eduroam works quite well on openbsd, provided that ones network card is supported. The “standard tutorial” seems to be this one. However for me the problem is, that it requires us to store the eduroam password, which often is also the single-sign-on (e-mail, services, etc.) for a university, in plain text. To avoid this, I …
The Google App Engine offers a maven project that uses jetty to launch a local test server. This is convenient and works quite well, but jetty suffers from one problem when running in a virtual machine: It needs a full entropy pool to start-up (probably to generate encryption keys?). The problem is that virtual machines …
I have to compile gstreamer on different computers and thus wrote this little script to fetch the sources and compile them. Note that you need to install dependencies first. gstreamer will usually compile when they are not present, but will then not work properly. You can download it here: gstreamer_build.sh #!/bin/bash # you might …
Here is a useful little command to get a quick overview over nearby hotspots: iw dev wlan0 scan | grep ‘SSID\|signal\|primary channel’ SSID: 5g_station * primary channel: 36 signal: -42.00 dBm SSID: 2g_station * primary channel: 6 signal: -72.00 dBm iw dev wlan0 scan | grep ‘SSID\|signal\|primary channel’ SSID: 5g_station * primary channel: 36 signal: …

I started to roll out puppet to manage our servers at work and have to say I am impressed. It really changed the way I think about managing systems and is so much cleaner and easier to understand than the ‘traditional’ way. Just being able to automate often repeated steps like enabling LDAP access or …
Running it for the first time, it seams to work well. It upgraded the packages and send me an e-mail. Here are the config files I used: /etc/apt/apt.conf.d/02periodic: 1 2 3 4 5 6 APT::Periodic::Enable "1"; APT::Periodic::Update-Package-Lists "1"; APT::Periodic::Download-Upgradeable-Packages "1"; APT::Periodic::AutocleanInterval "5"; APT::Periodic::Unattended-Upgrade "1"; APT::Periodic::RandomSleep "3600";APT::Periodic::Enable "1"; APT::Periodic::Update-Package-Lists "1"; APT::Periodic::Download-Upgradeable-Packages "1"; APT::Periodic::AutocleanInterval "5"; APT::Periodic::Unattended-Upgrade "1"; …
This is a simple test post to check if I can directly post from my blog to facebook…
I finally got around to connect my blog to my facebook account and run into trouble enabling a developer account. To use the wordpress facebook plugin you need to create a facebook app that can post to your facebook account. To create the app you need a facebook developer account. So far so simple. The …
To automate the installations of updates on our servers I am experimenting with the package unattended-updates. Good introductions can be found here: http://syslog.tv/2012/01/28/automaticunattended-updates-on-debian-6-squeeze/ http://mb.walter.silvergeeks.com/rechner/automatische-updates-aus-security-in-debian-stable/ https://help.ubuntu.com/community/AutomaticSecurityUpdates/#Using_the_.22unattended-upgrades.22_package I have to admit that I am a bit uneasy, but in the past year of applying updates by hand nothing ever broke. So I assume that this should not …
