Soul of Information Information Technology

Archive for the ‘Linux’ Category

Linux is a very popular platform. Not just because it is free but also because it is reliable and supports anything you can imagine. A popular setup is a Linux server without any graphical user interface. It can be used for web hosting, as a file server, as a database server, or for anything you need. Most people comfortable with Windows operating system are afraid to start thinking in a different way. In fact, installing and using Linux is pretty simple.

Quite a few people have a tendency to dabble in Linux. This means that from time to time, they might download a distribution, burn it to a Live CD, and try it out on their computer without actually installing it to their machine. If you are a Windows user who is doing this, you need to try Linux on a dedicated computer.

Once you decide to go for it you have already made the first step. The next step is to get some basic information about installing Linux. There are many Linux distributions. One that is very popular is Ubuntu. Simply Google for “ubuntu server” and learn about what do you need to install Linux. In general, things are pretty simple. You can install Linux on almost any machine. Your old computer that was replaced some time ago is a perfect choice for Linux. You only need some space on the hard drive, a CD or DVD drive, a network card and a lot of patience.

The first step is to make a bootable CD with the latest Ubuntu server image. Download the image file and burn it on a CD. Then you boot your computer with this CD and start installing Linux. It is a good idea to do this installation next to your main computer with internet accesses. This way you will be able to browse for any problem you may encounter. The most important thing you should know is that for every question you may have, there is an answer on some web page waiting for you. You only have to find it.

The installation process is pretty straight-forward. If you don’t understand what the installer is asking you then simply select the default option. Of course, you can also ask Google for it and then choose appropriate option. You should understand that the Linux principle is very different from the Windows one. But once you become familiar with Linux shell and basic commands it will be very easy to work with Linux and to install and configure new software.

Having a Linux computer is a great upgrade to your home local area network. This server will be your reliable storage for large peer-to-peer files, web server for website development or a computer to play with. And remember, sooner or later you will encounter a problem. Something will not work or you will not know how to change some setting. All you have to do is to search for the answer on the web. Web pages offer a giant encyclopedia on Linux.

White Paper World – Free White Papers

White Paper World is a place for IT professionals to collaborate, obtain insight, share knowledge, and make intelligent purchasing decisions. Currently, there are several IT websites that are editorial based, and low in user generated content. While this is a great thing, White Paper World plans to create a more user centric platform, where peers can share information across a vast network of high ranking technology professionals. White Paper World will be a professional network, specializing in problem solving and enterprise software reviews.

In all, White Paper World will attract network administrators, database professionals, IT developers, managers, and executive, including CIOs and CTOs. We will attract a market that encompasses over 100 Million people around the world, and a market that has a true unlimited growth potential. With technology, there is no limit to growth, and thus, there is no limit on the technology market’s workforce. We will attract not only IT professionals from North America, but also European nations, the Middle East, and technology rich countries such as Japan and India. This is more than a $100 Billion market when you take B2B advertising into account.

While there are no direct competitors, there will certainly be several networks trying to obtain business from the same potential pool of buyers. We will separate ourselves by changing the way the industry works. Rather than editorial content, and reviews from the “big wigs,” we will offer user generated content and idea sharing, unmatched by anyone in the industry. Further, we will beat our competitors on price point, since we will have more advertising inventory to sell – it is proven that social media sites attract more visitors, and generate more page views per visit than comparable editorial networks.

Revenues will be generated from the sale of online advertising and marketing solutions. Initially, we will start with banners and text links, either charging on a CPM (cost per thousand impressions) or CPC (cost per click) basis. Next, we will incorporate B2B lead generation, email marketing blasts, and a monetized job posting service. With our audience and traffic numbers will come advertising revenue. Once a company sees the value of putting their message in front of our unique audience, it will be tough for them to pass it up. We will seek to sign vendors in the technology, software, hardware, and telecommunications industries. The targets will be top level marketing managers and executives.

