If you learn Linux so command line looks little bit scary for you.

The solution could be summary of base Linux commands. So you never again wonder what was the command that do……?

Finally it is out and until Monday It should be synced to all mirrors with iso’s available for download.

Release notes

If you do not have fast connection you can buy it on CD ot DVD from our store

My Experience

After 450M download (186 packages) here are first problems:

In my setup sysreport package (from rpmforge) conflicted so I just removed it and installation went OK. Later I saw it was replaced by sos package.

New kernel welcomed me with new message:

“Memory for crash kernel (0x0 to 0x0) notwithin permissible range”

To be honest I’ve seen the same message in RHEL 5.1 so I expected it.

Next thing was that redhat-release was still with version 5?

Will wait for day or two before bringing this as bug (it is possible that the repo was no fully synced)

No other problems for now….

After browsing mirrors I was surprised that finally there is netinstall CD.


“Memory for crash kernel (0x0 to 0x0) notwithin permissible range” is harmless message

This update is strongly recommended.

It fixes following security flaws:

MFSA 2007-39 Referer-spoofing via window.location race condition
MFSA 2007-38 Memory corruption vulnerabilities (rv:
MFSA 2007-37 jar: URI scheme XSS hazard

But this is not all….

When restarting Firefox to apply the update I was surprised with the message that I cannot install the update because I’m not an owner of the file or do not have administrative privileges…..

After several retries I realized that there is another user logged on my PC and it was using Firefox 🙁 after closing this extra copy update was installed and now I use latest version.

Update of the update:

The release fixed some 200 issues, but accidentally regressed a few things. Most users won’t see any difference or experience any problems, and those 200 fixes make the update very valuable, but you should never have to choose functionality over security. So we’re working fast to understand and fix these problems, and will shortly be issuing a update to address them. The specific problems are:

  • Bug 400406 – Firefox will ignore the “clear” CSS property when used beneath a box that is using the “float” property. There is a temporary workaround JS/CSS code available for web developers with affected layouts.
  • Bug 400467 – Windows Vista users will get “Java not found” or “Java not working” errors when trying to load Java applets after updating. To fix this, users can right-click the Firefox icon and “Run as administrator”, then browse to a page with a Java applet — doing this once will fix the problem and permanently restore Java functionality.
  • Bug 396695 – Add-ons are disabled after updating. Users can fix this problem by opening their profile folder and removing three files (extensions.rdf, extensions.ini and extensions.cache)
  • Bug 400421 – Removing a single area element from an image map will cause the entire map to disappear. There is no workaround available at this time.
  • Bug 400735 – Some Windows users may experience crashes at startup. There is no workaround available at this time.

Recently scientists discovered the power of Sony PlayStation 3.

But not to play games, but to crunch numbers.

Gravity project utilizes 8 PS 3 running Linux – connected in cluster to replace 200 Supercomputer nodes.

Overall, a single PS3 performs better than the highest-end desktops available and compares to as many as 25 nodes of an IBM Blue Gene supercomputer. And there is still tremendous scope left for extracting more performance through further optimization.

Rack of PS 3s

This “mini” supercomputer is used to help measure these theoretical gravity waves – ripples in space-time that travel at the speed of light that Einstein’s Theory of Relativity predicted would emerge when such an event takes place.

Many users still do it the old fashion style.

  1. Open terminal
  2. CD to the directory

Now the shortcut:

  1. Right click desired folder in Nautilus and choose Open in terminal

It is simpler and saves some typing. Requires that nautilus-open-terminal package is installed.

Google is adding more apps to his Linux repository.

They also have script to setup repositories, but unfortunately it does not recognize CentOS and yum enabled distribution. I’ve added this code to check if yum is installed:

# Check if yum is installed RHEL v5 and CentOS 4.x and 5
if [ '/bin/rpm -q yum' ]; then

Resulting script is here:

Google repos for centos

NOTE: After downloading the file just rename it from .txt to .sh and run with the shell:

bash google-repo-setup_CentOS.sh

Currently you can find there only picasa and google desktop

I use wine from rpmforge repository.

It works well, but all system (bitmap) fonts are missing. DAG could not confirm this as bug, but several other CentOS users confirm that this problem exists.

How to fix:

Install wine (You need rpmforge repo enabled)

yum install wine

Install msttcorefonts

Follow these instructions

move /usr/share/wine/fonts to fonts.old (if already exist remove c:\windows\fonts folder too)

cd /usr/share/wine

mv fonts fonts.old

It is done.

You can use wine and all fonts appear.

Recently site http://apt.sw.be/redhat/el5/en/mirrors-rpmforge went down and this broke my YUM. Here is the error:

Setting up repositories
Could not retrieve mirrorlist http://apt.sw.be/redhat/el5/en/mirrors-rpmforge error was
[Errno 4] IOError: <urlopen error (-2, 'Name or service not known')>
Error: Cannot find a valid baseurl for repo: rpmforge

As a solution I’ve edited manually my /etc/yum.repos.d/mirrors-rpmforge

vi /etc/yum.repos.d/mirrors-rpmforge

And commented out problem site.

Then edited /etc/yum.repos.d/rpmforge.repo

vi /etc/yum.repos.d/rpmforge.repo

And commented live list and uncommented file. Like this

#mirrorlist = http://apt.sw.be/redhat/el5/en/mirrors-rpmforge
mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge

Now YUM it is back. Still get some mirroring errors, but at least I can use it.
