Elgato Key Light Air wird von Control App unter iOS und macOS nicht mehr erkannt

Link zu diesem Artikel

Gestern fand die Elgato Control App unter iOS mein Elgato Key Light Air plötzlich nicht mehr im Netzwerk. Auch die nachträglich installierte Control App unter macOS Big Sur meldete kein Licht zur Steuerung.

Ich setzte das Licht mehrere Male zurück, und verband es mit Müh und Not wieder mit dem WLAN. Das alles half nichts.

Mysteriös: Mein DHCP-Server erteilte dem Licht eine statische IP, und ich konnte die Lampe von allen Geräten aus auch pingen. Doch die Control App sah die Lampe nicht; ich vermute, dass es ein Problem mit Apples Bonjour gab.

Einige Ansätze: UniFi AP-AC-PRO Not Crossing mDNS/Multicast/Broadcast between 2.4GHz and 5GHz Networks?, iTunes Remote Multicast / Bonjour 2.4/5GHz Radio Issue).

Das Schlimmste am Ganzen: Das Licht verfügt einzig über einen Ein- und Ausschalter. Das Licht selber kann man aber nur über die App steuern (Helligkeit, und Lichttemperatur).

Auch der Trick mit der manuellen Anpassung von Settings.xml (auch: Elgato Control Center Settings.xml) funktionierte nicht, weil sich unter macOS keine solche Datei findet. Immerhin fand ich das Einstellungsverzeichnis (~/Application Support/com.corsair.ControlCenter), und (jetzt erst beim Schreiben des Blog-Artikels) die Einstellungsdatei (~/Preferences/com.corsair.ControlCenter.plist)

Was genau das Problem verursacht hat, kann ich nicht mit Sicherheit sagen. Aber allenfalls hat ein mehrmaliger Reboot meiner UniFi-Access Points während der Debugging-Übung das Problem unbeabsichtigt gelöst.

Doch zu dem Zeitpunkt hatte ich mir auf Basis von Automating Elgato Key Lights From macOS Touch Bar bereits selbst geholfen. Folgende zwei Scripts lassen einen die Lampe einschalten und eigene Lichtwerte einstellen, sowie die Lampe ausschalten:

on.sh

#!/bin/bash

IP="1.2.3.4"

BRIGHTNESS="100" #max
TEMPERATURE="256" #max

if [ $# -gt 0 ]
then
    BRIGHTNESS="$1"
fi

if [ $# -gt 1 ]
then
    TEMPERATURE="$2"
fi

DATARAW="{\"lights\":[{\"brightness\":$BRIGHTNESS,\"temperature\":$TEMPERATURE,\"on\":1}],\"numberOfLights\":1}"

curl --location --request PUT "http://$IP:9123/elgato/lights" \
--header 'Content-Type: application/json' \
--data-raw "$DATARAW"
echo ""

exit 0

off.sh

#!/bin/bash

IP="1.2.3.4"

curl --location --request PUT "http://$IP:9123/elgato/lights" \
--header 'Content-Type: application/json' \
--data-raw '{"lights":[{"on":0}],"numberOfLights":1}'
echo ""

exit 0

Als nächstes würde es mich reizen, für den Geschäftslaptop diese Funktionalität auch gleich noch auf die Touchbar zu legen, wie im Artikel weiter unten beschrieben

Mittlerweile „sendet“ die Lampe (wieder) unter Bonjour. Discovery.app zeigt folgenden Eintrag an:

_elg._tcp. - 1 item
Elgato
elgato.local.
1.2.3.4:9123
[fe80::]:9123
mf=Elgato
dt=200
id=3C:6A:9D:00:00:00
md=Elgato Key Light Air 123456789
pv=1.0

Unter Linux mit installierten avahi-utils kann man vermutlich mit folgendem Befehl dieselbe Information extrahieren:

$ avahi-browse -a

Raspberry Pi meldet „Workqueue: events_freezable mmc_rescan“ (Virtual Memory/Swap-Problem)

Link zu diesem Artikel

Nachtrag: Leider hat diese Einstellungsänderung keine nachhaltige Abhilfe gebracht. Nach einem Umzug trat das Problem übrigens nicht mehr morgens um 4 Uhr auf, sondern abends nach 19 Uhr. Was ich jetzt stattdessen mache: Den RPi zwei Mal am Tag neu booten (um 5 Uhr, sowie um 17 Uhr). Das hat effektiv geholfen, das Problem tritt nicht mehr auf.

