Hi,
try enable level=TRACE logging. See https://cgit.freedesktop.org/Ne tw or kManager/NetworkManager/tree/contrib/fedora/rpm/NetworkManager.conf for hints how to do that. Then look at the logfile or send it.Looked at it. Not sure I'm really seeing why the "failure changing link: failure 22 (Invalid argument)". The whole log can be found at: http://brian.interlinx.bc.ca/NetworkManager.debug
it fails setting the token. platform-linux: link: change 2: token: set IPv6 address generation token to ::2 Probably because kernel does in inet6_set_iftoken(): »·······if (!token) »·······»·······return -EINVAL; »·······if (dev->flags & (IFF_LOOPBACK | IFF_NOARP)) »·······»·······return -EINVAL; »·······if (!ipv6_accept_ra(idev)) »·······»·······return -EINVAL; »·······if (idev->cnf.rtr_solicits == 0) »·······»·······return -EINVAL; either kernel should allow it, or NM should not try to set it. (btw, why do you want to configure the token?)
Unrelatedly I did notice: Mar 25 08:46:53 server.interlinx.bc.ca NetworkManager[976]: <debug> [1521982013.8717] dhcp6 (enp2s0): running: /sbin/dhclient -d -q -6 -N -sf /usr/libexec/nm-dhcp-helper -pf /var/run/dhclient6-enp2s0.pid -lf /var/lib/NetworkManager/dhclient6-90f5409c-bd23-48f2-b03f- 325333198827- enp2s0.lease -cf /var/lib/NetworkManager/dhclient6-enp2s0.conf enp2s0 That's a waste of time. There is no DHCP6 server in this network and if there were, it would be this machine. How can I disable this waste of time?
ndisc[0x555d606ee200,"enp2s0"]: dhcp-level managed Your router says there is a DHCPv6 server around. Don't configure your network that way, if it's not the case.
Ultimately, nm-online did not return until 08:47:39 which is 1:34 after NetworkManager started. I think eliminating that dhclient run would go a long way toward that.
best, Thomas
