Lexar LDP-200 Digital Music Player is Multi-platform

Mike Angelo writes: "Digital music players are very popular these days and are available from many manufacturers. One nice feature of the Lexar Digital Music Player (LDP-200) is that it uses SD memory cards to store the music files, thus providing it with almost unlimited memory. Another nice plus for the Lexar Digital Music Player is that you can use it with most all popular, desktop operating systems -- the GNU-Linux, Mac, and Microsoft Windows platforms."

[Nice price, multi-OS, and multi-purpose! Warning: only tested on Mandriva, but they're probably right about it working with most other *NIX variants - Ed]

Replacing ms dns with bind9

Replacing ms dns with bind9 is an better idea here is why:
1.It's really faster (noticed when i run first query on that machine and had lower latency)
2.Better security (windows2k is not supported with patches in future)
3.You can migrate easily to linux after that ;)

[Ed.- This is a good quickstart. Please do the Internet a favor and study the BIND documentation thoroughly.]

Hacks From Pax: SELinux Administration

  • LinuxSecurity.com - Feature Stories; By Pax Dickinson (Posted by tuxchick on Nov 7, 2005 11:16 PM EDT)
  • Story Type: Tutorial
Hi, and welcome to the third in a series of articles on Security Enhanced Linux. My first SELinux article detailed the background of SELinux, while my second article in the series discussed how SELinux makes access decisions. This week, I'll talk about how an SELinux system differs from a standard Linux system in terms of administration. Most of what you already know about Linux system administration will still apply to an SELinux system, but there are some additions and changes that are critical to understand when using SELinux.

An Introduction to MySQL, LAMP Stack and Microsoft Windows ...

When open source software is mentioned, one of the first thoughts that comes to mind is the LAMP stack (Linux, Apache, MySQL, and PHP/Perl/Python). While these products are not generally associated with Windows development, at least one of them is certainly well suited for Windows development, particularly when using .NET. The MySQL database server is an open source relational database developed by MySQL AB. MySQL is available for Windows, Linux, UNIX, and the Macintosh operating system. Using MySQL with Windows has never been easier with .NET and ADO.NET.

(Mandriva) Background: Linux software repositories and software installation

This section is aimed at all those who have no or limited Linux experience, and are unfamiliar with software repositories. It occurred to me that novice Linux users are often at a loss where to get software, and the next thing that happens is that they manage to find some rpm file somewhere on the internet, and run into what is aptly called 'dependency hell' (for Linux insiders: note the pun! Ah well, I'm not good with those anyway..). So I decided to put up a couple of paragraphs about software installation, and clear up a few puzzling points.

[Ed.- great article- only please, for the love of $deity and readability, lose the text-scrolling-over-fixed background. Ow.]

Avoiding Oblivion in Your Tech Career

  • O'Reilly Network; By Mike Havey (Posted by tuxchick on Nov 6, 2005 8:28 AM EDT)
  • Story Type: Tutorial
Where are you headed in your technology career? If Shakespeare is correct in his renowned soliloquy on the seven phases of life in As You Like It, you stand to lose your sense of taste, your eyesight, and your teeth. Life moves quickly for the technologist: one day, you're a reticent rookie whose broken code generates core dumps; the next, you are the center of attention and the slickest talker in the design review session. But ultimately, you fade into old age and fall apart like some antiquated IT system: a curious relic with no value and in need of maintenance.

[Ed.- Don't let the lead scare you- the author tells how to avoid becoming old, toothless, and unwanted. At least in your career.]

Networking 101: Understanding IP Addresses

  • Enterprise Networking Planet; By Charlie Schluting (Posted by tuxchick on Nov 6, 2005 6:34 AM EDT)
  • Story Type: Tutorial
Networks don't work without addresses: Whenever you are sending something, you need to specify where it should go and where it came from. To be an effective network engineer or administrator, you need to understand IP addresses backward and forward: you need to be able to think on your feet. If something breaks, likely as not some address assignment has been screwed up. And spotting the problem quickly is likely to be the difference between being the hero, or the guy who "takes a long time to fix the problem." Before covering subnetting in the next Networking 101 installment, we'd like to thoroughly explore IP addresses in their primal form. This is crucial to understanding subnets.

[Ed.- This should be a great series. Stay tuned for more.]

Redundant Internet Connections Using Linux

  • SysAdmin Magazine; By Seann Herdejurgen (Posted by tuxchick on Nov 6, 2005 2:06 AM EDT)
  • Story Type: Tutorial
With the advent of high-speed Internet links from Internet Service Providers (ISPs), it's easier for users to host services on their home computers. But what happens when your ISP connection goes down? An obvious solution is to have a redundant Internet connection from another ISP. To help set up a Linux host with redundant Internet connections, this article covers the following essentials:

1. Configuring the host to properly handle inbound network connections from multiple ISPs

2. Load-balancing outbound network connections

3. Configuring various services to enable redundancy

4. Configuring firewall protection using ipchains or iptables

[Ed.- Linux has all the tools to implement just about any kind of networking scenario- you don't need to spend megabucks on pricey commercial widgets.]

