| teward | for 18.04 servers, is it possible to roll custom nameservers with DHCP and ignore the DHCP assigned nameservers? | 15:24 |
| teward | i forget :P | 15:24 |
| teward | (this is for LXD containers which get DHCP'd network data) | 15:25 |
| lordcirth | teward, yes | 15:43 |
| lordcirth | teward, using netplan, you need dhcp4: true but dhcp4-overrides: use-dns: false | 15:44 |
| lordcirth | Assuming the docs are correct, haven't tried it | 15:45 |
| seveneleven | how can i configure a NIC to use vlan id 2 using ubuntu preseed? | 17:00 |
| lordcirth | seveneleven, the NIC is on a tagged port, and you need it to create a vlan2 interface and configure networking on that? | 17:01 |
| seveneleven | lordcirth, it's on an untagged vlan 2 port | 17:01 |
| seveneleven | lordcirth, so i should just configure pvid 2 on that port instead? | 17:01 |
| lordcirth | seveneleven, if it's untagged, why would you need to do anything different? | 17:02 |
| seveneleven | wait, let me rethink why it didn't work last time | 17:02 |
| seveneleven | ok i described it wrongly | 17:02 |
| seveneleven | it's a vm on a hypervisor, now the hypervisor is connected to a tagged vlan 2+3 port, last time i created a br.2 bond and got the vm working with an internet connection | 17:03 |
| lordcirth | seveneleven, so the hypervisor should expose an untagged port to the VM, and put it on vlan 2. | 17:04 |
| seveneleven | yeah | 17:04 |
| lordcirth | We do that with LXC containers at $WORK | 17:05 |
| seveneleven | i use libvirt kvm qemu | 17:05 |
| lordcirth | seveneleven, ok, so what problem are you having? | 17:06 |
| seveneleven | i wonder how I can configure br.2 in ubuntu's preseed | 17:06 |
| lordcirth | seveneleven, if the hypervisor is providing an untagged eth0, why would you need to? | 17:07 |
| seveneleven | hmm, not sure | 17:08 |
| seveneleven | last time I simply created a br0 bond, and got no route to WAN, once I created the br.2 explicitely it worked | 17:08 |
| seveneleven | thats why i thought i need it | 17:08 |
| lordcirth | seveneleven, then your hypervisor was passing in a tagged port. | 17:09 |
| seveneleven | hmm | 17:09 |
| seveneleven | lordcirth, i just checked and my hypervisor uses a bridge between the vm http://dpaste.com/0NB8V3S | 17:13 |
| lordcirth | seveneleven, ok, so what is br0 tied to? 'brctl show br0' | 17:13 |
| seveneleven | enp0s31f6, vnet1 and vnet2 | 17:14 |
| lordcirth | seveneleven, and enp0s31f6 is the tagged one with vlans 2+3, right? | 17:15 |
| seveneleven | yeah | 17:16 |
| lordcirth | seveneleven, so, br0 is tagged, and your VM's interface is therefore tagged. | 17:16 |
| seveneleven | enp0s31f6 is like eth0 | 17:16 |
| seveneleven | ohh gotcha | 17:16 |
| lordcirth | What you want is to create a enp0s31f6.2 interface on the host, which is untagged vlan2 | 17:16 |
| lordcirth | Then make a br2 that is tied to that, and put your VM on that. | 17:17 |
| seveneleven | oh that's clever | 17:17 |
| lordcirth | Our LXC servers essentially do this - I use Salt to generate the netplan configs for a list of vlan IDs, and we get a iface.422 tied to a br422, and make containers on br422, etc. | 17:18 |
| seveneleven | wow then you end up with many many interfaces | 17:18 |
| lordcirth | yeah, but, automation :P | 17:19 |
| seveneleven | im going to try that, but just out of curiousity, would it have been possible to configure ubuntu to br.2 via the preseed? i assume yes, but it's probably more complicated | 17:19 |
| lordcirth | It is probably possible, but I don't know how. | 17:20 |
| lordcirth | Well, you could drop a netplan file in, but that wouldn't get you networking in the installer. | 17:20 |
| seveneleven | mhmm | 17:25 |
| seveneleven | i keep it simple and stupid and try your solution :-) | 17:26 |
| seveneleven | yeah seems custom bonds are not really supported for ubuntu installer https://askubuntu.com/questions/528211/can-d-i-ubuntu-installer-configure-bond-vlan-and-second-network-interface-dur | 17:36 |
| seveneleven | lordcirth, should i configure an ip on the iface.422? | 17:53 |
| seveneleven | or just "create" it and configure the IP on the br422? | 17:53 |
| seveneleven | im using /etc/network/interfaces for configuration | 17:53 |
| lordcirth | seveneleven, you don't need an IP on the host side to have the VM work | 17:54 |
| seveneleven | mmhm | 17:54 |
| seveneleven | so I just add `auto enp0s31f6.2` and `auto br2` inside /etc/network/interfaces? | 17:55 |
| seveneleven | (and use brctl to add enp0s31f6.2 to br2) | 17:56 |
| lordcirth | seveneleven, this is what I have: https://gist.github.com/lordcirth/a4c3b71a0f6ec29be704a440ceb5961e | 18:00 |
| lordcirth | brctl is transient, you want it all in files. | 18:01 |
| seveneleven | aaah right, brctl forgets it after reboot | 18:01 |
| lordcirth | the vlan device needs to be explicitly tied to the interface, and the bridge to the vlan | 18:01 |
