Microsoft piracy police target honest consumers

Author: JT Smith

NewsFactor Network writes: “It is not uncommon for many computer buyers to lose their documentation and product recovery software after purchasing their machines. Because of this, I’ve noticed that some product recovery CDs sell for a good price on EBay, especially when they are no longer available from the computer manufacturer. Like many others, I experienced this problem, so I ended up listing the product recovery CD for my HP OmniBook 500 on EBay. After my auction had been listed for about a day and a half, I got a message from EBay saying that it had been asked by Microsoft to end my auction because I had violated one of Microsoft’s “Verified Rights Owner” (VeRO) policies. Immediately afterward, the auction was removed from the site without a trace.”

Intrusion software maker snorts at security alert

Author: JT Smith

Anonymous Reader writes: “The developer of Snort, a popular open-source intrusion detection system (IDS), downplayed reports of a security flaw that could enable attackers to disable the software. According to an alert released Monday by Internet Security Systems (ISS), Snort versions 1.8.3 and earlier are susceptible to a denial of service attack.””If launched successfully against a Snort-protected network, all IDS functionality may be disabled until Snort is manually restarted,” said ISS in its alert.

ISS, which markets a commercial IDS product named RealSecure, stated that Snort’s default configuration does not have the ability to restart when it crashes and requires a separate script or process monitor for such functionality.

The flaw in Snort was originally reported by a user named Sinbad Jan. 10 on the Bugtraq security mailing list, along with instructions on how to cause the software to crash and exit.

Martin Roesch, Snort’s developer, was not immediately available for comment.

A message posted Monday by Roesch to a mailing list for Snort users noted that the denial of service attack is only successful on Linux-based Snort installations that have a feature called ASCII payload dump enabled.

“I think someone at ISS is putting together some marketing (fear, uncertainty, and doubt),” wrote Roesch, who also pointed out that instructions on how to patch the program were posted to both the Bugtraq and Snort lists on Jan. 10.

After one Snort user responded that the software’s download site contained no mention of the security vulnerability, a message was posted today on the front page of http://www.snort.org with a link to the Bugtraq post.

According to the Snort Web site, Snort is a lightweight network intrusion detection system, capable of performing real-time traffic analysis and packet logging on IP networks. The software is available for Unix, Macintosh, and Windows platforms.

The Snort site is at http://www.snort.org .
The Bugtraq report is at http://www.securityfocus.com/archive/1/249340 .
The ISS alert is online at http://xforce.iss.net/static/7874.php .

Linux Labs introduces another first for Beowulf

Author: JT Smith

By using the Dolphin PCI-ICS adapters with Linux Labs’ updates to the MPICH libraries, Scyld/Beowulf goes to the next step of using Bproc, the Scyld unified process control program, over its 800 Megabyte/Sec backplane.

Some good reasons not to use Linux

Author: JT Smith

– by Robin “Roblimo” Miller
Some people can use Linux, and some can’t. No matter how many Linux zealots talk nasty about Windows or Mac users or say that Linux is wonderful, not everyone can do their work in Linux.

Start with desktop publishing [DTP]. This is one of the most common computer tasks. Small companies, home-based entrepreneurs, schools, churches, synagogues, mosques, community centers, amateur sports leagues, and all kinds of groups use computers to make letters and letterheads, business cards, envelopes, newsletters, fliers,forms, and many other kinds of printed matter. For many people, businesses, and organizations, this is the primary reason to buy a computer in the first place.

Go to any store that sells computer software. Desktop publishing software is all over the place, ranging from little $10 utilities that make nothing but greeting cards up to full-featured DTP programs that will make almost any kind of “home made” printed material anyone is likely to need or want. Buy pre-scored sheets of business card stock from companies like
Avery, and they’ll also provide software that’ll help you use their products. Note, too, the link to the Microsoft Office Template Gallery. There is no link to a StarOffice or OpenOffice template gallery. There are special-purpose print templates around for StarOffice, but they are neither extensive nor, in my experience, very usable.

Perhaps OpenOffice and StarOffice 6.0 will, one day, have simple ways to make things like newsletters and business cards, but that’s “one day,” not today. As for professional-level publication layout and graphics, tools like Quark Express and Photoshop simply outstrip anything available for Linux. There are projects under way to make professional-level publication layout possible in Linux, but today there is nothing. (The Gimp is fine for online graphics. I use it myself, and I like it. But no matter how many Linux people say it is as good as Photoshop, it is not useful for professional-level print image manipulation.)

In general, when it comes to anything that is going to be printed on paper, Linux software is not “there” yet. It is easy for people enmeshed in the Internet culture — the kind of people who read and post comments on this site, for example — to forget that a lot of the world still runs on paper, and is likely to keep running on paper for some years yet. And printing in Linux is still limited. Yes, you can turn out basic work on the average inkjet, and a few laser printers have passable support on Linux, but when it comes to professional-quality printing, Linux is still marginal.

Let’s not talk too much about scanners, either. Linux scanner support is better than it was even a year ago, but still isn’t quite at the level of ease you get with Windows or Mac, and the selection of scanners that work with Linux is limited. Cheapie parallel port ones that a lot of people already have generally won’t work in Linux.

