Backup/restore question
by Fred 22 Dec '23

22 Dec '23

Internet search is going nowhere on this: I have a backup of my home dir from OS 15.0 and am going to do a fresh install of 15.5, with the idea that I can restore the home backup. Not having done this before, what issues do you see me having? I have a crapload of stuff on this system that, although dated, is working. I would hate to break it. Obviously all the documents are no prob, ditto the pictures (I started to say images but that would conjure up a different "image"). The shared dir with VirtualBox is ok but I think that I would have to install the latest VB, which has its own problem with finding the product codes of the win systems there. I seem to remember looking in the registry for that info. Maybe things like browser history or bookmarks or saved passwords (not sure where they are stored, maybe not in /home) I am not sure what else is going to blindside me, which is the reason for the shout out. Thanks

Mongodb
by Roger Oberholtzer 22 Dec '23

22 Dec '23

Hi all, I am exploring using a Google image database ( https://storage.googleapis.com/openimages/web/index.html) to train a local YOLO/Darknet neural network. As it contains 1.9 million images, I obviously need to be selective about the things I want to train for. So I was looking at the suggested FiftyOne application (https://docs.voxel51.com/index.html). Looks promising. Except I cannot run it. I get an error that mongod (which I guess is a MongoDB access daemon) cannot be found. I recognize the name. But I have not used it. I searched on OBS to see if it is available. All I see are some user packages that are all failing. This surprised me as I would have thought MongoDB was a big thing in the Python world. And SUSE do support Python. My questions are: Is anyone using MongoDB on openSUSE, especially Tumbleweed? If so, where did you find it? I looked at building MongoDB and saw this odd requirement ( https://github.com/mongodb/mongo/blob/master/docs/building.md): "About 13 GB of free disk space for the core binaries (mongod, mongos, and mongo) and about 600 GB for the install-all target." A typo? They meant MB instead of GB? BTW, it is specifically mongod that FiftyOne complains about. There is no populated database when building and installing it. So what on earth can require 600GB? As an aside, I was just introduced to the Python 3.11 feature that does not like one to mix using zypper and pip. I prefer zypper as it maintains things as part of my regular updating. And so that method is enabled by default. The complaint is about an 'externally-managed-environment'. To be honest it makes sense. I have always wondered how mixing zypper and pip would work. My solution was to make a Python virtual environment for this. And that uses pip because FiftyOne seems only available via pip. TIA for any pointers. -- Roger Oberholtzer

iSCSI . . OOO! fuzzy! or eeewww! scuzzy!
by joe a 21 Dec '23

21 Dec '23

Any experience with iScsi on LEAP 15.5 or the like? Making nice with VmWare ESXi 6.5 and maybe above? I may want to spend some cold dark winter days making use of a few excess 64 bit machines I have laying about.

Screen blanks while watching video. Leap 15.5 KDE
by James Knott 21 Dec '23

21 Dec '23

I installed 15.5 a couple of weeks ago and one annoyance is the screen will blank after a few minutes while watching a video, unless I move the mouse or press a key occasionally. Is there any way to stop that behaviour, while a video is playing? tnx jk

How can openSUSE udev rule for /dev/ttyACM0 impact communication with the device?
by David C. Rankin 21 Dec '23