Seit einiger Zeit ging mein Raspberry Pi 3 zwischen 4 und 5 Uhr morgens „offline“. Meine monit-Installationen meldeten mir dann jeweils, dass der SSH-Server auf dem RPi nicht mehr zu erreichen war (gestern bspw. traf die Meldung um 4:24 Uhr ein).

/var/log/syslog enthielt nachfolgende Meldungen. Die Nennung von mmc_get_card liess mich aufhorchen, weshalb ich eine neue Micro SD-Karte bestellte und die alte Karte auf die neue klonte. Leider liess sich damit das Problem nicht beheben.

Die Lösung fand ich via Pi freezing up 4 times a day – Workqueue: events_freezable mmc_rescan #1522 und via SWAP on Raspberry Pi / SD = AUTOCRASH und via Workqueue: events_freezable mmc_rescan crash with Raspbian kernel 4.14.79-v7+ hier: Linux Kernel panic issue: How to fix hung_task_timeout_secs and blocked for more than 120 seconds problem:

In /etc/sysctl.conf fügte ich folgende Zeilen ein:

...
vm.dirty_background_ratio = 5
vm.dirty_ratio = 10
...

Bis dahin waren folgende Werte aktiv:

# sysctl -a | grep -i dirty
vm.dirty_background_bytes = 0
vm.dirty_background_ratio = 10
vm.dirty_bytes = 0
vm.dirty_expire_centisecs = 3000
vm.dirty_ratio = 20
vm.dirty_writeback_centisecs = 500
vm.dirtytime_expire_seconds = 43200

Danach ein Reboot. Heute trat das Problem nicht auf, aber ich beobachte die Situation weiter.

/dev/disk unter macOS deutlich langsamer als /dev/rdisk

Link zu diesem Artikel

Kürzlich beim zurückschreiben eines SD-Card RPi Backups auf eine neue SD-Card:

Starting imaging './emeidi-dashboard.img' to /dev/disk4 ...
^C11128+0 records in
11127+0 records out
11667505152 bytes transferred in 3849.682711 secs (3030771 bytes/sec)
Done.

3030771 bytes/sec, das sind 2959 kilobytes/sec oder 2.89 megabytes/sec. Eine 32GB SD-Card schreibt man also in 11’072 Sekunden, das heisst … in unglaublich langen 3 Stunden.

Synology NAS fsck-en

Link zu diesem Artikel

Zum zweiten Mal innert neuen Monaten hat mein Synology NAS folgendes Problem:

(rsync, nächtlich auf meinem iMac laufend, welches iPhotos auf das NAS sichert)

...
rsync: recv_generator: failed to stat "/var/services/homes/mario/Backup/imac-photos/resources/proxies/derivatives/3d/01/13dc2/UNADJUSTEDNONRAW_thumb_13dc2.jpg": Input/output error (5)
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1307) [sender=3.2.2]

Die Lösung: Dateisystem flicken! Das geht folgendermassen:

  1. Mit SSH auf das NAS einloggen
  2. sudo su -
  3. syno_poweroff_task -d
  4. Wenn dieses Kommando erfolgreich durchläuft, wird die SSH-Verbindung gekappt
  5. Mit SSH erneut auf das NAS einloggen
  6. sudo su -
  7. vgchange -ay
  8. e2fsck -v -f -y /dev/vg1000/lv

Die Dateisystemreparatur startet nun (destruktiv!). Wer zuerst gefahrlos wissen möchte, was wirklich los ist, kann anstelle des letzten Befehls auch folgenden Befehl verwenden: e2fsck -v -n -f /dev/vg1000/lv

Im Dezember 2020 funktionierte das auf einen Rutsch, im August 2021 musste ich das NAS einmal neu starten, weil sonst folgende Fehlermeldung angezeigt wurde:

# e2fsck -v -f -y /dev/vg1000/lv
/dev/vg1000/lv is in use.
e2fsck: Cannot continue, aborting.

Die Informationen hier wurden aus folgenden Quellen zusammengeschustert (chronologisch, die besseren Quellen befinden sich somit am Ende der Liste):

Apple CarPlay funktioniert in einem VW Sharan nicht mehr

Link zu diesem Artikel

Diese Woche waren wir mit der Familie meiner Frau in einem Mietwagen — einem Volkswagen Sharan mit allen Schikanen — in der Schweiz unterwegs.

