| syoc | I see that "netplan try" uses return code 0 even if it fails to apply the config? Are there any tricks to do an automatic sanity check for a netplan config? | 10:57 |
| slyon | syoc: You should be able to call "/lib/netplan/generate ./your-config.yaml", this will try to parse the config and show any parsing errors. Call this as non-root (without sudo), so it cannot actually write/generate any config files. | 11:01 |
| slyon | this is not an officially supported way, but should work. | 11:01 |
| syoc | slyon thanks a bunch! | 11:08 |
| syoc | well it errors out on a faulty config, but it also errors out on a correct config when I'm not using sudo (which makes complete sense). Was looking for something to use in conjunction with https://docs.ansible.com/ansible/latest/collections/ansible/builtin/template_module.html#parameter-validate | 11:11 |
| syoc | so it needs to return 0 | 11:12 |
| slyon | unfortunately there is currently no official way to check the config. If you're fine with it generating the config files in /run/systemd/... /run/NetworkManager/... you could run it with "sudo" | 11:14 |
| slyon | or prepare a temp root-dir and make use of the "generate --root-dir" option to validate the configs | 11:21 |
| Lucas8037 | hello. I'm trying to change the MAC address for a USB WiFi dongle thru netplan, running Ubuntu 20.04. | 16:31 |
| Lucas8037 | am using networkd as renderer, and under `wifis:` key, under my device `wlx...`, I added `macaddress:` with the desired MAC. | 16:32 |
| Lucas8037 | this does generate a .link file in /run/systemd/network/10-netplan-$blah with `MACAddress=` to the right value under `[Link]`, and yet it's being ignored | 16:32 |
| Lucas8037 | anyone has any clue why this isn't working? | 16:33 |
| Lucas8037 | `udevadm test-builtin net_setup_link /sys/class/net/$dev` does show that the generated file is being sourced, together with `/usr/lib/systemd/{99-default,73-usb-net-by-mac}.link` | 16:34 |
| Lucas8037 | the order in which files are sourced is 99, 73, 10 | 16:35 |
| Lucas8037 | 99 includes a somewhat sketchy `MACAddressPolicy=persistent`, which I feel is quite probably the one to blame | 16:36 |
