Overall goal is that the gifts will be made to the participants on Friday May 31, 2013 and then in the ensuing four weeks the servers will be built and given to charity. Challenge participants will have 7 days to make their purchases and up to two additional days to document what they purchased. Since we are doing this on a budget, users will have up to 14 days to get their systems working and an additional two days to document what they did.

The term Web Server can refer to either the hardware (a computer) or the software (an application) that serves content accessed through the Internet. We receive a lot of email requests seeking recommendations on which hardware is supported and best suited for projects like this. Before getting started, please note that this build does have it's limitations and is intended for home or small office use on a Broadband connection. The Intel D525MW is an energy-efficient Mini-ITX Motherboard, built with the Intel NM10 Express Chipset, featuring an integrated Dual-core 1.8 GHz Intel Atom processor D525 and Intel Graphics Media Accelerator 3150 graphics core. This desktop board gives off very little heat and utilizes passive cooling which means there are no spinning fans generating nose when powered on. One thing I love about OCZ SSD products is that they include a 3.5-inch desktop adapter bracket with their drives.
Crucial's 4GB DDR3 memory kit for the Intel D525MW Motherboard is the perfect fit for our build. As with all Crucial products, these SODIMM modules come with free shipping, a life time warranty and of course made by one of the best memory manufactures in the business. A primary reason for me choosing this chassis was due in part to the included 65-Watt external AC to DC power supply adapter. As mentioned previously, this build is intended for home or small office use with low to moderate levels of web traffic.
I intentionally excluded a keyboard, mouse and optical drive from our hardware list because it lowers the build cost and shouldn't be required after initial installation. Shipping containers and software containers share a lot in common, but the analogy has limits.

With the recent explosion of WebSocket server implementations, a lot of questions have come up about how HTML5 Web Sockets deal with proxy servers, firewalls, and load-balancing routers. Let's start with some basic concepts: what exactly are HTML5 Web Sockets and proxy servers? The HTML5 Web Sockets specification defines the Web Sockets API that enables web pages to use the Web Socket protocol for full-duplex communication with a remote host.
To use HTML5 Web Sockets to connect from a Web client to a remote end-point, you create a new WebSocket instance and provide it with the URL that represents the end-point to which you want to connect.
A proxy server is a server that acts as an intermediary between a client and another server (for example, a web server on the Internet). The Web Socket protocol itself is unaware of proxy servers and firewalls; it just defines WebSocket upgrade handshake and the format for the WebSocket data frames.
If a browser is configured to use an explicit proxy server then it will first issue the HTTP CONNECT method to that proxy server while establishing the WebSocket connection. When the explicit proxy server allows the CONNECT method, the WebSocket connection upgrade handshake can be made and when that handshake succeeds, WebSocket traffic can start flowing unimpeded through the proxy server. In case the unencrypted WebSocket traffic flows through a transparent proxy on its way to the WebSocket server, the connection is likely to fail in practice, since the browser does not issue the CONNECT method in this case. During the WebSocket handshake, the Connection: Upgrade header is sent to the WebSocket server.
Today, most transparent proxy servers will not yet be familiar with the Web Socket protocol and these proxy servers will be unable to support the Web Socket protocol. Now, let’s take a look at encrypted WebSocket traffic in two proxy server scenarios (explicit and transparent).
If a browser is configured to use an explicit proxy server then it will first issue an HTTP CONNECT method to that proxy server while establishing the WebSocket connection. When the explicit proxy server allows the CONNECT method, the TLS handshake is sent, followed by the WebSocket connection upgrade handshake. In the case of transparent proxy servers, the browser is unaware of the proxy server, so no HTTP CONNECT method is sent. Figure 2 shows how using unencrypted WebSocket connections are more likely to fail in all but the simplest network topologies. Kaazing WebSocket Gateway features Web Socket emulation that makes Web Sockets available in all browsers, including those that don’t support Web Sockets. For example: If Kaazing WebSocket Gateway detects the presence of the Flash plugin, client libraries can take advantage of the single (Flash) TCP socket connection and if a direct connection is not possible (for example, if communication must flow through a firewall or an HTTP proxy server), then client libraries can still take advantage of the Flash runtime, minimizing the client's memory profile. If intermediate proxy servers lie between Kaazing WebSocket Gateway and a client, then a highly optimized encrypted streaming connection is used and the proxy-server-aware gateway automatically redirects the HTTP request so that it uses an encrypted HTTP (HTTPS) connection to make the proxy server agnostic to the streaming nature of the downstream HTTP traffic. This section describes how HTML5 Web Sockets work with load-balancing routers and firewalls. Since firewalls normally just enforce the rules for inbound traffic rejection and outbound traffic routing (for example, through the proxy server), there are usually no specific WebSocket traffic-related firewall concerns. Layer-7 load-balancing routers may be confused by WebSocket protocol upgrade requests when they are placed in the critical path between a browser and multiple WebSocket servers.