Setting up your own APT repository with upload support

  • Debian Administration; By Steve Kemp (Posted by tuxchick on Nov 5, 2005 10:17 PM EDT)
  • Story Type: Tutorial; Groups: Debian
We've previously covered setting up your own repository for the Debian's apt-get system, but we didn't cover managing automatic uploads. Thankfully this is a simple task with the reprepro, and dupload tools and a small amount of scripting.

The reprepro package is tool for creating an APT repository with a pool structure, the same type of structure the official Debian mirrors use.

The repository may:

Contain packages for multiple distributions: Stable, Unstable, Testing, etc. Contain packages for multiple architectures: x86, sparc, all, etc. Be managed quickly and easily.

AJAX and scripting Web services with E4X

E4X is an extension of JavaScript that adds direct support for XML to the language. So what is direct support and why is it valuable? Get an introduction to ECMAScript for XML (E4X), a simple extension to JavaScript that makes XML scripting very simple.

Internet Explorer is dangerous

4 out of 5 Internet users use Microsoft Internet Explorer as their web browser. Internet Explorer presents a critical security risk to systems that use it, allowing malicious websites to hijack their computers, infect them with viruses, and conduct identity theft. It is in the best interest of all Internet users to stop using Internet Explorer as soon as possible! There are free alternatives that offer quality as good or better than Internet Explorer. The following article will explain in greater depth the problems with Internet Explorer and what the alternatives are.

[Ed.- This is an excellent comparison and analysis that compares aieee I mean Internet Explorer, Firefox, and Opera. It even has pretty graphs comparing the number and severity of vulnerabilities and time-to-patch. Very good even for non-technical users and decision-makers.]

Postfixing your mail server

  • Ars Technica; By Ryan Paul, Ian Smith-Heisters, Matt Mondock (Posted by dcparris on Nov 3, 2005 7:21 AM EDT)
  • Story Type: Tutorial
Years removed from the original release of Postfix, the Unix-based mail server is still serving oodles of people every day. As a great alternative to Microsoft Exchange and the predecessor to crazy uncle Sendmail, Postfix is becoming the Linux mail server of choice, and is the SMTP mail transfer agent for Mac OS X Server. Sendmail may have a larger market share in the Linux community, but Postfix has a much simpler setup and is good for users who do not want to spend a lot of time configuring a mail server.

Replace Your NT4 Domain Controller with Samba 3

  • Enterprise Networking Planet; By Carla Schroder (Posted by tuxchick on Nov 1, 2005 9:33 AM EDT)
  • Story Type: Tutorial
It's official: as of December 31, 2004, Windows NT4 is no longer supported by Microsoft... For all of you hardworking sysadmins of NT4 domain controllers who are now wondering what to do, here are some of your options:

1. Change nothing. So you lose vendor support — so what? Was it so hot in the first place?
2. Upgrade to Windows XP or 2003. This costs much money in licenses, and you may need to upgrade your hardware as well. Plus you'll have a whole new set of bugs and security holes to get acquainted with. However, this also gives you Active Directory, which may be something you want to move up to.
3. Replace your NT4 box with a Samba 3 domain controller.

This series is about option 3...

[Ed.- Yes, this is an older article, but it's still a goodie. Part 2 is here.]

Modern Memory Management

  • OnLamp.com; By Howard Feldman (Posted by tuxchick on Oct 31, 2005 1:37 AM EDT)
  • Story Type: Tutorial
Despite this enormous increase in memory capacity, many of the problems that exist on today's machines are the same as those of their early predecessors--namely, running out of memory.

This article, the first in the series, discusses the Unix dynamic memory allocation system along with the concept of memory segmentation. It also reviews the utilities top and ulimit, giving special attention to their role in memory management. Memory management is an important concept to grasp regardless of which programming language you use. You must be most careful with C, where you control all memory allocation and freeing. Languages such as C++, Java, Perl, and PHP take care of a lot of the housekeeping automatically. Nevertheless, all of these languages and others can allocate memory dynamically, and thus the following discussion applies to them all

And how would you like to have everything logged, so you can "go back in time" and review past events? These are just some of the things conserver can do for you.

[Ed.- Linux console servers, while not the most fun to use for everyday administration, can be real life-savers when everything else goes *poof*. Conserver is a free, sophisticated console server with a great feature set that takes you far beyond good ole Minicom and a null-modem cable.]

So You Want to Write a Book?

