[13:04] so, I've made some changes to my netplan configs and I'm having some warnings related to routing. here's the current configs and warnings: https://0bin.xyz/view/8950a048 [13:05] I really can't fugure it out [13:11] PeGaSuS, gateway6 is deprecated, you need to use 'routes' instead. There are some examples here https://netplan.io/examples [13:12] it seems you already uses it in your 99-he-tunnel.yaml [13:26] my problem is that I can't understan netplan routing in any way, though. I've been having this issue for almost one week and I can't really wrap my head about routing and other options [13:28] commands like `curl -6 https://nominatim.openstreetmap.org` or even `mtr -6 nominatim.openstreetmap.org` have no response whatsover [13:43] I've tried this: https://termbin.com/3sp0 [13:44] I cant understand this is no way.. I swear tto god [13:50] well, maybe if you provide the output of the command below someone might spot something [13:50] ip addr [13:50] ip link [13:50] ping6 nominatim.openstreetmap.org [13:50] tracepath -6 nominatim.openstreetmap.org [13:51] and ip route of course [13:56] https://0bin.xyz/view/26226a86 > the output for all of those commands. I had to stop tracepath after 25 attempts [14:02] and 'ip -6 route' as well, ip route will not show ipv6 routes... [14:05] I think I've broken my machine entirely. can't access it via SSH anymore and it doesn't answer to ping [14:06] now I need to figure out how to fix it from rescue boot [14:23] the `ip -6 route` output: https://0bin.xyz/view/27827d76 [14:24] I've merged the tunnel config with the default one: https://0bin.xyz/view/05d9a49a [14:25] I've tried to follow: https://netplan.io/examples#:~:text=dhcp%2Didentifier%3A%20mac-,Connecting%20an%20IP%20tunnel,-Tunnels%20allow%20an [14:31] is the tunnel working? can you ping the other side? [14:32] yes. I can ping the tunnel addresses perfectly from another machine [14:34] this is an example: https://0bin.xyz/view/b30b0069 [14:36] is the default route itself (2001:470:1f20:a::1) pingable? [14:37] I can also ping it from another machine, yes [14:38] well, it must be reachable from the machine you are working on [14:38] I can also ping it from the machine with the tunnel [14:40] fwiw, here's my tunnel: https://imgur.com/ku3EEiM.png [14:41] ok, at this point you will need to tcpdump the other end and confirm packets are going through [14:41] you might a routing problem there [14:42] you might have* [14:42] in this case it may be HE fault? [14:43] it's hard to tell, you need to check if the packets are going to the destination but never coming back for example [14:44] how would I do that? [14:44] as you can ping your default gw, I'd say the traffic is getting to the other side at least [14:45] you don't have access to the other end of the tunnel? [14:46] if you have access to another machine in another network that speaks ipv6 you can try to ping it from this host and check if the icmp packets are getting there [14:46] I can ping the machine from inside and outside it via IPv6 [14:47] the other end of the tunnel is Hurricane Electric (tunnelbroker.net) [14:51] I'm applying the tunnel on machine A. I can ping any IPv6 address that I see with `ip a` from inside and outside machine A. [14:52] I can use `curl -6 address` and `mtr -6 address` with some adresses but not with https://nominatim.openstreetmap.org, for example [14:53] how can I remove/disable a tunnel completely? [14:53] unfortunately I don't have ipv6 here to test it. Is this address pingable from this host? 2001:4860:4860::8888 [14:56] yees. I can ping it from machine A perfectly [15:00] hmm that's google DNS. So I don't know what's wrong with openstreetmap.org, but your configuration seems to be working fine then [15:14] I believe that's HE fault since, apparently, openstreetmap.org is hosted by HE [15:20] hosted or tunneled by HE* [15:36] if I remove a tunnel from the netplan config, I deconfigure it right? I mean, it's not used anymore, correct?
