Post date: June 6, 2006, 19:06 Category: Software Views: 3539 Comments
Tutorial quote: This is very detailed tutorial for implemeting bacula network backup in debian linux.This tutorial contails totally 4 pages.

Bacula is a set of computer programs that permits you (or the system administrator) to manage backup, recovery, and verification of computer data across a network of computers of different kinds. Bacula can also run entirely upon a single computer, and can backup to various types of media, including tape and disk.

In technical terms, it is a network Client/Server based backup program. Bacula is relatively easy to use and efficient, while offering many advanced storage management features that make it easy to find and recover lost or damaged files. Due to its modular design, Bacula is scalable from small single computer systems to systems consisting of hundreds of computers located over a large network.

Screen: an introduction and beginner's tutorial

Post date: April 15, 2005, 23:04 Category: Software Views: 2512 Comments
Tutorial quote: Most modern Unix-based operating systems (e.g. Linux, MacOS X, and BSD) come with a little console-mode utility called GNU Screen. It's a powerful tool in the hands of the console warrior, a veritable Swiss Army knife of text-mode human-computer interaction.

This utility, despite its considerable usefulness, goes unused by a great many people. Why is this? Few people even know it's there, and those that do rarely understand the problem it solves. In this article, I will explain what screen does for you, and provide a simple set of instructions for accomplishing basic tasks using screen. My audience is those that are skilled with the command line but who have little or no experience with screen itself.

Making Web Browsing Easy For The Tiny Screen

Post date: August 9, 2005, 19:08 Category: Network Views: 2753 Comments
Tutorial quote: An avalanche of content will soon appear in the palm of your hand.

Tiny screens are showing up everywhere in PDAs and cell phones. Many are equipped with some form of network device and a browser, so it's not hard to see what's coming down the pike.

Late model PDAs, like my HP iPAQ 3715 no longer suffer from insufficient computing power, lack of memory or having to rely on pricey external 802.11b cards. The little machine is quick to boot up and can handle many daily business functions.

Even though it runs a version of Internet Explorer, jumping onto an access point and browsing web pages is fast and useful.

In this edition, I'll share my observations on things you might consider when converting LAMP (Linux, Apache, MySQL, PHP) applications or web pages, for use on the tiny screen. I'll approach the issues from an iPAQ user perspective and focus on convenience and making the user's life easy.

The PartImage Handbook

Post date: May 21, 2005, 15:05 Category: Software Views: 2505 Comments
Tutorial quote: - Partition Image is a Linux/UNIX partition imaging utility: it saves partitions formatted using the Ext2FS (the linux standard), ReiserFS (a new journaled and powerful file system), JFS IBM journaled file systems from AIX, NTFS (Windows NT File System), FAT16/32 (DOS & Windows file systems), or HPFS (OS/2 file system) file system formats to an image file. Only used blocks are copied. The image file can be compressed in the GZIP/BZIP2 formats to save disk space, and split into multiple files to be copied on removable media (ZIP for example), or burned on a CD-R ...

- This allows the user to save a full Linux/Windows system, with a single operation. When problems occur (viruses, crash, error, ...), you just have to restore, and after several minutes, all your system is restored (boot, files, ...), and fully working.

- This is very useful when installing the same software on many machines: just install one of them, create an image, and then restore the image on all other machines. After the first one, each subsequent installation can be made automaticaly, and only requires a few minutes.

Setting up an Ubuntu media server

Post date: April 23, 2008, 12:04 Category: Installing Views: 14672 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.

Tutorial quote: Sendmail has the reputation of having the most hideous configuration file in the history of mankind. It's extremely long and incredibly cryptic. However, it is this very complexity that has made it the most popular MTA (Mail Transport Agent) on the Internet. Its' flexibility allows sendmail to handle the most demanding, disjointed mail routing and serving configurations you can dream up.

Installing Ubuntu From A Windows System With Wubi

Post date: September 11, 2007, 22:09 Category: Installing Views: 3195 Comments
Tutorial quote: Wubi is an Ubuntu installer for Windows that lets you install and uninstall Ubuntu from a Windows desktop. Wubi adds an entry to the Windows boot menu which allows you to run Linux. Ubuntu is installed within a file in the Windows file system (a loopmounted partition), this file is seen by Ubuntu as a real hard disk. That way the hard drive does not have to be repartitioned before the Ubuntu installation. The resulting Ubuntu installation is a "real" Linux system, not just a virtual machine. Wubi makes it easy for Linux newbies to play around with Ubuntu.
