The Benefits of Multiple Domain Web Hosting

Thanks to the low charge of domain names and hosting fees it is conceivable to own many websites without breaking the bank. There are a few ways to handle multiple domains so it is vital to understand what your options are and the benefits and disadvantages of each approach. The most elementary selection when managing multiple domains is whether to do so with the identical hosting company. Most hosts offer packages which can allow several sites to be attached to one account, or allow single sites to run under separate accounts. You may own an existing website and be delighted with the services your host provides. If you resolve to start a new website using the identical host, dealing with a company you are familiar with and trust will comfort you.

You may also get a discount for each added account you open with the same host. On the other hand, using a new host for a second (or third or fourth) website can allow you to compare the quality of hosting offered by different companies. In addition, separate hosts will provide each of your web sites with a different IP address.

Having different IP addresses can be critical if you intend to link the sites together to aid in search engine optimization. Incoming links are an important pointer of how consequential a website is, so a site with many incoming links can get a higher position in search engines like Google . If all the links are coming from the same IP address, however, Google may reduce their value. Hosting your numerous sites with different hosting companies guarantees that each site has a different IP address. Individual IP addresses, however, are available at an extra cost from most web hosts. For a yearly fee each website can have its own unique IP address. This can help with search engine ranking and if you want to have a secure connection (https) on your site.

If you decide to host all your sites with the same company, there are three basic ways to go. Each site could have its own account; you could sign up for a reseller account; or you could get a dedicated server account. As a reseller you are acting as an agent for the hosting company. They apportion some disk space and bandwidth to you which you use as you please. There may be a limitation to the number of websites you can host with your reseller account. If you have space left after using this account for your own sites you could earn some extra income by selling accounts to other people. The advantage of a reseller account is the hosting company taking care of all the technical details. Some will even provide gateways for billing your customers.

A dedicated server account gives you command of all the resources of an entire server. You are free to setup as many websites as you wish and assign disk space and bandwidth as you see fit. The disadvantage to this account is that you are responsible for maintaining the server. This requires significant technical know-how so if you don't have that knowledge or don't feel like learning about it, dedicated servers are not for you. You can, of course, go with a managed dedicated server. The disadvantage of this is the higher cost involved.

Hosting all your sites with one host can offer many advantages but there is one chief drawback : if your server goes down, all your sites go down. If you are depending on your sites for income this can be catastrophic. So, it is a good idea to have at least one of your sites with a different host. If your sites are essential for your livelihood and you can't manage any down time whatever, it is better to host everything with (at least) two hosts

What's soooooo important inside that network?

Unauthorized access is age old. It began with the Romans and their poor, landless citizens attempting to infiltrate colossal Roman castles. The concept within Internet hacking is relatively similar, all based around a single theme: information. Those with information, therefore, have access and power, even if it is confined to one particular network, for a short amount of time. The importance, then, of hacking, can be said to include information and power. Gravy... This begs the question of how these hackers gain access to networks. Some common tricks include password deciphering, buffer overflows, scripts and DoS attacks. The purpose of this article is to introduce you to what exactly hackers do to gain access, and to quench the steadfast intrigue of these concepts.

What are hackers? What are crackers?

Definitions for these two terms vary, but suffice it to say that hackers are those exceptionally knowledgeable computer users, often skilled in programming languages and Internet logic. The term hacker, then, can conceivably be used with either a positive or negative connotation. Throughout the years, this term has gained much momentum to the negative. Now, the term often means to gain access to a network, after hacking their way in. The term crack means to break into a computer system. Hackers wish to differentiate the two terms, as hackers are said to strive towards information for the purposes of pranks, or web site 'modification'. Crackers, on the other hand, have a specific purpose to break into secure systems, capture the password(s) and wreak havoc on the machine. Since these two terms are often used reciprocally, this article will exercise the terms hacker and hack, opposed to cracker and crack.

Efforts to gain passwords

SIMPLE INVESTIGATION

Let's get into the meat and potatoes of what hacking is all about: capturing the often illusive password. By their nature, passwords should be illusive, but hackers contrive methods and techniques to gather them, and use them for their own purposes within a network. The password is the lowest, but ultimately the most important, step in the hacking totem pole. Once a password is compromised (or seized), hackers use it to realize additional rights and privileges within the system.

