Re: cool HW-info linux/bsd tool "inxi"

I noticed that the fan speed was zero. I had the same result on mt Mint machine. To fix this I had to run sensors-detect (part of lm sensors?) to update /etc/modules with the correct driver(s) and reboot. Hopefully, GKrellM or ones preferred hardware monitoring GUI will work with fan speed now. Just adding my 2 cents worth.

That is pretty nifty, thanks. It's such a PITA trying to pull all that info when I want to inventory systems, this does a lot! I can also imagine it would be a pretty useful tool for nefarious types fishing around for hardware to steal.

Dec. WLUG meeting reminder! Topic: DMARC, SPF and DKIM

by Tim Keller

Hey Everybody! We've got a meeting tomorrow! Date & Time: December 13th 2018 @ 7PM Location: WPI Student Center Mid Century Room (rm 331) Presenter: Frank Sweetser Topic: DMARC, SPF and DKIM. This topic came up on the list as a possible reason why some people weren't seeing all the mail on the list and I thought it might be an interesting topic. The good old days of the internet are sadly dead. Now that the Nigerian princes have given up trying to distribute their money, we're instead left with more sophisticated attacks. DMARC, SPF and DKIM are a few of the techniques now being employed to help cut down on spoofed email. As usual refreshments and snacks will be provided and afterwards we'll head off from dinner and keep the conversation going. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Keith, I can definitely give you a ride. I just don't remember your address.

Thanks for the support and keeping the list alive. Perhaps too alive (I can rant/ramble!) Are Gigabyte motherboards OK? I've only had one so far. Now dying perhaps. Looking ahead..... since I upgrade "combo style" (all ram and cpu attached/included) I'm gonna look at (days from now) a used motherboard+cpu+ram+beast video+beast fan, hope it fits under my hood, dude speaks well about his retired GIGABYTE GA-870A-UD3 SKT.AM3 AMD870+SB850 4XDDR3-1866, IEEE1394 USB3, SATA3, RAID, ATX plus cpu,ram, and even fan info on this BEAST of a fan, should i be scared? https://www.amazon.com/Noctua-NH-U9B-SE2-CPU-Cooler/dp/B002VT1GZ6 doug> I find it cool that a machine/mb that old, is still way more than I need. I've only got one HD/disk for example. I'll try to buy her a tiny computer NEW someday if my new/old cheap-out fails. I want less power! Good brakes please! Ballpark of $100+ for the combo you CAN still find online if you dare and you get lucky that it really works for you. ...below, tangent about the seller i will meet this weekend.

Frank!*** Why does one message say From: cra(a)wpi.edu, and the other From: wlug(a)lists.wlug.org? (Nervermind, CRA explained that.) I don't want to try to prevent anyone from talking about anything, but I don't have much to say about that. I would have wrote you a letter, but I couldn't spell PHLTT!! If Frank does not have a presentation, I could commit by Thursday to make some slides and bring a laptop. I tested slide-showing a few months ago with the WPI cable in the Mid-century Room and it worked. Here's the catch: My usual ride is unavailable that day. I don't drive and I have not been walking well. I used to walk to WLUG; I fell on the hill. No problem; I got up and went on; it happens. I don't want to be carrying heavy and fragile equipment. I tried to go for a walk this morning, but fell and skinned my knee at the end of my own driveway. If someone could commit to pick me up at my house about 1/2 hour before the meeting I would make sure I was ready enough to fake it. I live about a mile from WPI. Send me mail. I will show you some of what I have been doing, and how I do it. The title of my talk: Love Programs work better than Love Poems Computatational Metaphysics Why and how to write soutce code that can be read Or something else if I thnk of it. Someone said recently that one of the best talks ever was Doug Waud showing TeX printing stuff nobody understood. I thought: "I could do that". I am not a pharmacist, so I will dazzle you with Scheme programs and Algebraic Geometry run through LaTeX. All in living black and white (or glowing green). -- Keith

Yes. If you did not see Tim's announcement of the same, then something is wrong. Which leads me to my proposal, which I will put in another message so that it is not lost at the bottom. -- Keith PS: While I was writing this, two new messages came to me from wlug, one appears to be a copy of Doug Mildram's message dated 2018-12-09 the other a reply to that.

