Re: DVI Initial Resolution
by Dennis Payne Feb. 26, 2019

Feb. 26, 2019

Yes but I refuse to go backward unless I have to. xrandr is read only under Wayland. I found a simpler solution to my problem. The TV has an audio input next to the VGA input that I didn't notice. Of course I'll have to buy a VGA cable since I don't think my son will appreciate losing his monitor cable for the project. Still need to get a software interface running which doesn't need a mouse and keyboard hooked up. EmulationStation has been suggested. I plan on using open source games not emulators but it has "ports" which allows running native applications. Just have to build it under Fedora to test.

DVI Initial Resolution
by Dennis Payne Feb. 25, 2019

Feb. 25, 2019

I've had the cub scouts build an arcade machine. The TV being used for display is connected by DVI. Fedora defaults to a resolution the TV does not support. If I hookup a monitor on the VGA port I can set the resolution of the second monitor but it switches back to an unsupported resolution when the second monitor is disconnected. Anyone know how to force a specific resolution on boot? -- Dennis Payne <dulsi(a)identicalsoftware.com>

Reminder: Meeting Tomorrow (Feb. 21st) Topic: AWX Please note location!!!
by Tim Keller Feb. 20, 2019

Feb. 20, 2019

Hey Gang, This is a reminder that we've got a meeting tomorrow! Time: 7pm Date: Feb. 21st 2019 Location: Fuller Labs, Beckett Conference Room (Room 246) https://maps.wpi.edu/?id=609#!m/105273 Topic: AWX AWX is a platform for managing the automation of running ansible playbooks. My talk will include an overview of ansible / git / gitlab and AWX as they fit together as a system to manage configurations and software. For those who use puppet/chef/salt, I'm sure there will be lively comparisons. Refreshments and snacks will be provided and afterwards we'll head off (likely to the Boynton) to continue the conversation.

Reminder: WLUG Meeting THIS Thursday (2/21/2017): Topic: AWX
by Tim Keller Feb. 19, 2019

Feb. 19, 2019

Hey Everybody, We've got a meeting on Wednesday Location: Fuller Labs, Beckett Conference Room, RM 246 Time: 7PM Topic: AWX and Ansible. AWX is the open source upstream version of Ansible Tower. This is a system that automates the running of ansible playbooks on hosts. What's ansible? Ansible is a management and configuration system for installing / modifying and maintaining linux/unix machines. What's cooler is that AWX can natively use git to manage configs. I'll talk about ansible, playbooks and then AWX. As usual, snacks and refreshments will be provided and we'll head off for dinner afterwards to continue to conversation.

charter.net is blocking all Digital Ocean droplet email
by John Stoffel Feb. 13, 2019

Feb. 13, 2019

I need to vent here. Charter.net which provides my internet, sucks. They are now refusing to accept email from *any* IP blocks owned by Digital Ocean, even though I've got a good mail setup on a droplet there, with proper DNS entries, SPF, etc. So I'm looking to spin up a new instance on some other provider, or I'm going to try and route the email via my @charter.net account that I have since I'm a customer. And I have opened a ticket with them. No answer. Jerks. What do people think of Vultr.com? Seems pretty comparable... I just wonder when Charter will block their IP blocks... Jerks. I think it's too expensive to buy an IPv4 address for more permanent use, since it's too easy for that block of 256 to be blanket banned by some jerks. Grr!!!!! John

I’m struggling w/ printers in a small office and i've struggled to get any kind of guidance on-line. The volume of pages printed at the office is probably around 100 pages a day and there are 4 printers — all HPs and all consumer grade — each printer has its purpose, e.g. there's an 11x17 printer, one color laser, one BW laster, one color inkjet. The office is all iMACs, which connect to a Linux CUPS server. The iMacs were networking directly w/ the printers, but i added the CUPS server to try to mitigate the poor reliability with only marginal results. Routinely printers become “paused” in CUPS so i need to go in and ‘unpause’ them, also some printers just fall of the network entirely. Inevitably the only printer that works most of the time is the ink-jet which is a lot more expensive to re-fill. I’m looking for a reliable solution. If anyone has a recomendation that’d be great!