The curse of the Winmodem
If you install Linux on the typical store-bought PC or laptop, chances are your modem won’t work. You’ll need to buy another modem, not necessarily one that says “Linux Certified” on the box, but one that claims it’ll work not only with Windows but also DOS, at least. There are a few Windows-only modems, or “Winmodems,” that can be made to work in Linux, but not many. Just face the fact that if you want to switch from Windows to Linux, you will probably need to buy and install a new modem. And if you are in the habit of using AOL instead of an ISP, you will need to switch to a regular ISP, too, and lose that precious AOL email address and access to all those groovy AOL chat rooms where FBI agents pretend to be horny 14-year-old girls.

If you decide to get cable Internet or DSL, you will find that hardly any of their suppliers have just-fire-up-a-CD connection software for Linux. Sure, you can make Linux work with cable or DSL, but you will have to think. It’s easier with Windows. Sure, Mandrake and other Linux distros make it easier to secure your computer against hackers than Windows does, but Linux won’t let you play with Windows-based viruses and worms and spread them to all your friends. Come to think of it, neither will a Mac. If you enjoy the thrill of strangers messing up your hard drive, Windows is your best bet — and you won’t have to change a modem or anything to make it work.

Games
If your computer is a toy, not a work tool, Linux will put a lot of limits on you. There are a few Linux games around, but nothing like the shelves full of Windows games you see in most stores that sell software.

Other special-purpose programs
CAD for Linux is primitive, 3-D CAD almost nonexistent. There are special design programs for everything from office buildings to circuit boards, and most of them are available only for Windows. Video and audio editing software for Linux is out there, but very limited. There isn’t a whole lot of kid-level educational software for Linux, either, although this lack can be made up by using some of the many excellent educational Web sites that work as well in Linux as in Windows.

As a general rule, if there is a special-purpose program you are used to using in Windows, you won’t find a Linux equivalent — unless you are a scientist, engineer, ham radio operator, sysadmin or computer programmer. In these fields, Linux software abounds. On the other hand, there is a dearth of Linux software for insurance agents who want to generate quotes rapidly from many companies. Since most Linux programs are written by people who want them for their own use, this is logical. More engineers than insurance agents are likely to have the ability to write software. Of course, with all the recent layoffs in high-tech industries, it is possible that some engineers and programmers will drift into insurance sales and decide to write Linux software that will help them be more successful in their new line of work. But don’t hold your breath.

The upshot
Like it or not, there are a lot of things Linux can’t do right now, so there are a lot of people whose only rational operating system choice is Windows or, in the case of some art-types, Mac. This doesn’t mean these people are morons, lusers or idiots, or that they deserve to be cursed or sneered at. And some of the nastier teenage Linux zealots may someday find that many Windows and Mac users are girls, possibly even attractive girls, and that it is possible to have a mixed-OS relationship if they can stand a little heat from their #LinuxR00ls IRC buddies. But these lost boys are not going to get very far with girls who use Windows or Mac if they don’t quit with the insults, already.

I use and like Linux. I can do everything I need to do in Linux, but I also accept the fact that there are some things I would like to do with my computer, but can’t do as long as I stick to Linux. I am willing to make sure any hardware I want will work with Linux before I buy it, which is another inconvenience Windows users don’t usually experience. I am willing to forego the pleasures of Outlook and Outlook Express, which are not available for Linux, including the thrill of clicking on “mystery” email file attachments and having them create fun-to-solve problems with my computer. I accept these deficiencies as part of the Linux experience, just as I have learned to accept the fact that it is possible to make a fully-functional, work-ready Linux system without spending a dime on software, instead of supporting the economy by spending lots of money like a good American.

There are many places I’d like to see Linux used more, especially in government offices where my tax money is paying for expensive Windows software in many places where free or low-cost Linux software would do just as well. But I am not a Linux zealot or bigot. I recognize that there are people and companies that would rather pay through the nose for Windows and proprietary software, even if Linux equivalents are available, rather than change a modem. Sure, you can argue that it’s a lot easier and cheaper to change a modem and move to Linux than to buy a new computer or do a major hardware upgrade to run resource-hogging Windows XP, and I’m sure some people and companies understand this. But I don’t look down on those who don’t, any more than I look down on people who buy lots of lottery tickets even though state-run lotteries are one of the worst possible ways to invest your money.

And, just perhaps, some people don’t use Linux because they don’t want to be associated with foul-mouthed juveniles, like the ones who dominated this series of comments. There were some nasty Windows users in this conversation as well, but almost every time Linux is mentioned online, a bunch of Linux zealots seem to jump in with obscenties and insults so vile that I wonder if they aren’t being paid to do this by commercial operating system publishers. If so, those commercial OS publishers are certainly getting their money’s worth, because associating Linux with rotten manners makes a lot of people leery of letting Linux in their front door, let alone using it to run their computers.

Linux a penguin in shining armor for IBM servers

Is Linux the New Latin? (Live from LinuxWorld)

Author: JT Smith

From Netslaves.com: “Looking around at the
attendee crowd and the exhibitors, I’ve come to a conclusion about Linux and open source software in general:

Linux is the new Latin.

In medieval times, there were two predominant languages in any region-the local language or ‘vulgate’ and Latin,
which was used by the ruling elite at the time. All Church and legal documents were written in Latin. This had two
results: Anyone important could read them, and your average peasant never could.”
