[09:18] <egon96> nmcli general shows reduced connectivity but my netplan has ip4v and ipv6 addreses. Why is the connectivity reduced to LAN? (But I have ssh connections)
[10:07] <egon96> @sil2100 @slyon I asked: [10:18:40 AM] <egon96> nmcli general shows reduced connectivity but my netplan has ip4v and ipv6 addreses. Why is the connectivity reduced to LAN? (But I have ssh connections)

[10:15] <slyon> egon96: oh I must have missed that. what do you mean by "reduced connectivity"? How does you netplan YAML look like?
[10:25] <egon96> This is my netplan:network:

[10:28] <egon96> ping ipv4 functions, ping6 ipv6 gets no answers
[10:32] <slyon> according to nmcli's manpage the "CONNECTIVITY: begrenzt" (i.e. "limited") means: "the host is connected to a network, but it has no access to the Internet."
[10:33] <slyon> is fe80::1 an actual IP6 gateway? that IP looks odd to me... its a link-local address, but not derived from a MAC.
[10:37] <slyon> did you assing this IP to your routers interfaces manually/statically?
[10:38] <slyon> can you ping6 fe80::1?
[10:40] <egon96> no
[10:42] <egon96> The gateway address is told me from my vserver's provider
[10:44] <slyon> okay. Can you show the output of "nmcli dev ens3" and or "ip addr ens3"? To check if you have a link-local IP6 assigned to your interface?
[10:45] <slyon> You might be able to force this by using netplan's "link-local: [ ipv6 ]" setting
[10:45] <slyon> maybe you can't ping the gateway because there is not link-local address assigned to ens3
[11:06] <egon66> My laptop lost power so I am disrupted. I have to restore my environment
[11:06] <slyon> re posting my last messages:

[11:52] <slyon> well it looks like you have an actual ipv6 link-local address: fe80::8467:b6ff:fe38:6899/64. You should be able to ping your gateway (fe80::1) then, if that exists..
[12:02] <slyon> does this work: ping6 fe80::1%ens3 ?
[13:56] <egon66> yes, it works:

[15:19] <egon66> slyon (I had  to do other things.) Have you seen my message that ping6 with %ens3 works? What does that mean? What should I do? (In netplan?)
[15:19] <slyon> egon66: ah! that's good news. It means the gateway6 is working
[15:20] <slyon> I'm still wondering why it can't reach the internet though... can you "ping6 2001:4860:4860::8888" (i.e. the IPv6 google DNS)
[15:21] <slyon> maybe it's a DNS issue after all, as there is not IPv6 DNS in you netplan config
[15:25] <egon66> ping6 with google-address say there is no service. Yes, this should be a nameserver problem.
[15:28] <slyon> what is the exact error message? If you cannot ping, then is must be something else than DNS, no?
[15:33] <egon66> The message:
[15:33] <egon66> thomas@thomasKVM:~$ ping6 2001:4860:4860:8888
[15:33] <egon66> ping6: 2001:4860:4860:8888: Der Name oder der Dienst ist nicht bekannt
[15:33] <egon66> thomas@thomasKVM:~$ ^C
[15:33] <egon66> thomas@thomasKVM:~$
[15:34] <egon66> Should I have a line with nameservers6 or so?
[15:35] <slyon> I have two ideas:
[15:35] <slyon> 1) define "gateway6: fe80::1%ens3" (not sure if this is supported by netplan)
[15:35] <slyon> 2) add "2001:4860:4860:8888" to the list of nameservers.addresses
[15:37] <egon66> I"ll try your ideas. Then you "ll hear from me. Thanks!
[15:58] <egon66> Second idea: I get:
[15:59] <egon66> Error in network definition: malformed address '2001:4860:4860:8888', must be X.X.X.X or X:X:X:X:X:X:X:X
[15:59] <egon66>         addresses: [85.214.20.141, "2001:4860:4860:8888"]
[16:12] <slyon> sorry, the google DNS is "2001:4860:4860::8888" (note the :: there)
[16:23] <egon66> This ping is correct.
[16:24] <egon66> But now the other way.