Demon haunted windows 10 laptop...
by Tim Keller Jan. 6, 2019

Jan. 6, 2019

So my trusty old piece of crap finally, well crapped out. My company gave me a shiny new Lenovo 470 but it came with windows 10... no worries I'll just quick grab the 18.10 ubuntu iso and use one of the various tools to create a bootable USB... The *moment* I plugged it into my ethernet network, all hell broke loose. I didn't want to hook it up to my wifi because I assume it'll just send my wifi info back to a mothership somewhere. My Verizion AP / router promptly crashed, hard. I had to yank the power sing the ABC song for it to fully discharge and reboot. Windows... evil to the core... -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Dec. WLUG meeting reminder! Topic: DMARC, SPF and DKIM
by Tim Keller Jan. 5, 2019

Jan. 5, 2019

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".

new/old toy soon? (yet another Gigabyte GA-NNN looming)
by Doug Mildram Dec. 13, 2018

Dec. 13, 2018

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 $100+ for the combo you CAN still find online if you dare and you get lucky that it really works for you. ...below, tangent about the seller i will meet this weekend. Sounds very smart/honest! I almost got him interested in our meeting. He said: (plus, he's a CS engr) Hello network engineer, me> Engineer too....I also a) use Linux only at home b) used Linux only on that machine, rock solid :) The cpu does not come with embedded gpu : I saved 10$ at the time, too bad now!

desktop (wife=moved->linux Mint) MB/sata/grub fun
by Doug Mildram Dec. 12, 2018

Dec. 12, 2018

Warning: there's a couple "fun" ( my definition for "new to me") errors/areas in this LONG email. 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 ... 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.... (well, 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 would fix a few things, nothing scary for an ex-unix-sysadmin, and 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). Worse (not that we care!) near the end of this story, the Patriots gave up cool kickoff return with a lead and 0:04 left. But timing-wise, I'm glad I had a few hours in the living room to debug all this. 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 exported it all, 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 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. Desired talk/take-home: linux BOOT steps you don't want to know. -doug

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.

mailing list issues
by Anderson, Charles R Dec. 10, 2018

Dec. 10, 2018

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.

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

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.

OpenGameArt Movie Video Game
by Dennis Payne Dec. 4, 2018

Dec. 4, 2018

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>

Reminder! WLUG Meeting NEXT week! Nov. 8th, 2018! NOTE: LOCATION CHANGE!
by Tim Keller Nov. 2, 2018

Nov. 2, 2018

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".

Eagle to KiCad conversion?
by John Stoffel Oct. 19, 2018

Oct. 19, 2018

Guys, This is a total shot in the dark, but I'm wondering if anyone here has taken an Eagle project design, stripped out pretty much everything but the holes and outline of a board, and them imported it all into KiCad 5? I'm trying to build a cape for an AdaFruit Gemma M0 board (which I'll be happy to talk about at some point down the line at a meeting) where it auto-matically turns my sound bar on/off and the TV is turned on/off. Not more having to hunt for the sound bar remote! I've been vaguely beating my head against the wall here, esp since it's my first ever board design. Lots to learn! John

Pocket Arcade and Tiny Arcade

I received a Tiny Arcade from Tiny Circuits. It is an interesting toy. I've had a lot of fun playing with it. They recently released the Pocket Arcade. I purchased two. This is even better than the Tiny Arcade. I've been working on a new game for the system. It is a pokemon like game where you paint your monsters. It's still early in development. I've been writing about the development. http://identicalsoftware.com/games/colormonster http://identicalsoftware.com/games/colormonster2 -- Dennis Payne dulsi(a)identicalsoftware.com Roon's Raccoon Sprintladder: https://ideas.lego.com/projects/126010

Charter Telephone reviews, boylston?
by John Stoffel Sept. 29, 2018

Sept. 29, 2018

Hi, Anyone on here using Charter Telephone VOIP service? I've currently got Verizon, but the wife hates it because our phone lines get flaky all the time, esp when it rains. So I'm thinking to save money and combine all my stuff onto Charter. I've already got High Speed internet and regular old cable. Not wild about Digital Cable since I'm happy with Tivo and I don't want yet another set top box to have to deal with... So, any horror stories about Charter Phone VOIP quality and service? Thanks, John

Sept. 12, 2018

Hey Everybody, This is a reminder we've got a meeting on Thursday Sept. 13th, 2018. Time: 7pm Location: WPI Campus Center Mid Century Rm (rm 331) "The usual spot" Topic: git LFS (Large File Support) I thought I would give a quick talk using git as a backup solution for larger files. After that I figured the conversation would branch out. I'd also like to poll the group and see what people would be interested in for topics. As usual snacks and refreshments will be provided and we'll head off to dinner afterwards to continue the conversation. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

This project started because of a certain obsession of our CEO to drive as many monitors off one PC as possible. We put together a build using8x Radeon 7870s with 6x Mini DisplayPort outputs (the price spiked after we bought these for some reason) with2x Intel Xeon E5-2630 V4 , all tied together in a SuperMicro 4028GR-TR2.

