With grub2 you can directly boot an (iso9660) ISO using its loopback option. This is great because it provides another nice rescue scenario – for example when using grml (the Debian based Linux Live-CD for sysadmins). You no longer need to extract kernel and initrd from the ISO to be able to boot it using […]

Auf der Mailingliste der Linux-User-Group-Graz gab es die Frage, ob man sich darauf verlassen könne, dass die blocks-Einträge in /proc/partitions unter Linux immer eine Größe von 1024 Bytes haben, bzw. wie man das verifizieren kann. Nachdem die Mailingliste aktuell leider kein öffentliches Archiv hat, werfe ich meine Antwort zusätzlich auch hier ein: Ok, zuerst schauen […]

Die letzten Wochen waren dank der Grazer Linuxtage sehr stressig. Direkt danach ging es auch noch auf die Open Source Data Center Conference nach Nürnberg. Ich kann mich Kristian Köhntopp und Michael Renner nur anschließen: super war es! Interessante Leute, Gespräche und Vorträge sowie perfekte Organisation seitens des Veranstalters. Die Folien zu meinem Vortrag ‘grml […]

I hope you know the comics of xkcd and abstrusegoose about Unix time. Unix time? Unix time, or POSIX time, is a system for describing points in time, defined as the number of seconds elapsed since midnight Coordinated Universal Time (UTC) of January 1, 1970, not counting leap seconds. It is widely used not only […]

I got a mail from Linux New Media telling me that they want me as jury member for the Linux New Media Award. The process is simple and for now they just ask me to send my nominations for the following categories: Outstanding Contribution to Open Source / Linux / Free Software Most Linux / […]

Ein Windows-Tool zum Flashen einer Dreambox DM600PVR zu Verwenden ist klarer Stilbruch. Via TFTP wäre es vertretbar aber umständlich. Das geht viel einfacher wenn man die Dreambox übers LAN erreicht: telnet $IP_OF_DREAMBOX mount -o remount,rw /boot rm /boot/* reboot Im Browser dann auf $IP_OF_DREAMBOX gehen und über den Punkt Firmware-Upgrade das gewünschte nfi-Image hochladen und […]

Die Funktionstasten (F1, F2,…) von Apple-Tastaturen erfordern je nach Modell das Drücken der Funktionstaste (fn), um unter Linux wie gewohnt zu funktionieren – wie es der Aufdruck auf der Tastatur auch schon andeutet. Dafür gibt es einen Workaround, Powerbook-Usern wird vielleicht das Stichwort pb_fnmode (/sys/module/hid/parameters/pb_fnmode) was sagen. Das war auf dem USB-Tastatur-Modell MB110D/A und Linux-Kernel […]

The advent calendar started with a Zsh tip, let’s end the advent calendar session with a Zsh tip: globbing. Globbing is like pattern matching. When running ‘ls *.txt’ you’re using globbing. But the globbing feature inside Zsh is much more powerful. Quoting the H-Glob function (“help globbing”) of grml’s Zsh configuration: % H-Glob / directories […]

Nagios is a well known and established Open Source Monitoring System. It’s flexible, easy to deploy and a tool every sysadmin should know how to deal with. I guess most readers of my blog use or at least know Nagios so I’ll keep this blog entry short. But one tip for sysadmins managing Debian systems: […]

The console mail client mutt has some nice features and I noticed that even some long time users of mutt don’t use some of the most rocking features. What’s definitely worth knowing: patterns. Want to display only mails sent from foo@example.org? Select the limit command to show only messages matching a pattern (bound to ‘l’ […]

I wrote about FAI for deploying systems a few days ago – but FAI might be too much overhead if you want to install just some few Debian systems and prefer to use a configuration system like puppet instead. Then using grml-debootstrap might be an option for you. As you might know grml is a […]
