Indeed, dhcp4 mode still allows for IPv6 stateless autoconfiguration. -- You are receiving this mail because: You are on the CC list for the bug.

Also: what is default for leap these days? What do I go for? wicked? networkmanager? I never needed to really think about this kind of stuff. But this issue with this very system is still something different from the other system I started this bugreport with, which doesnt even get a public ipv6 assigned to begin with. Too much confusion for me without really knowing where or how to dig deeper. The actual (first) affected system that doesnt get the ipv6 assigned at all, is also remote for me, so I cant just mess or crash the whole machine, resulting for me in long distance travel and so on.

Hi Marius,

no we don't have anywhere in tests logic which make sure that only one of NetworkManager/wicked is up and running. We currently only checking that expected service is running.

after reviewing a bug and further discussion I can suggest such scenario :

1. systemctl status network.service - to get the one which treated by system as proper one 2. systemctl status wickedd.service wicked.service or systemctl status NetworkManager to check the one which suppose to be disabled is actually disabled.

Not only that it is disabled, but even more important, that it is not started.

Only thing which is not clear for me in which scenarios exactly we need to insert this check. For now on I will just extend scenario which checking that appropriate network service is running with this negative check that other one is not running. This mean that mostly this check will happen just after "normal" installation which less likely allow us to catch something.

This bug has high probability to be related to upgrade. Unfortunately for Leap upgrade not covered at all. Second mentioned bug #1122194 I find irrelevant for testing because it describes issue which happened due to 3d party rpm ( TeamViewer ). Do you have any other flow which we can cover in regard to this bug ?

Yes, we can't ensure this for third party RPMs as we don't install any, but prevent to add dependencies triggering a start in the RPMs we ship. I've already seen some ARM / Raspberry PI images where both wicked + NM were running + enabled. Also, there were bugs, that e.g. dhclient were still running after the switch from NetworkManager to wicked in YaST2, because a "systemctl stop NetworkManager.service" does not stop them due to the KillMode=process used by NetworkManager (to avoid it breaks remote-fs mounts on shutdown), e.g. https://bugzilla.suse.com/show_bug.cgi?id=895447. -- You are receiving this mail because: You are on the CC list for the bug.

But it is only wired/connected and using one single ethernet interface. Sometimes I use this machine for different things or add in more networking cards etc. I just checked, there is actually only a single onboard ethernet interface on this machine right now. That ipv4 forwarding/NAT stuff is probably leftovers from previous opensuse/leap editions this machine went through. I dont recall having problems with ipv4/ipv6 before with this machine and my basic ways to use opensuse. I have a kde desktop running on this machine and there is the yast online update automatic thingy every now and then in the tray area next to the clock, that installs updates/patches automatically every now and then on some kind of schedule. Pretty basic. Maybe that has got something to do with network manager or similar? -- You are receiving this mail because: You are on the CC list for the bug.
