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