Best of Technical Support
I currently have a TCP/IP (via modem) connection between my Linux box at home and my office workstation (DEC station running Digital UNIX). The problem is that the DEC machine is not a gateway, so I cannot reach the rest of the subnet or the rest of the world, for that matter. Is there a way my Linux box can reach the subnet gateway which is two hops away? The route command in my current version of Linux (Slackware, kernel 2.0.0) does not support the -hobcount flag, which is supported by Digital UNIX and would do the trick. —Martin Olivera, firstname.lastname@example.org
If your PPP IP address is one from the subnet your DEC station is sitting on, you just need to make sure it does ARP proxying for your Linux machine (in other words, it has to accept packets for your Linux machine's IP on its local Ethernet). If this is not the case, then it is more difficult. The options you have are:
Find out if Digital UNIX can do IP masquerading like Linux can.
Configure routed on your DEC server and advertise a route pointing to your Linux machine. Note that this will not work if your default gateway ignores RIP information, and it may upset your network administrator and/or be against company policies.

As a Spanish speaker, I want to use a keyboard with a complete set of Latin characters. I succeeded in implementing it for almost all applications, except Netscape. I installed the XKeysymDB file in the correct place, and this file works properly for Sun machines (I tested), but not for PCs with Linux. I tried to find the answer at Netscape's home page, but I couldn't. Perhaps I did the wrong search. Does anyone know how to set Netscape in order to have a “compose” key which produces accents, tildes and all that sort of thing? —Guigue, firstname.lastname@example.org
If I'm not mistaken, the XKeysymDB file works only for a particular keyboard, so the one that works for your Sun keyboard is unlikely to work for your Linux machine's keyboard. Jamie Zawinski's xkeycaps found at http://www.jwz.org/xkeycaps/ may help; it is a graphical editor for editing keyboard setups under X. —Scott Maxwell, email@example.com
I got interested in Linux through a programme on BBC World. However, after an afternoon roaming the Internet, I couldn't get an answer to two questions most laymen probably have on the subject: does Linux replace Windows on my computer and is the process irreversible; will I be able to use my Windows-based programmes on Linux? —Philippe Humblé, firstname.lastname@example.org
Linux can replace Windows on your computer, or the two can coexist. If you buy a commercial distribution or a Linux book, it should help explain how to do this. The process is irreversible only in the sense that you'll never want to go back. There are different ways to use your Windows-based software under Linux. A couple of emulators—Wine and Wabi—enable you to run some Windows software directly under Linux. (Similarly, DOSEMU lets you run DOS software under Linux.) Other Windows software can be run by rebooting the machine into Windows, using the software, and then rebooting into Linux again as soon as possible. As time goes on, you'll discover Linux software that can partially or entirely eliminate your need for Windows—Linux-native word processors, spreadsheets and such. —Scott Maxwell, email@example.com
I am new to Linux and have heard much about the X Window System when word processing using Applixware Office or Corel's Word Perfect for Linux. What if I don't want to use X? Are there quality office applications that will run without X?<\n> —John Tam, firstname.lastname@example.org
There is not, as far as I know, a non-X integrated office suite, but many of the pieces exist. For document processing, you can use TeX. Whether you'll like TeX or not depends on your needs—it is rock-solid and extremely powerful, but it is not WYSIWYG. —Scott Maxwell, email@example.com
Most people associate “quality office applications” with “graphical user interface”, a “what you see is what you get” environment like the current flock of office applications shipping for Windows machines. On UNIX systems, the standard GUI environment is the X Window System, so all of the current office suites for Linux run on top of X. This makes life much easier for the programmer—she can concentrate on writing a good word processor and leave the details of making it “graphical” to X. Early versions of X were somewhat tricky to set up and supported only a small subset of available graphics cards, but the configuration programs have come a long way as has driver support—a quick read of the X HOWTO should leave you with nothing to fear from “getting graphical” on your Linux machine. —Vince Waldon, firstname.lastname@example.org
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
