Zeek - from yesterday's meeting
by John Stoffel April 13, 2021

April 13, 2021

Guys, I'm looking into Zeek and unfortunately I don't have a second ethernet port on my main system, so it's not clear how I'd run a span port off my main switch to grab traffic. What hardware do people recommend for a zeek data collection node? I guess I could spin up my old WRAP board (http://www.pcengines.ch) which I used as my main router for years before I replaced it recently. But it's not super fast. It's got three 1gb ports, and 4gb of RAM with a 1Ghz single core AMD CPU. So it might do the job, esp since I can install Debian Buster on there without too much trouble. Sweet! John

Reminder! We've got a meeting this Thursday (April 8th, 2021!)
by Tim Keller April 5, 2021

April 5, 2021

Hey Everybody, This is a reminder that we have a meeting on April 8th, 2021. Same bat time, same bat channel Date: April 8th, 2021 7pm: Jitsi @ https://meet.jit.si/WlugMA Topic: As of yet, there's no topic for the meeting, however, there's a ton to talk about none the less! The PHP git server hack, the OpenSSL vulnerabilities, turns out the spectre mitigations can be mitigated? I'm sure more stuff will come up as well.. As usual drinks and refreshments aren't being provided as this is a virtual meeting.. But soon.. so soon I hope we'll all be able to get together safely. Thanks for being patient and coming to the meetings, I appreciate it. Tim.

WLUG history
by Anderson, Charles R March 13, 2021

March 13, 2021

Not sure we are the oldest, but we /might/ be the oldest still in operation. Is GNHLUG still in operation? If so, they are probably older. I was inspired to dig into my archives: An early email from our founder, Andy Stewart: ---------------------------------------------------------------------- Date: Sat, 26 Jul 1997 22:22:18 -0400 From: Andy Stewart <astewart(a)world.std.com> To: "Worcester Linux Users' Group" <wlug(a)mass-pc.wpi.edu> Subject: [Fwd: Caldera Inc. IT Forum] OK, gang, tell the man what you think! Remember, he is the gentleman who graciously donated the tee shirts and CDROM discs from Caldera... Andy ---------------------- Date: Wed, 23 Jul 1997 12:30:22 -0600 From: Paul La Fluer <paull(a)caldera.com> Organization: Caldera, Inc. To: astewart(a)world.std.com Subject: Caldera Inc. IT Forum Hello Andy, I hope everything is going good. I am in the process of organizing a conference while in New York. My goal is to rent out a large ballroom in a hotel and have all the usergroups in the area come and listen to Bryan Sparks our CEO and other talk about Linux and OpenLinux. There will be presentations plus a Q&A session. I would like to hear your feedback on the idea and if your group would attend. We would be giving away door prizes like OpenLinux Base and Standard and handing out t-shirts, papers and OpenLinux Lite and OpenDOS to all that attend. Please give me some feedback on this idea. I need to know soon to get things set up. Thanks, Paul La Fleur ---------------------------------------------------------------------- An email about our SECOND meeting (that refers to the first meeting): ---------------------------------------------------------------------- Date: Mon, 04 Aug 1997 21:29:13 -0400 From: Andy Stewart <astewart(a)world.std.com> To: "Worcester Linux Users' Group" <wlug(a)mass-pc.wpi.edu> Subject: Next WLUG meeting The next scheduled meeting for the Worcester Linux Users' Group (WLUG) is August 21, 1997, at 7 PM in the Gordon Library on the Worcester Polytechnic Institute (WPI) campus in Worcester, MA. We had a great turnout of about 20 people at our very first meeting last month - I hope to see all of you come back, and I'd like to extend a welcome to anybody who would like to attend. I would suggest parking in the "lower library" parking lot and hiking up the 102 stairs to the library (not to mention the 12 or so more stairs in the library to get to the 2nd floor!). For more information, feel free to send me E-mail at: astewart(a)world.std.com Look for the penguin signs! Hope to see you there! Andy Stewart WLUG ---------------------------------------------------------------------- I'd guess our first meeting was about July 23 or 24, 1997, or perhaps the week before, July 16 or 17. But maddog from GNHLUG forwarded this, which says "as always, the meeting are free..." which implies that July 30th is NOT their first meeting. If they had monthly meetings, that would place their first meeting in June 1997 or before. ---------------------------------------------------------------------- Date: Mon, 21 Jul 97 10:28:09 -0400 From: "Jon 'maddog' Hall, USG Senior Leader" <hall(a)zk3.dec.com> To: gnhlug(a)zk3.dec.com Subject: GNHLUG - Linux Cluster meeting July 30th at Martha's Exchange Hi, We now have a venue for the July 30th meeting of the GNHLUG, with Loki, a cluster of 16 Pentium PRO 200s, running Linux as the topic of the talk. We will be meeting on the *second* floor dining room of the Martha's Exchange Building in beautiful downtown Nashua. I will be picking up the speaker in Cambridge that day and transporting him to Martha's for dinner, arriving about 1730 hours. For those of you who wish to join us for dinner, please RSVP. The meeting itself will start at 1900 hours, with the speaker probably getting up steam about 1915 hours. As always, the meetings are free and open to everyone, and as a FINAL enticement I will be handling out *free* CD ROMS with the V1.2 Debian release for Intel on it. M. Patrick Goda, a principal of the Loki ( http://loki-www.lanl.gov/ ) project at the Theoretical Division of the Los Alamos National Labs, a Beowulf ( http://cesdis.gsfc.nasa.gov/linux-web/beowulf/beowulf.html ) style computer will be our speaker. I have convinced him to present a talk on the Loki project, one of linking together 16 Intel Pentium Pro machines to create a system that has: o high reliability o high throughput and generally 16-node IBM SP2 performance (over 1.2 GigaFlops) at 1/20th the cost (about $60K)!! Pat is a friend of mine that I introduced to Red Hat Linux when he was a graduate student at the University of Hawaii (long story). Due to the fact that Patrick is a rare find, I will invite the Boston Linux User's Group and the Worcester Linux User's group to join us that night, so I have arranged for larger quarters. Some additional Beowulf pages are from my own alma mater: http://einstein.drexel.edu/beowulf/Beowulf_concept.html including exerpts from the original Beowulf story: http://einstein.drexel.edu/beowulf/original_beowulf.html Warmest regards, maddog ---------------------------------------------------------------------- Nevermind, GNHLUG is definitely older by several years according to their web page: http://wiki.gnhlug.org/twiki2/bin/view/Www/PastEvents 1996 When Where What Who How Many 31 Jan 1996 UNH Durham Linux Linus Torvalds 200+ 1994 When Where What Who How Many 19 Oct UNH (?)

