by Linux Journal 21 May '19

21 May '19

Hello Community Advisory Members, holepunch.io [https://holepunch.io/signup] is a new tunneling service developed by some folks at London Trust Media (our parent company), and they'd like to share it with you for free. The service is currently in beta testing, and we are sending this out to you, our LUG community advisors. We would appreciate if you could also pass this along to your LUG members. The development team would love to hear your feedback, so please tell them what you like or don't like, and let them know if you find any bugs (email [support(a)holepunch.io] You can use holepunch.io [https://holepunch.io/signup] to host a website locally over http or https and share it with friends or clients via a public URL (support for tcp or udp coming in the near future). To get started, simply sign up [https://holepunch.io/signup] and then go to the download page [https://holepunch.io/download] to get the punch CLI that you will use for starting a tunnel. You also can use the CLI to do other things [https://holepunch.io/docs] like reserving a specific subdomain to use for your site. Now, other services similar to holepunch.io do exist, but holepunch.io is focused on providing the best quality at a lower price while being more private, secure and open than other options. The holepunch.io team is making business, architectural and development decisions that will allow you to trust your data going through their service.

IEEE Vic Talk: Tue 21 May 18:30: Prof J. Lygeros: Feedback everywhere
by Rodney Brown 20 May '19

20 May '19

*Title:* Feedback everywhere *Speaker:* Professor John Lygeros, Professor of Computation and Control and Head, Department of Information Technology and Electrical Engineering, ETH Zurich *Date/Time:* 6.30-7.30pm, refreshments from 6pm *Location: *Woodward Conference Centre, 10th floor, Melbourne Law (Building 106), 185 Pelham St, Carlton VIC 3053 *Registration: *https://www.eventbrite.com.au/e/2019-miegunyah-public-lecture-feedback-everywhere-tickets-59205215393 <http://enotice.ieee.org/link.cfm?r=O_5crvo8-OpaaQy2hmvJVQ~~&pe=OLeDtmo5tVsI…> *Abstract:* What do self driving cars, power grids and homeostasis in biology have in common? Seemingly not much. If one looks "under the hood", however, one discovers that they all rely on a common principle that renders their operation robust and reliable. This principle, known as feedback, is intuitive: see where you are, compare to where you want to be, and move in the direction that reduces the difference between the two. Though the feedback principle itself is simple to explain, understanding its implications, uses and limitations is far from it and forms the topic of a branch of engineering known as automatic control. *23rd May 2019* Winprop workshop: AP-MTT is also co-sponsoring a free workshop on wireless propagation modelling. Again further details are available from http://sites.ieee.org/vic-apmtt/ <http://enotice.ieee.org/link.cfm?r=O_5crvo8-OpaaQy2hmvJVQ~~&pe=Kz_axBBP47bd…> and registration is by email to marketing-anz(a)altair.com <mailto:marketing-anz@altair.com> http://www.ieeevic.org/

USB drive errors
by stripes theotoky 18 May '19

18 May '19

I have a WD passport USB drive that has been working fine. Just plugged it in and get input / output errors and it won't mount. Mounted it manually with mount -t ntfs-3g /dev/sdb1 /mnt it mounts fine and ls shows this. ls: cannot access 'Locale': Input/output error total 4845912 drwxrwxrwx 1 root root 4096 Apr 23 11:11 . drwxr-xr-x 23 root root 4096 May 18 19:03 .. drwxrwxrwx 1 root root 4096 Feb 25 2018 apache2-Debian drwxrwxrwx 1 root root 4096 Dec 15 2012 Extras d????????? ? ? ? ? ?

Any suggesting apart from using rsync to copy everything else off the drive and formatting it? Stripes. -- Stripes Theotoky -37 .713869 145.050562

Mixed results with Linux 5.1
by Duncan Roe 13 May '19

13 May '19

Hi all, Following Andrew's exhortations at the last main meeting, I built 5.1 and installed it on my laptop. My 3 AMD GPU bugs are all fixed! Very impressive, since I haven't had any Bugzilla email about them for months. At least, I suppose they're fixed: the symptoms don't show any more. On checking logs I saw 1 Oops (from 3 boots), and it looked similar to the ones I used to see all the time. Confidently I installed 5.1 as my default desktop system. This was a disaster. The system came up to the login prompt very quickly, without changing from the initial terminal font to a smaller one as it usually did. There was a message from INIT that "SV" was respawning too quickly. When I supplied user name and password, I just got the login prompt again. I went back to 5.0 and checked what was in debug.log (which logs everything). And there was nothing at all! No hint that 5.1 had ever started - just a 7 minute gap between the last 5.0 shutdown and 5.0 starting. I'm at a bit of a loss as to how to report this - does anyone have a suggestion? Cheers ... Duncan.

