LEAP 15.1 Smart homes / Smart devices questions

March 4, 2020, 3:21 am

Does anyone know if there is a common/preferred software package for controlling smart home devices?

Also, when buying these devices, is there some particular protocol to look for to make sure the devices are compatible with Linux/opensource software?

I just started looking at smart devices and bought myself a couple of smart switches and have been playing with them but then thought I should see what's happening in the opensource community before I risk getting too committed to anything commercial.

Also, is this a case where I probably should look at something like a raspberry pi device instead of using my desktop? I've had friends get into the raspberry pi's but I never quite had time but this might be a good excuse.

TUMBLEWEED Unable to upload code to Arduino Nano, getting error, "avrdude: stk500_getsync() attempt 1 of 10"

I am using a generic Arduino Nano (sold in China) and unable to upload a my code.The device is working OK. I checked with my MacBook Pro and it was also working fine with Ubuntu Linux before I switch Distros.

I've gone through the exact same steps to set things up. Added $USER to the dialout group,

Code:
$ ls -l /dev/ttyU*

crw-rw---- 1 devguy dialout 188, 0 Mar  4 07:14 /dev/ttyUSB0
Checked device is attached to the USB port

Code:
$ lsusb

Bus 001 Device 010: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter
I've used dmesg to check the device exists, here is the output

Code:
[ 4047.295097] usb 1-8: New USB device found, idVendor=1a86, idProduct=7523, bcdDevice= 2.62
[ 4047.295099] usb 1-8: New USB device strings: Mfr=0, Product=2, SerialNumber=0
[ 4047.295100] usb 1-8: Product: USB2.0-Serial
[ 4047.332500] usbcore: registered new interface driver usbserial_generic
[ 4047.332505] usbserial: USB Serial support registered for generic
[ 4047.333609] usbcore: registered new interface driver ch341
[ 4047.333614] usbserial: USB Serial support registered for ch341-uart
[ 4047.333625] ch341 1-8:1.0: ch341-uart converter detected
[ 4047.342834] usb 1-8: ch341-uart converter now attached to ttyUSB0
I believe this device is ch341 compatible

Code:
$ lsmod|grep ch341

ch341                  20480  0
usbserial              61440  1 ch341
usbcore              315392  9 usbserial,xhci_hcd,snd_usb_audio,usbhid,snd_usbmidi_lib,uvcvideo,btusb,xhci_pci,ch341
Maybe the problem is the "ch341" module is not getting loaded? This command does not output anything.

Code:
sudo modprobe ch341

The device connection is on ttyUSB0, but the Arduino IDE refused to upload the code?

Anyone have a reference describing what RAID1C is?

March 4, 2020, 7:44 am
$

In today's openSUSE announcment
https://news.opensuse.org/2020/03/04...in-Tumbleweed/

In the first paragraph it describes something I hadn't seen before and can't seem to find anything authoritative.

I don't know how reliable what I read on Reddit might be, from that it describes...
- RAID1C is typically followed by a number which describes the number of mirrored disks. In other words a standard RAID1 only mirrors one disk to another but something like RAID1C2 might mean that data is mirrored to 2 disks, not just one.
- If this is true, then this is supposedly to address the BTRFS issue supporting large arrays where the parity bit can be corrupted. Mirroring doesn't utilize a parity bit, and would support replicating data to as many mirrors as one might wish. It's not the same as RAID5/6, but it is an interesting different approach to disk fault tolerance.

This is apparently something very new so people should be careful about this new technology, but it has promise particularly if it's an iteration of widely used and reliable technology and not a major leap into the unknown.
In any case, even if it's newly available in the latest TW and possibly 15.2 kernels, documentation will need to be available if not guides and blogging before anyone could know how to set up and maintain (unless it just suddenly shows up in the BTRFS RAID management).

Just for reference,
I collected some good links for anyone who wants to implement BTRFS RAID (and BTRFS in general) in my openSUSE Wiki

Hi , I am a bit at a loss. In the past when I installed Samba it somehow worked . "Somehow" well I do not exactly know what I am doing in the network arena.

Anyway Samba .NOW.. just did not want to work . ...I must admit I do not know how to set up the Firewall !!!!!!

I tried to follow what has been written at the top of the forum entries ... no success

If somebody know a step by step config of Samba AND the firewall .... that would be much appreciated

... and what are the hardware requirements .... router etc


thanks and best regards

TUMBLEWEED Samba AD DC won't start - Looks like KDC is crashing.

March 4, 2020, 6:27 pm
$

0
On or about Mar. 1, there appears to have been an update to Samba 4 and/or it's required Kerberos packages. Unfortunately, since then my domain controllers won't come up. It looks like the KDC is choking on something. Below are the log message I'm getting in /var/log/warn when I "systemctl restart samba-ad-dc".