Linux video edit SW : OpenShot is cool ! and.... AppImages
by Doug Mildram Feb. 28, 2021

Feb. 28, 2021

doug> Pardon my non-meeting-attendance all but 1? month since 2020...anyways, (new fun thing or things I got to learn, below) Mostly this email is a Fun/FYI, but I suspect OpenShot could be popular and maybe some of you use it,etc and maybe even one/some of you are dabbling,etc at video editing. Myself, barely so far. TMI Since a friend (for sister's anniversary) wanted to create a slideshow+music ( MP4, say ) I discovered how easy that is on Linux lately (googling offers ~10 or Top Ten choices of SW). And since I put linux on this friend's desktop, it's a great match and way to teach/learn. (gawd, these life-story-in-pictures quests sure can make a camera-bound picture owner/taker have to cope w their mess of jpegs in cellphone) DRUM ROLL: I only tried one offering for video editing, and scored. .......................chose one that some review(s?) said is most user friendly. It (OpenShot) seems great, for my too-simple needs (slideshow of static pics, adding music/mp3) and can obviously do so much more. Output and input choices have huge lists (eg AVI,MP4 variants,etc for output..... you generate/export to). SO ANOTHER THING i learned doing this is: There's a release/package thing I wasnt aware of ... ....seems a too-easy alternate, in favor of pkgs/release-dependent installs/updates. IT IS CALLED an App Image and it really appears to me to be THIS SIMPLE: a) You download one big file, eg for OpenShot a 130-140mb one-executable file that they name OpenShot-v2.5.1-x86_64.AppImage , you can get from https://www.openshot.org/download/ .....which says......... b) AppImage requires no installation. Just download, make executable, and run. doug> Correct, it doesn't unzip anything, and the one executable "fits all". Wow! I will admit that (on my Mint desktop) the first time I run it (as me/plain-user), the GUI intro/setup dialog/window does ask me Yes/No ? for some question about creating something for?on? the Desktop, and I said YES and I did not get anything added to my ~/Desktop. But who cares? More fun anyways to launch it from a terminal and watch the stdout as you run the GUI. p.s. it DOES save PROJECT (not output/export result, but your per-video project setups) in your linux homedir under ~/.openshot_qt/ ...mine looks like: doug0@host:IN_MY_HOMEDIR:~$ ll .openshot_qt/ drwxrwxr-x 2 doug0 doug0 4096 Feb 27 14:23 transitions drwxrwxr-x 2 doug0 doug0 4096 Feb 27 14:23 profiles drwxrwxr-x 2 doug0 doug0 4096 Feb 27 14:23 preview-cache drwxrwxr-x 2 doug0 doug0 4096 Feb 27 14:23 presets drwxrwxr-x 2 doug0 doug0 4096 Feb 27 14:23 assets drwxrwxr-x 2 doug0 doug0 4096 Feb 27 15:17 cache -rw-rw-r-- 1 doug0 doug0 1453 Feb 27 15:57 libopenshot.log drwxrwxr-x 2 doug0 doug0 4096 Feb 27 15:57 title drwxrwxr-x 2 doug0 doug0 4096 Feb 27 15:57 thumbnail drwxrwxr-x 2 doug0 doug0 4096 Feb 27 15:57 blender drwxr-xr-x 30 doug0 doug0 4096 Feb 28 10:15 .. drwxrwxr-x 2 doug0 doug0 4096 Feb 28 10:39 recovery drwxrwxr-x 12 doug0 doug0 4096 Feb 28 10:43 . -rw-rw-r-- 1 doug0 doug0 17352 Feb 28 10:43 openshot.settings -rw-rw-r-- 1 doug0 doug0 1774732 Feb 28 10:43 openshot-qt.log Around 4mb of setup for (so far my only) 66mb MP4 mini-video of PICS w/ 6min of music, the MP4 I exported elsewhere.

