Un-killable Processes : Red Hat Enterprise Linux

By Johnathan Kupferer, Red Hat Certified Engineer

Before Red Hat Enterprise Linux 4, there really wasn’t a good way to handle processes that had entered an
uninterruptible sleep waiting on an unresponsive NFS server. This was particularly frustrating because the
umount man page promises that “-f” will “Force unmount.” This allows an NFS-mounted filesystem to be
unmounted if the NFS server is “unreachable.” That was how it was supposed to work, with the caveat that
the filesystem must have originally been mounted with “soft” or “intr” options.Well, no more. Though the
man page doesn’t say so, umount -f now comes to the rescue and will unmount hard and uninterruptible

USB when the Drivers Aren’t Available

By Dominic Duval, Red Hat Certfied Engineer

As a way to save a few valuable pennies on newer PCs, manufacturers are increasingly getting rid of the good old PS/2 keyboard and mouse interfaces. As a result, some recent systems only ship with USB ports to which we need to connect a USB keyboard and mouse.
USB is all well and good, but what if the driver for your USB controller is not loaded? In practice, this is not a problem, as Red Hat loads the ehci- hcd and uhci-hcd drivers automatically at boot time.
There are situations, namely in emergency mode, where the USB drivers won’t be available. So you won’t even be able to enter a command. This is due to the fact that in emergency mode all drivers need to be provided in the initrd file under /boot, and USB is not there by default. The trick is to add those drivers, so that they will be available earlier. The ‘mkinitrd’ command can do precisely that with the ‘–with’ argument (this only works under RHEL4):
mkinitrd –with=ehci-hcd –with=uhci-hcd /boot/newinitrd-`uname -r`.img `uname -r`

Add a new entry in your grub.conf file (always do backups!) that points to this new initrd image, and you’re done! Your USB keyboard now works in emergency mode.

Ubuntu 7.04 Feisty Fawn Free CDs available at shipit

Ubuntu Feisty Fawn is finally available at Ubuntu Shipit, so you can ask for your Feisty Fawn Free CDs

Install Livna repository FC6

Installing the Livna repository for Fedora

rpm -Uhv

(This will download the rpm for you from the web and install it.)

Getting and installing the GPG key so the packages could be verified with its signature.

rpm –import

That is all, now you can start using the packages from the Livna repository with yum or yumex.

Wi-Fi Bug Found in Linux

A bug has been found in a major Linux Wi-Fi driver that can allow an attacker to take control of a laptop — even when it is not on a Wi-Fi network.

Ubuntu 7.04 Review

A mature Linux desktop…

Feisty boots in 40 seconds on my laptop, while Vista needs about 50 (with McAfee turned off). Additionally, Ubuntu now seems to be more usable than before with 256 MBs of RAM (with CUPS services turned off) and 512 MBs seem to be more than enough — a number that’s the minimum for Vista.

Nvidia Releases A Performance And Debug Tool For Linux

NVIDIA has, more often than not, been extremely helpful when it comes to making sure it is supportive of the desktop market. Today’s post just goes to reaffirm this, I think.

NVPerfKit is a comprehensive suite of performance tools to help debug and profile OpenGL and Direct3D applications. It gives you access to low-level performance counters inside the driver and hardware counters inside the GPU itself. The counters can be used to determine exactly how your application is using the GPU, identify performance issues, and confirm that performance problems have been resolved.

NVPerfKit 2.1 now includes support for 64-bit Windows platforms, as well as 32-bit and 64-bit Linux platforms. Other improvements include an updated installer, Release 90 driver support, enhancements to NVPerfHUD, and more.

The performance counters are available directly in your OpenGL and DirectX applications and in tools such as Intel VTune and Graphic Remedy’s gDEBugger via the Windows Management Instrumentation (WMI) Performance Data Helper (PDH) interface. A plug-in supporting Microsoft PIX for Windows is also provided, giving you low-latency access to NVPerfKit performance counters directly from the driver… [Source: LinuxLookup]

HOWTO Access A Superfast Linux Desktop From Anywhere Using FreeNX

I think this is great! Discover just how to access your desktop from just about anywhere!

FreeNX allows superfast and secure access to your Linux box from anywhere in the world. This HOWTO is a step-by-step guide for configuring the nxserver, generating custom encrypted keys, and using a combination of Live-CD and USB thumbdrive to create a portable nxclient for remote access.

0 – Start

FreeNX is the GPL-ed free software version of the NXserver technology developed by NoMachine. NX squeezes the fat and chatter out of Xsessions, making possible the use of Linux GUI desktops and applications in remote locations with extreme response over limited bandwidth. Using KDE over FreeNX with a DSL connection is a “like I was right there” experience… little to no lag at all! Even a modem connection gives up a usable computing experience.
This HOWTO uses Kanotix Linux, a Live-CD distribution that can be run entirely from CD or installed to a hard drive….. Source:

Animate the Desktop with Xgl and Compiz

t’s cooler than anything Microsoft has by far, but is it really part of a better computing experience?

To get working well, it is essential to harness the 3-D rendering capabilities of your graphics card and setup the plug-ins with the composite window manager, This excerpt is from Chapter 3: Using SUSE Linux on Your Desktop, from the book By Chris Brown PhD, published by O’Reilly Media. Reprinted with permission. All rights reserved.

Section 12: Animate the Desktop with Xgl and Compiz

Given the rapid pace of software development in the Linux world, it is inevitable that some topics that are bleeding-edge as this book goes into production will be mainstream technology by the time you get to read it. One such is the Xgl X server and the compositing window manager compiz. Together with a modern graphics card, these components (which are shipped with SUSE Linux 10.1) offer some stunning visual desktop effects comparable (dare I say this?) to the best that the Mac has to offer. These effects include transparent windows, fade-in/fade-out of windows and menus, animated window minimization, and the ability to put four desktops onto four faces of a cube and spin the cube (in 3-D) to switch desktops. The overall result is to give the desktop a more fluid, organic feel…. Source: Linux Journal