The team will be made up of a 40-50 employee structure, starting with sales. Sales will sell the product to marketers, and then pass the torch onto client services, who will handle all client marketing interactions. Sales and Client Services will be the main contact point for the customers. Below this, we will have a community and website development team on the back end. We will also have people working accounts payable, accounts receivable, and taking care of the legal side of things.

The promise with White Paper World, is that we are going to make a significant amount of revenue, in a low cost service based industry. Once we get a steady audience visiting the network, advertising inventory will take care of itself – we will have all of the users and traffic that we need to sell interactive marketing units and lead generation programs. We will generate about $1 Million in projected revenue over the first year, followed by 50% growth in the next 2-5. This number is actually conservative, given the size of the target market, and the price point of our advertising solutions. With that, we ask for $4.75 Million in funding, which will be recuperated in revenue with 3 year’s time. Following the first 5 years in business, we will reach milestones of $10 Million in revenue by year 10, and $50 Million and beyond within the coming twenty years. This business model is proven, yet also innovative, as it something that has never been done before – we are taking social media, online advertising, and the b2b technology world to a new level.

Notebooks are used widely throughout the world with one in almost every household. No Contract Cell Phones devices oppose no threat to Notebooks instead they just make them more capable. What was made to basically surf the web or handheld data transfer or upload, is now the most advanced in technology history. The computer chip maker, Intel, is now trying to stake its claim in the 3G Cell Phones / smart phone industry. They are said to be making an open source operating system for mobile devices known as Moblin, hoping to branch out of its regular business confines of microprocessors. It is just one of many computer and internet based companies that is now trying to get in on the smart phone revolution.

Moblin, which stands for Mobile Linux, offers panel-based navigation to browse running programs, widget based social networking applications as well as a Firefox browser. Intel will allow programmers and developers write programs that will work on multiple platforms as well as different types of computers. This innovation does not compare with anything establishing a connection to a network, such as Aircards or USB Network Adapters. As popular as the Mac may be multitasking is taking a new role in modern tech society.

The idea behind the Intel company move is to break into the cellular industry because as 3G Cell Phones become more the standard for accessing the internet it becomes imperative that these once top of the line computer and software makers aren’t left in the dust of newer innovative companies. This marks a stretch in the industry in which software makers must make the leap, whether they like it or not, into the smart phone industry. Inevitably this is where the computing industry is heading. Completely, no. Laptops and desktops are as popular and as essential as ever but to think a company can sit back and watch others take control of the growing 3G cell phone / Smartphones industry is simply ludicrous.

This industry is a money maker and a place where companies can show off innovative creativity and become quite experimental. But those who do not get on board soon I fear will never get another opportunity to join in. It’s nice to see these companies finally testing the waters, and it’s great for us consumers, more competition between the companies and likely better products, too.

Yes, it the innovativeness and the competition between companies that should make consumers happiest. When more companies like Apple, Microsoft, Google and Intel get into the mix the more ideas are shared and the better products are produced. The technological geniuses that are now competing for our business, and the only way to get that business it make the best products available. So let the innovation take over while we simply choose which we like best. I guarantee by the end of this year we will see things on smart phones that we never thought possible. Remember that. Don’t say I didn’t tell you so.

Transferring Files from Windows to UNIX – White Papers

Unix FTP can be used to transfer files between PC’s and Unix-based file servers. File transfer protocol (FTP) is the network protocol that is used to transfer the files from the PC to the Unix file server over TCP. The Unix file server will need to have an FTP server installed, and the PC will need to have an FTP client installed. The standard port for FTP communication is port 21. IETF RFC 959 outlines the specifications for FTP.

Most FTP clients use an asynchronous method of communication, also referred to as non-blocking FTP. With this method, the FTP Client uses an asynchronous interface to the Windows sockets TCP/IP driver providing the fastest file transfer data rate possible while using a minimal amount of system resources.