Reminder! Virtual Meeting Tonight!! 7PM via Jitsi!
by Tim Keller Feb. 19, 2021

Feb. 19, 2021

Hey Gang, We've got a meeting tonight at 7PM! Location: Our usual Jitsu haunt: https://meet.jit.si/WlugMA Topic: I think the Itanium thing got beat to death, but we can still talk about it. Apparently there's still a pa-risc port of linux kicking around? Now I want to run it as a VM! Daryl McBride (SCO asshole) just fired for Chapter 13 so we can laugh at his expense. I'm sure there'll be some 3d printer talk, some Pi PICO chatter, plus whatever else. Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Hey Everybody, We've got a meeting next week on the 11th at our same time (7pm) As for a topic, if somebody would like to present something, I'd be up for it. I figure we'd all toast the depreciation of Itanium in the linux kernel. Good riddance! We'll definitely be talking about the PI4 Nano!! As usual, I'm sure other topics will organically surface. Location: Our usual Jitsu haunt: https://meet.jit.si/WlugMA Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

I don't want to join the endian wars. So I'll comment on something else. Stratus did not support Itanium because they follow rather than lead the market. When a replacement for PA-RISC was considered at Stratus we did look at Itanium. I recall studying the FW then called "EFI" around 2003 when I was in the VOS group. For the in-house VOS OS, Stratus would need compilers for PL/I and C and a modified linker to get to Itanium. Stratus never made this investment. What the VOS group did was to port to x86. Today VOS is still a 32-bit OS that runs on Motorola 68K, i860, PA-RISC and x86. This is unlikely to ever change for VOS as the compiler and linker tech leads have left Stratus. For the other three OS's supported by Stratus, Windows, Linux, VMware ESX, outsiders, not Stratus, would or would not be porting their OS to Itanium. (As was the case for amd64). Since the Stratus value add is to take applications coded to run on commodity HW and make the apps highly reliable by running on Stratus HW, Stratus would not move to Itanium until the customers already were developing to that platform. -- One more comment on a different topic: > >I personally play around with ATTiny85 and ATTiny84 MCUs when I get a >chance. Slowly looking at STM8 and STM32 stuff as well. And of >course the Arduino AVR stuff. > Me too, but somewhat bigger/faster MCUs.

Disk mirroring in Linux -- MD-RAID or LVM? Advantages and disadvantages?
by Michael Voorhis Jan. 23, 2021

Jan. 23, 2021

Hi all; In Linux I can do software RAID using LVM or with MD (i.e., mdadm) as a basis. I'm currently thinking of a simple mirror of two conventional SATA disks. The machine is being built to do a compute-workload involving examination of many small(ish?) files, and will not be a desktop or a recreational/gaming machine. I don't know anything about the files or how they'll be examined. How would YOU setup a simple mirror in whatever Linux you use? Why do you prefer your selection? Thanks, --MCV.
