reports, and election of the committee. Explanation: Under the new Model Rules, the original AGM, on 1 September, had to be adjourned because it did not reach quorum. If the adjourned meeting does not reach quorum within 30 minutes, then the members present (so long as there are at least three) can conduct the business as if a quorum were present. Note that the meeting is scheduled at this time and place for convenience, since we expect a number of LUV members to be attending the Software Freedom Day event anyway. However, keep in mind that this adjourned AGM is a separate LUV meeting, and is not part of the Software Freedom Day program. Electron Workshop is on the south side of Arden Street, about half way between Errol Street and Leveson Street. Public transport: 57 tram, nearest stop at corner of Errol and Queensberry Streets; 55 and 59 trams run a few blocks away along Flemington Road; 402 bus runs along Arden Street, but nearest stop is on Errol Street. On a Saturday afternoon, some car parking should be available on nearby streets. LUV would like to thank Electron Workshop for making their boardroom available for this meeting, also Red Hat for their help in obtaining the Trinity College venue and VPAC for hosting. Linux Users of Victoria Inc., is an incorporated association, registration number A0040056C.
