[opensuse] Need help with a broken network stack of Leap 42.3
The user contacted me yesterday alarmed saying: I just did some updates (days ago), at the end of the session I did shutdown. Now after a few days when I want to use the PC I have no network. I am only able to give advice via the phone, so all is quite complicated, user has a very low preparation in IT, so is easily "emotionally exhausted" and even easier frustrated. Therefore, less is more when it comes to “trial and error”. So what I did find (and do not really understand). Hardware: system is a ASUS M5A97 EVO R2.0 and has as eth a: Realtek 8111F Gigabit LAN controller Prior to the incident the card was recognized flawlessly. Manual: https://dlcdnets.asus.com/pub/ASUS/mb/SocketAM3+/M5A97-EVO_R2.0/ E8045_M5A97_EVO_R20_V2_WEB.pdf The system has a Wlan card and a eth card. But both seem to be out of funktion. It is branched to a Fritzbox AVM 7490 INT. There have been no changes in the router setting. User checked for network cables. So I can virtually exclude a router problem (has been rebooted for the sake of doing it) and the router resolves as it is possible to use a smartphone via WLAN to surf. The PC used networkmanager to handle the network. sudo ifup says correctly: handled by networkmanager skipping. O.K. In the network manager the connections are there, the settings correct. First observation: to my astonishment neither eth nor wlan is seen by the system (which raises in me the idea of an incomplete kernel update?). I tired to force a new /etc/resolv.conf , which worked by makes no difference, so it is not a question of address resolution either. So I went to yast and made the networkmanager deactivated and went to wicked. Now wicked says: there are three! eth cards, and one wlan card. two (eth0 configured) and wlan (non configured) the new one eth is not configured. Both eth cards have the same mac and the same brand so I am sure this is a double entry somewhere. I asked wicked to eliminate the "configured" eth and did let restart the network stack. Now I have just two cards revealed as expected. eth0 and wlan. The chipset is a Realtech card (Realtek 8111F) as expected. Now question: Have there been changes to the Realtech 8111F firmware in opensuse Leap recently? Is there any known breakage and how to deal with it. How can I get a meaningful dmesg (I do not know what error to search for) as in demsg I was not able to find (better the user for me) any message of failure. When I do try to set up the card in wicked it complains about the firmware and tells me to look for further information in dmesg. So I am stuck in the moment, as I do not understand what is wrong. It would be possible to do tethering with BT via the smartphone with the machine as BT is offered as networkstack in networkmanager. So I could try a zypper up to look for changes but given that the volume of these contracts are not endless, I would like to be more precise and just repaire the network and do the rest with the flat contract for dsl. If anybody has suggestion how to debug this, I would be really greatful. What else could be compromised to deactivate wlan and eth in networkmanager. It must be the firmware no? _________________________________________________________________ ________________________________________________________ Ihre E-Mail-Postf�cher sicher & zentral an einem Ort.

Okay, that's good. So problem has been isolated to the upgraded machine.
"seen by the system" ? how - lspci? in dmesg output?
What exactly does wicked say? Post the dmesg output to paste.o.o, if you can.

Are these not the symptoms seen by a couple of people recently and discussed on this list (or its opensuse-support twin). Some bug in an update that corrupted a network file and was cured by some magic network incantation to force it to rewrite the file? Sorry, I wasn't very interested and don't remember any more but hopefully somebody else will, or searching the recent archives might find the thread. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

So for my (very special case indeed, me myself do not have it in Leap so I am surprised..), I will follow the advice of Patrick and also take note of the pitfalls / failures. At latest Sunday we shall know if it is top or flop and nobody's advice will be "vane" because "poor soul "me, will try them all in order :-p Of course you will be given no credit(!) and I will prostrate myself to the user as "God on earth" in case it works, while I will wittily discharge all responsibilities on the forum if it fails. As usual no? Seriously thank you for the input. I have now a bit of hope to get that fixed. Thank you to all of you of course.

you should recover it as that is not one of the files cited.

Hmm, I wonder where it came from - here, /etc/netconfig is a file, not a directory. Either that has changed in the latest updates, or it might be the reason for the problems, as you cannot overwrite a directory with a file? In doubt you could try to remove the /etc/netconfig directory, and then run the magic 'netconfig -f' -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I would definitely look if there are some packages from non-standard repos.

sudo dmesg output yes. Astonishingly dmesg does not complain (for what reason ever) of missing firmware. If that would be a bug to be addressed. This on board eth chipset is common! (Nearly like nvidia with Thorwalds...Broadcom? f....Broadcom!)
Diffidult, I can maybe by "copy by hand written story like the old catholic monks!) - just with the gimmick "over the wire oral tradition" - no! Not that intended! obviously by phone (I am not THAT lucky with administration over all :-) ).
this is the biggest headache. I would rather for that user have hardware (in this case even old hardware) that works just "out of the box".

I have seen this after some upgrades.
You could do this to try ssh to the machine and do the testing yourself - but you may be unfortunate as me, because the phone gives me a 10.*.*.* address :-/
Maybe it is a card that needs firmware, and this fails to load or is missing the package. There was a firmware update recently: kernel-firmware-20190118-lp150.2.12.1.noarch The package is dated "Tue Feb 05 2019", I got it yesterday. So the obvious thing to try is to check what version does he have installed. If it is missing, install it. If it is this one, then install the previous version of that rpm, downloading on another machine, copy to usb stick, etc... -- Cheers / Saludos, Carlos E. R. (from 15.0 x86_64 at Telcontar)

I had to go back to the snapshot of 17.01.2019. I then converted it to default. Updated 500 mb of updates And the error was away. That to say: the error of wicked was wlan would give no error but eth0: "unable to configure the network card because the kernel device(eth0) is not present. This is mostly caused by missing firmware" So it appears that the device node was either not created correctly or the firmware was not in sync on the update mirror (by chance) and was not installed. In any case now it works. Thank you for the input, sorry for not being useful for finding the exact cause. _________________________________________________________________ ________________________________________________________ Ihre E-Mail-Postf�cher sicher & zentral an einem Ort.
