You need to use the control panel. It is an X-based set of utilities. The control panel will start automatically if you do a startx as root, or you can do a su, set your DISPLAY environment variable, and then run control-panel. In particular you want to run the Network Configurator (netcfg) and possibly the Kernel Configurator —Donnie Barnes, Red Hat Software firstname.lastname@example.org
How can I change the name of the output file after compiling my source code with g++? I don't have the manual entry for this command. —Kennie Jose Cruz
To change the name of an executable created by g++ or gcc, use the following command: —Rafael Rodrigues Obelhei email@example.com
You can find this information in the gcc info files which should be accessible by typing info gcc, or in a shorter version by typing —Ralf Stephan
Where can I find out what changed between Linux kernel versions? —Koen Rosseau
Check out the Kernel Change Summary at ftp://ftp.shout.net/pub/users/mec/kcs/. This covers the 1.3, 2.0, and 2.1 series kernels. —Matt Hartley firstname.lastname@example.org
When trying to run xterm under X, I get the error message no ptys available. I have used Slackware in the past and have never had a problem with xterm before. —Thomas Granger
Most likely some of your pty device files got messed up. Check in /dev and restore them with mknod or —Bert Vermeulen email@example.com
Where do I find a bootp server software and directions on how to install it? —Carl Fritch
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