With this all in mind, and the knowledge that we may have to write some funky Xorg configs, we pulled the trigger on all of it, and would attempt to drive as many monitors as we had on hand in the office. We decided to load Fedora on this machine, which should be able to drive MST with the included amdgpu driver, thanks to patches that were added to kernel 4.15, and some DC display code settings that were enabled in kernel 4.17. With all of this, we were able to successfully drive ... two displays off each MST hub, instead of the expected four. Not as fruitful as we may have hoped, but hey, 96 monitors would still be awesome. Out of sheer curiosity, we threw Windows on another SSD, and discovered that Windows could drive four displays off each MST hub, but we were getting hard limited to six monitors per card, no matter what we tried. We hypothesized that this might be due to theproprietary AMD driver setting an arbitrary limit, and thought we might be able to still pull off the 12 monitors per card in Linux. A couple of small scripts later, we were up and running with six monitors on one card. Upon adding the seventh and re-running our script, we were greeted with the following.

I don't quite know enough about how video cards work to make an informed decision about what's going on, but my hypothesis is that the card's firmware is what transmits how many outputs we can use, so we may be SOL in the department of getting more CRTCs, but perhaps there may be some way to trick Xorg into rendering the content of one CRTC across multiple monitors? Not sure. Would love to hear what you all think.

Reconnecting with my media drive
by Richard Klein Aug. 9, 2018

Aug. 9, 2018

When I was running Debian, I had most of my media segregated on a Seagate SSHD. That's still in the system now that I'm running Mint. I'm trying to get Plex up and running again. The file manager shows the media drive mounted, but shows nothing on it. I don't see it listed in fstab. I don't remember how it was formatted, but I think it's an ext4 drive.

Hey Gang, We've got a meeting on Thursday! Time @ Location: 7pm @ WPI Mid Century Room (Rm 331) aka, the usual spot Topic: Bro Network Security Monitor Presenter: Eric Martin Veteran WLUG member Eric Martin will be giving a talk about "Bro" What's Bro? Bro is a FOSS framework and event engine for analyzing network traffic. First developed at LBNL in 1995 it is used on public, private and personal networks provide robust indepth network usage and threat analysis. Check out http://www.bro.org for more details. Eric's talk will be focused around using Bro to understand the flow of traffic around devices on our home network. As we add an ever increasing set of devices that have the words "IoT" and/or Smart in their names, it matters that we know what these devices are doing and who they're talking to.

Desktop distro
by Richard Klein Aug. 6, 2018

Aug. 6, 2018

I'm having trouble deciding which distro to install on my new SSD. It's the only desktop computer in the house, so it's used for web, email, etc, plus it's a Plex server. DistroWatch.com shows Manjaro being really popular right now, but I've never heard of it. It's based on Arch, which I've heard of, but never tried. I see that Arch uses Pacman for a package manager. I'm used to APT; I'm not sure if I'd like Pacman. So anyway, I thought I'd ask for suggestions. -- Rich

Full Home folder
by Richard Klein July 30, 2018

July 30, 2018

I found today that my Home folder is full. The culprit seems to have been a roughly 1/2 terabyte .xsession-errors file. I deleted it, but 'emptying the trash' didn't seem to be clearing any space. I found that everything I'd thought I'd deleted recently seemed to still be sitting in $uname/.local/share/Trash. I selected everything in that folder and typed shift+delete. Now nothing shows in the Trash folder, but my Home folder is still full. I rebooted, and that's still the case. What now?

IMPORTANT: WLUG Mailing List Move Complete

By now everyone should have received a welcome message from the new list server, wlug(a)lists.wlug.org, along with instructions for setting your password. I'm still working on getting the archives moved over. Please use only the new list address wlug(a)lists.wlug.org to post--if you use an old address you'll get a reminder to use the new one, at least until a few weeks from now when the old server will have to go offline. I'd also like to thank our generous host http://mailman3.com for providing our new mailing list and Hyperkitty web forum free of charge.

