RFC 2210 2304 fixed https://bugs.launchpad.net/bugs/1951586 [netplan WiFi country code / regulatory domain] #3537

jvonau · 2023-04-14T13:59:20Z

See url, don't need workaround netplan going forward

holta · 2023-04-14T14:01:10Z

Wow!

holta · 2023-04-14T14:05:24Z

Does this improvement apply to Ubuntu 22.10 and 23.04 exclusively?

(Never affected Ubuntu 22.04 and Mint 21 apparently?)

holta · 2023-04-14T14:18:24Z

PR #3078 added very useful context here:

iiab/roles/network/templates/hostapd/iiab-test-wifi.j2

Lines 25 to 28 in c9ed0a0

    
           # covers netplan's bugs workaround 
        
           # https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1862760

           # WiFi country code progress on arm64 OS's discussed on #3078

Is some of that still relevant? (Or should most of the above lines perhaps be trimmed?)

jvonau · 2023-04-15T00:24:42Z

Does this improvement apply to Ubuntu 22.10 and 23.04 exclusively?

Depends on if the netplan improvement made it into the other releases.

(Never affected Ubuntu 22.04 and Mint 21 apparently?)

Quite the opposite, those would be affected by the bug unless the fix is pushed to those releases. This change doesn't care about which release, if the country is set leave it alone otherwise doctor up the file.

holta · 2023-04-15T09:05:04Z

Does netplan.io version number matter?

Ubuntu 22.04.2 and Mint 21 (apt updated) show:

# apt list -a netplan.io
Listing... Done
netplan.io/jammy-updates,now 0.105-0ubuntu2~22.04.3 amd64 [installed,automatic]
netplan.io/jammy 0.104-0ubuntu2 amd64

Ubuntu 23.04 (apt updated) shows:

# apt list netplan.io
Listing... Done
netplan.io/lunar,now 0.106-0ubuntu3 amd64 [installed,automatic]

holta · 2023-04-15T09:33:54Z

Does netplan.io version number matter?

Which version of Ubuntu is most important to test if @EMG70 or others have time?

If so, what test sequence is most important?

(Would testing on an old 64-bit laptop possibly be sufficient?)

jvonau · 2023-04-15T19:06:58Z

All of the info is in the upstream ticket, grok that for the needed info.

holta · 2023-04-15T19:40:51Z

A short summary is needed for @EMG70 and/or others volunteering their time to test.

jvonau · 2023-04-15T20:03:45Z

A short summary is needed for @EMG70 and/or others volunteering their time to test.

Well testing netplan's networkd's wifi config would need to use the first boot config file mentioned but all you would be testing is a potential bug that is a bit tricky to uncover. In the current master there would be a potential to have duplicate country= lines within what becomes the wpa_supplicant config file within /run/netplan/

holta · 2023-04-15T20:13:52Z

Thanks for the explanation.

Hopefully netplan.io 0.107 & Ubuntu 23.10 are more understandable later this year — in preparation for Ubuntu 24.04 LTS in almost exactly 1 year.

jvonau · 2023-04-15T23:03:45Z

apt changelog netplan.io should be able to tell you what is in each revision.

holta · 2023-04-16T03:35:22Z

As @jvonau knows, but if others are trying to make sense of this...

https://github.com/canonical/netplan/releases indicates Country Code / Regulatory Domain became part of netplan's main branch on 2022-06-30, and a part of netplan 0.105 on 2022-08-18:

FWIW rpi-imager started to take taken advantage on 2022-07-31:

raspberrypi/rpi-imager@31252bf

PR set 'host_country_code' to value found in wpa_supplicant.conf [on Raspberry Pi OS only, deferring Ubuntu/Debian upstream issues] #3179

jvonau · 2023-04-16T11:29:20Z

The last commits should compliment 3179 finishing off WiFi country detection on all platforms.

holta · 2023-04-16T16:02:26Z

@EMG70 has very generously offered to help test.

If there are clear instructions, working with any specific Ubuntu that we recommend?

(But I'm not sure what's most important to test.)

