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.

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.

Kürzlich wurde auf meinem Pi24-Horchposten die neueste Version von fr24feed installiert: 1.0.26-4, Built on Sep 14 2020 08:32:40 (HEAD-bd20105.git/Linux/static_armel).
Umgehend reagierten meine monit Netzwerksensoren:
Connection failed Service pi24.domain.tld Date: Mon, 14 Sep 2020 19:03:03 Action: alert Host: HOST Description: failed protocol test [HTTP] at [10.1.2.3]:8754 [TCP/IP] -- HTTP error: Regular expression doesn't match: No match Your faithful employee, Monit
Als ich auf das Web-Interface zugreifen wollte erschien auch tatsächlich folgende Fehlermeldung:
For security reasons the web interface is only availble from private class networks or after you have manually specified the bind-interface setting in /etc/fr24feed.ini Please set it to bind-interface="0.0.0.0" to accept traffic from all interfaces or to the IP address of your preferred network interface! For further assistance please contact support@fr24.com
Komisch! Nun gut, ich fügte also bind-interface="0.0.0.0" ans Ende der Datei /etc/fr24feed.ini und bootete den Pi24 neu. Das schaffte keine Abhilfe.
Selbst wenn ich auf dem Pi24 selber ein wget localhost:8754 respektive wget 127.0.0.1:8754 machte, erschien die Fehlermeldung.
Ich tüftelte noch eine Weile lang herum, und entdeckte dabei folgendes: Die neuste Version von fr24feed bindet sich aus irgendeinem Grund nur an IPv6:
$ netstat -tulpn ... Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp6 0 :::8754 :::* LISTEN - ...
Ein Eintrag für denselben Port beginnend mit tcp fehlte.
Das CHANGELOG zeigt auf, dass die Kollegen aktuell an den Netzwerkfunktionalitäten von fr24feed rumbasteln und dabei bereits mehrere Male nachbessern mussten. Offenbar ist auch die neuste Version noch nicht ganz koscher.
Ein Blick in das Log von fr24feed zeigte folgende Einträge:

Komisch! Dem Problem konnte ich nicht auf den Grund gehen, wieso fr24feed die IP des Raspberry Pis nicht herausfinden konnte. strace könnte hier wohl weiterhelfen, doch das ging mir dann doch etwas zu weit. Schlussendlich hatte ich genug und entschied ich mich für ein Downgrade auf eine „last known good“ Version:
$ wget "https://repo.feed.flightradar24.com/rpi_binaries/fr24feed_1.0.25-3_armhf.deb" --no-check-certificate # dpkg -i fr24feed_1.0.25-3_armhf.deb
Damit die neueste Version am nächsten Tag nicht erneut installiert wird, habe ich auch noch /etc/cron.d/fr24feed_updater angepasst:
47 9 1 * * root /usr/lib/fr24/fr24feed_updater.sh >> /var/log/fr24feed_update.log 2>&1
Hoffen wir, dass es bis zum 1. Oktober eine neue Version gibt, die mein Problem behebt.

Mein Dashboard zu Hause läuft auf einem Raspberry Pi 3 mit Debian Buster 10.2. Der RPi lädt beim morgendlichen Neustart um Punkt 05:00 Uhr den Chromium-Browser, welcher die Web-Site mit dem Dashboard aufruft.
Seit ein paar Tagen zeigt Chromium oben rechts ein Layover mit folgender Meldung an:
Can’t update Chromium
Chromium couldn’t update to the latest version, so you’re missing out on new features and security fixes.
(da ich selber kein Photo des Dashboards angefertigt habe, verlinke ich hier auf einen Screenshot eines anderen Benutzers aus dem Internet)
Da Debian kein Update von Chromium anbietet, hilft ein apt-get upgrade chromium hier leider nicht weiter.
Das Symptom behebt man, indem man Chromium mit einem zusätzlichen Kommandozeilenargument startet — nachfolgend ein Auszug aus /home/pi/.config/lxsession/LXDE-pi/autostart:
... @chromium-browser --no-default-browser-check --check-for-update-interval=604800 --disable-pinch --incognito --kiosk
Den Tipp mit --check-for-update-interval=604800 (Eintrag in der Liste der Kommandozeilenargumente) habe ich auf Stack Overflow in der Frage Disable “chrome is out of date” notification gefunden.
Da man als verantwortungsvoller SysAdmin entweder Debian unattended-upgrades respektive cron-apt (Vergleich) eingerichtet hat, oder sich zumindest automatisiert über Paket-Aktualisierungen informieren lässt, ist diese Symptombekämpfung vertretbar.
Die Entwickler von Chromium könnten sich meiner bescheidenen Meinung nach überlegen, ob es nicht besser wäre, nur dann eine Meldung anzuzeigen, wenn auch tatsächlich ein Update verfügbar ist. Denn die Meldung erscheint rein basierend auf dem Alter der Applikation, nicht basierend darauf, ob eine neue Version verfügbar ist:
there’s background process that checks the build date against the current time, and will start to complain if it’s more than 12 weeks ago.

