Gather them running the save_y2logs command. See https://en.opensuse.org/openSUSE:Report_a_YaST_bug for more information. Thanks! Created attachment 815757 [details] YaST2 logs > could you also attach the YaST logs? Attached. Thank you Richard. I don't see anything weird in the logs. Even more, I installed a fresh Leap 15.1 and it works as expected.

I don't think so. I have exactly the same in the Leap 15.1 in which I did the test. I am going to add a NEEDINFO for Michal, and wait for his conclusion to see if there is something wrong in the YaST side. (In reply to Richard Bos from comment #6) > When I execute your "sysctl -a | grep disable_ipv6" command: > > My output is: > # sysctl -a | grep disable_ipv6 > net.ipv6.conf.all.disable_ipv6 = 1 > net.ipv6.conf.default.disable_ipv6 = 1 > net.ipv6.conf.eth0.disable_ipv6 = 0 <<<<<< this should be a problem. It overwrites global setup (.all.disable_ipv6) by per interface setup (eth0 in this case). Question is where it comes from because yast do not touch this per interface variables. Could you try a "hotfix": /usr/sbin/sysctl -w net.ipv6.conf.eth0.disable_ipv6=1 and check whether it survives reboot to see if it is configured by some other part of your system? > net.ipv6.conf.lo.disable_ipv6 = 1 > > > I checked my settings again and "enable ipv6" is unchecked. > (and IPv6 is thus present) > > In the log I find: > > 2019-08-14 06:23:35 <3> <system> (6198) [ag_udev_persistent] OPEN_FAILED > opening /etc/udev/rules.d/79-yast2-drivers.rules failed: No such file or > directory > > 2019-08-14 06:23:35 <1> <system>(6159) [Ruby] modules/LanItems.rb:1134 > Ops.get called on nil. > 2019-08-14 06:23:35 <1> <system>(6159) [Ruby] modules/LanItems.rb:1133 Index > 1 is out of array size > 2019-08-14 06:23:35 <1> <system>(6159) [Ruby] modules/LanItems.rb:1131 Index > 1 is out of array size > > The code does not seems to be happy... Usually not a problem.

No. It just means that you don't use per interface route files. Again just info. (In reply to Richard Bos from comment #7) > BTW: the logfile used is: y2log-1.gz It is a rotated logfile. Usually contains e.g. logs from installation or old logs which are not accurate anymore. what we need is at least /var/log/YaST2/y2log or (better) result of save_y2logs command as pointed in Comment#3 - it gathers also some other logs and stores a pieces of configuration state which help us to debug the issue. Sorry, I've been busy replacing a disk.... I now checked the status and look: # sysctl -a | grep disable_ipv6 net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.eth0.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1 Lo and behold: # ip a no IPv6 I did _not_ make changes.... Well check next reboot as well, and see what that gives. @Richard, Any updates on this? Multiple reboots, all of them without IPv6 (as configured). I suspect that the disk repair solved the issue (sounds strange, but it seems so). (In reply to Richard Bos from comment #13) > Multiple reboots, all of them without IPv6 (as configured). > > I suspect that the disk repair solved the issue (sounds strange, but it > seems so). Indeed, it sounds quite strange. At this point, I think we can do nothing more than close the report as INVALID. Thank you so much for your collaboration, Richard. |
When not enabling IPv6 in "yast network", there are still IPv6 addresses listed: # ip a ... 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether e0:cb:4e:1b:ba:33 brd ff:ff:ff:ff:ff:ff inet 192.168.x.y/24 brd 192.168.x.y scope global noprefixroute dynamic eth0 valid_lft 862289sec preferred_lft 862289sec inet6 <hex address-1>/64 scope global temporary dynamic valid_lft 5127sec preferred_lft 3361sec inet6 <hex address-2>/64 scope global mngtmpaddr noprefixroute dynamic valid_lft 5127sec preferred_lft 3361sec inet6 <hex address-3>/64 scope link noprefixroute valid_lft forever preferred_lft forever This is after (multiple reboots). Yast network has: Global Options tab: Network Setup Method: Wicked Service [ ] Enable IPv6 ===== Initially 'enable IPv6' was checked (enabled). I unchecked it. After unchecking, rebooted. As there were still IPv6 addresses listed, I enabled and disabled the setting again, no change. The IPv6 addresses are still listed. Looks 'enable IPv6' has no impact and IPv6 is still configured, check please.