Using FTP, Files can be uploaded and downloaded in either ASCII or binary format. Binary files are files where bytes in the file can be any 256 bit pattern. Examples of binary files include zip files, executables, images, and sound files. ASCII files are text-based binary files that can only use the 128 ASCII codes. Each ASCII character has a corresponding hex value and binary value. For example, the hex value for the letter “A” is 61, and the binary equivalent is 0110 0001.

The FTP server on the Unix server can be configured to require usernames and passwords, or to allow anonymous connections. With anonymous access configured, any and all users are able to upload files to and download files from all directories that are configured for public read and write permissions. On Unix servers, the File Manager can be used to set permissions on files and folders so that anonymous users cannot access them. Alternatively, user accounts can be created on the FTP server, assigned a username and password and access permissions applied at the user level.

Secure sockets layer (SSL) can be used for an added layer of security. With standard FTP, data that is transferred between the PC and the Unix server is not encrypted. Using FTP with SSL (FTPS) ensures that the data being transferred is protected from eavesdropping, tampering, or message forgery by encrypting the data before transferring it. IETF RFC 4217: “Securing FTP with TLS” outlines the specifications for FTP with SSL/TLS security. According to security standard for FTP, by default SSL encryption is only enabled on the command channel. This means that usernames, passwords and file locations are protected, but the transferred files remain vulnerable. To implicitly protect files that are uploaded and downloaded, the data channel also needs to be encrypted by enabling this configuration option in the FTP client.

Advanced FTP clients also provide additional productivity-enhancing features such as an intuitive GUI, the ability to save and transfer entire lists of files, and the ability to save a list of recently transferred files. A Windows GUI allows users to connect to the Unix server and manipulate the necessary files without having to become accustomed to the Unix interface. Many users transfer a specified list of files on a regular basis, or have the need to upload and download the same file multiple times. In this case, recent and custom file transfer lists can save users a lot of time.

With the popularity of Unix servers on the rise, Unix compatible FTP solutions are becoming increasingly commonplace and continue to expand their feature base. More about Windows, UNIX, and Linux: network protection

Dedicated Servers & Virtualization – Server Virtualization

Dedicated Servers: Whenever we talk about web hosting, there always comes a name “dedicated servers” that are the Rolls Royce of web hosting business. A powerful computer used solely as a network server is actually known as dedicated server. In other way we can say that where network needs, dedicated server is a single computer in a network reserved for. It lets you know the exclusive use of computer and its services are only valid for one domain name and account.

In a web hosting company’s premises a dedicated server is includes a web server, related software, internet connection and operating system. The purpose of all these is to develop a substantial amount of traffic for a particular website or a group of a company sites. The best thing is that we can customize the server according to our needs and it mostly operated and configured remotely from Clients Company. Server is owned by web host and no one can have the access of server physically. It can’t be used as a client.

Dedicated servers are adopted by a company when company wants more control on their servers. And if we talk about security then dedicated server providers utilize the extreme security measure to ensure the safety of data stored on their network of servers. A server provider provides you the software that you want to install on server. Generally dedicated servers are kept inside of data center so that they may be controlled by service provider.

The owners on internet business mostly prefer outsource dedicated servers because of the high technical nature of the requirement and the huge availability of networks from multiple providers. The providers of dedicated servers utilize huge amount of band width and obtain lower volume costs. Economically it’s not feasible for most of the hosting companies to develop a single network alone. Using dedicated servers over a typical shared hosting account gives advantage of increasing amount of resources and control available.

Yet no one has cleared the management role of dedicated server providers. Some providers define fully managed as having a web panel control, while other define it as a control over network related functions. So first management role of dedicated server should be cleared that help every internet business owners to utilize the whole services given by dedicated server providers.

There are lots of companies that are experts at managed dedicated server hosting. The services provides by these providers are dedicated boxes, RAID arrays, scalable bandwidth with back up and disaster recovery solutions. Most important thing is that control panels should not be confused with a full server management solution.

There are lots more about dedicated server and the management level of server. We’ll let you know soon…..