Gestern habe ich einen verstaubten Raspberry Pi 1 aus meinem Endlager für obsolete IT-Hardware gerettet und ihn als arpwatch-Überwachungsstation aufgesetzt. Auf dem Gerät läuft folgendes Debian:
Linux raspberrypi 4.1.13+ #826 PREEMPT Fri Nov 13 20:13:22 GMT 2015 armv6l GNU/Linux
Etwas später stiess ich in Vorbereitung auf meinen Wechsel von upc cablecom zu Fiber7 auf den Artikel Fiber7 performance, in welchem Michael Stapelberg aufzeigt, wie sich die Latenz seiner Internetverbindung nach dem Wechsel von Swisscom auf Fiber7 verbessert hat.
Gedacht — getan: So etwas benötige ich natürlich auch, um meinen bevorstehenden Providerwechsel mit harten Fakten zu untermauern — wobei, ehrlich gesagt, ist mir die Latenz nicht so wichtig (bin kein Gamer), sondern viel mehr der vierfache Durchsatz und die symmetrische Down- und Upload-Geschwindigkeit zum selben Preis wie beim Kabelriesen.
Nichtsdestotrotz installierte ich mir also das Softwarepaket smokeping und seine Dependencies, wie das berühmte rrdtool aus dem Hause Oetiker:
# apt-get update ... # apt-get upgrade ... # apt-get install smokeping
Es wurde zwar alles nett installiert, doch konnte ich danach noch nicht auf die Web-Oberfläche unter http://localhost/smokeping/smokeping.cgi zugreifen. Unter einem x86-64 Debian war das nach der Installation automatisch möglich.
Zuerst wohl mal den Apache starten, dachte ich mir:
# /etc/init.d/apache2 start
Der Web-Server kam hoch, zeigte unter http://localhost/ die obligate Startseite an, doch unter dem Smokeping-Link kam ich statt der Smokeping-Oberfläche nur einen HTTP 403er zu Gesicht (mangels Screenshot und Text-Kopie mittels Auszug aus dem Apache error.log unter /var/log/apache2/):
... [Wed Jan 20 22:52:59.338858 2016] [authz_core:error] [pid 2706:tid 3036673072] [client 10.0.1.101:56967] AH01630: client denied by server configuration: /usr/lib/cgi-bin/smokeping.cgi ...
Oookey … da ich smokeping auch noch auf einem „richtigen“ Linux-Server im Elternhaus laufen hatte, kopierte ich kurzerhand dessen VirtualHost-Konfiguration auf den Raspberry Pi (natürlich als Symlink auf conf-available):
# cat /etc/apache2/conf-enabled/smokeping.conf
ScriptAlias /smokeping/smokeping.cgi /usr/lib/cgi-bin/smokeping.cgi
Alias /smokeping /usr/share/smokeping/www
<Directory "/usr/share/smokeping/www">
Options FollowSymLinks
</Directory>
<Directory "/usr/lib/cgi-bin/">
Options FollowSymLinks
Require all granted
</Directory>
Noch ein …
# apache2ctl graceful
… und der 403er war weg. Das smokeping-GUI wurde aber weiterhin nicht angezeigt, sondern nur der Inhalt des CGI-Scripts im Klartext:
#!/bin/sh exec /usr/share/smokeping/smokeping.cgi /etc/smokeping/config
Was zur Hölle … ? Doch auch diesem Fehlverhalten schaffte ich nach 15 Minuten googlen, Artikel lesen und pröbeln den Garaus: Ein simples
# a2enmod cgi
Via: Perl Apache : Perl script displayed as plain text
reichte aus, und plötzlich führte Apache das CGI-Script aus. Halleluja!