21 Dec '23

All, This is way in the weeds of a udev question -- something I know little about, but I've pulled my hair out trying to find out why when connected to openSUSE the device simply doesn't provide I/O responses from the Pico after high-activity on the Pico? Simply rebooting into windows, same Pico, same USB same everything -- all works. Unplug the Pico, carry 8-foot to Arch box, plug-in, everything works, reboot openSUSE, carry Pico back from Arch box, plug into same USB as before and no output after high-activity on the Pico on openSUSE. The card isn't locked, simply pressing Enter restores shell prompt, so it is just something happening on the USB port that is preventing *some* I/O from coming through. minicom, picocom, tip, doesn't matter. 9600 baud or 115200 baud, doesn't matter, there is just something about how /dev/ttyACM0 is configured or accessed on openSUSE that is causing the issue. stty settings are exactly the same between Arch and openSUSE. When hooked to the Arch box, access is from openSUSE via ssh using the same terminal. Peering through udevadm info output there are subtle difference in how the udev rule sets up the device which has me wondering if those small differences in setup is what is responsible for the behavior I see. I don't know enough about it to know so I need help. The Archlinux udevadmin info output for /dev/ttyACM0 is at: https://paste.opensuse.org/bb73cdfe5dd7 The openSUSE udevadmin info output for /dev/ttyACM0 is at: https://paste.opensuse.org/2c4d323524ee The only things that stand out are the openSUSE configures "kids" info for the device while Arch has no "kids" and there are difference in some settings, these being some that were noted, e.g. Arch: ATTRS{manufacturer}=="Raspberry Pi" ... (power/async not set) ATTRS{power/control}=="on" ATTRS{power/level}=="on" ... ATTRS{power/runtime_status}=="active" ATTRS{power/runtime_suspended_time}=="0" ... ATTRS{quirks}=="0x0" ATTRS{removable}=="unknown" ATTRS{remove}=="(not readable)" ATTRS{rx_lanes}=="1" ATTRS{serial}=="E6612483CB6D7F25" ATTRS{speed}=="12" ATTRS{tx_lanes}=="1" ATTRS{urbnum}=="250" ATTRS{version}==" 1.10" looking at parent device '/devices/pci0000:00/0000:00:1d.3': ... ATTRS{consistent_dma_mask_bits}=="32" ATTRS{d3cold_allowed}=="0" ATTRS{device}=="0x27cb" ATTRS{dma_mask_bits}=="32" openSUSE: ATTRS{manufacturer}=="Raspberry Pi" ... ATTRS{power/async}=="enabled" ATTRS{power/control}=="auto" ATTRS{power/level}=="auto" ... ATTRS{power/runtime_status}=="suspended" ATTRS{power/runtime_suspended_time}=="75332" ... ATTRS{product}=="Picoprobe" ATTRS{quirks}=="0x0" ATTRS{removable}=="unknown" ATTRS{rx_lanes}=="1" ATTRS{serial}=="E6612483CB6D7F25" ATTRS{speed}=="12" ATTRS{tx_lanes}=="1" ATTRS{urbnum}=="273" ATTRS{version}==" 1.10" looking at parent device '/devices/pci0000:00/0000:00:1c.7/0000:26:00.0': ... ATTRS{consistent_dma_mask_bits}=="64" ATTRS{current_link_speed}=="5.0 GT/s PCIe" ATTRS{current_link_width}=="1" ATTRS{d3cold_allowed}=="1" ATTRS{device}=="0x0194" ATTRS{dma_mask_bits}=="64" But admittedly, those settings do not mean much to me. Can anyone think of any difference in udev that may explain the I/O with the pico not all being there on openSUSE, but being 100% fine when rebooting to windows, or when plugging the connection into any other box I have? Having eliminated everything else I can think of and having tested the same Pico on the same USB port on my laptop and then having tested plugged into any other box, there is something different about the /dev/ttyACM0 device when it is connected to openSUSE - but I can't quite figure out what. All help, ideas, welcomed. This was uncovered as part of an issue being worked on github, though not 100% related to the port, it contains all the elimination of other possibilities of what it could be (for any interested reader): https://github.com/carlk3/no-OS-FatFS-SD-SPI-RPi-Pico/issues/91 -- David C.

Extra NTP server address
by James Knott 20 Dec '23

20 Dec '23

I run my own NTP server, which can be reached with both IPv4 and IPv6. However, when I check with Wireshark, I see NTP requests going not only to my server, but also to an IPv4 address on the Internet. This happens with both my desktop system and ThinkPad, but they have different external addresses, in addition to my server. I use the host name for the server address in NTP Configuration. Any idea where that other address comes from?

zypper update shows locked files
by Frank McCormick 19 Dec '23

19 Dec '23

Did my usual zypper dup this morning and for the first time saw this message about locked files. The following 2 items are locked and will not be changed by any action: Installed: patterns-base-basesystem patterns-base-x11 Nothing to do. frank@desktop-tumbleweed:~> I assume this means if there are updates to those files they won't be sucessful. How do I change this ? Thanks