The CONNECTION_REFUSED appears to be related to the DCE endpoint mapper service, but I'd guess if the KDC doesn't come up properly, a lot of other stuff won't either. Oddly enough, the named/bind_dlz combination is working. But I can't authenticate to the domain any more. (obviously - no kdc)

There is also a message about DEPRECATED enctype that appeared starting Mar. 1.

I have no idea myself what's going on, though.

Anyone have any ideas?

Thanks!

TUMBLEWEED Request help trouble-shooting boot fail on mature system

March 4, 2020, 6:46 pm

Last thing I did before boot fail was Ctrl-Alt-Del out of boot process because I missed my first chance to re-direct the motherboard to boot from USB. So I did that, then next time I tried to boot the main SSD I ended with "You are in emergency mode..." Fortunately, the USB stick in question is a backup system, so I'm not in too bad a situation, plus I have a separate home partition that'll preserve everything important if I have to re-install. However, the btrfs root partition doesn't seem corrupted, as I can explore it when I boot from USB. What I don't know is what files to check for corruption.

I've used linux for years but never had occasion to check logs; "journalctl -xb" from the emergency mode prompt yields a nearly 3k lines that mostly look fine, ending with "The unit plymouth-start.service has successfully enetered the dead state."

About 30 lines prior, it says "Failed to get new runlevel, utmp update skipped."

If anyone has experience fixing a problem of this nature, is it easier to just reinstall? And if not, where do I find the file that journalctl reads, and what should I ^F search for to explain where the hiccup is?

I normally tackle issues like this by searching for answers already given rather than asking for new ones, but I do that with an error message of some kind, and in this case I don't have any unique terms to search for, so thanks for any pointers you can offer.

Witam,

Mam ogromny problem z openSuse Leap 15.1. Zainstalowałem go sobie na laptopie Huawei matebook 13 (2019), hybryda intel/nvidia i niby wszystko działa dobrze, poza tym że, niestety laptop piekielnie się grzeje. Taki problem nie występuje ani na Win 10 ani Manjaro Linux ani na Ubuntu 19.10.
Co jest z tym suse że robi mi piekarnik z laptopa? Próbowałem aktualizować kernel, plasme zaktualizowałem do 5.18, wyłączałem indeksowaniee plików w KDE< potem zmieniłem DE z ciekawości na GNOME i nadal to samo. Nic nie pomaga.
Ten OS po prostu tak ma? Na komputerze naprawdę,może nie być zupełnie nic uruchomione, żadna aplikacja a on się grzeje i wentylatory chodzą jak szalone.

Może ktoś wie jak to naprawić. W innym wypadku trzeba będzie wracać do Manjaro i może poczekać na Ubuntu 20.04, a szkoda bo szukałem stabilnego distro i suse mi się bardzo spodobało no ale te grzanie go dyskwalifikuje.

TUMBLEWEED 4k monitor at 30 Hz max refresh rate

Hi everyone,

I have a thinkpad x395 with an AMD Vega 8 video card and an external (HDMI-connected) 4k-capable monitor.
Problem is that at the max resolution (3840x2160), I'm only getting a 30 Hz refresh rate.

The issue is not with the laptop or the cable because running Windows on the same setup gives me 60Hz no problem.

Доброго времени суток.
Это не вопрос. Просто оставлю это здесь, ибо искал почему же ничег оне работает недлю, и нашёл чисто случайно, там, где ни в одном мануале не написано, что может быть проблема.
Преамбула: нужна доменная регистрация систем. Есть сервак в LEAP 15.1. Есть куча Убунтовских машин.
Мануалов - полно. Решений - полно. Но ничег оне помогало - Invalid Credentials и всё тут. Пробовал с клиента отпралять пароли и в открытом виде, и в md5, и в sha256/512 - без толку. Вообще.На сервере ввожу - входит. На клиенте - getent показывает информацию, ldapsearch показывает, что есть пользователи, но su - $ldap_user_name не проходит и всё тут.
Оказывается: Открываем Yast2 -> Users -> Expert Options -> Password Encryption. DES! Не md5, не sha256, а DES... Переставляем в нужную нам - и всё работает.
Даже в официальной документации к LEAP15.1 этого нет. Кстати официальная документация призывает пользоваться тем, чего нет в репозиториях o_O
Вам нужно установить dir389 и вот этими 3-я командами вы можете его настроить. А вот и нет. Нет этих команд после установки... Всё руками(

Доброго времени суток.
Есть странный, может быть, вопрос но как сделать так, чтобы машина взяла, примонтировала NFS раздел как /var/lib/docker и докер смог запуститься?
Примонтировать - не проблема, но там докер не запускается, ибо говорит, что не может сделать chmod на эту папку.
Система - виртуалка. Место в ней не так уж и много, чтобы держать много образов. Нужен болшой раздел. Большой раздел есть на сервере, он расшарен по NFS.
Мануалы говорят - монтируйте и всё работает. Но как-то что-то не так...
Пробовал делать права у папки 777
Code:
chown nobody:nobody
, пробовал
Code:
chown root:root
- не помогает.
