WatchDog for Raspberry Pi

Leave a comment
Debian / Raspberry Pi

for a Raspberry Pi used in remote, automated systems watchdog timers are essential. “A watchdog timer (sometimes called a computer operating properly or COP timer, or simply a watchdog) is an electronic timer that is used to detect and recover from computer malfunctions. During normal operation, the computer regularly resets the watchdog timer to prevent it from elapsing, or “timing out”. If, due to a hardware fault or program error, the computer fails to reset […]

Debian

in den letzten tagen hab ich ein paar alte laptops und schwachbrüstige nettops mit Debian Jessie und einem hüpschen XFCE bestückt. hüpsch hier meint mit Greybird Theme und Faenza Icons. nachdem ich wahrscheinlich in die verlegenheit komme das noch öfters zu tun oder wahrscheinlich sogar danach gefragt werde, wie ich denn das bewerkstelligt habe, darf ich das in diesem blog-eintrag für die nachwelt festhalten.

was mich schon seit längerem stört, daß mein USB-kartenleser keine karten mehr erkennt (eigentlich alle auf allen rechnern), außer, man steckt ihn mit geladener karte frisch an oder die karte steckt schon während des bootens drinnen. dieses problem ist auch ausführlich hier beschreiben. ich selbst kann mich nicht mehr erinnern, seit wann dieses fehlerbild aufgetreten ist. die lösung dazu ist jedenfalls ganz einfach: kernel polling aufdrehen. bleibt der nachwelt herauszufinden, warum denn das plötzlich nicht mehr so ohne […]

Apache / Debian / PHP

won’t talk about pros and cons of PHP-FPM, FastCGI, APC and all that stuff, there are tons of articels around, see also the links below. main urge was to speed up PHP with APC, get rid of preforked Apaches, run PHP scripts as their native user and many more. just giving an overview how I’ve easily set it up here, having different “customers” programming their own PHP scripts and also Debian packages ready to run.

as Andrea described there is an easy way to force iptables to log into its own logfile. I’d like to sum it up in this post. you need to change all your log-prefixes to have a unique keyword, e.g. netfilter as I do in the following example. afterwards just add some filter conditions for rsyslogd. place a file called 10-iptables.conf into /etc/rsyslog.d/ with the following content. both lines match on every log message containing netfilter, […]

build your own basic Raspberry Pi Debian image

Debian / Raspberry Pi

Outdated! May I point you to Raspbian Lite Image by the Raspberry Pi Foundation. Outdated! May I point you to raspbian-ua-netinst. Seems that I’m one of these lucky guys already received their Raspberry Pi. I ordered it from RS on the 5th and got it on the 10th of May. Posted my unboxing on Google+. But which distribution should I install? There are many on the downloads page. First choice was the Debian image, because I’m […]