Once the load-balancing router has chosen a gateway instance, the gateway instance can then redirect the browser to connect directly to that active gateway instance.
While the HTML5 Web Socket protocol itself is unaware of proxy servers and firewalls, it features an HTTP-compatible handshake so that HTTP servers can share their default HTTP and HTTPS ports (80 and 443) with a WebSocket server.
If a browser is configured to use an explicit proxy server (for both encrypted and unencrypted WebSocket connections) then it will first issue an HTTP CONNECT method to that proxy server while establishing the WebSocket connection.

I agree with Martin on the fact the article tries to create an artificial distinction between Comet and WebSocket.
Thanks Mihai,I'd like to point out that most WebSocket servers don't try to provide emulation at all, so to access those, you would (today) need Chrome. Sidda,I hope that your optimistic prediction a€“ that all the browsers will follow Google Chrome to support WebSocket API a€“ will come true. Mihai,Kaazing provides an easy path for customers to move from Comet programming to standards based HTML5 WebSocket programming.
Web server is basically a program which delivers various contents like web page with the help of “Hypertext Transfer Protocol” commonly known as HTTP in the World Wide Web commonly known as WWW. To limit the uploading speed to prevent the server from going to saturation mode, thus helping in serving more clients with the available resources.
This is actually dynamic generation of web pages keeping Web site and Web server completely separate. This is done by properly managing the firewall protection to prevent unauthorized access from unknown IP. The configuration of the machine should be optimum with desired processor speed, RAM and proper cooling technology.
Linux is a versatile operating system in that it can be run on the slowest of PCs, at least in command line mode. Ubuntu supports a wide variety of video cards, hard drives and other hardware; if you want to check before downloading the install disk, look at the Linux hardware compatibility list for both complete systems and individual components in your system to see if it will work. If you need to change the BIOS settings to boot off of a CD then do so, or sometimes you need to press a key to select an alternative boot media.
Select “Download updates while installing” and “Install 3rd Party Software” and then “Erase and Use The Entire Disk”. You have a number of options here, but since most websites run on a combination of Apache, MySQL and PHP, we are going to install those.
Search for and install the following package names, each of which will include a number of prerequisites: apache2, php5, php5-mysql, and mysql-server. Part two of this series, to be published shortly, will go over how to upload files to your Linux web server; and how to access your web server both over your local network and via the internet.

Wonder whether the new Ubuntu is worth a shot, but found the official list of new Ubuntu features lacking in pictures and context? Communication is key to a successful family, and technology is great at helping us communicate. When it comes to cloud services for business, Amazon Web Services (AWS), tends to be one of the most popular options.
Since this is the first time we are doing this type of activity, the above should be considered loose guidelines.
For his day job, Patrick is a management consultant focused in the technology industry and has worked with numerous large hardware and storage vendors in the Silicon Valley. However, before you settle for the server, it is imperative that you understand how to build a home linux server.
You also need to take advantage of Imgburn program to burn the Iso and build your linux server. Today, there are many incredible websites that teaches you all you need to know on How to build a home linux server. These are all great no cost options for putting content online, but a poor substitution for a feature rich web server. This document provides hardware and software recommendations for building your very own Web Server all for under $250.
If you're not comfortable doing so, I would suggest having a friend help you out, or refer to one of the many tutorials available online. So for the benefit of anyone seeking some related hardware recommendations, here is my list.
Best thing of all is that there isn't a need to purchase a processor, video card, network adapter or heatsink with fan, everything we need comes with the Intel D525MW Mini-ITX Motherboard. So I've focused my efforts on selecting a Solid State Drive (SSD) that will provide better performance, low power consumption and generate no heat compared to a conventional mechanical hard drive with a large amount of disk space. Vertex 2 features the popular high speed Sandforce controller and high performance MLC flash memory. These 2GBx2, 204-pin SODIMM, DDR3 PC3-10600 memory modules will fully populate the dual in-line memory module slots on the motherboard with a maximum 4GB of system memory. With that in mind it was important for me to select products that conformed to our objectives. Not only does lessen physical footprint, but the heat generated is outside of the box, thus in turn providing better cooling and near silent operation.
