I want to be able to change both the initial message displayed when a user opens an FTP connection to my system and the login message. I know this is supposed to happen in ftpaccess, but I can't for the life of me find the files referred to in the configuration files /welcome.msg and .message. Is it that these files simply don't exist, and the messages displaying are defaults? Help. —Jon Dewey, firstname.lastname@example.org
These files exist in your anonymous ftp area. On Red Hat this is usually /home/ftp. If you place a text file called welcome.msg in that directory, it will appear when someone anonymously logs into your machine. —Christopher Wingert, email@example.com
I can't install Linux due to an MBR problem and the message RAMDISK: Compressed file at block 0.
I have tried to cfdisk but no luck. I tried all sorts of boot/rescue diskettes without luck for two years now.
How can I wipe this hard disk clean before I install RHLinux? —Joseph Lalingo, firstname.lastname@example.org
You can wipe the MBR with lilo -u. —Christopher Wingert, email@example.com
I installed Red Hat 7.0 as a dual boot with Windows 98 on my Toshiba laptop. Now when I boot, I am unable to get to either operating system, just a series of bracketed numbers, and the following message:
Code:89 02 85 c0 74 03 89 50 04 b8 01 00 00 00 eb 03 90 31 c0 c7 Aiee, killing interrupt handler Kernel panic: Attempted to kill the idle task! In interrupt handler - not syncing
I am unable now to boot from diskette or CD-ROM. —Neil O'Connor, firstname.lastname@example.org
Boot your laptop using the rescue floppy created at install time, and run /sbin/lilo. This will reinstall LILO, and you should be able to boot from the hard disk again. —Usman S. Ansari, email@example.com
Practical Task Scheduling Deployment

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