IMPORTANT: Upcoming WLUG Mailing List Move
by Chuck Anderson July 19, 2018

July 19, 2018

After 18+ years of the WLUG mailing list being graciously hosted on the WPI campus network at no cost to WLUG, we must move to an external mailing list host as WPI prepares to shut down its Linux email infrastructure after moving to Microsoft Office 365 in the cloud. Phase 1 begins Monday, July 23, 2018, but the shutdown for third-party domains like wlug.org is planned for mid- to late-August. Luckily, we have a new sponsor who has generously offered to host our mailing list at no cost on Mailman 3 with Hyperkitty! We are currently setting up the new mailing list and working out the details, but I wanted to send out a "heads up" message to everyone before anything changes. The plan is to set up the new host in parallel with the existing host, but this necessitates a change in the mailing list address. I also plan to copy the existing subscriber list (and archives if possible) over to the new list, but if that isn't possible I'll let everyone know. More details will be coming soon. I'll also update the WLUG website http://www.wlug.org/ with the new mailing list details when we are ready, so watch that space in case we lose the ability to send to the old list! Worst case, we have the subscriber list backed up and could send an email to everyone individually if it becomes necessary. Thanks, Chuck

TinyArcade and Arduboy
by Dennis Payne July 18, 2018

July 18, 2018

I've been playing around with the Tiny Arcade by Tiny Circuits. It's been a lot of fun programming. The initial development of Color Monster is documented here: http://identicalsoftware.com/games/colormonster The new Pocket Arcade has me really interested but it isn't available yet. I stumbled across the Arduboy. (Stumbled again? I'm pretty sure I saw the kickstarter and decided against it.) Does anyone have one? What do they think of it? I think it isn't quite what I want for a system. Seems like it can be annoying to upload a new game onto the system. While I had fun with the TinyScreen Video Game Kit, I like the microsd card of the Tiny Arcade so you can have multiple games available.

UPS power backup unit needs home
by E Johnson July 13, 2018

July 13, 2018

I have a UPS power backup unit here that I can't use. This is a Cyber Power model 1000PFCLCD. This should supply around 15 minutes of power to your computer & peripherals in the event of a power outage. Enough time to shutdown your delicate operations properly, save the doc you were just working on, or put your game on pause... Purchased several years ago (for around $109), I never used it in the old place because NONE of the circuits were grounded --so it wouldn't ever do anything. Now in the new place, nothing is grounded here either! Probably it works but I was never able to test it, since it requires a grounded circuit even to charge itself. It has not been abused except by a little dust. This is about the size of eight bricks all stacked together into a box shape... Probably heavier than eight bricks. Unscented; smoke- & cat-free. Will go with your other shiny black computer decor. Someone needs this! I want you to want this! Offering it here first, FREE to good home. I am still in Worcester, now on the quieter end of Vernon St. Pickup time flexible, and we have an off-street spot where you can temporarily park. Who wants this? Let me know. Liz J

There was some talk about guix, so we'll definitely be talking about that. We'll also talk about when we want the BBQ. Personally, my vote is for Sept. Less bugs, cooler weather, etc. Obviously if someone with a pool wants to pitch for August I can be persuaded! Location: WPI Campus Center Rm 301 (Hagglund room) When you come up the stairs go right instead of left. Refreshments and snacks will be provided. Afterwards we'll head off for dinner and keep up the conversation. Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

You're thinking of last years BBQ! My plan was to have the BBQ either August or Sept. Being anywhere near a grill when it's 100 degrees just isn't enjoyable.

Free to a good home: HP PSC 1315xi All in one printer

Have you been waiting to get yourself one of those awesome web connected printers, but didn't want to shell out the big bucks? Well... you're out of luck, this is NOT one of those printers. If however, you'd like a reliable inkjet printer that works well with linux, let me know. The scanner / copier / printing functions all work. Better yet, it has new ink cartridges in it as well! Mind you, it is an elderly printer, but I've had zero issues with it. The only con is that HP branded ink cartridges are getting expensive, but the knockoffs work just fine as well. Let me know if you'd like it and I'll hand it over at the meeting tonight. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Great meeting last night!
by Tim Keller April 13, 2018

