In this tutorial I’ll show you how to use a remote (over the internet) based computer’s file system like a local one.
You will be able to use it exactly like you use a normal folder cutting, copying, pasting and creating documents etc.

KDE is one of the most popular and used desktop environments for Linux systems because not only that it looks very much like Microsoft Windows, but it combines ease of use, superb graphical design and new age functionality with high-end technologies of the Unix-based operating systems. Kicker is one of the core parts of the KDE desktop, it is the main panel. This panel can be customized by users in almost every possible way you think of. For example, you can add a lot of useful applets (clock, system tray, show desktop, color picker, desktop preview & pager, dictionary and many more), application shortcuts or you can make it completely transparent
Kicker also has a lot of configuration options that are not revealed in any of the existing graphical user interfaces but can be very useful for advanced users. You must know first that these options are found in the /usr/share/config.kcfg/kickerSettings.kcfg and the /home/yourusername/.kde/share/config/kickerrc configuration files. Below are some of the top tweaks found in the kickerSettings.kcfg file, but nothing stops you to read and modify, as necessary, every option.
Alot of people are freaked out by IPTables and find it hard to understand. However, once you get the grasp of it the basics are easy. This document will serve as a basic how-to on using iptables.

Youtube-dl is a python based platform independent command line tool to download any videos from youtube. In ubuntu, it’s already in the repo just download it using apt-get; others can download it from the authors website http://www.arrakis.es/~rggi3/youtube-dl/.
The instructions is pretty straight forward. In the terminal type, youtube-dl “youtube_video_address” this will save the video in flv format with can be viewed with most popular video player like VLC or Mplayer for linux. If you want to save video file to something else you could use the -o option like this: youtube-dl -o video.flv “youtube_video_address”.
This tool is a life saver . I had to use it today to debug some mail issues , a client chould not log in . If you know how to use it you will know everything is happening on your network – in and out
Anyway i whould like to say thanks to the makers ngrep.sourceforge.net
Chances are if you have the know how to use Gentoo and made it thus far to get it installed you probably don’t need this tutorial, but it’s good to have as much documentation as possible. Emerge makes installing easy, just as apt-get would be Ubuntu, but in emerge we can install source built applications rather than binary applications, thus is the Gentoo way. And along with that is many more options for these packages. This tutorial will just cover the basics.
Emerge searches through the Portage Tree for applications. The Portage tree is a collection of ebuilds files that contain all information Portage needs to maintain software (install, search, query, …). These ebuilds reside in /usr/portage by default.
Whenever you ask Portage to perform some action regarding software titles, it will use the ebuilds on your system as a base. It is therefore important that you regularly update the ebuilds on your system so Portage knows about new software, security updates, etc.
Many people get confused when trying to boot in to a runlevel other than runlevel 5, for example runlevel 3, disabiling the GUI front end with which most users are familiar. Hopefully this howto will help answer the questions “How do I disable X” or “How do I boot without X” or even “How do I get to single user mode.”
One requirement of this is to have an understanding of what runlevels are, how changing runlevels will impact your system, and what services may or may not be started. In general this is beyond the scope of this document but I will give a quick run down of things as listed in /etc/inittab.
Just a warning, this does not apply to Ubuntu as Ubuntu focuses on Upstart.
You might have noticed there is an entry in your KDE and Gnome menu called “Start New Session” ( In some distros “Switch User” ). I will try to explain a few things about this feature.
You can, at any time, do Ctrl+Alt+F1 ( to F6 ) to get a text console you could log in as another user ( also as root ) to perform needed tasks and at the same time have your X running under Ctrl+Alt+F7. So switching up and down between the X session and the text session was easy as pressing a few keys on your keyboard.
You more than likely already have alsamixer installed on your computer, even if you just don’t know it’s there. Simply type “alsamixer” on the command line and you will be presented with:
It does everything most graphical volume controls do and does it just as good. It handles setting the volume, controlling 3D switches, CD audio volume and line-in ports just like the graphical versions you are normally accustomed to. Key controls are a simple combination of left and right arrow keys, up and down keys and the M button to mute a channel. Simple, right?
The great part of alsamixer is that you don’t have to mess with the amixer terminal commands to set the volume on your rig. And it runs on a fraction of the space, with no need for a particular desktop environment to work. It’s a natural born utility
