Solution to the DSL-500T Router problem

The only DLink ADSL router in the market, as of January 2005, in Cairo is the model DSL-500T. It is sold at around 340 EGP from a DLink distributer at a new computer mall in Heliopolis named Souq El 3asr (brands).

Before buying this model, I heard that there might be some issues with ssh connections. However, I knew that T models of DLink routers run GNU/Linux, so I didn't bother since Linux is an open platform, we are familiar with, we can hack and troubleshoot up to compiling a new kernel.

Video encoding for dummies

Hmm ok, so if you've read anything I wrote before you, then should already know that writing isn't my thing..

Yep and grammar isn't my thing either

Before we start you need :

• xvid for linux (emerge xvid or find a package for your distro).
• lame/libmp3lame (emerge lame or find a package for your distro).
• vorbis-tools (only for using ogg sound).
• mkvtoolnix/libmatroska (only for using the matroska container and ogg sound)
• mplayer/mencoder (USE="encode xvid matroska oggvorbis" emerge mplayer or find a package for your distro).
• the ability to read and understand bad grammar.
• some common sense (search for it in your favorite S-Mart).

Using The AutoTools

If you think one day to start programming on linux, sure you will use C language (not me, i will always use assembly), but when your program sources get biggers as its version increase or you want to publish its source code, how users gonna to use it, are they gonna to compile every source file separetely then link them all together, no it's a bad idea and very handy, you will have to use the autoscripts.

In this article i will describe how to use the autoscripts for your own program sources, so i will write a simple C sourcefile to show you how to use the autoscripts(autoheader,automake,autoconf).

What is IRC?

IRC is a text based chatting protocol. You as a user chat through what is called IRC client. The client is a program installed on your system and connects to an IRC network. A network is a group of servers connected to each other to manage the exchange of messages. Users connected to the same network can chat together even if each is connected to a different server as long as these servers belong to the same network. Each network has a group of what is called chat rooms or channels reaching to thousands of channels. If one join a room he'll be able to chat with all those who joined the same room in a conference fashion. As

LINUX FIREWALLS

IPATBLES

by ramez.hanna

This is not a reference to IPTABLES in any way it is just a start that i gathered from several other documents with my humble knowledge and experience and i hope it could get you started with the firewalls configuration. This document is far from complete and I'll be adding more as soon as i have the time

General

Before we mention anything about firewalls i need to point out a critical point “a firewall’s power lies within the configuration” meaning that no matter what the firewall application power is, a weak configuration will weaken it.And also remember that security is not just a firewall. Think of a firewall as just a first line of defense you need to secure your applications and keep your system updated and patched for any exploits to secure your applications Mainly a firewall is used to block or allow certain traffic based upon the network needs, it may block all incoming requests or it may allow requests to go through to the mail server within the local network The firewall in Linux sits in the kernel waiting for network traffic from the NICs and handles it as mentioned in the configuration file.

The vi editor is certainly not the easiest and most user-friendly text editor, but because of its wide availability and existence on most linux systems

The vi editor operates in two basic modes:

1. Command mode
2. Insert mode

when vi is started, it is in command mode. This mode allows you to enter commands to edit files or navigate your text file. However, you can only add or insert text by using the insert mode. from command mode, you can enter insert mode by typing the letter i. To return to command mode, use the Escape key
