Unix+clones Convert any video file to DVD with open source tools
Post date: April 28, 2006, 13:04 Category: Multimedia Views: 13
Tutorial quote: You've just downloaded the new episode of your favorite video podcast, and you'd like to watch it on your big-screen TV. Unfortunately, the video is encoded in XviD or QuickTime format, which your DVD player doesn't support. Don't worry -- here's how you can convert any video file to DVD using dvdauthor and MPlayer.
Linux Enhancing kernel security with grsecurity
Post date: November 25, 2005, 16:11 Category: Security Views: 74
Tutorial quote: Is your server as secure as it could be? Sure, you use a firewall, mandate strong passwords, and patch regularly. You even take a proactive approach by performing security audits with tools such as nmap and Nessus. Yet you may still be vulnerable to zero-day exploits and privilege escalation attacks. If these possibilities keep you awake at night, you're not alone. The sleepless folks with the grsecurity project have developed an easy-to-use set of security enhancements to help put your fears to rest.
Ubuntu Windows to Ubuntu Transition Guide
Post date: April 8, 2006, 11:04 Category: Miscellaneous Views: 84
Tutorial quote: Alright, so you have successfully installed Ubuntu Linux, but now what do you do with it? You are in the right place. I am going to get you started with a guide on how to use your new Ubuntu system. This transition guide is targeted at existing Windows users and will show you how to do program installations, a little system configuration, but primarily highlight some Windows "replacement" programs for common applications you can't live without. This guide's intent is to introduce you to equivalent programs to what you are accustomed to and, hopefully, to cover a good amount of what you might want in a new install. I am basing the content on what I have personally experienced, email feedback from my installation article, questions from the PC Mech Forums, and common topics from the Ubuntu Forums. Hopefully this will answer a lot of questions you may have before you ever have them.
Unix+clones Downloading without a Browser
Post date: November 29, 2005, 14:11 Category: Software Views: 55
Tutorial quote: Ever had to download a file so huge over a link so slow that you'd need to keep the web browser open for hours or days? What if you had 40 files linked from a single web page, all of which you needed -- will you tediously click on each one? What if the browser crashes before it can finish? GNU/Linux comes equipped with a handy set of tools for downloading in the background, independent of the browser. This allows you to log out, resume interrupted downloads, and even schedule them to occur during off-peak Net usage hours.
Ubuntu Essential house keeping in Ubuntu
Post date: December 8, 2005, 06:12 Category: System Views: 184
Tutorial quote: I started using Ubuntu Breezy ver 5.10 a month back on my machine. Prior to that I was exclusively into Fedora. What drew me to Ubuntu was the huge number of packages in its repositories including softwares which I find useful on a day-to-day basis like Tomboy which I had to compile from source in Fedora. But the Ubuntu CD comes with the base packages which support only open file formats. So if you want support for proprietary file formats like mp3 and quicktime support as well as install softwares not included on the CD, then you have to do some work.

I call it essential housekeeping because it is not exactly a problem, but only a matter of finding out how to get the necessary support. Here I share my experiences in putting the Ubuntu house in order on my machine.
Linux Hardening Linux: a 10 step approach to a secure server
Post date: June 22, 2005, 06:06 Category: Security Views: 156
Tutorial quote: The Internet has become a far more dangerous place than it was 20 years ago. Nowadays, Operating System and application security is an integral part of a server configuration and, while firewalls are very important, they are not the panacea.

This list of steps is intended as a guideline with a practical approach. We’ll try to provide a complete picture without getting into unnecesary details. This list won’t replace a good book on secure systems administration, but it will be useful as a quick guide.

Before we get started it’s worth to mention that security is not a status: it’s just a process. The correct initial setup of the server only provides a good start and helps you get half the way through. But you actually need to walk the other half of the road, by providing proper security vigilance, monitoring and updating.
Unix+clones Comparing MySQL performance
Post date: April 12, 2005, 03:04 Category: Benchmarks Views: 57
Tutorial quote: With the introduction of the 2.6 Linux kernel, FreeBSD-5-STABLE, Solaris 10, and now NetBSD 2.0, you might be wondering which of them offers superior database performance. In my previous article, I discussed the tools I chose to test these venerable operating systems and the methodology by which they were tested. The result is this MySQL performance comparison between OpenBSD 3.6; NetBSD 2.0; FreeBSD 5.3 and 4.10; Solaris Express (build 69); and Linux 2.4 and 2.6 (Gentoo-based). Read on for the results.
Debian Burning DVDs on Debian for Newbies
Post date: December 22, 2005, 19:12 Category: Multimedia Views: 64
Tutorial quote: DVD writers have become so common these days that there is hardly any difference between the price of a CD-writer drive and a DVD-writer drive. So I'm assuming that almost everyone would be buying a DVD writer drive these days. Below are a few tips for newbies on how to burn DVDs on a Debian box using the command line. Other GUI tools like k3b, nautilus burner, etc exists but its always fun to know how to do that stuff from command line.
Debian Configuring Dynamic DNS & DHCP on Debian Stable
Post date: February 2, 2006, 20:02 Category: Network Views: 55
Tutorial quote: For the average home computer user there is no need to install a complex package such as the Internet Software Consortium's BIND DNS or DHCP server, since there are far simpler lower resource tools to use, for example dnsmasq. For those who you wish to learn how to use ISC's BIND and DHCP, for example as a learning exercise, this is how I got it all to work in Debian Sarge, the current stable version of Debian GNU/Linux.

This short article was prompted by my question on the Debian-Administration forum site, where I was able to get some answers to the issues I faced and I did promise to post a solution if I got one.
Fedora+Core Enhancing Apache with mod_security
Post date: April 12, 2005, 14:04 Category: Security Views: 93
Tutorial quote: Like probably quite a few of you, I run and admin some websites (some for fun, some for work), and as many of you surely do, some of these websites are mounted on a CMS. CMS are not the 8th wonder of the world, however some of them are pretty good, and they save you a lot of time by automating tons of tasks... however, as in every piece of code there exists, all of them are insecure and buggy (in fact, every piece of software is insecure and buggy to a degree)

So, searching for tools and ways to prevent people from breaking into my site without authorization, I began my search and found a great piece of software: mod_security for Apache.