Am Donnerstag-Morgen kurz nach der Abfahrt dann folgendes Problem:

Egal mit welchem USB-zu-Lightning-Kabel und welchem iPhone (das 11 Pro meiner Frau, sowie mein XS): Wir konnten kein Apple CarPlay auf den Bildschirm zaubern.

Connection failed.

Please make sure your mobile device is unlocked.

Nach etwas Recherche im Internet dann die Lösung:

What I do is hold down the power button on the radio console for 10-15 seconds, this is comparable to a hard reset of the system.

Works every time.

Quelle: CarPlay stopped working today

Nach etwa 5 Sekunden Druck auf den Power-Knopf (⏻) erfolge der Neustart des Entertainment-Systems, und wenig später konnte Apple CarPlay wieder geladen werden.

OpenVPN warnt MULTI: packet dropped due to output saturation (multi_process_incoming_tun)

Link zu diesem Artikel

Fri Jun 25 21:10:49 2021 us=113808 user1/1.2.3.4:7609 MULTI: packet dropped due to output saturation (multi_process_incoming_tun)

Es gibt offenbar zwei Lösungen für das Problem:

  • UDP: Das VPN anstelle über TCP mittels UDP aufbauen (aufwändig; erfordert den Rollout einer neuen Konfigurationsdatei auf alle Clients).
  • TCP Queue Limit erhöhen: Serverseitig fügt man in die Serverkonfiguration die Zeile tcp-queue-limit 256 ein und startet den Server neu (Quelle)

Letzteres scheint bis jetzt gut zu klappen.

Mit der upc App über Mobilfunk-Roaming aus dem Ausland fernsehen

Link zu diesem Artikel

Ein Kollege hat mich kürzlich gefragt, wieso er trotz des von mir geliehenen VPN-Zugangs im Ausland mit der upc App keine aufgezeichnete Sendung schauen kann.

Er war im 4G-Netz des Landes eingebucht und hatte VPN aktiviert. Doch die upc App sagte ihm:

Nicht verfügbar

Dieses Video ist ausserhalb deiner Region nicht verfügbar

Komisch. Wie zum Teufel wusste die App, dass der Kollege im Ausland war — auf IP-Ebene kommunizierte der Kollege nämlich mit einer 100-prozentig Schweizerischen IP? Daran konnte es nicht liegen.

Mir schwante Böses, und bat ihm, unter Settings > Privacy > Location Services der upc App die Rechte zu entfernen, den Standort zu eruieren. Gesagt, getan, worauf die App folgendes anzeigte:

Ich war schon mit meinem Latein am Ende, als ich den Text noch einmal genau las: „Um ein Video über die mobile Netzwerkverbindung abzuspielen, …“.

Ich bat den Kollegen, auf einem zweiten Telefon den Hotspot zu aktivieren, sein Telefon damit zu verbinden, und dann VPN zu starten.

Dann klappte es und er konnte die aufgezeichnete Sendung streamen. Aus Sicht seines Telefones war er nämlich nun mit einem WLAN verbunden. Und upc scheint bei dieser Verbindungsart den Standort des Telefons nicht abzufragen.

EdgeRouter ER-X wird mit aktiviertem hwnat bei Facetime-Anrufen instabil

Link zu diesem Artikel

Seit einiger Zeit fällt mir auf, dass FaceTime Video-Anrufe von mir (Fiber7, 1 Gbit/s symmetrisch) zu einem Bekannten (upc, mit ein paar 100 MBit/s up- and down, best effort) ruckeln und stocken.

