Migrating from CentOS6 to RHEL6

There are different tutorial on the net how to migrate from RHEL to CentOS but almost no information about the other way round. It is quite simple and at the end of the day you have only Red Hat Packages installed. you need to copy the following packages from a Red Hat medium and install them: yum localinstall \ rhn-check-1.0.0-87.el6.noarch.rpm \ rhn-client-tools-1.0.0-87.el6.noarch.rpm \ rhnlib-2.5.22-12.el6.noarch.rpm \ rhnsd-4.9.3-2.el6.x86_64.rpm \ rhn-setup-1.0.0-87.el6.noarch.rpm \ yum-3.2.29-30.el6.noarch.rpm \ yum-metadata-parser-1.1.2-16.el6.x86_64.rpm \ yum-rhn-plugin-0.9.1-40.el6.noarch.rpm \ yum-utils-1.1.30-14.el6.noarch.rpm \ sos-2.2-29.el6.noarch.rpm \ Then ….Read More

Kernel 3.5.3 partially broken for virtualization

Some time ago, Fedora 17 got a Kernel update to 3.5.3-1. Since then, PXE booting virtual machines does not work anymore. It seems that it has not been fixed in the upstream Kernel, but only the 3.5 series of Kernels is affected. A bug has been filed, but no fix is available. The only solution for now is to stick to Kernel 3.4.5-2. I’ve checked the Fedora annouce mailinglist, looks like there have been no grave bugfixes since then. The ….Read More

How to get a RTL2832U based DVB-T stick working on Fedora 17

This week I bought a no-name DVB-T stick with the risk to not getting it working with Linux. The device contains a RTL2832u chip which seems to be quite common according to this list. The price tag was just €14, so I was taking the risk. First experiments shown that there is no chance to get it running on Fedora 17. After digging deeper I figured out that someone wrote a driver and published it on github. Later on, I ….Read More

How to transfer files to the Google Nexus 7

It looks like a silly question, but it is not. The device does not support USB Mass storage, but some stuff called MTP. Unfortunately it does not work as expected with Linux. The first try was to yum -y install libmtp.x86_64 libmtp-examples.x86_64 and mount the device with fuse: mtpfs /mnt. However, it seems it is not mature enough yet to use it. If you just want to put some sound files on to your device, Amarok works pretty fine. But ….Read More

Retrospection to FOSDEM 2012 Brussels, Belgium

This year I made it, It was my first time at FOSDEM, the Free and Open Source Developers European Meeting. I was amazed about the crowd of people and the amount of talks. It was simply impossible to visit all interesting lectures, because lots of them has been held in parallel. It was also a pleasure to meet again all those people I know from the open source communities. The Friday beer event was very nice, as well as chatting ….Read More
