Re: [opensuse-factory] dup –no-allow-vendor-change is now default

Posted by jpluimers on 2017/09/15

I totally missed this announcement 2 months ago:

after this update, zypper dup will default to –no-allow-vendor-change, whichhas been the recommended way for Tumbleweed for a long time now.

Source: Re: [opensuse-factory] dup –no-allow-vendor-change is now default

So Dominique was glad to “rub the salt” a bit (:

[WayBack/Archive.is] Dominique / DimStar‏ @DimStar Replying to @sysrich @jpluimers: for the record: –no-allow-vendor-change has become the default in Tumbleweed, see also http://dominique.leuenberger.net/blog/2017/06/review-of-the-week-201726/

It was documented at least on these places:

zypper errors on download.opensuse.org

Posted by jpluimers on 2017/09/13

If you see error message like below when performing zypper refresh or zypper dist-upgrade, then please inform the opensuse team (for instance Twitter or the #openSUSE-factory IRC channel) as this is part of the aftermath of the download.opensuse.org trouble that started last week.

Permission to access 'http://download.opensuse.org/ports/aarch64/tumbleweed/repo/oss/suse/setup/descr/appdata-icons.tar.gz' denied.

What happened to me with Raspberry Pi 3 and Tumbleweed is below and fixed because after I got in touch: the data restore had worked out OK, but the permissions didn’t.

I got there as the search for “Permission to access ‘http://download.opensuse.org/ports/aarch64/” got me to [WayBack] TUMBLEWEED Zypper Permission to access:

Unfortunately there was a catastrophic issue last week with the openSUSE download system (read: stuff is still broken and not all mirrors are fully functional).

A start job is running for dev-disk-by\… – Google Photos – Jeroen Wiert Pluimers – Google+

Posted by jpluimers on 2017/08/17

Reproduction of A start job is running for dev-disk-by... – Google Photos / Oops. Let’s see if I can reproduce it, as I think this is related: https://…

Reproducible steps below.

Related:

Tried tips from last link: fails as well

These are the modifications of the steps further on based on the last link above.

  1. After first boot, verify the WiFi drivers are there:

# rpm -qa | grep bcm43xx
bcm43xx-firmware-20170410-2.1.noarch

  1. After editing /etc/dracut.conf.d/raspberrypi_modules.conf, perform sudo mkinitrd without any -f
  2. After reboot, same error

Error result

At boot time:

A start job is running for dev-disk-by\…

After waiting:

Reproducible steps

  1. download (or a more recent one) from http://download.opensuse.org/repositories/devel:/ARM:/Factory:/Contrib:/RaspberryPi3/images/ :
  2. Install them on a MicroSD card
  3. Put in Raspberry Pi 3 and boot
  4. Get the IP address of the machine, then SSH into it (ssh root@ip-address, password linux)
  5. Follow the steps from [WayBack] openSUSE on Raspberry Pi 3: From Zero to Functional System in a Few Easy Steps – SUSE Blog | SUSE Communities to get WiFi working:
    1. Edit /etc/dracut.conf.d/raspberrypi_modules.conf and remove the sdhci-iproc from the first and # on the last line:From : 
      add_drivers+=" sdhci-iproc bcm2835-sdhost bcm2835_dma mmc_block dwc2 "
# Workaround for Wifi
#omit_drivers+=" sdhci-iproc"

      To :

      add_drivers+=" bcm2835-sdhost bcm2835_dma mmc_block dwc2 "
# Workaround for Wifi
omit_drivers+=" sdhci-iproc"
    2. Run these commands: 
      mkinitrd -f
reboot
    3. Check in Yast if wlan0 exists in System -> Network Settings, then assign an SSIS plus credentials to it
      1. Verify the list contains BCM43430 WLAN card
      2. Select it
      3. Click the Edit button
      4. Put the check mark next to Dynamic Address then select DHCP and the kind of DHCP (in my caseboth version 4 and 6)
      5. Click the Next button
      6. Keep Operating Mode as Managed
      7. Click the Scan Network button
      8. Select Network Name (ESSID) from the list
      9. Select Authentication Mode from the list
      10. Put the check mark for Key Input Type as Passphrase
      11. Enter the Encryption Key
      12. Click the Next button
      13. Click the OK button
      14. Quit Yast
      15. Wait a few moments, then very with ip a that wlan0 got an IP address
  6. Update the system: 
    zypper refresh
zypper dist-upgrade
  7. Reboot
  8. Wait for the error to occur on the HDMI screen (USB keyboard does not work there, so I cannot copy logs)

Gist log until 7. is below.

