After the official party called “wired dreams” @StuZ on Friday, I was a bit late and arrived @ETH in the early afternoon. At 14:00 there was the (from my point of view) probably best workshop, it was about Puppet. Puppet is an open source data center automation and configuration management tool. For more information see http://www.puppetlabs.com/. There is also a Swiss Puppet User Group. It seems to mostly active in western Switzerland. The second interesting talk was about collectd, a ….Read More

RHN Satellite 5.4 release in sight
When analyzing recent Bugzilla-reports and mailing list posts, we can expect a RHN Satellite release quite soon. Why? The main reason for this is the lack of SHA256 support in sat530. Since RHEL6 packages having SHA256 checksums, the release of Satellite 5.4 is a prerequisite for releasing RHEL6. As always there will also be a large load of bugfixes included. Expected new features yum repository syncronising Support for SHA256 checksums Maybe support for SHA384 checksums Support for Oracle 11g databases ….Read More

Triggers are a very welcome and powerful method to automate things before, during after installation of a system. At the moment it only works with python scripts. Since not every sysadmin knows python, but everyone knows to write bash scripts, this is a major drawback. Cobbler is included in ….Read More
Ubuntu 10.04 LTS released
End of April 2010, Ubuntu 10.04 was released. As always it is based on Debian’s Testing-Release. Canonical “stabilizes” the testing tree of Debian and adds its own look. This time, Ubuntu radically changed its look. From my point of view it looks ugly, very ugly. Strange colors, low contrasts in menus, orange icons in Nautilus… window buttons on the left side… At the end of the day an usability-horror. Under the hood Ubuntu is a very stable distribution with recent ….Read More

Managing CentOS with Spacewalk
Red Hat RHN Satellite In 2003 Red Hat released its RHN Satellite server as a closed source management tool for RHEL and only for RHEL (okay, a legacy support for managing Solaris is available).

Additionally to the RHN satellite subscription fee you need at least a subscription for the ….Read More