A Broadband DSL, Cable or Fiber to the Home (FTTH) connection to the Internet is required to host your own web server.
If your Internet connection uses dynamic addressing and you have a domain name, I would suggest taking a look at a free dynamic DNS service.
Simply use a USB thumb drive to install an Operating System, or temporarily connect a SATA CD-ROM drive and remove once installation completes. A graphical desktop is not required as you'll most likely want to remote SSH into the server.
Unfortunately the installation and configure of Apache is beyond the scope of this article. This article explores this relationship further by demonstrating how it possible to build a simple container using less than 100 lines of Golang code. Serverless offerings have recently been receiving interest due to their simplicity, capabilities and potential for cost reductions. InfoQ interviewed him about applying leadership models, the Cynefin model and how it can be used for capturing requirements, scaling agile, and sustainable change. It introduces the WebSocket interface and defines a full-duplex communication channel that operates through a single socket over the Web.
Proxy servers are commonly used for content caching, Internet connectivity, security, and enterprise content filtering. Figure 1 shows a simplified network topology in which clients use a browser to access back-end TCP-based services using a full-duplex HTML5 WebSocket connection. Proxy servers may allow this and handle it gracefully, but they can also throw a monkey wrench in the works.
HTML5 Web Sockets feature an HTTP-compatible handshake so that HTTP servers can share their default HTTP and HTTPS ports (80 and 443) with a WebSocket server. Let’s take a look at unencrypted WebSocket traffic in two proxy server scenarios (explicit and transparent). When a proxy server forwards a request to the (WebSocket) server, it is expected to strip off certain headers, including the Connection header. For example, some proxy servers are configured not to remove the Connection: Upgrade header and pass it on to the WebSocket server, which in turn sends the 101 Web Socket Protocol Handshake response. If the proxy server has to participate in the Upgrade mechanism, additional proxy server configuration would be required, because a hop-by-hop transport is used; the Upgrade sent from the proxy server to the browser is only good for that one hop, and the proxy server must send its own Upgrade header to handle the next hop from the proxy server to the WebSocket server (or to yet another intermediary server). In the future, however, proxy servers will likely become Web Sockets-aware and able to properly handle and forward WebSocket traffic. After those handshakes succeed, WebSocket traffic can start flowing unimpeded through the proxy server.
However, since the wire traffic is encrypted, intermediate transparent proxy servers may simply allow the encrypted traffic through, so there is a much better chance that the WebSocket connection will succeed if Web Sockets Secure is used.
Figure 2 shows the decisions that are made during the setup of a WebSocket connection between the browser and the WebSocket server. It all comes down to understanding the end-to-end network topology you are deploying your WebSocket application in.
In a production environment it would be anticipated that HTTPS streaming can be used as a worst-case scenario to fall back to.
For that reason, Layer 7 load balancing routers may need to be configured to be explicitly aware of WebSocket traffic.
For this reason, services running on Kaazing WebSocket Gateway support peer load balancer awareness, which allows the load-balancing router to be configured as a peer next to WebSocket servers.
This means that the load-balancing router stays out of the way of the actual WebSocket traffic, thus reducing latency. However, each request and response carries with it lots of unnecessary HTTP header overhead and latency.
Some proxy servers are harmless and work fine with Web Sockets; others will prevent Web Sockets from working correctly, causing the connection to fail.
However, since the wire traffic is encrypted, intermediate transparent proxy servers may simply allow the encrypted traffic through, so there is a much better chance that the WebSocket connection will succeed if an encrypted WebSocket connection is used. If intermediate proxy servers are detected, then a highly optimized encrypted streaming connection is used for the downstream HTTP traffic.
Peter is the co-author of the Apress book Pro HTML5 Programming and teaches HTML5 training courses. Peter also develops documentation automation solutions and two of his inventions are patented. WebSocket is just an interface for a Comet implementation for the large majority of the existing browsers.I don't try to defend Comet as I think it is not a very well established term. Given this reality, any WebSocket server a€“ including Kaazing WebSocket Gateway a€“ necessarily emulates its API using different ad-hoc techniques for the major browsers. Thanks to Google, W3C and IETF we are now moving towards a sensible and a scalable solution to achieve pushing data from server to webclients in real-time. I also hope that all the browsers already installed will be replaced with browsers supporting WebSocket API.But what customer will deploy a real-time web technology that supports IE6, IE7, IE8, Firefox, Opera (including mobile version), and Safari (including iPhone) through a bunch of hacks == Comet?