mailing list issues

by Anderson, Charles R

Some people (including myself) have not been receiving emails sent to the list. I'm guessing that DMARC may be blocking messages from senders' domains that have DMARC set up, so I made a MailMan change to enable DMARC Mitigations. This works by replacing your "From: you(a)wherever.com" with "From: Your Full Name via WLUG <wlug(a)lists.wlug.org>". Your original From: appears in the Reply-To: header. I'm also sending this message to test delivery to a few domains like yahoo.com and gmail.com.

If it is 4.19.x, you may have have hit a data corruption bug in Linux's block layer: https://www.phoronix.com/scan.php?page=news_item&px=Linux-4.19-EXT4-Issue-L… My suggestion--rollback to 4.18.x until this is all resolved.

desktop (linux Mint/ubuntu) Motherboard/sata/grub fun

by Doug Mildram

Warning: there's a couple "fun" ( aka "new to me") things in this LONG email. SUMMARY 2-lines-below: 1) on reboot, an initramfs prompt, errors only seen briefly as boot screen overwrites it. Needed fsck. 2) later when things got worse, my solution followed by a different error message re: "environment block too small". the LONG story: Months ago i managed to move wife/maureen's desktop environment to Mint(ubuntu underneath). Usage: firefox,gmail (almost nothing else of note. This took some persuading, but desktops are such a fallback these days......another topic for another day) DESKTOP: 10?yr-old Gigabyte motherboard with sata2/sataII ... 4 ports. I only use 1 sata port. I "gave" it a $90/bestbuy 256g SSD Samsung months ago for /dev/sda which ran well+fast of course, turns out the SSD is actually still fine internally. A FEW WEEKS AGO, the "hint" symptom (1 of 2 in this long story) for disk woes was.... ( it started crashing occasionally, then) ON BOOT, it would sometimes STOP at this prompt initramfs> and with good eyes as the boot-attempt screen(s) would fly by and return to above prompt, I discovered I could fix it with ( actually i did not use the "-y" prompt, but it's the same fix either way) initramfs> fsck -y /dev/sda1 Which worked every time (a few times), nothing scary for an ex-unix-sysadmin, followed by initramfs> exit ######## would allow it to boot and be OK for days or so. I taped THAT magic (fsck...) onto a paper mini-sign on the PC for another rainy day. TODAY, the crash was followed by not booting (random results, kernel panics or bios/grub waiting). So I brought the SSD to my other living room desktop (not booting FROM it...) checked SSD with sudo smartcl -a /dev/sda #### AND ITS FINE. I moved the SSD "back" to wife's PC on another SATA port. It's fine! (motherboard deteriorating i guess....but might last another decade). I did run into.... ("created" by moving the disk i assume) .... a boot/warning error NEW TO ME: On initial boot a WARNING ERROR on the early/black screen (similar to where initramfs> shows up..just before that i think) "warning: environment block too small" was actually ignorable (after a few secs, boot marched on to kernel/logo). But I found "it's a thing" and the error appears solvable with first google hit suggesting linux user# sudo rm /boot/grub/grubenv # or "mv" it somewhere.old; 1024 byte file. ...............# sudo grub-editenv /boot/grub/grubenv create and reboot. Seems good now except (new i think; probably from the sata port move?) there's a ONE MINUTE wait on the initial boot with the Mint logo flashing. Final things-to-inspect: (no need to "fix" /etc/fstab which of course does find the disk parts ( just / and swap) by UUID and /var/log/syslog ( I have exportedthe old history to study, i think the disk errors stopped. ) =========================WRAPUP Haven't solved this learn-all mission yet, but...hope to make it to WLUG THURS EVE and i just thought of a (this) topic. Trick is knowing where to start such a story/tutorial; I'd try to skip over BIOS and sata/disk/etc basics, the fuzzy parts for me involve "initramfs" ... grub ..... and maybe that's it for me.

