Was für ein Monat! Im Oktober durfte ich Dank Arbeitgeber und Linux Magazin die LinuxCon und CloudOpen 2014 in Düsseldorf besuchen. Während der Messe schrieb ich dementsprechend fleißig für http://www.linux-magazin.de News: Linux Foundation stellt Dronecode vor Die Core Infrastructure Initiative ruft zu mehr Beteiligung auf HA-Richtlinien für Open Stack An dieser Stelle bedanke ich mich […]

Am 06. Oktober 2014 ist ein Artikel von mir zum Thema “Reprepro – Debian-Systeme mit einem selbst aufgesetzten Paket-Repo versorgen” im freiesMagazin 10/2014 erschienen. Der Artikel beschreibt den Aufbau eines Debian-Repositories mit Hilfe des freien Tools reprepro. Am Ende hat der Leser einen Debian-Mirror inklusive eigenem Paket-Pool in der Hand. Vielen Dank an freiesMagazin für […]

Yesterday I struggled with installing new VMs with Debian FAI. As it turned out, both Dracut and the FAI tools failed to mount the NFS exports from the FAI server with NFS, proto=UDP. This happened over night and no apparent reason was found (all NFS deamons, rpc-tools etc. were running on the NFS server), not […]

For this part of my comparison series “Cfengine 3 vs. Puppet” I upgraded my Linux Mint 12 to 13 and switched to Puppet 3.0.2. If you download and try my little code snippets I recommend to use at least Puppet 2.7.14 since this version is able to run the official apt module from Puppetlabs. While […]

Today I had more time to have a closer look at Cfengine 3. Since I am still using Cfengine 2 at work due to a company policy, I would like to gain more knowledge about the latest version of the configuration management tool in my spare time. One day I am hopefully able to port […]

In one of my previous blog posts I wrote about a very simple package management solution with Cfengine 3. Of course installing new packages is only one tiny part of really “managing” packages. But even this little step could fail if the according sources.list file is not correct. So todays’s part of the Cfengine 3 […]

For some strange reason I still have the motivation to look at the “new” Cfengine 3. While I covered editing files and checking for running services in the last posts, I will try to do some very basic package management with Cfengine 3 today. Writing the script body common control { version => "1.0"; inputs […]

Every system admin normally wants to be in full control of his box. One part of the “full control”-thing is to monitor your Linux system. You usually want to know what happens right now and how it affects the system. There are tools like iotop, cbm, htop, top, vmstat and so on, but none of […]

Running a forum for a large community can be exhausting, especially when you need to build everything from the scratch. But before you could start with setting up the sub forums or installing mods, you need to think of the hosting: Where am I going to host the forums? On a shared webhosting package? Or […]

Some of you might have read my little tutorial about how to use Google Skipfish for web vulnerability scanning. While I was fascinated by the efficiency and speed of this application, I started to use it more often. Although manual testing can’t be replaced by a machine, web vulnerability scanners are still a helping hand. During […]