To provide maximum return on customers' investments in new applications based on HTML5 WebSocket API - Kaazing emulates HTML5 WebSocket API for older browsers so customers don't have to program against a different Comet like API separately. This limit depends upon the software and hard ware limits of the operating system used, type of HTTP request, cache memory of the server and the dynamic and static content origin setting of the web server.
The “HTTP traffic managers” should be maintained properly to rewrite, redirect and drop requests from bad HTTP. Installing Linux on a spare old computer is a pretty easy thing to do these days with many consumer friendly distributions such as Ubuntu and Mint Linux.
For simplicity’s sake, we are going to be running Ubuntu 10.10 “Maverick Meercat” which was just released and reviewed by Justin. The installation itself takes up 3.3GB and then you want to leave space for the additional software and any files you need to work with, so I would peg that minimum at 10GB. Before getting too caught up in this though, it is pretty quick and simple to test things out with a Live CD to make sure everything will work on your system. It is better to place it in an air-conditioned room during the summer as heat will be your system’s main enemy.
My favorite feature of the installer is that while you are still making choices about the installation, it is working to format and copy files over to your hard drive. These disk images have the latest versions of software so you should only have to do a minimum of upgrading after the install. The first thing you need to do after an install, similar to a Windows machine, is to apply any updates. Should I do a complete re-installation of whatever Linux version I want to use if I want to try that clear-OS?
Our judgement is in no way biased, and our recommendations are always based on the merits of the items. On Windows, you bring up the task manager using Ctrl + Alt + Delete to confirm your suspicions. The goal of STH is simply to help users find some information about basic server building blocks.
For a virtual machine, it is recommended that you get 2 GHz and 2GB to have more than enough just in case you need extra space.


I assume you have such a service and fully understand that performance will vary based on connection speeds. Also while we're on the topic of connectivity, be sure to forward port 80 to the web server if using a router.
Also, for the sake of security, I'd strongly advise you to use SSH public key authentication and change the default SSH port.
However, I do plan on writing a HowTo install & configure Apache document at a later date. HTML5 Web Sockets effectively provide a socket connection over the Web with minimal overhead. Without any intermediary servers (proxy or reverse proxy servers, firewalls, load-balancing routers and so on) between the browser and the WebSocket server, a WebSocket connection can be established smoothly, as long as both the server and the client understand the Web Socket protocol.
Some clients are located inside a corporate network, protected by a corporate firewall and configured to access the Internet through explicit, or known, proxy servers, which may provide content caching and security; while other clients access the WebSocket server directly over the Internet. To establish a WebSocket connection, the client and server upgrade from the HTTP protocol to the Web Socket protocol during an initial handshake, as shown in Example 1. Therefore, a well-behaved transparent proxy server will cause the WebSocket upgrade handshake to fail almost immediately. Problems then arise when the client or the server starts sending the first WebSocket frame. HTTPS (HTTP over TLS) work the same way; the use of encryption typically triggers the HTTP CONNECT method.
Therefore, it is always best to use Web Sockets Secure with TLS encryption to connect to a WebSocket server, unless you're absolutely certain there are no intermediaries.
Some HTTP proxy servers may restrict ports or allow access only to specific, authorized servers.
However, for this to work the Gateway has to be configured with a suitable certificate for TLS encryption. One major benefit of using Kaazing WebSocket Gateway and its Web Socket emulation is that you can code applications against the HTML5 Web Sockets standard, today, and these applications will work in all browsers. This way, the load-balancing router handles only the initial client requests and discovers the best active gateway instance to route traffic to.
In case of a hardware failure or network error, however, the clients will auto-reconnect to the load-balancing router, which automatically forwards those requests to another active Kaazing Gateway instance. In some cases additional proxy server configuration may be required, and certain proxy servers may need to be upgraded to support Web Sockets. This is made possible by Kaazing's underlying support for cross-origin HTTP and HTTPS requests.
You seem to want to distance Kaazing from Comet, despite the fact that your WebSocket emulation is surely Comet. The bottom line is that it is best to use WebSocket Secure and, surprisingly, the encryption does not add all that much extra overhead. On one side you have Google pushing for open standards and with its kick-ass browser implementing the same (other browser vendors don't have a choice but to follow, or should I say catchup).
Kaazing's implementation of the HTML5 WebSocket API emulation is better than the competition - as independently verified by a customer. In commercial field, the server is responsible for providing network connection to a larger area, the server computer is rack mounted along with other servers to regulate such a tremendous job.
