Die älteste mir zugängliche Mail von Sven Guckes direkt an mich stammt aus dem Jahr 2002, und startet seinerseits mit: eine dokumentierte loesung – das ist prima! :-) Natürlich ging es um: Vim. Viele Mails unter anderem zum Kunsthaus Graz, den Chemnitzer Linux-Tagen, den Grazer Linuxtagen (GLT) und seinem Geek Brunch sollten folgen. Unvergessen bleibt […]
Continuing with #newinbullseye. One package that isn’t new but its tools are used by many of us is util-linux, providing many essential system utilities. There is util-linux v2.33.1 in Debian/buster and util-linux v2.36.1 in Debian/bullseye, and as usual there are many new features and options available. I don’t want to replicate the release notes provided […]
Continuing with #newinbullseye, it’s worth being aware of, that efivars is gone with the kernel version shipped as of Debian/bullseye. Quoting from wiki.debian.org/UEFI: The Linux kernel gives access to the UEFI configuration variables via a set of files under /sys, using two different interfaces. The older interface was showing files under /sys/firmware/efi/vars, and this is […]
Debian v11 with codename bullseye is supposed to be released as new stable release soon-ish (let’s hope for June, 2021! :)). Similar to what we had with #newinbuster and previous releases, now it’s time for #newinbullseye! I was the driving force at several of my customers to be well prepared for bullseye before its freeze, […]
It all started with the big bang! We nearly lost 33 of 36 disks on a Proxmox/Ceph Cluster; this is the story of how we recovered them. At the end of 2020, we eventually had a long outstanding maintenance window for taking care of system upgrades at a customer. During this maintenance window, which involved […]
(Blogging this, since this is a recurring anti-pattern I noticed at several customers and often comes up during deployments of 3rd party repositories.) Update on 2021-02-19: clarified, that Signed-By requires apt >= 1.1, thanks Vincent Bernat Many upstream projects provide Debian repository instructions like this: curl -fsSL https://example.com/stable/debian.gpg | sudo apt-key add – Do not […]
We did it again™, at the end of June we released Grml 2020.06, codename Ausgehfuahangl. This Grml release (a Linux live system for system administrators) is based on Debian/testing (AKA bullseye) and provides current software packages as of June, incorporates up to date hardware support and fixes known issues from previous Grml releases. I am […]
Disclaimer: I started writing this blog post in May 2018, when Debian/stretch was the current stable release of Debian, but published this article in August 2019, so please keep the version information (Debian releases + kernels not being up2date) in mind. The kernel version of Debian/stretch (4.9.0) didn’t support the RAID controller as present in […]
Es ist schon ein Weilchen her, aber nachdem mich noch immer Leute darauf ansprechen: Auf den Grazer Linuxtagen 2019 (GLT19) war ich als Referent mit einem Vortrag zum Thema “Best Practices in der IT-Administration, Version 2019” vertreten. In dem 25-minütigen Vortrag geht es um die moderne IT-Administration und welche Best Practices es im Jahr 2019 […]
Debian buster is there, and similar to what we had with #newinwheezy, #newinjessie and #newinstretch it’s time for #newinbuster! One package that isn’t new but its tools are used by many of us is coreutils, providing many essential system utilities. We have coreutils v8.26-3 in Debian/stretch and coreutils v8.30-3 in Debian/buster. Compared to the changes […]
Debian buster is there, and similar to what we had with #newinwheezy, #newinjessie and #newinstretch it’s time for #newinbuster! Update on 2019-07-26 22:55 UTC: Cyril Brulebois pointed out, that findmnt (find a filesystem) was available in Debian/stretch already as part of the mount package, updated the blog post accordingly One package that isn’t new but […]
Back in 2006 I started to write a tool called grml-debootstrap. grml-debootstrap is a wrapper around debootstrap for installing Debian systems. Using grml-debootstrap, it’s possible to install Debian systems from the command line, without having to boot a Debian installer ISO. This is very handy when you’re running a live system (like Grml or Tails) […]
Auf den Grazer Linuxtagen 2018 (GLT18) war ich als Referent mit einem Vortrag zum Thema “Best Practices in der IT-Administration, Version 2018” vertreten. In dem 25-minütigen Vortrag geht es um die moderne IT-Administration und welche Best Practices es im Jahr 2018 gibt. Es gibt den Vortrag als Videomitschnitt auf YouTube sowie in verschiedenen Formaten auch […]
Am Dienstag (20.03.2018) findet das nächste Treffen der Infracoders-Graz statt. Ich wurde eingeladen einen Vortrag zu halten und werde zum Thema “Best Practices in der IT-Administration” referieren. Was: Vortrag zu “Best Practices in der IT-Administration” Wann: Dienstag, 20.03.2018 um 19:00 Uhr Wo: Aula X Space, Georgigasse 85, Graz Eintritt frei
It all started with a tweet of mine: I received quite some feedback since then and I’d like to iterate on this. I’m a puppet user since ~2008 and since ~2015 also ansible is part of my sysadmin toolbox. Recently certain ansible setups I’m involved in grew faster than I’d like to see, both in […]
The Debian stretch release is going to happen soon (on 2017-06-17) and since our latest Grml release is based on a very recent version of Debian stretch I’m taking this as opportunity to announce it also here. So by the end of May we released a new stable release of Grml (the Debian based live […]
Debug packages include debug symbols and so far were usually named <package>-dbg in Debian. Those packages are essential if you’ve to debug failing (especially: crashing) programs. Since December 2015 Debian has automatic dbgsym packages, being built by default. Those packages are available as <package>-dbgsym, so starting with Debian/stretch you should no longer look for -dbg […]
Repeating what I did for the last Debian releases with the #newinwheezy and #newinjessie games it’s time for the #newinstretch game: Debian/stretch AKA Debian 9.0 will include a bunch of packages for people interested in digital forensics. The packages maintained within the Debian Forensics team which are new in the Debian/stretch release as compared to […]
We’re coming closer to the Debian/stretch stable release and similar to what we had with #newinwheezy and #newinjessie it’s time for #newinstretch! Hideki Yamane already started the game by blogging about GitHub’s Icon font, fonts-octicons and Arturo Borrero Gonzalez wrote a nice article about nftables in Debian/stretch. One package that isn’t new but its tools […]
Recently we had a WTF moment at a customer of mine which is worth sharing. In an automated deployment procedure we’re installing Debian systems and setting up MySQL HA/Scalability. Installation of the first node works fine, but during installation of the second node something weird is going on. Even though the deployment procedure reported that […]
