We observed a strange difference between version 1.2.1 and version 2.0.2 in mounting file systems via NFS. In the earlier version, (v 1.2.1) mounting a file system via NFS is easy and works perfectly, and in the later, we have big trouble. —Gerard Rozsavolgy Slackware 2.02
Basically, NFS used to be broken on Linux, but it is no longer. The latest kernel versions and NFS daemons should all work well together. You should seriously consider upgrading all the machines in question. In addition to the major bug fixes, NFS is a lot faster now. —Steven Pritchard President Southern Illinois Linux Users Group firstname.lastname@example.org
I have heard that IMAP supports on-line mail processing. Is there an IMAP for Red Hat? Where can I get it? —Nga Nguyen
Red Hat has shipped the IMAP package for quite some time. It should be in the imap RPM on the CD or FTP site from which you installed Red Hat. You can use rpm or glint to install the package, and it should work out of the box. —Donnie Barnes Red Hat Software email@example.com
I'm interested in writing drivers for a device not yet supported under Linux. Where can I find books or documentation on Linux device driver development? —Sury Slackware 1.3.20
Your best sources for information are probably the Linux kernel source and the linux-kernel mailing list (to which you can subscribe by sending e-mail to firstname.lastname@example.org with “subscribe linux-kernel” in the message body. —Steven Pritchar President Southern Illinois Linux Users Group email@example.com
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