Sometimes due to various factors like excessive web traffic, XSS viruses, computer worms, network slowdown and many other reasons the load limit crosses and then the server stops responding . Traffic shaping and Bandwidth management should be done properly to improve the server working. After getting up and running you will have a platform for hosting your website in-house either for development or to self-host a website. The second is that it also opens your system up to more potential security holes in the future.
THank you for your comprehensible tutorial Dave, I am learning Linux after 10 years of Windows, and what a relief!
Ideally I want to be able to store all my music and movies on the server and access them from my pc – is this something to do with the shared folder? Using a few components sitting around is perfectly fine as this is not a contest, just a fun activity to benefit charities folks are involved in.
Some common considerations when building a Web Server are performance, form factor (size) of components, cooling, storage capacities, minimal acoustics (noise reduction), compatibility and cost.
Front panel features two USB 2.0 ports, 1 eSATA, and an audio (AC'97 and HDA compatible) In and Out. You may also want to check out our learing about Linux guide or reference some of our easy to follow Linux HowTos.
This delivers an enormous reduction in unnecessary network traffic and latency compared to legacy polling and long-polling (Comet) solutions that are often used to push real-time data to clients or even simulate a full-duplex connection by maintaining two HTTP connections. Proxy servers can monitor traffic and close a connection if it has been is open for too long. However, in real environments, lots of network traffic is routed through intermediary servers. In both cases, the client requests may be routed through transparent, or unknown, proxy servers (for example, a proxy server in a data center or a reverse proxy server in front of the remote server).
Once established, WebSocket data frames can be sent back and forth between the client and the server in full-duplex mode. Since the frame does not resemble anything the proxy server might expect (such as regular HTTP traffic), some exception will likely occur, unless the proxy server is specifically configured to handle WebSocket traffic.
A WebSocket server that is used in such a scenario must be added to the white list of servers for connections to be successful. Without that (this should be considered a configuration error), Kaazing will fall back to an advanced non-streaming implementation. Alternatively, the proxy server may be configured to disconnect HTTP connections that are kept open for a certain amount of time.
More than this though, WebSocket itself is also Comet since Comet is just a paradigm, not a any specific transport mechanism. We have actually seen things speed up in some scenarios.I don't agree with you (and Mihai) when you say that WebSocket is the same as Comet.
On the other side you have a practical solution with comet, stitched together with bandages. We at Migratory Data Systems consider that Comet is an established and proven technology deployed in large production systems. Kaazing also supports the new EventSource API in HTML5 specification, for those interested in doing Comet style data fetching (from server to client only).
Their goal will be to use a $200 gift to scour the web for deals and build the best server for charity that they can. There is also a half height expansion slot in the back with side cooling vented by an 80mm TriCool 3 speed exhaust fan.
In this article, I’ll explain how HTML5 Web Sockets interact with proxy servers, load balancing routers, and firewalls. It is even possible for proxy servers to have their own explicit proxy servers, increasing the number of hops the WebSocket traffic has to make. Here is how I see it: Comet is a programming model that allows a web server to push data to a browser. Web applications of the future will need the full-duplex communication channel provided by HTML5 WebSocket. This delivery data includes HTML generated documents, including style sheets, images, java scripts and other related data. Additionally, I’ll explain how Kaazing WebSocket Gateway and its Web Socket emulation can add additional value. In the future, WebSocket gateways and servers may even be able to dynamically upgrade to Web Sockets Secure if an uncooperative proxy server is detected. Google recently announced Quake II on HTML5 technology and it uses HTML5 WebSocket for bi-directional data. Additionally, proxy servers may also buffer unencrypted HTTP responses, thereby introducing unpredictable latency during HTTP response streaming.
This is still better than other Comet solutions though, because those simply use (or fall back to) long-polling. This is because the user requests for a web page to the web browser, the web browser then finally communicates with the server to request for that page by using HTTP, then ultimately the server responds to that request by providing the contents of that page or displays an error message if unable to do the needful. Along with this a server is also embedded with webcams, printers or routers and also local networks for direct data transfer through LAN instead of HTTP which is much faster. Web servers sometimes integrate with system components and thus helping in monitoring and administrating the system devices. The hope is that people get creative.What we are looking to do is build servers for charity. Thus the web server itself helps in maintaining the system thus no additional software is required. The hope is that the two individuals will build the best server they can using a constrained budget. For those that do not this this is possible, a dual Intel Xeon L5430 machine with hard drives and 12GB RAM runs for around $150 these days (example here) so there is plenty out there to choose from.
