 hexa | you really can achieve a lot with just networkd | 01:20:47 |
 Charles | seems that way | 01:21:06 |
|  relichunter joined the room. | 02:44:08 |
| Charles | hmm i'm getting
# ip route get $(dig AAAA google.com +short)
RTNETLINK answers: Network is unreachable
on the router machine again after rebooting it without any extra changes
| 03:00:47 |
| Charles | [root@green:~]# ip -6 route
2601:1c1:8400:a440::/64 dev br-lan proto kernel metric 256 expires 331268sec pref medium
unreachable 2601:1c1:8400:a440::/60 dev lo proto dhcp metric 1024 pref medium
fe80::/64 dev br-lan proto kernel metric 256 pref medium
fe80::/64 dev en-wan proto kernel metric 256 pref medium
this looks wrong, there's no non-ULA address for en-wan
| 03:08:34 |
| Charles | despite

| hexa | no default route | 03:09:10 |
| hexa | networkConfig.IPv6AcceptRA = true;
| 03:09:45 |
| hexa | on wan | 03:09:46 |
| Charles | i'll try that | 03:10:33 |
| Charles | yeah that was it, nice, thanks | 03:11:23 |
| Charles | so now that i've got ipv6 addresses for my machines, are the non-privacy-extensions ones stable for use in AAAA records for public DNS records? | 03:17:28 |
 mjm | depends how stable your prefix from your isp is | 03:18:07 |
| Charles | let's assume that it is | 03:18:15 |
| mjm | mine seems to change whenever they do non-trivial work | 03:18:18 |
| mjm | if you've got one that seems to match your mac address, that one should be stable | 03:19:41 |
| Charles | so for this:
2: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
link/ether 58:47:ca:71:7c:7d brd ff:ff:ff:ff:ff:ff

inet6 fe80::5a47:caff:fe71:7c7d/64 scope link proto kernel_ll
valid_lft forever preferred_lft forever
probably second inet6 line?
| 03:22:42 |
| mjm | yes, that one | 03:23:04 |
| Charles | ah the words following the address are documented here: https://man7.org/linux/man-pages/man8/ip-address.8.html#DESCRIPTION | 03:24:33 |
| Charles | mngtmpaddr seems to mean "this is the stable one" | 03:24:44 |
| Charles | or, imply it | 03:25:03 |
| mjm | the lack of "temporary" as well | 03:25:29 |
| Charles | thanks | 03:26:21 |
 uep | in particular, the "tmp" part of that is for "template" not "temporary" | 03:32:05 |
| Charles | ah, that makes more sense | 03:32:24 |
| uep | that's the template that the periodic privacy-addresses will be based on | 03:32:37 |
| uep | (which is why it's not used to create routes, the idea being that the other ones should be source for outbound connections) | 03:33:27 |
|  Frédéric Christ (back on 02.01.) changed their display name from Frédéric Christ (🧳 12.05. - 02.06.) to Frédéric Christ. | 07:02:13 |
 K900 | OK so here's an interesting question | 08:09:05 |
| K900 | I have the GPON modem stick thing | 08:09:12 |
