| new_guest_21 | Hi, quick question. I learnt recently that you can add ip routes to a custom table in firewall configuration (e.g. for WireGuard). I would like to know what characters are allowed in the table's name. Specifically, are alphanumerics and _ (underscore) allowed, or is it just numbers? (I've seen quite a few examples that use '1234' and '123' as table | 03:21 |
|---|---|---|
| new_guest_21 | names.) | 03:21 |
| new_guest_21 | E.g. command to give you an idea of what the 'table name' is that I'm referring to: `ip rule add iif wg0 table 123` | 03:21 |

| new_guest_21 | Ah, shoot. That was a dumb question considering there are default tables named 'default' and 'main'. :P | 03:38 |
| new_guest_21 | Must rest now. | 03:38 |
| lordievader | Good morning | 06:05 |
| koeretwqa | hi! i have a problem with setting up ufw on a diskless client running ubuntu server via NFS. whenever I enable UFW the system hangs because there must be some rule which is preventing system to get NFS packets from the NFS server. If I set DEFAULT_INPUT_POLICY to ACCEPT, then it works ok (but not something I'd desire). I tried all possible rules | 08:52 |
| koeretwqa | already to even allow all traffic from local network, but it still hangs the system... I would really appreciate any tip that would led me into the right direction... Thanks! | 08:52 |

| atjb | Hello - please could I ask for help installing a Linux Image package | 18:20 |
| atjb | I'm following a tutorial to run an ubuntu-KVM | 18:20 |
| atjb | And windows inside of it - https://medium.com/axon-technologies/installing-a-windows-virtual-machine-in-a-linux-docker-container-c78e4c3f9ba1 | 18:21 |
| atjb | At step 7 I'm getting an 'unable to find package' when I try to run apt-get install | 18:21 |
| atjb | The result of my $(name -r) is 5.4.0-88-generic - so I guess I'm looking for something else that will work that I can install instead? | 18:23 |
| pycurious | anyone has any experience with cors problem in nginx with python servers - https://dpaste.org/8Nvj ? I could use some help. Thanks. | 18:28 |
| sarnold | atjb: that feels pretty strange.. I didn't think the containers would be able to load kernel modules | 18:28 |
| atjb | It's the first time I've tried the tutorial - but it makes sense. In my experience, containers run pretty much anything inside them | 18:29 |
| atjb | But then again - I'm a novice | 18:29 |
| atjb | Ok - I've done a search and there's linux-image-5.4.0-87-generic & linux-image-5.4.0-89-generic - Signed kernel image generic available | 18:42 |
| atjb | uName on my build is 5.4.0-88-generic | 18:43 |
| atjb | Should I go for one version before or after? | 18:44 |
| atjb | I can't imagine it'll make much difference? | 18:44 |
| sarnold | it's probably worth rebooting into the newer kernel | 18:45 |
| sarnold | though I think we're doing kernel updates today, I'm not sure if those are out the door yet or not | 18:45 |
| atjb | Ok - fair enough, I'm just going to run with it | 18:48 |
| atjb | It's a learning exercise so no worries if it fails :) | 18:48 |
| TJ- | why put a VM hypervisor inside a docker container? That does seem extremely silly | 19:00 |
| sarnold | that was my first thought too, but I realized I don't know off-hand how to do the "differential disks" kind of thing in libvirt and this guide knows a way to not bother learning it :) | 19:03 |
| TJ- | differential disks? | 19:22 |
| TJ- | Isn't that what we have on our tractors!? | 19:22 |
| sarnold | dunno how else to say "let ten instances all share a qcow2 or zfs dataset and only write their own changes" | 19:22 |
| sarnold | lol | 19:23 |
| * genii makes vroom vroom sounds in the corner | 19:23 | |
| TJ- | genii: more of a constant roar if you please :) | 19:23 |
| TJ- | sarnold: looks simple to do for me at least; LVM snapshots | 19:26 |
| sarnold | TJ-: ah I never got the hang of lvm :) | 19:27 |
| TJ- | it's SO simple and flexible :) | 19:27 |
| sarnold | I think it's something that would just happen if you use zvols backing storage but I've not actually tried it myself.. | 19:27 |
| TJ- | pvcreate /dev/sda1; vgcreate VG /dev/sda1; lvcreate -n VM-base -L 30G VG; ... lvcreate --snapshot --size 1G --name snap01 VG/VM-base | 19:31 |
| TJ- | and of course the space can be thin-provisioned and images RAIDed and shared over iSCSI | 19:33 |
| sdeziel | qcow2 files can have backing files and possibly backing device (never tested the later). I'd be curious to have a qcow2 "delta" file backed by a base zvol ;) | 19:41 |
| atjb | I guess I'm just learning, so I dunno if putting a hypervisor inside. Docker container is a good idea or not | 19:41 |
| atjb | But at my stage I'm putting everything inside docker containers - so I guess I want to try this | 19:42 |
| atjb | I'd like a Remote Desktop, and this looks a good way to get one | 19:42 |

| patdk-lap | well the issue is, by the time you make kvm work inside a docker container, you have removed all security of the docker container, so it's pointless | 20:06 |