IRC chat transcript opensuse-factory

10:40am<wiertIs there anyone of the dev team here with a RPi3 that can see if my steps at https://wiert.me/2017/08/17/a-start-job-is-running-for-dev-disk-by-google-photos-jeroen-wiert-pluimers-google/ reproduce?
10:40amwiertTL;DR: Tumbleweed on Rpi3; enable WiFi according to site and forum instructions; zypper dist-upgrade; boot failure.
10:41amwiertwithout enabling WiFi everything is fine.
10:41amwiertspare RPi3s get in next week, so I’ll configure this one for my brother without WiFi for now.
10:43amfvogtHm, that guide can’t actually work that way (unless something changed significantly)
10:43amwiertit worked in the sense that it got WiFi working. it failed in the sense that you cannot upgrade any more (:
10:43amfvogtThe omit_drivers line removed the driver for the sd card controller, so it’s no surprise that it doesn’t boot anymore. It needs a different device tree
10:44amfvogtI guess you upgraded the kernel + DT? You must not do that
10:44amwiertfunny as after the mkinitrd, a reboot went fine.
10:44amwiertit’s only that after a zypper dup it fails.
10:44ammnowak__DimStar, I wan’t $$ only on Windows, I should not have to re-define $prompt_sign. I guess I need to move the second $prompt_sign to the if-clause below
10:45amfvogtwiert: Ah, so it ships with a WiFi enabled DT + Kernel with the TW image
10:45amfvogtIf you zypper dup then, it’ll switch to the DT + Kernel from plain TW, breaking everything
10:46amwiertWhat’s DT?
10:46amwiertdriver-tree?
10:46amfvogtClose, device-tree
10:46amwiert(that gist has all the steps I performed)
10:46amfvogtIt contains the assignment of memory and other HW resources to each other and drivers
10:47amfvogtwiert: “dtb-broadcom  obs://build.opensuse.org/devel:ARM -> openSUSE”
10:47amfvogtThat’s most likely the issue
10:48amfvogtYou can recover from that by downloading the right .dtb file and putting it on the sd card manually
10:48amfvogtAlternatively, the u-boot embedded one should still work, so you can delete the DT on the SD and it should boot again (with some missing peripherals though)
10:51amwiertI’ve already put a fresh disk image on it and I’m in the midst of configuring it for my brother (he’s mentally retarded and I’m putting it behind his TV so he can view his agenda electronically to see if that gives him more stability in organising his life; I need to be at his place in 2 hours)
11:27amwiert@fvogt: I will add this part of the IRC chat to that blog post and try to get your suggestions done when the spare RPI3s get in.

Some potential anti-virus and -malware tools for OpenSuSE Tumbleweed

Posted by jpluimers on 2017/07/31

I could not find many potential anti-virus and -malware tools for OpenSuSE Tumbleweed despite they would be useful not only for non-Linux clients like Windows and Mac OS X.

These I found:

Reverse ssh tunnel between two linux boxes to allow RDP traffic over port 3389

Posted by jpluimers on 2017/06/12

You know the drill: site that limits incoming traffic and has painful VPN. Luckily this time outgoing ssh traffic on port 22 was allowed (because they do SFTP which is SSH File Transfer).

Since I’ve outside Linux boxes and could run a Linux VM there (all Tumbleweed based), this allowed me to do a reverse SSH tunnel. Those are always a bit confusing, but this set of drawings really helps: What’s ssh port forwarding and what’s the difference between ssh local and remote port forwarding – Unix & Linux Stack Exchange [WayBack].

Which brings me to a statement like this:

ssh -o "ExitOnForwardFailure yes" -R :3389:192.168.199.114:3389 -p 33322 93.184.216.34

That didn’t work: a remote machine could not RDP to port 3389, but a local telnet localhost 3389 would. The reason is that by default sshd binds a remote port to the local address only and not the wildcard addres.

So you have to open up the remote config a bit: at least /etc/sshd_config and most likely also your firewall.