April 13, 2018

Hey Everybody, Last night's meeting was fantastic! It's always great to get a full house! For those of you who were unable to make it, there were a number of fantastic mini talks. Login gave a great 15 minute rundown regarding the "audit2allow" tool to generate selinux rules. Login then proceeded to show how SElinux is running in lots of places... and then SSH'd into his phone to show that it was also run SElinux. kudos on the sshing over bluetooth from your laptop... that was cool. Greg then gave a great demo on a very lightweight security oriented linux called "Heads" (as opposed to the more well known "Tails" distribution. What was more amazing was that he was running it on a pretty old laptop and it was zippy... Though their support for mirroring displays could be a bit clearer! It was really impressive what you can do with a two core pentium laptop and a usb stick! Lastly, Chuck showed off Qubes. While the install didn't finish until we'd come back from dinner! Chuck was able to talk about the idea of separating applications into different Xen domains. It was really cool. Though we talked about this at and after dinner... I'm fearful that Xen is going the way of the dodo... I wonder if in the future the Qubes people will support other hypervisors. Thank to Login, Greg and Chuck for presenting and thanks to everybody for turning it into a lively and interesting round table discussion. Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Re: [Wlug] Resurrecting old computers with Linux...

April 1, 2018

John, If I remember correctly, the equivalent of "assembly language" for the 1401 (either the IBM model or the IMB model) was "Autocoder". The IBM 1401 was introduced about 1961. By the time I started work at Aetna Life and Casualty in 1973, we had become the "Largest commercial user of IBM Equipment in the Free World". That means that maybe the government used more IBM computers, or that the Russians or the Chinese were using more IBM computers, but other than that AETNA WAS THE LARGEST. We AUTOMATICALLY ordered two of anything IBM announced. No sales person had to call us. IBM announced it: Aetna ordered two. So by that time we had lots of IBM 1401s and lots of Autocoder programmers. Then the IBM 360 line came out, and with it IBM's line of batch operating systems: MFT, MVT, VS-1, VS-2, and (finally) MVS. Unfortunately getting jobs into and out of these batch systems was extraordinarily painful until the Houston Automatic Spooling Priority (HASP) system (developed at the IBM Federal Systems Division of the Lyndon B. Johnson Space Flight Center in Houston, Texas) came out and made life bearable for the operators of the machines. [Editorial Side Note: These were not "Network Administrators", nor "Systems Administrators"....these were OPERATORS! As in BOFH! Never forget that! And for heaven sake RTFM!] With those also arrived a time-sharing system called CP-67 along with a small "Cambridge Monitor System" (CMS), needed because CP-67 was a Virtual Machine. Yes, a Virtual Machine in 1973! Which eventually was renamed to "VM/CMS" and "CMS" became the "Conversational Monitor System".....but I digress.... Aetna had a LOT of machines, and a LOT of Autocoder programs, and a LOT of Autocoder programmers, which they tried to convert to COBOL. Yes, COBOL, that wondrous language developed by the team headed up by my personal hero, Rear Admiral Grace Murray Hopper! After several years most of the programmers were happily writing COBOL (yes, I know that seems hard to believe, but they were) except for a few Autocoder programmers left to make bug fixes and extensions to existing Autocoder programs. Of course new programs and new systems were written in COBOL, because why would you write anything new in Autocoder. As the 1401s were replaced by 360s and (later) 370 machines, IBM created an emulator for Autocoder that operated in a 360/370 system, so you could run Autocoder programs binary compatible on your 370/370 mainframe. And when you did you almost heard the IBM choking. I never coded in Autocoder, but I did hear one story about an instruction that "rotated all of memory under the accumulator", and it was said that when that instruction (which executed gracefully on a real IBM 1401) hit the emulator on the 360/370, you could hear the machine hemorrhaging..... Over time the Autocoder programmers became gloomy. They were tired of patching old programs, and not working on any of the new, exciting systems that Aetna was writing. Aetna had written its own real-time transaction processing system called SAFARI (sorry Apple, we were first) and later on a Group Claim Payment System (ACCLAIMS), which gained a lot of people glory. Autocoder patching did not get much glory. And over time there was less and less work...the writing was on the wall. One day I came into work and found the Autocoder programmers very excited and happy. They were given NEW programs to write! "I did not know you guys had learned COBOL!" I exclaimed. "Oh, we have not learned COBOL. They are allowing us to write the new programs in Autocoder." In the late 1990s there was this panic to find old COBOL programmers who could fix potential problems with Y2K problems. I am sure that Aetna had to bring a few Autocoder programmers back from the dead. And now you know THE REST OF THE STORY.