Da ich meinen Raspberry Pi 2 dazu verwende, ein Dashboard anzuzeigen, soll der Taschencomputer nach einem Kaltstart automatisch aufstarten, sich mit dem Standardbenutzer in die graphische Oberfläche einloggen und danach ein Web-Browser-Fenster mit einer bestimmten URL öffnen. Dabei soll nur der Web-Site-Inhalt angezeigt werden, nicht aber die Fensteroberfläche des Window-Managers.
Auf der Kommandozeile öffnet man raspi-config und aktiviert dort die Option Enable Boot to Desktop/Scratch. Wichtig ist, dass man die Option mit den Cursortasten auswählt und danach mittels Tabulator auf „OK“ springt und dieses auch betätigt.
Quelle: RASPI-CONFIG
Damit nun die gewünschte Web-Site angezeigt wird, muss man dem Betriebssystem nun noch sagen, dass bei jedem Login in die grafische Oberfläche ein entsprechender Befehl ausgeführt werden soll:
@xset s off @xset -dpms @xset s noblank @unclutter -idle 1 # PROD #@chromium-browser --incognito --kiosk http://dashboard.local/ # DEBUG @chromium-browser --remote-debugging-port=4444 --show-fps-counter --incognito --kiosk http://dashboard.local/
Quelle: How to auto start chromium after boot on the Raspberry 2 (2015-01-31 debian wheezy)?
Ferner: How To Autostart Apps In Rasbian LXDE Desktop
Auch: Raspberry Pi Dashboard Kiosk
Wichtig: In vielen Anleitungen liest man, dass man die Datei /etc/xdg/lxsession/LXDE-pi/autostart (Raspberry Pi 2) respektive die Datei /etc/xdg/lxsession/LXDE/autostart (Raspberry Pi 1) mit den obigen Befehlen ergänzen soll. In meinem Fall hat das zu einer einstündigen Debugging-Session geführt, die erst mit folgendem Hinweis gelöst werden konnte:
Note: If both files are present, lxsession only executes the local file as of v0.4.9
Aus irgendeinem Grund war bei meiner Installation die Datei ~/.config/lxsession/LXDE-pi/autostart vorhanden, weshalb die Einträge in den generischen autostart-Dateien nie berücksichtigt wurden.
Quelle: LXDE
Damit der Mauszeiger ausgeblendet wird, muss noch folgendes Paket installiert werden:
# apt-get install unclutter
Das Programm wird anschliessend beim Ausführen der Autostart-Datei ausgeführt.
Quelle: Step 16: Hiding the mouse pointer
Dank an Simon Jenny für den Hinweis — leider bleibt der Bildschirm schwarz, diese Lösung funktioniert also derzeit nicht.
xset -dpms & xset s off & unclutter -idle 1 & exec chromium-browser \ --window-position=0,0 \ --window-size=1080,1920 \ --incognito \ --kiosk \ http://dashboard.local/
Folgende zusätzliche Parameter könnten ebenfalls hinzugefügt werden:
... --no-first-run \ --disable \ --disable-translate \ --disable-infobars \ --disable-suggestions-service \ --disable-save-password-bubble \ --disk-cache-dir=/tmp/chromium/cache/ \ --user-data-dir=/tmp/chromium/user_data/ \ --show-fps-counter \ --remote-debugging-port=4444 \ ...
... /usr/bin/xinit /home/pi/.xinitrc & exit 0

Nachdem der Raspberry Pi 2 auf Raspbian Jessy läuft, können wir die neueste verfügbare Version des Chromium-Browsers herunterladen und installieren. Wir bedienen uns dazu der Repositories von Ubuntu und laden uns (Stand 22. Juni 2015) folgende zwei .deb-Pakete herunter:
Die Links zu den vorkompilierten Binaries finden sich auf den beiden Paket-Seiten rechts im Abschnitt „Downloadable Files“.
WICHTIG: Unter Raspberry Pi 1 läuft nur die unter Wheezy verfügbare Version 22 von Chromium. Neuere Versionen funktionieren unter diesem System nicht, weil die ARMv6-CPU des Raspberry Pi 1 keine hardwarebasierte Fliesskommaeinheit mitbringt. Das armhf-Paket von Ubuntu setzt diese CPU-Einheit aber leider voraus. Wer Chromium trotzdem auf dem nachfolgenden Weg installiert, erhält spätestens beim Start von Chromium folgende Fehlermeldung:
$ chromium-browser --version Illegal instruction
Raspberry Pi 2 basiert glücklicherweise auf der ARMv7-Plattform und hat diese Einheit mit an Bord.
Sobald die Dateien im lokalen Dateisystem vorliegen, installiert man sie folgendermassen:
# dpkg -i chromium-browser_43.0.2357.81-0ubuntu0.15.04.1.1170_armhf.deb chromium-codecs-ffmpeg-extra_43.0.2357.81-0ubuntu0.15.04.1.1170_armhf.deb
Quelle: Installing Google Chromium on ARM devices with Flash plugin – solution
Ob die Installation erfolgreich war, zeigt folgender Befehl auf der Kommandozeile:
$ chromium-browser --version Chromium 43.0.2357.81 Built on Ubuntu 15.04, running on Raspbian 8.0

Mittels folgendem Befehl sollte man die Uhrzeit richtig stellen:
# dpkg-reconfigure tzdata
Ausserdem empfiehlt es sich, die Uhrzeit stündlich neu zu stellen:
# apt-get install ntpdate
... * * * * * root ntpdate -s ch.pool.ntp.org ...

Nachdem man SSH-Verbindungen herstellen kann, aktualisiert man zuerst einmal das System. Hierzu loggt man sich per SSH mit dem Benutzer pi ein und wechselt danach zum root-Benutzer:
$ sudo su -
Als nächstes aktualisiert man wie von Debian gewohnt die
# apt-get update
und installiert alle neuen Pakete:
# apt-get upgrade
Ist Wheezy auf dem neuesten Stand, wechseln wir das Repository in folgender Datei zu Jessie:
deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi
Nun führen wir erneut ein
# apt-get update
durch, um die Jessy-Paketliste herunterzuladen.
Jetzt startet die grosse Upgrade-Aktion:
# apt-get dist-upgrade
Nach einigen Stunden und allfälligen Dialogen sollte nach einem Reboot Raspbian Jessy auf dem System laufen.
