TrueCrypt - Free opensource on the fly Disk Encryption tool

Post date: August 7, 2008, 22:08 Category: Security Views: 4182 Comments
Tutorial quote: TrueCrypt is a free opensource software system for establishing and maintaining an on-the-fly-encrypted volume (data storage device). On-the-fly encryption means that data are automatically encrypted or decrypted right before they are loaded or saved, without any user intervention. No data stored on an encrypted volume can be read (decrypted) without using the correct password/keyfile(s) or correct encryption keys. Entire file system is encrypted (e.g., file names, folder names, contents of every file, free space, meta data, etc).

How To Look Like A UNIX Guru

Post date: October 30, 2006, 02:10 Category: Miscellaneous Views: 6492 Comments
Tutorial quote: UNIX is an extremely popular platform for deploying server software partly because of its security and stability, but also because it has a rich set of command line and scripting tools. Programmers use these tools for manipulating the file system, processing log files, and generally automating as much as possible.

If you want to be a serious server developer, you will need to have a certain facility with a number of UNIX tools; about 15. You will start to see similarities among them, particularly regular expressions, and soon you will feel very comfortable. Combining the simple commands, you can build very powerful tools very quickly--much faster than you could build the equivalent functionality in C or Java, for example.

This lecture takes you through the basic commands and then shows you how to combine them in simple patterns or idioms to provide sophisticated functionality like histogramming. This lecture assumes you know what a shell is and that you have some basic familiarity with UNIX.

Xen Virtualization and Linux Clustering, Part 1

Post date: January 21, 2006, 06:01 Category: System Views: 4498 Comments
Tutorial quote: Have you heard about Xen virtualization and want to get some hands-on experience? Do you want to experiment with Linux clustering but only have a single computer to devote to the cause? If you answered yes to either of these questions, keep reading.

In this article, I briefly introduce the concepts of Xen virtualization and Linux clustering. From there, I show you how to set up multiple operating systems on a single computer using Xen and how to configure them for use with clustering. I should point out that a cluster implemented in this manner does not provide the computational power of multiple physical computers. It does, however, offer a way to prototype a cluster as well as provide a cost-effective development environment for cluster-based software. Even if you're not interested in clustering, this article gives you hands-on experience using Xen virtualization.

Protect Your Files With TrueCrypt 5.1a On Debian Etch (GNOME)

Streaming music with SlimServer

Post date: June 15, 2005, 16:06 Category: Network Views: 4201 Comments
Tutorial quote: Converting your CD collection into MP3 or another digital file format gives you the ability to enjoy the music on your computer and stream it all over the house and the Internet. To do the latter, however, you have to install and configure a streaming server on your computer. That might sound like a daunting task, but there is a streaming server application that makes the whole process pretty painless. SlimServer from Slim Devices is a cross-platform streaming server that runs on Windows, Linux, and Mac OS X and supports a wide range of formats, including AAC, AIFF, FLAC, Ogg Vorbis, MP3, WAV, and WMA. Although it was developed to stream music files to Slim Devices' Squeezebox2 hardware player, it works perfectly with any software MP3 player capable of working with network streams.

Boot Debian from an external firewire drive on PowerPc Mac

Post date: December 14, 2005, 19:12 Category: Installing Views: 3193 Comments
Tutorial quote: Messing with a boot process is a delicate matter even on a Mac. Note that the Debian installer will fail at some point during the procedure.
I offer no warranty and assume no responsibility for whatever loss or damage might be caused to your hardware, software or data.
There are other ways to boot Linux from an external firewire drive documented elsewhere on the net. See the Resources section.

Adding or removing peripherals like usb keys, digital cameras, other external HDs, cdroms etc, or installing/removing devfs, udev, and similar stuff might alter the way Linux sees the firewire drive, i suggest becoming familiar with supplying boot options to yaboot during the boot process. See Man pages of yaboot and yaboot.conf.

Installing and securing Squid

Post date: March 13, 2006, 15:03 Category: Software Views: 5689 Comments
Tutorial quote: Squid is a high-performance proxy caching server for web clients, supporting FTP, gopher, and HTTP data objects. Unlike traditional caching software, Squid handles all requests in a single, non-blocking, I/O-driven process. Squid keeps meta data and especially hot objects cached in RAM, caches DNS lookups, supports non-blocking DNS lookups, and implements negative caching of failed requests. Squid supports SSL, extensive access controls, and full request logging. By using the lightweight Internet Cache Protocol, Squid caches can be arranged in a hierarchy or mesh for additional bandwidth savings.

After the installation and base configuration of squid we will add another layer of security by chrooting it.

Creating DjVu Documents Linux HOWTO

Post date: July 16, 2006, 16:07 Category: Miscellaneous Views: 4678 Comments
Tutorial quote: This document explains some of the uses of djvulibre implementation of DjVu for creating quality DjVu documents in linux. DjVu format features bitmap document compression and hypertext structure. It is used by numerous web sites all around the world for storing and distributing digital documents including scanned documents and high-resolution pictures. One of the advantages of DjVu files is that they are notably small, often smaller than PDF or JPEG files with the same content. This makes DjVu a helpful tool for digitizing books and journals, especially scientific ones.

Below it is considered the case when a DjVu document is created from a number of separate JPEG files each containing a single page. Here JPEG format is not a limitation, and the examples can cover arbitrary image formats. Conversion from PDF to DjVu is also discussed. Usage of scanner software is not explained: refer to the relevant documentation.

Setting up an Ubuntu media server

Post date: April 23, 2008, 12:04 Category: Installing Views: 15423 Comments
Tutorial quote: In today's tip I'm going to run through how to setup an Ubuntu media server. First of all, what is Ubuntu. Wikipedia says:

Ubuntu is a Linux distribution for desktops, laptops, and servers. It has consistently been rated among the most popular of the many GNU/Linux distributions. Ubuntu's goals include providing an up-to-date yet stable operating system for the average user and having a strong focus on usability and ease of installation.

It is very much like apache, which I showed you how to setup in my article on how to make your computer into a local server, in that it is commonly used as a server software. Now then, what is a media server?

To refer to Wikipedia again, a media server is

A media server is a computer appliance, ranging from an enterprise class machine providing video on demand, to, more commonly, a small home computer storing various digital media.

Basically, it's just like a local server which stores and shares solely media instead of other types of files. I'll leave the uses of one to your imagination. Let's on with setting it up.

Building a Linux video jukebox for an anime convention

Post date: November 25, 2005, 21:11 Category: Miscellaneous Views: 3768 Comments
Tutorial quote: I wrote this little whitepaper a while back for Amy Zunk to document the function of the VideoKeg/VideoJukebox boxes. Documented here for posterity. The primary goal of the video keg was to build a reliable video box that was easy to transport with enough space to store 3 days worth of Anime fan-subs.

The secondary goal of the video keg was to make a home PVR system for video playback and time-shifting, along with a video arcade and perhaps a web browser. The tertiary goal of the video keg was to find an affordable hardware platform so that we could buy 4 of them immmediately to service the primary goal's need for 4 separate video rooms.

For a PVR, the machine neeed to be small, quiet, low-heat, and still fast enough to run the software video player and arcade games. For portability, we decided to go with a smaller mini-ITX style cube box.