| anton4i3ke | Im seveneleven, seems like my network died after restarting its service hehe 😊 | 18:04 |
| lordcirth | anton4i3ke, it is easy to make a mistake when doing this | 18:05 |
| sarnold | anton4i3ke: you might have missed < lordcirth> the vlan device needs to be explicitly tied to the interface, and the bridge to the vla | 18:06 |
| anton4i3ke | Yeah | 18:09 |
| anton4i3ke | Going to troubleshoot now | 18:09 |
| sarnold | anton4i3ke: due note that it's entirely normal for all existing connections to an IP address to drop when you add a bridge to a NIC (or add a NIC to a bridge?) -- on linux the IP is associated with the *bridge*, not the nic.. | 18:12 |
| coreycb | jamespage: sahid: i think i have the remaining py2 drops done. once we get the RM bugs handled we should know for sure. | 18:13 |
| seven-eleven | lordcirth, hmm i dont get a route between the vm and the hypervisor | 19:27 |
| seven-eleven | how does your interfaces config look like on the vm? | 19:28 |
| lordcirth | seven-eleven, just eth0 as a static IP | 19:28 |
| seven-eleven | hmm i tried that | 19:28 |
| seven-eleven | i worry this is a libvirt issue | 19:28 |
| lordcirth | seven-eleven, can you pastebin your /etc/network/interfaces on the host? | 19:28 |
| seven-eleven | ok | 19:28 |
| seven-eleven | lordcirth, sorry i need a while, i have X running in the basement now, so i cant connect to the X remotely anymore, and i dont know what display manager i used so i cant stop it :D | 19:31 |
| lordcirth | seven-eleven, lol. you can kill X? | 19:31 |
| seven-eleven | i tried killall X | 19:31 |
| seven-eleven | i run `startx` in the basement | 19:31 |
| lordcirth | seven-eleven, killall Xorg | 19:32 |
| seven-eleven | let me try | 19:32 |
| seven-eleven | not found hmm | 19:32 |
| seven-eleven | i can just reboot, but im curious | 19:32 |
| seven-eleven | i reboot | 19:33 |
| seven-eleven | i cant pastebin because i dont have a connection, so I write it 1:1 http://dpaste.com/0R0RKCT | 19:38 |
| lordcirth | seven-eleven, is that the host or the guest? | 19:40 |
| seven-eleven | ah thats the guest | 19:40 |
| seven-eleven | a moment | 19:40 |
| seven-eleven | https://termbin.com/1ixi | 19:41 |
| seven-eleven | ohhh | 19:41 |
| seven-eleven | found the mistake! | 19:41 |
| seven-eleven | it's actually libvirt issue | 19:42 |
| seven-eleven | libvirt automatically adds vnet1 to br5, so now we have enp0s316.5 and vnet1 inside br5 | 19:42 |
| lordcirth | And you wanted 2? | 19:43 |
| seven-eleven | nope | 19:43 |
| lordcirth | I thought you wanted vlan 2, but there's no enp0s31f6.2. Was it 5 you wanted? | 19:44 |
| seven-eleven | ah, two interfaces dont matter regarding tagged vlan, would have to be two vlans inside br5 to be considered tagged? | 19:44 |
| seven-eleven | i wanted vlan 2 | 19:44 |
| seven-eleven | but the problem is if I set it to vlan 2 then br0.2 stops working | 19:44 |
| lordcirth | seven-eleven, if the switch port is tagged, it's tagged, even if there's only 1 vlan | 19:45 |
| seven-eleven | i had to delete enp0s31f6.2 to get my LAN back working | 19:45 |
| seven-eleven | gotcha | 19:45 |
| seven-eleven | so I need to get the vm to use vlan 2 | 19:45 |
| lordcirth | But the host also needs an IP on vlan 2? | 19:46 |
| seven-eleven | that means I have to remove br0.2, rewrite my iptables to source through br2 | 19:46 |
| seven-eleven | yes | 19:46 |
| seven-eleven | the host itself needs an ip | 19:46 |
| seven-eleven | i would add it to br2 right? | 19:46 |
| lordcirth | I would create a enp0s31f6.2, which is an untagged interface. Then tie it to 'br2'. Then set an IP for the host on br2, and attach the VM's eno3 to br2 as well | 19:47 |
| seven-eleven | so i would do something like http://dpaste.com/00YW181 ? | 19:47 |
| seven-eleven | ok i retry this :-) | 19:48 |
| seven-eleven | lordcirth, should I move br0.3 to enp0s31f6.3 respectively or leave it as br0.3? | 19:50 |
| seven-eleven | br0.3 is not used for guests, br0.3 goes directly to the WAN router | 19:50 |
| seven-eleven | br0.3 is tight via br0 to enp0s31f6 | 19:50 |
| seven-eleven | not sure if br0.3 can coexist with using enp0s31f6.2 | 19:51 |
| seven-eleven | i will just try | 19:51 |
| lordcirth | seven-eleven, the paste looks correct, assuming you use '2' instead of '5' and that the enp0s31f6.2 interface is also correct | 19:53 |
| seven-eleven | lordcirth, ok | 19:53 |
| seven-eleven | lordcirth, so i leave br0.3 tied to br0 | 19:54 |
| seven-eleven | and use now br2 | 19:54 |
| lordcirth | I am not sure how your network is set up for br0.3 | 19:54 |
| seven-eleven | br0.3 is in the subnet of my WAN router | 19:54 |
| seven-eleven | br0 is tied to eth0 | 19:55 |
| seven-eleven | br2 is now tied to eth0.2 | 19:55 |
| seven-eleven | lordcirth, works fine. now it's properly configured, so much easier to just configure eth0 on the guests, and makes auto installing easier | 20:49 |
| seven-eleven | thx! :-) | 20:49 |
| lordcirth | seven-eleven, great, you're welcome | 20:49 |
