Today, Red Hat released its “service pack” or “maintenance release” of RHEL4. According to Red Hats life cycle policy” it ends the production stage two. That means: In future only bugs with a high severity will be fixed. The “normal” life cycle of RHEL4 will end in approx. one year. This means that everyone using RHEL4 systems should think about a migration scenario to RHEL6. Unfortunately, Red Hat does not support OS upgrades, you need to install the systems from ….Read More

CentOS6 to be released in the next few weeks
According to an interview with Karanbir Singh – a major contributor to the project – it is just a question of a few weeks until we can expect CentOS6 to be released. CentOS is extremely important for the RHEL community, it is a playground for trying out new stuff before getting into an engineering phase with the Red Hat supported RHEL. Lets have fun with it…
Epson scanners on Linux systems
I’ve got a Epson Perfection 1260 Photo scanner. Fedora like other distributions such as OpenSuse are recognizing the device since a long long time. The back end chosen for the device is plustek. Unfortunately when using the default configuration one experience very strange effects with colours. The left and the right 50% of the picture have a colored background, even when scanning a empty page. I had this problem with OpenSUSE since years and still got it with Fedora 1x. ….Read More
Spice and RHEV, a RHCE goes MCSE
I’m currently working in a project which includes some virtual Linux desktops. The desktop of choice is RHEL6. How to bring a Linux desktop via WAN to a thin client? VNC -> are you nuts? Remote X11 over SSH -> WAN = no go. NX -> another vendor involved. SPICE -> Spicy! But: Spice over WAN? To be tested… SPICE is the protocol used by RHEV (Red Hat Enterprise Virtualization). Some time ago I had the chance to test this ….Read More
Some impressive figures about Spacewalk and my two cents
Today, I saw a interessing post on the spacewalk-devel mailing list. Lines of code Spacewalk has 2,908,841 lines of code, created in estimated 843 person years. This means 843 developers are needed to rewrite Spacewalk from scratch in one year! That’s amazing. Number of bugs fixed As stated in the post, the Spacewalk-team fixed 1012 bugs in the year 2010. Some 1061 bugs are still due to be solved, the Spacewalk-team will not running out of work in 2011. See ….Read More
Important RHN Satellite 5.4 bugs has been fixed
Red Hat recently released some bugfixes for the RHN-Satellite version 5.4. They needed approx. one month to develop a fix for those serious bugs. If you upgraded to sat540 before those bugsfixes have been released you will have a crippled database. The errata provides a way how to fix it. It needs some time, but it works perfectly. For “my” satellites it was taking about 48h for both satellites, about 12h for the master and 36h for the slave satellite. ….Read More
Pulp, what is it about it?
Thanks to Máirín’s posting I got aware of the Pulp project. What is it? I had a brief look at it, it is a Red Hat sponsored project with a similar functionality like Spacewalk and RHN Satellite. This brings me to the question: Is Pulp is intended to be a replacement of Spacewalk? It can make sense, it is written in Python as Cobbler is. Cobbler and Spacewalk are not really playing nice together. Spacewalk used Java, Perl and Python. ….Read More
