GPS rollover event coming up - are your NTP servers ready?
by Adam Thompson 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

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. Look for signage once you're at the building, or ask a security guard. ******************************************************************* For more information about MUUG, and its monthly meetings, check out their web server: https://muug.ca/ Help us promote this month's meeting, by putting this poster up on your workplace bulletin board or other suitable public message board: https://muug.ca/meetings/MUUGmeeting.pdf -- Manitoba UNIX User Group E-mail: <gedetil(a)muug.ca> c/o Gilbert E.
