Alright, Debian GNU/Linux 5.0 AKA as Lenny has been released. Time for a Debian unstable unfreeze party! 8-) What does the new stable release bring for system administrators? I’ll give an overview what news you might expect when upgrading from Debian GNU/Linux 4.0, codename Etch (released on 8th April 2007) to the current version Debian […]

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 […]

I blogged about some tips for optimizing the workflow on the command line in my advent calendar already (like irssi backlog completion, Zsh keybindings and hashes in the zsh). When optimizing your workflow you should be aware of what exactly is eating up your time. Start with evaluating your top 10 shell commands, in Zsh […]

One of the reasons why Zsh rocks so much is its completion system. Tab, tab, tab…. Using default Zsh without an useful configuration? Then start with loading the completion system: autoload -U compinit && compinit Now check out the completion system with tools that provide lots of options, like for example gpg and rsync. Then […]

grml-live is a buildsystem for generating a grml and Debian based Linux live system (CD/ISO). It’s based on FAI (I mentioned FAI a few days ago already) because its class concept provides a flexible infrastructure for building custom systems. grml-live uses squashfs-tools for building a compressed file (so you can get >2GB on a 700MB […]

ldapvi is an interactive LDAP client for Unix terminals. Using it, you can update LDAP entries with a text editor. Start exploring it running: ldapvi –discover –host $SERVER If you have to deal with LDAP on the command line and want to use $EDITOR for editing: ldapvi is for you. :)