Suggestion for 2 in 1 laptop
by H 06 May '19

06 May '19

I am looking to get a 2 in 1 laptop with a touch screen for personal / hobbyist use. I would like 512 GB of storage for Linux (datafiles), but also to be able to boot Windows. I have been on various manufacturers and retailers websites and can find only limited technical information I don't think the SSD available / supported are large enough for dual boot. I am therefore thinking of getting something with a M.2 SSD socket, and changing over the card depending on which O/S I want to use. Swapping cards does not strike me as problem (I did it regularly on my previous laptop) Can anyone advise where linux support for touch screens is at? (I heard some dated stories that it is not there yet - I'd like to run opensuse (kde), but hear Gnome (ubuntu) offers better support, happy to try other distos if suggested ) Can anyone advise about '2 in 1s' and whether / which have replaceable M.2 SSD cards? Many thanks, H

Re: [MLUG] Xserver
by stripes theotoky 29 Apr '19

29 Apr '19

Thank you all for the advice regarding the Xserver problems. I am still not sure what happened here but following your advice and with some other ideas this worked. Disable nouveau when booting press e add nouveau.modeset=0 press F10. This boots and allows me to log in. ps -A | grep shows that startx, xinit and Xorg are not running so clearly a step in the right direction. startx fails with no screens found and that it is using /etc/X11/xorg.conf. Renaming /etc/X11/xorg.conf to /etc/X11/xorg.conf.bak and trying again also fails with no screens found but now reports that it is using /usr/share/X11/xorg.conf.d A quick look in there shows a file 20-nouveau.conf which identifies the video card as Nvidia and uses the nouveau driver. Renaming that to 20-nouveau.conf.bak and restarting the system brings everything up normally. I have no idea what happened, what was wrong with these files or why renaming them worked. In fact not even sure what video drivers I am running right now. Much still to investigate. Thanks for the suggestions.

Xserver
by stripes theotoky 25 Apr '19

25 Apr '19

Following the latest update on my Devuan box I have lost the Xserver. The box boots normally then instead of a log in screen it is just black. Pressing Alt Ctrl F1 gets me to a terminal where i can log in. ps -A | grep shows that slim and Xorg are running. Xorg on tty7. Pressing alt ctrl F7 turn the cursor off in tty1 but does nothing else. I am using the nouveau drivers. dmesg seems to show them loaded. I have run apt purge nvidia* just to be sure they are not installed. nothing is blacklisted in /etc/modprobe.d/ xorg.conf refers to nouveau modprobe shows the nouveau drivers loaded. Any ideas on where to go from here? Stripes Stripes Theotoky -37 .713869 145.050562

Request for floppy drives.
by Keith Salter 10 Apr '19

10 Apr '19

Some time ago, Andrew Pam expressed a need for floppy drives for a particular project he was considering. My collection of at least 12 drives, mostly of the " no facia " version , would be immediately available, should the need remain. Keith. <cyberfibre(a)fastmail.com>

android-x86 and fails to boot grub2
by Nic Baxter 08 Apr '19

08 Apr '19

Hi All After the posts last week about android I thought I would try android-x86 on my Samsung Slate currently running Debian Buster. At first I tried the rpm version using alien. The scripts configure android with qemu and also adds a grub entry for dual booting. The qemu version works well. When I tried to boot neither android nor Debian would boot. Android would just return to the grub screen and Debian would stuck at ' Loading Linux 4.19.0-4-amd64' . So more fool me for trying the alien rpm root. So boot with rescue usb, chroot, and alien -e android-x86 to remove android. Update-grub and reboot. All OK boots into Debian. So make Android-x86 boot usb and reboot into installation mode. Install Android into /dev/sda1 without formatting as per http://www.android-x86.org/documents/installhowto. Do not install grub. Installation finishes. Option to run android with out rebooting, works fine. Reboot and can't get passed grub. Same symptoms as before. Booting with rescue usb, chroot, and update-grub appears to work but after reboot won't get passed grub. Then at grub screen click on c and get grub shell. set root(hd0,1) and get the grub prompt again, using ls I can see all of the required files with tab to autocomplete so, linux /boot/vmlinuz-4.19.0-4-amd64 root=/dev/sda1 sticks. Doesn't return to grub prompt. No timeout. Get supergrub usb. Boot, sees the partition and can boot Debian. What am I missing here? I getting close to nuking everything and reinstalling. Any ideas? Cheers Nic

linux heart rate monitor / activity tracker?
by Craig Sanders 06 Apr '19

06 Apr '19

I'm looking for both wearable hardware and software for heart rate monitoring on linux. On wrist or chest strap is fine. Heart rate monitoring is essential. Oxygen saturation and ECG functionality would be nice too. I've got a better idea of what I **DON'T** want than what I do. I don't want anything that requires sync to a corporate server, I want to BUY a product, not BE one (optional syncing is fine, I can choose not to use it). I just want something that gathers data and either transmits it in real time to my bluetooth-paired desktop machine and/or android[1] device, or logs the data for later download. I'll also need software to display and/or analyse the data. I've seen lots of cheap devices on ebay for $10-$20 but have no idea if they can be made to work with linux or if they use their own proprietary protocols and only work with their spyware app. I'd prefer to avoid brand name equipment, because I see no good reason to pay $300 or $400 for hardware not significantly better than the stuff that sells for under $20 - especially when I explicitly do not want any "value added" cloud services they provide, services that get promoted as features but I see as spying malware. in short what i'm after is: * cheap * open source data acquisition, visualisation, & analysis * open data formats * no mandatory spyware service Any clues or pointers to relevant hardware or software would be appreciated. [1] i've found https://github.com/Freeyourgadget/Gadgetbridge (which is availabled on the F-Droid app store) so something compatible with that would be good. craig -- craig sanders <cas(a)taz.net.au>
