| cengique | Sarnold We got it by running microstack v 218 there is now a working control/compute node setup | 00:03 |
|---|---|---|
| sarnold | cengique: oh sweet :D now you get to work on whatever it was you were interested in doing in the first place, if you can still remember it :) | 00:05 |
| tds | TJ-: do you have v6 forwarding enabled? | 00:22 |
| TJ- | tds: yeah --- this is the weird part; all the usual bits are there, but the host doesn't do anything with the neighbour discovery broadcasts | 00:25 |
| TJ- | tds: just to be sure I'm not going loopey - proxy_ndp =1 on the 'upstream' interface (in my case wlp4s0) is the correct i/d to enable it on? | 00:27 |
| TJ- | this is the interface receiving the NS broadcasts | 00:27 |
| tds | yes | 00:27 |
| tds | you'll need to make sure you have the weird forwarding sysctl enabled there as well | 00:27 |
| TJ- | tds: yes: /proc/sys/net/ipv6/conf/wlp4s0/forwarding:1 | 00:28 |
| TJ- | tds: could this need mc_forwarding too? | 00:28 |
| tds | i don't think so | 00:28 |
| tds | you're not throwing away the NSes with nft/ip6tables or similar? | 00:29 |
| TJ- | tds: no - nothing in ip6tables except 'ACCEPT' inc. policies on the chains | 00:29 |
| TJ- | tds: in case it gives a clue - I noticed the entry in the proxy table is removed by something a while after I add it (maybe 5-10 minutes) - maybe that is normal | 00:33 |
| tds | TJ-: might be interesting to try testing inside the machine, or something like that | 00:40 |
| tds | eg bring up a veth pair between that and another netns, and try proxy ndp over that | 00:40 |
| TJ- | tds: hmmm, good idea | 00:40 |
| tds | (fwiw, testing on a 20.04 box here, proxy ndp works ok between two netnses) | 00:41 |
| TJ- | tds: hmmm, maybe I'm setting it up incorrectly. Just tried creating 'test1' adding global IPv6 addresses in a /64 from our prefix. Can ping in and out host<>netns (as with the libvirt guest) but remote (gateway router) NS's not getting a reply from my laptop | 01:07 |
| tds | so what if you set the host to proxy ndp an extra address in that /64, does test1 get replies to NSes? | 01:08 |
| TJ- | oh hang on, I forgot on this one to add a specific proxy-ed address | 01:09 |
| TJ- | tds: ahhh, got it for the netns. Had to add the proxy address and recall to re-add the host's default route to the gateway | 01:13 |
| TJ- | tds: and now it works!! | 01:16 |
| TJ- | tds: I think I was being messed about by doing this with NetworkManager managing the wlp4s0 interface and removing settings behind my back, such as the ipv6 default route | 01:17 |
| benl90 | Hello, I need some help. I use netplan on 18.04.5 and for about 4 month no problem with resolving the DNS, but suddenly yesterday the same config won't run and nslookup won't work, cause massive queue of email, for now I only can solve domain via overwriting /etc/resolve.conf which always change everytime, I never encounter this and this's really strange. any help is appriciated. Thanks | 05:37 |

| lordievader | Good morning | 06:24 |
| lordievader | benl90: What issues are you seeing exactly? | 06:25 |
| lordievader | Timeouts, actual errors, something else? | 06:25 |
| benl90 | lordievader, nah It's timeout. But somewhat strange using systemd/resolve.conf it works,using netplan it don't | 11:30 |
| lordievader | Is netplan writing different resolvers to /etc/resolv.conf? | 11:31 |
| mgedmin | netplan is not touching /etc/resolv.conf; netplan generates configuration files either for NetworkManager or for systemd-networkd | 11:41 |
| benl90 | mgedmin, nah That's what I know, but when I sudo systemd-resolve --status it doesn't have any DNS record. It's strange. But if I put "DNS=1.1.1.1 8.8.8.8" at /etc/systemd/resolve.conf it works. | 13:35 |
| lordievader | benl90: What are the contents of `/etc/resolv.conf` when you get the timeouts? | 14:17 |

| BC64 | Is this an ok place to ask questions about microk8s, MaaS, Juju, etc? | 22:11 |
| powersj | BC64, there are separate channels for maas and juju, but you might get what you are looking for here | 22:13 |
| BC64 | I'm trying to decide between microk8s and k3s for use in a small production cluster. I want to deploy Rancher on this cluster to deploy Kubernetes on a separate OpenStack cluster deployed using MaaS and Juju. | 22:17 |
| BC64 | As I typed that, I'm trying to figure out why I wouldn't just use Juju to deploy the Kubernetes cluster on OpenStack... | 22:18 |
| BC64 | I really like Rancher's GUI for the kube-illiterate | 22:19 |