Next WLUG meeting! April 12th, 2018! Location: WPI Student Center, Rm 331. Topic: Secure Linux Distributions
by Tim Keller March 29, 2018

March 29, 2018

Hey Gang, Our next meeting is April 12th, 2018! Would people be interested in talking about security oriented versions of Linux? We all know about Tails, and in consideration of the issues that Richard ran into with getting stuff installed on Kali, it might be interesting to compare / contrast the different options out there. What do people think? I'm thinking this would work best as having a couple of people each showing off a particular distribution. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Just plan to test enough that I feel confident it is doable before asking them. Yesterday I took pictures of Skylanders to see at what scale they still look good. At 64 pixels wide they are a little grainy. 128 pixels wide looks pretty good. Skylanders apparently has catch phrases for characters so I would like to get each kid to record a catch phrase for their character.

Does anyone have a recommendation for a RFID reader/writer for Linux (and Windows if possible)? I'm looking for a relatively inexpensive solution. My kids just got Skylanders Imaginators. I found some code to read the characters. I started thinking about the Game Design merit badge for Cub Scout Webelos. I'm wondering about the viability of building a "portal" device and having the kids make clay figures with rfids inside the base. Obviously the game would be as complex as Skylanders. I'm thinking 2D using pictures of the models.

I'm pretty sure it does manage to open the framebuffer; I get the mouse cursor at what looks to be the monitor's native resolution. It probably throws that error before it tries a different method, but obviously I don't know.

Richard, I’d bet that your packages are fine (but i’m not a betting man). It sounds too me like there is something awry w/ your X environment. Perhaps the upgraded packages don’t recognize a config buried somewhere. Here’s a couple things i would try. - Often times there a file in your home directory called .xsession-errors. I’d see if that file exists, and it may offer you some hints as to why your window manager is not starting. I recall launching X from a Graphical Login Window to be finicky in linux and error output is difficult to understand. the .xsession-errors file is where i’d look first. - Other idea is to create a new user, then login to the GUI with that user to make sure the GUI starts from a fresh environment. - The last idea i have. It sounds like you’re running gnome from the fact that your using GDM3, I believe the gnome environment files are in .gconf in your home directory. try renaming your .gconf to something like .gconf.backup.

Eric Martin forwarded me some info about the ROCA stuff from last night. It was pretty cool to see Nick do his thing on the whiteboard... I'd like to claim I followed it all, but that would be a lie! Here's the link to the ROCA stuff: https://dan.enigmabridge.com/roca-critical-vulnerability-in-infineon-securi… The other conversation that happened last night surrounded very weak public keys. https://keytester.cryptosense.com Lets you test your keys to see if they're easily factored.

The calendar on the website is a Google Calendar. Tim, Frank, and myself have access to change the calendar from any Google calendar client, including google.com/calendar. I recommend Jorte on Android, but the built-in Google calendar on Android should work fine as well. Ideally, whomever reserves a room and/or announces a meeting date/time/topic would update the calendar at the same time. Just change "only this event" so as to not mess up the default recurring schedule. The calendar is public so anyone can subscribe to it so it shows up on their own personal device(s): https://calendar.google.com/calendar?cid=bzVvc3E4NTBsazYxZThoMW4xbzFybGRiNz… Tuesday Feb 20th works for me.

Reminder: WLUG Meeting Tomorrow Jan 18th, 2018 Topic: Spectre and Meltdown!
by Tim Keller Jan. 18, 2018

Jan. 18, 2018

We've got a meeting this week! Short Topic: Spectre and Meltdown. What it is, what it does, etc. I figure this is pretty topical as many of us are starting to wrap our heads around the performance implications as well as the tackling the task of patching many systems. Location: Campus Center, Mid Century Rm 331 Time: 7pm Snacks and Refreshments will be provided. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Hi everybody, I've noticed that the Ubuntu 16.04 ISO is bootable on systems with BIOS as well as UEFI. From scratch, I've remastered Ubuntu, but my ISO file is only bootable via BIOS. I'd like to remedy that situation by figuring out what magic is needed so that my ISO file can be booted either way. I have a chroot directory in which my files live. I have scripts that convert all of that into an ISO file. My guess is that I need a new/modified incantation of mkisofs plus some additional files for UEFI. Despite a lot of searching, I've not yet found the info that I need. If you have definitive information, please let me know. Thanks!