So, how are passwords seized? Regardless of how secure the network itself is, there are always insecurities, and that includes the actual users of the network (or, Mr. Do Mas). Sure, hackers can use sophisticated password utilities to guess passwords on a system, but oftentimes a little investigation provides what the hacker is looking for. Believe it or not, a major source of password compromise is the simple laziness of users. Users write the passwords down on little Post-It notes and place them within their desk. Users give their passwords to others. Passwords are printed out on pieces of paper that are often thrown out whole. A little rummaging through an office and its waste can surface more information than you might imagine.

Hackers also use a technique known as social engineering. They may call up a network administrator, pose as a confused network user and claim that they lost his or her password. This works way too often and many times is the first thing that hackers try.

TROJAN HORSES

The war between the Achaeans and the Trojans continued for 10 long years. After the death of Achilles (known as the greatest warrior among the Greeks), the Achaeans constructed a wooden horse and filled it with warriors and brought it into the city of Troy. Once inside, the warriors exploded from the wooden horse and destroyed the city; or so the legend goes. A trojan horse in computer terms means essentially the same thing, a seemingly harmless computer program infiltrates the computer system, while malicious routines are being executed behind the scenes. One of the first trojan horses was a program that impersonated a login box. Once the user enters his or her password, they are saved in a location that the hacker has access to.

This type of trojan horse is commonly installed on library computers, or an otherwise public computing environment. Trojan horses are often more disguised than a simple login prompt. Windows and Linux system commands, for example, are susceptible to manipulation. Without getting into technicalities, the windows command edit can be compromised and instructed to launch a malignant batch file behind the scenes, deleting or even adding user accounts with administrator privileges. Remember that a trojan horse is an executable file, which can be recognized with the .exe, .vbs, .com, etc extensions. A trojan horse sent through e-mail can often be found by noticing an extension like .txt.vbs.

PACKET SNIFFERS

Network data travels through network media in variable sized packets. These packets, of course, are never seen in their raw form, as a series of network protocol rules convert such packets to data that applications can interpret and display. However, before data packet arrives at the recipient's computer, the packet can be snatched out of the media by packet sniffing software. Because such utilities, like Telnet or SNMP, were designed to send passwords over network media in plaintext, or unencrypted form, passwords can be easily compromised using this method.

Note that packet sniffers are capturing utilities, and cannot be used to actually modify any of the seized data packets. Sniffers can capture data within multiple protocols, like IP (Internet Protocol), UDP (User Datagram Protocol) and TCP (Transmission Control Protocol), allowing a single application to function well within a wide array of computing environments. Passwords are not the only way hackers gain access to networks. Next, we will take a look at buffer overflows, and what it provides to hackers

3 Important factors you must consider before choosing your web hosting provider!

If you are planning to transfere your business online, or even will start your business on the internet from scratch, the first thing you will face is: where you will host your websites? and if you are new to this area (web hosting), you will find yourself a bit confused about many webhosting terminology, so it'll be very important to you to understand these terms before you take your decision. Here, I will mention to the most important factors you must take in consideration:

1. Bandwidth: (data transfer) is measured in gigabytes. A gigabyte is one billion bytes. Each letter is one byte. Images can take up a big amount of kilobytes (thousands of bytes), and file downloads can be several megabytes (millions of bytes) in size. You must logically think of how much bandwidth your website will need. Unless your website has a lot of downloads, it will be unlikely that you will need many gigabytes of transfer - 10 gigabytes should be very enough. Any more, and you will just be paying extra for something to use. On that note though, you should be careful and make sure you always have some extra bandwidth - many hosting providers charge $3.00 and more for every extra gigabyte of bandwidth you use. That can add up very quickly.

2. # Of hosted domains allowed: One of the most important factors which must be taken into account when choosing your hosting provider is the number of websites that allow you to host on a single account, some hosting companies allow only for one domain per account, some other companies will allow you to host an unlimited websites per one account, meanning several aebsites at the expense of one. If you are serious about your business on the Internet then you must be aware of the fact that you will sooner or later will need to launch more websites to expand your business to high levels. Therefore it is important to take this point into consideration where you will remove the burden of purchasing additional webhosting accounts to host the new websites in the future.

3. Control Panel: Before you buy a web hosting plan, ask the hosting company show you a demo for the control panel from which you will administrate your hosting account. Control panel is the place where you can check your website visitor statistics, add or erase email accounts, host additional domains on your account, install scripts and make other nominal changes for your website. Control panel should be easy to use with friendly interface and you should take some time to understand what it is all about before purchasing your hosting plan