  • O'Reilly Media, Inc.; By O'Reilly Media, Inc. (Posted by tuxchick on Oct 30, 2005 3:48 AM EDT)
  • Story Type: Tutorial
If you have ever thought, even half seriously, that you would like to write a practical book about computers or computer software, then you probably can. Moreover, given the proper editorial and publishing support, you can probably write a successful book. It's all a matter of doing the right things in the right order. And it helps a great deal if you have a publisher willing to do everything in its power to help you along.

[Ed.- I write books for O'Reilly, so naturally I think they are the bee's knees. However, much of the information in this article applies to all publishing, and most publishers post similar guides on their Websites. If you think you have a book or two in you, go for it- there is all kinds of information here that will help you.]

New Use for Old Hardware: A Network Copier

  • Linux Gazette- the REAL Linux Gazette; By Edgar Howell (Posted by tuxchick on Oct 30, 2005 2:50 AM EDT)
  • Story Type: Tutorial
Basically the plan is to configure Samba on a PC under GNU/Linux such that another PC with some flavor of Windows can access a share on it. Then, the software that came with the combo device can be used on the Windows machine to scan a document, and save it on a Samba share, in a directory on the Linux machine. And from there OpenOffice.org can access the result of scanning, and print it over the network to the network printer.

[Ed.- This is an ingenious hack that kept a partially-functioning combination fax/printer/scanner/copier in service, and is easily adaptable for other scenarios.]

What Is Asterisk

Asterisk is an open source PBX (private branch exchange) that provides all the functionality of high-end business telephone systems, and much more. It is the world's most flexible and extensible telephone system, providing many features that are not yet available in even the most advanced proprietary systems. It is also the world's cheapest telephone system. The software is free and runs on inexpensive Linux servers.

[Ed.- Asterisk is teh hawt. If you've ever rented space on a shared PBX with a single master password that is never changed, or hassled with telecom techs who just don't seem to understand why you want things to work right, take your telephony system into your own hands with Asterisk.]

Learning to Program with DrScheme

  • Linux Gazette- the REAL Linux Gazette; By Pramode C.E. (Posted by tuxchick on Oct 29, 2005 10:05 PM EDT)
  • Story Type: Tutorial
The ideal programming language for beginners should offer the minimum barrier between thought processes and their concrete implementation as programs on the machine. It should not be a ‘toy’ language - its structure should be rich enough to express complex computer science concepts without being awkward. The language should encourage good coding habits and students should be able to look at it as an extension of the three things which they have already mastered to varying levels of proficiency - reading, writing and mathematics. Do we have such languages? Yes - the programming language Scheme fits in admirably.

Centralized User Management with Kerberos and LDAP

  • Sys Admin Magazine; By Travis Crawford (Posted by tuxchick on Oct 29, 2005 9:07 PM EDT)
  • Story Type: Tutorial; Groups:
Centralized management of user accounts solves a major problem in distributed computing environments. Without centralization in an environment with X users, Y computers, and Z services, we have (X*Y)+(X*Z) accounts to manage. With centralization, we have X+Y+Z accounts to manage. In this article, I will provide an overview of user account management with Kerberos and LDAP. I will describe the protocols and how they work as well as their implementation. Finally, I will discuss how to manage accounts using this new system.

[Ed.- this is a wonderfully detailed howto that clearly explains how all the pieces work, written by a Google System Administrator, so presumably he has had a lot of practice!]

The Mini-ITX Project Part II

Once my original Mini-ITX project was completed I finally had a chance to sit back and use the computer. Knowing how simple my needs were, the Mini-ITX project computer was orginally designed to be as basic and quiet as possible. This meant no hard drive, no extra accessories- just a stripped down system. While this suited my needs well at the time, its lack of versatility soon became an issue.

Marcel's Linux Game of the Month : Pingus

After spending any amount of time playing (and yes, when necessary, working) with Linux systems, you can't help but notice that penguins do tend to figure prominently in the mythos of the operating system. Penguins show up everywhere — from the Linux mascot, Tux (designed by Larry Ewing), to the numerous variations on the penguin theme, you can't go near a Linux system, magazine, T-shirt, mouse pad, coffee mug, or book, without running into some kind of penguin. That's okay for most people because, well, penguins are cute.

Marcel's Linux App of the Month : streamtuner

A long time ago (when the Earth was young), I worked as a top-40 disc jockey for a local radio station. The years have passed but my passion for radio hasn't dwindled. A few months ago, I discovered Xiph.org's icecast.org directory of music streams. Not long after that, I ran across SHOUTcast. Between these two Web sites, I had access to literally thousands of Internet radio streams, both professional and amateur, covering every imaginable musical taste. As you can well imagine, browsing through these sites can become a rather time-consuming process — not that I minded, but time is something I seem to have a lot less of these days. That's why I like Jean-Yves Lefort's streamtuner so much.