Die Probleme beginnen wenige Sekunden nach der Etablierung des Anrufs. Symptome:

  • Pings von mir aus an die öffentliche IP-Adresse des Bekannten liegen normalerweise im 20-30ms Bereich. Während Facetime-Anrufen ist das in ca. 60-70 Prozent der Fälle weiter so, dann aber kommt es vor, dass die Latenz mehrerer aufeinanderfolgenden Pakete auf bis zu 600ms hochschnellt. Es kommt auch immer wieder vor, dass Ping-Pakete komplett verloren gehen.
  • Smokeping auf die öffentliche IP-Adresse des Bekannten zeigt einen besorgniserregenden Packet Loss.
  • Der Endpunkt eines OpenVPN-Tunnels beim Bekannten vermeldet zur selben Zeit wiederholt folgende Warnungen: 
    Thu May 27 21:44:10 2021 Authenticate/Decrypt packet error: bad packet ID (may be a replay): [ #33668492 / time = (1621559394) Fri May 21 03:09:54 2021 ] -- see the man page entry for --no-replay and --replay-window for more info or silence this warning with --mute-replay-warnings

Screenshots:

Die (triviale) Lösung: Auf dem EdgeRouter ER-X mit Firmware v1.10.0 muss das sog. Hardware Offloading (kurz hwnat) deaktiviert werden:

Offizielle Anleitung (CLI), aber dasselbe geht auch über das GUI und den Config Tree: System > Offloading > hwnat = disable.

Das Problem ist im Support-Eintrag Connecting to wireguard on edgerouter messes up outgoing UDP packets #23 beschrieben, mitsamt der Lösung:

If you use a Mediatek device with hwnat your UDP packages might get lost. Currently the only solution is to disable hwnat

UDP re-order problem

With hwnat disabled, the wg0 interface works great and the ER-X routes all my internet traffic out of it just fine, although CPU has much more overhead.

As soon as I enable hwnat, I start seeing problems, but only in certain scenarios, not all. For example, with hwnat disabled, I can use OpenVPN as a client on a local machine. Thus that OpenVPN connection gets routed out through the wg interface first, then on to server. The OpenVPN server shows the endpoint IP of the server ER-X wg is connected to as the OpenVPN client’s IP, not my ISP IP (what I want). As soon as I enable hwnat, this breaks. I can still make the initial outgoing connection and bring up the OpenVPN tunnel, but packets get dropped so that OpenVPN through the wg interface is unusable with hwnat enabled.

Also noticed Apple FaceTime is broken when hwnat is enabled with wg interface. Lots of disconnects and moments of me hearing them but them not hearing me. Again, disabling hwnat fixes it instantly, but again, at the cost of CPU.

Nachtrag

Das Problem ist leider immer noch nicht gelöst. Zuerst einmal scheint die Deaktivierung von hwnat über das Web GUI erst dann zu greifen, wenn man den Router neu startet. Bei mir zeigte das GUI „disabled“ an, doch auf der Kommandozeile erschien folgendes:

$ configure
[edit]
user@ROUTER# show system offload hwnat
 hwnat disable

$ show ubnt offload
IPSec offload module: loaded

HWNAT offload module: loaded

Traffic Analysis    :
  export    : disabled
  dpi       : disabled
    version       : 1.354

Nach dem Neustart dann:

$ show ubnt offload
IPSec offload module: not loaded

HWNAT offload module: not loaded

Traffic Analysis    :
  export    : disabled
  dpi       : disabled
    version       : 1.354

Trotz alledem macht FaceTime weiterhin Probleme.

setlocale: LC_ALL: cannot change locale

Link zu diesem Artikel

Seit ich mein MacBook Air mit M1-Chip und macOS Big Sur verwende, erhalte ich beim Login auf meinen Raspberry Pi 3 über SSH folgende Warnung zu Gesicht:

ssh dashboard
Linux DASHBOARD 5.10.17-v7+ #1403 SMP Mon Feb 22 11:29:51 GMT 2021 armv7l
Last login: Sat May  8 05:00:24 2021
-bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

Ursache des Problems: en_US.UTF-8 ist in /etc/locale.gen kommentiert:

$ cat /etc/locale.gen | grep -v "^#"

en_GB.UTF-8 UTF-8

Somit die Datei öffnen, die Zeile mit en_US.UTF-8 suchen, ent-kommentieren, speichern und dann folgenden Befehl ausführen:

# locale-gen

Via: warning: setlocale: LC_ALL: cannot change locale

Beim nächsten Login erscheint die Fehlermeldung nicht mehr.