OpenGameArt Movie Video Game

by Dennis Payne

Normally I do National Novel Writing Month in November. This year I decided to try the Indie Game Making Contest 2018. I spent the month working in my free time on a new computer game. I had thought of this game a while ago (including doing a novelization of it for NaNoWriMo last year). The idea was to use lots of art from OpenGameArt.org. Since the styles of the artwork can be drastically different, that was integrated into the story. The villain is in the Liberated Pixel Cup style. (It was a contest opengameart.org did to create lot of artwork which could be used together.) He would be trying to wipe out all the other art styles. (It's a crazy mashup like the Lego Movie.) The game didn't get to the level of completion I had hoped. I posted a Postmortem on the project: http://identicalsoftware.com/games/opengameartmovie You download the Windows version of the game from: https://dulsi.itch.io/opengameart-movie-video-game Unfortunately there isn't a log of content in the game as much of the work was building the game engine. (Why isn't there a Linux download? I was rushing to post it before the contest end and didn't get around to posting a Linux build. We aren't allowed to put up new downloads while the judging is being done.) -- Dennis Payne <dulsi(a)identicalsoftware.com>

Frantic last minute room change

by thinkbrown＠gmail.com

Hey WLUG! Frantic last minute change of room. Due to the relative inaccessibility of Stratton after 5PM, we moved to Campus Center room 128 (the Taylor Room). This is on the first floor (down the stairs through the main entrance). Sorry for the last minute notice Logan (pretending to be Tim)

Reminder! WLUG Meeting NEXT week! Nov. 8th, 2018! NOTE: LOCATION CHANGE!

by Tim Keller

Hey Gang! We've got a meeting next week! Date and Time: Nov. 8th, 2018 @ 7pm Location: *Stratton Hall Room 309* Topic: GNURadio / Software Defined Radio / GQRX Presenter: Ian Gelman Here's what Ian had to say about his presentation... I'd like to throw my hat in the ring and give an overview+demo of GNURadio, a FOSS package for graphically developing DSP applications and interfacing with Software-Defined Radios (SDR). I spent last summer at MITRE using this software heavily, and I'm also using it for my MQP work. For the demo, I'd like to bring down some hardware from my lab ( https://www.ettus.com/product/details/UN210-KIT) as well as the $20 RTL-SDR dongle ( http://www.nooelec.com/store/sdr/sdr-receivers/nesdr-mini-rtl2832-r820t.html) to show reception of broadcast FM, ADS-B telemetry from airplanes, as well as some real time views of Wi-Fi, Bluetooth, and streaming drone footage from a DJI Phantom 3 Pro. Here's the outline: What's SDR? Why should we care? Why do I care? Who uses GNURadio? GNURadio fundamentals Introducing the workflow/flowgraph interface Cloning/Building/Installing (this won't be specific, just mentioning the GitHub repo and where the quickstart guide is) How to contribute (also GR-hackfest!) GNURadio as a software development framework Ex: GQRX (http://gqrx.dk) For the demo, I'll show off some stuff I've made with GNURadio, as well as GQRX to interface with the RTL-SDR. I'm pretty confident that I can cram it inside of 2 hours, because I'll be basically recycling the slides I made for my MITRE presentation, minus the branding and project-specific content. As usual, drinks and snacks will be provided and we'll head out to dinner afterwards. NOTE: I will be unable to attend this meeting. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Re: Too bad about redhat...

by Tim Keller

I guess the question I have is this. IBM just spend 34B on redhat. Okay, now what. Is it possible that RedHat's support stuff was generating so much revenue that IBM thinks it can simply sit back and let it print money? While that's possible, I don't think RedHat has made 34B in it's entire existence. Thusly, there will be a point where the people who push the heaps of money around at IBM go "You know, we spent 34B on this thing, how are we going to get some ROI out of this?" My interactions with AIX and it's adoption of RPM as a method of software installation makes me think that possibly IBM sees a transition plan where AIX gets supplanted with Linux over time. Again, this is just conjecture. My fears are that those who care about FOSS in IBM and RedHat will be pushed aside by those in IBM who'll want a short term return on investment that makes the shareholders happy. Tim.