The rpi-imager program changes reasonably often, but FYI https://ubuntu.com/tutorials/how-to-install-ubuntu-on-your-raspberry-pi#3-using-advanced-options helpfully shows a "Wireless LAN country" setting here, that @EMG70 might try with Ubuntu SERVER 23.04 after it's released Thursday: (2023-04-20)

Or maybe try the pre-release Beta here: https://releases.ubuntu.com/lunar/

holta · 2023-04-16T23:51:44Z

RasPiOS country code details are separate from this ticket, but not terribly far afield — so just FYI use Ctrl-F to see the 43 mentions of "country" on this page if necessary:

https://www.raspberrypi.com/documentation/computers/configuration.html

jvonau · 2023-04-17T01:47:16Z

Better pic of the country code setting:

EMG70 · 2023-04-17T12:58:06Z

I will try the pre-release beta in next two days then wait for Thursday release date and let you know.

holta · 2023-04-17T13:03:48Z

I will try the pre-release beta in next two days then wait for Thursday release date and let you know.

It's possible of course... that Ubuntu 23.04's Beta ends up being nearly identical to Thursday's final release.

EMG70 · 2023-04-19T20:36:20Z

@jvonau's suggestion above looks good, if in fact Admin Console did not quite get installed.

Do http://localhost and http://localhost/admin both work — loading in the Raspberry Pi 400's own browser — i.e. on the attached screen?

CLARIF... here's a foolproof way to verify Admin Console is installed... since this is a headless OS (Ubuntu Server 23.04 Beta) use a text browser (in any terminal/console on the Raspberry Pi 400) to try things like...
lynx http://localhost
lynx http://localhost/admin

Currently running iiab-network,should be done soon

All Good,Thanks.

jvonau · 2023-04-20T13:49:46Z

Some takeaways from all this:

Using imager's to set the wifi credentials results in the wired eth0 device not be enabled post install and gets placed under the LAN bridge.
Editing network-config preinstall of armU2304server or /etc/netplan/ post install can add in the missing eth0 definition.
Adding 'band: 2.4GHz' to the netplan wifi definition limits the wlan0 wifi client to 2.4 resulting in hotspot being usable when the 'ssid' is common on both 2.4/5GHz bands.

EMG70 · 2023-04-20T14:25:11Z

Good summary there Jerry ,easy to understand the test.

EMG70 · 2023-04-20T20:45:00Z

@jvonau ,Not sure this issue is related to this PR.
I have accidentally found out that if I connect my server to an ethernet cable and VPN is enabled post install, I can access iiab home page from any device connected to my Sky home router without hooking up via IIAB hotspot.
This happens across OS systems ,just tried on Debian 11 desktop,23.04 server and desktop ,same happens.
Can I assume devices are being connected via this VPN tunnel?

EMG70 · 2023-04-20T21:09:20Z

Above screenshot from 23.04 pre-release we worked on yesterday’s .However ,accessing via home router happens when VPN is enabled across all IIAB installations.

holta · 2023-04-20T21:16:28Z

@EMG70 I suspect VPN is completely unrelated?

e.g. if every device in your home can reach http://box — presumably because your home router is helping to resolve that to either of your Ubuntu Server 23.04 on RPi 400's current 2 IP addresses...

192.168.0.33 == wlan0
192.168.0.38 == eth0

jvonau · 2023-04-20T21:17:35Z

Simple test turn off the vpn and see if you can continue to access the home page. Most likely your router is providing local dns name resolution for your private lan.

EMG70 · 2023-04-20T21:18:57Z

Without VPN I cannot access iiab but only when enabled.

jvonau · 2023-04-20T21:26:43Z

I'm at a loss to explain what you are experiencing, over to Adam.

jvonau · 2023-04-20T21:30:26Z

Followup in the new issue please.

EMG70 · 2023-04-20T21:32:11Z

I'm at a lose to explain what you are experiencing, over to Adam.

I apologise, I have turned VPN enabled-False but can still access iiab via home router.
This could have been happening all along without noticing.

EMG70 · 2023-04-20T21:34:05Z

After disabling VPN

jvonau · 2023-04-20T21:43:31Z

Um tun0 is still present in this picture

EMG70 · 2023-04-20T21:48:17Z

Um tun0 is still present in this picture

EMG70 · 2023-04-20T21:49:07Z

With tun0 completely removed, I can no longer access IIIAB via home router.

EMG70 · 2023-04-20T21:55:01Z

I have just tried as Adam advised to log via IP 192…33 & 192…38 I can confirm I can still access iiab via home router.
Apologies I have to leave for work now.Catch up tomorrow.