If things like that > exist, why care about encryption vulnerability? Because with properly configured wireless and patched clients, you can be sure you are connecting to the trusted network, not a Man-in-the-Middle. It requires mutual authentication, which happens for example on the WPI wireless network by using EAP-TLS certificates. The client is supposed to verify the server's certificate and the server of course verifies the client's certificate. Unfortunately, most networks don't use EAP but rather use Pre-Shared Keys (WPA2-PSK). > If you need to patch both sides to be secure, > then you are not secure in the coffee shop no > matter what you do.

In the strictest sense this is true, but as far as the KRACK attack goes, the wireless AP side is much less likely to be a problem, because the vulnerabilities are in parts of the standards that are not often used (802.11r "Fast Roaming" for example). The client-side vulnerabilities, especially in Linux/Android, are much more serious. On Linux, the client can be tricked into using a null session key. However, in a coffee shop KRACK is moot because most coffee shops don't use encryption at all to begin with. In any case, WPI's recommendation to use the VPN if you are not sure of your device's or the network's immunity to KRACK is sound, because even if there was a M-i-t-M, they still would not be able to decrypt the VPN traffic. Security is helpful in layers. Belt-and-suspenders.

You've got to avoid computers to be fully secure. But let's not get that paranoid. I pulled Cat 5 cable through the house years ago and never use wireless, but WPI has its hair on fire, and sent Professor Diane email (through Microsoft cloud service) to install "upgrades" immediately. I told her to at least wait until she has her computer back in the office and plugged into WPI cable. I have a friend who has been without a computer for a month or two because he tried to upgrade firmware and could not re-boot. This is very embarrassing for the authors of the standard, but is it really a big problem? Several meetings ago, somebody brought a device to the WLUG meeting that, as I understood it, pretends to be a wireless router and interposes itself into any nearby connection. If things like that exist, why care about encryption vulnerability? If you need to patch both sides to be secure, then you are not secure in the coffee shop no matter what you do. In any case, if you are using the wireless to connect to a web site or "cloud" server, then the wireless connection is the least of your insecurities. -- Keith

Nothing so simple, unfortunately. This class of vulnerability is actually a collection of 10 CVEs, which encompass both the AP side and client side. If you've patched the AP side, for example, the attacker may still be able to compromise the set of session keys on the client side, and decrypt all of the client sent traffic. You've got to patch both sides to be fully secure. """ The direction in which packets can be decrypted (and possibly forged) depends on the handshake being attacked. Simplified, when attacking the 4-way handshake, we can decrypt (and forge) packets sent by the client. When attacking the Fast BSS Transition (FT) handshake, we can decrypt (and forge) packets sent towards the client. Finally, most of our attacks also allow the replay of unicast, broadcast, and multicast frames. For further details, see Section 6 of our research paper<https://www.krackattacks.com/#paper>.

So it might be that your router does not require security updates. We strongly advise you to contact your vendor for more details. In general though, you can try to mitigate attacks against routers and access points by disabling client functionality (which is for example used in repeater modes) and disabling 802.11r (fast roaming). For ordinary home users, your priority should be updating clients such as laptops and smartphones.

LEDE does a bunch of faster-paced development with the goal of having their work eventually merged back into OpenWRT. They often experiment with different ideas/features.

Hi Tim, The Anet A8 and TEVO tarantula are i3 derivatives, what with the hardware being open source. Each of these can be found on Amazon. The assembly guides are pretty cryptic though, with lots of skipped steps and a lack of images. However, If Ab Initio can afford the $600, I would seriously recommend getting Josef Prusa's original version, which he sells on his website. https://shop.prusa3d.com/en/3d-printers/59-original-prusa-i3-mk2-kit.html?g… The manuals are amazing, with an active community of people making revisions on Github. Monoprice also has a fork of the i3 which they sell as well. https://www.monoprice.com/product?p_id=13860&gclid=EAIaIQobChMI4q3brfnj1gIV… In terms of assembly time: the A8, the Tarantula, and the original i3 will all take a couple days of (hopefully some poor intern's) time to assemble and test. The Monoprice i3 ships semi-assembled, and you can get printing within a couple hours.
