The Importance of Domain Names Servers

Whenever you spend time on the Internet whether you are browsing or sending an email you are making use of a domain name server without even being consciously aware of it. Even though the work done by a domain name server is hidden it is extremely important as without domain name servers the Internet would shut down very rapidly.

A domain name server acts as a phone book for the Internet by translating computer host names such as www.example.com into an IP address. Translating domain names into IP addresses sounds like a simple task but due to the fact there are billions of IP addresses currently in use and most computers have a human readable name as well as the fact there are a billions of DNS requests made every day, for example a single person can easily make a hundred or more DNS requests a day and domain names and IP addresses change daily as well as the fact millions of new domain names get created daily, this simple task can turn a lot more complicated than first anticipated. A domain name server is also a database but it is a database that is unlike any other as it gets many requests and has millions of people changing it everyday, which is what makes it unique.

Each domain name consists of two parts - the Mid Level Domain (MLD), and the Top Level Domain (TLD). The Mid Level Domain is the Ford in Ford.com, the Concrete-Home in Concrete-Home.com. This part of the domain name can consist of up to 63 characters in .com, .net, or .org domains. Only letters, numbers, or hyphens are permitted; no underbars, exclamation marks or periods. The Top Level Domain refers to the .com, .net, or .org part of the web address. It is the mid level domain name that these domain name servers work on and change into an IP address in order for your web site address request to be noted and found.

As well as being able to direct you to the website that you wish to visit, a domain name server, known in short as DNS also stores other information such as a list of mail servers that accept email for a given domain. By providing a worldwide keyword-based redirection service, the Domain Name System is an essential component of contemporary Internet use.

The Domain Name Server distributes the responsibility for assigning domain names and mapping them to IP networks by allowing an authoritative name server for each domain to keep track of its own changes, avoiding the need for a central register to be continually consulted and updated. Above all, the DNS makes it possible to assign domain names to organizations independent of the physical routing hierarchy represented by the numerical IP address. Because of this, hyperlinks and Internet contact information can remain the same, whatever the current IP routing arrangements may be, and can take a human-readable form (such as “example.com”).

Domain name servers make it possible for us to use the Internet for browsing purposes, purchasing purposes and sending emails. Whatever you use the Internet for you will be using the help of a domain name server.

Joomla a Great CMS

Joomla strives for power in simplicity. Its programmers believe that anyone with a bit of technical know-how should have no problem setting up and maintaining a website. They have created a tool that is friendly, comparatively easy to get started with, and prioritizes ease of use.

Joomla is designed to work just fine in basic shared hosting environments (the least expensive, most common web hosting package). Its installer looks much like the simple installers used for common desktop software, and the administrative interface that content editors use looks much like a desktop program as well. There are few barriers to entry with Joomla, which means it should not take a web developer much time to get you up and running, and if you’re technically savvy you may be able to do it yourself.

If you need to extend Joomla in a way not covered by its extensions—which happen to be beautifully documented and easy to find at extensions.joomla.org—you should not have to pay too much for a programmer, because Joomla is written in PHP, a widely-used general-purpose scripting language that is especially suited for Web development.

As is usually true, this ease of getting started comes with a tradeoff. Joomla can be a great choice to build a sophisticated website with hundreds of pages, solid navigation, and common content types such as news items or events. However, it has limited out-of- the box functionality for dealing with sophisticated dynamic content structures. For instance, the site navigation is limited to no more than two levels of hierarchy, and you can only link one page to another (for a “you might also be interested in” type of structure) based on free-form page tags, rather than more rigorous metadata and rules.

The next major release of Joomla, version 1.5, should be out by year-end. This version will be a rewrite of the underlying code, in order to make it easier for programmers to extend certain functionality and organize underlying frameworks, but it is not expected to change the way that content editors interact with Joomla. Site visitors should have no idea that anything has changed.

Joomla is fully integrated with CiviCRM and integrates well with common packages like DemocracyInAction and GetActive.

Create a VPN In Minutes…

Maybe you need to connect your network to terminals in different locations securely using the internet. Well a great tool, an Open Source tool lets you do that in a secure and safe manner.webgui-screenshot

OpenVPN is the best software to accomplish that. This software used for little, medium and large companies is recognized as the “Best SSL VPN” in 2007 and “Best Open Software Award”.

I had to create a network between 3 offices; Cancun, Mexico City and San Luis Potosi and it took me 15 minutes to do it with this tool.

A virtual private network (VPN) is a computer network in which some of the links between nodes are carried by open connections or virtual circuits in some larger network (e.g., the Internet) instead of by physical wires.

About OpenVPN

OpenVPN is a full-featured open source SSL VPN solution that accommodates a wide range of configurations, including remote access, site-to-site VPNs, Wi-Fi security, and enterprise-scale remote access solutions with load balancing, failover, and fine-grained access-controls. Starting with the fundamental premise that complexity is the enemy of security, OpenVPN offers a cost-effective, lightweight alternative to other VPN technologies that is well-targeted for the SME and enterprise markets.

OpenVPN combines security with ease-of-use

OpenVPN’s lightweight design sheds many of the complexities that characterize other VPN implementations. The OpenVPN security model is based on SSL, the industry standard for secure communications via the internet. OpenVPN implements OSI layer 2 or 3 secure network extension using the SSL/TLS protocol, supports flexible client authentication methods based on certificates, smart cards, and/or 2-factor authentication, and allows user or group-specific access control policies using firewall rules applied to the VPN virtual interface. OpenVPN is not a web application proxy and does not operate through a web browser.

Best of all is that you can use this software on Windows, Linux and Mac OS. So if you want to download it go to main site of OpenVPM or download GUI for  Windows, Linux and Mac OS.
