Recently, several attempts to run vi /etc/filename resulted in vi freezing and Telnet/SSH not responding to break commands (Ctrl-C, Ctrl-B, Ctrl-D). I logged in to the server again and tried to kill the process. The man pages said that if kill didn't work, it was probably a result of the kill command being a part of the shell. So I tried /bin/kill <pid>, /usr/bin/skill <pid>, /usr/bin/killall vi with 9, 15 and several other signals. Running top and killing the process via top didn't work either. It has been a couple of days and about a dozen vi processes are still running. I need a license to kill!

If a process is stuck in kernel state due to a kernel or network problem, you will not be able to kill it, even with kill -9. In that state, you can usually only reboot to get rid of the process.

Why can I not get startx to work on a Toshiba Satellite Pro 4600 that uses a Trident CyberBladeXP video card? I am running Red Hat 7.2., and I get the following error:
Fatal server error: No Valid modes found.
There is one update from Red Hat's site that mentions solving a problem with your video card. Please try to upgrade the necessary packages and try again. You can find more information about it at rpmfind.net/linux/RPM/redhat/updates/7.2/i386/Xconfigurator-4.9.39-2.i386.html.

When I run DragonLinux everything loads perfectly until Space Freed:. Then it says:
Warning:Unable to open an initial console Kernel Panic:no init found. Try passing init= option to kernel.

You may have corrupted the root filesystem after you finished installing. I suggest that you reinstall Linux and make sure that you make a filesystem on all Linux partitions. If you experience the same problem again, then you need to contact the DragonLinux people.

I thought I'd take the opportunity to e-mail you about configuring Red Hat 7.0 to be able to use Japanese. I have a 109-key Japanese keyboard and am using a Japanese 106 keymap that works okay, despite being unable to use the Japanese-English switch key. I enabled deadkeys and installed all the Japanese language packets during installation. These packets, WNN and Kanna packets, among others, start up on boot but don't activate for some reason. Any help would be appreciated. I think I could solve it by getting the right keyboard map. Japanese characters will appear on most software in KDE and GNOME, but getting output from the keyboard is the problem.
—Graeme Jensen, firstname.lastname@example.org
I recommend you use a distribution that has been widely tested with Japanese. You'll have better odds with those things working out of the box. I have to admit I'm not sure which is the Japanese distribution of choice today, but you may want to give Turbolinux a try.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
