Job opportunity on my team.
by Sean Cody 13 Nov '18

13 Nov '18

Hey there, we're looking to find more folks for our team. Specifically security focused 'infrastructure specialists' to build and deploy security services at 'enterprise' scale. We are growing the practice as well as tackling some very unique challenges so this is a great time to try something different or suffer my presence on a more frequent basis. This kind of thing doesn't come up often and we'd very much like to get the word out there for local folks (security talent isn't just limited to Toronto and Vancouver). As a technical lead in this role, I'd be happy to field any questions and if you'd like to hear more about the role please get in touch. https://gwlcareers-greatwestlife.icims.com/jobs/16036/senior-security-engin… https://www.linkedin.com/feed/update/urn:li:activity:6467883747298598912 Please forward this along to anyone you think would be interested, despite my graylisting (consider it a test) I definitely would like to hear from you! -- Sean P.S.

MUUG Meeting, Nov 13, 7:30pm -- Captive Portal, RTFM: date
by Gilbert E. Detillieux 06 Nov '18

06 Nov '18

The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, November 13. The meeting topic for this month is as follows: Build an IP Captive Portal from Scratch (For Fun and Education, but Not for Profit) Love 'em or hate 'em, captive portals are widely used to restrict Internet access to authorized users. What if you need to set one up, but all the "canned" solutions aren't quite right for your use case? This presentation by Gilbert Detillieux will show you the various components that make up a captive portal, and how you can set one up from scratch, using Linux Netfilter/iptables, the Apache web server, ISC DHCPD and BIND, and some custom back-end scripting. RTFM: date The lowly date(1) command has been a fixture of UNIX systems from the very early days. Yet there may be features in this command that would surprise you. Adam Thompson will present this RTFM. The group holds its meetings at 7:30pm on the second Tuesday of every month from September to June. (There are no meetings in July and August.) Meetings are open to the general public; you don't have to be a MUUG member to attend. ******************************************************************* Please note our new meeting location for this month: *Room 1M28* Manitoba Hall, University of Winnipeg, entrance on Ellice Ave. between Spence and Balmoral St. Parking is available on the surrounding streets and in the lots on nearby streets.

setting up RAID 1 with mdadm
by Gilles Detillieux 18 Oct '18

18 Oct '18

Circumstances finally forced me to bite the bullet and learn something I had been putting off for too long: setting up a RAID array under Linux. I'm almost embarrassed, now that I've done it, that I waited so long because it was way simpler than I'd imagined. I thought I'd have to figure out all kinds of magic with LVM, parted, and mdadm, but I found this tutorial that showed a simple set of mdadm commands to set up RAID 1: https://www.digitalocean.com/community/tutorials/how-to-create-raid-arrays-… This was actually one of the simplest scenarios: the system had an SSD for the root/boot partition, and two 2 TB hard drives for data storage (/dev/sdb & sdc), so I just needed to set up RAID 1 and not worry about the intricacies of booting from RAID. So, software RAID seemed like the quick & easy way to go with a minimum of fuss. Now the nagging question: is it really this simple, or does the tutorial above oversimplify and omit some important steps? Can someone with ample RAID and mdadm experience advise or provide tips on anything else I should do or lookout for? Thanks, Gilles -- Gilles R.

MUUG Meeting, Oct 9, 7:30pm -- Reproducible Builds, RTFM: netcat
by Gilbert E. Detillieux 02 Oct '18

02 Oct '18

The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, October 9. The meeting topic for this month is as follows: Reproducible Builds Many of us run some amount of Free and/or Open Source Software, but how can we ever be sure that what we're actually running was built from the allegedly published source code? Whilst not a complete security solution in and of itself, find out how this project helps influence and improve security and development as part of a wider set of policies. Presented by Muz. RTFM: netcat, with Wyatt Zacharias A look into a computer networking utility for reading from and writing to network connections using TCP/IP protocol, designed to be a reliable "back-end" tool that can be used directly or easily driven by other programs and scripts. The group holds its meetings at 7:30pm on the second Tuesday of every month from September to June. (There are no meetings in July and August.) Meetings are open to the general public; you don't have to be a MUUG member to attend. ******************************************************************* Please note our new meeting location for this month: *Room 1M28* Manitoba Hall, University of Winnipeg, entrance on Ellice Ave. between Spence and Balmoral St. Parking is available on the surrounding streets and in the lots on nearby streets.

GPS rollover event coming up - are your NTP servers ready?
by Adam Thompson 20 Sep '18

20 Sep '18

So I just became aware of this… https://spectracom.com/resources/blog/lisa-perdue/2018/gps-2019-week-rollov… � Bottom line: on April 6th, 2019, your GPS receiver might start spitting out the wrong time. It’s a Y2K-style problem, the article describes the details. Make sure your firmware is updated and will handle this even properly, and/or your NTP software will correctly compensate for the crazy time the GPS receiver will start spitting out. � -Adam

JBOD card recommendations?
by Wyatt Zacharias 15 Sep '18

15 Sep '18

Anyone have recommendations on a model of JBOD SAS/SATA card to add to a Linux based NAS? Not looking for any hardware RAID capabilities, but if it's a RAID card with JBOD mode that's fine too. Also needs to have internal connectors as they're all internal drives. -- Wyatt Zacharias

MUUG Meeting, Sept 11, 7:30pm -- Ansible, RTFM: tcpdump
by Gilbert E. Detillieux 04 Sep '18

04 Sep '18

The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, September 11. The meeting topic for this month is as follows: Managing Systems with Ansible Ansible is an OSS IT automation engine, in the vein of Chef and Puppet. But what exactly can you do with it? John Gunkel will be filling us in. He'll be covering key concepts, package management, templates, roles, GUI interfaces, and more! A demo will bring it all together. RTFM: tcpdump(1) with Adam Thompson Debugging an application's behaviour is sometimes easier to do by looking at the interactions it has with other systems on the network than by examining the application itself. Modern UNIXes all come with a tool, tcpdump(1), that can examine, filter, decode, and log all the traffic seen at a network interface - whether it originates on that system or not. Adam will discuss the most common options for [12]tcpdump(1), and hopefully demonstrate a simple example. The group holds its meetings at 7:30pm on the second Tuesday of every month from September to June. (There are no meetings in July and August.) Meetings are open to the general public; you don't have to be a MUUG member to attend. ******************************************************************* Please note our new meeting location for this month: *Room 1M28* Manitoba Hall, University of Winnipeg, entrance on Ellice Ave. between Spence and Balmoral St. Parking is available on the surrounding streets and in the lots on nearby streets.
